Programming
All readable and adjustable values (parameters) of the TKx units are listed
on several pages. While normal operation or if no key is pressed for about
3 minutes, the display shows the following information:
1. priority: current failure (only if there is a failure at the moment)
2. priority: controller states (e.g. if it is turned OFF by a digital input)
3. priority: the selected 'Basic Display'
Call up and changing of parameters:
Key Action
ESC .......If no pagename is displayed
........Select desired page
RET ........Enter this page
........Select parameter
RET ........Start programming, parameter name flashes.
Eventually, the unit asks here for an access code
........Adjust desired value. Pressing and holding a key effects
that the value will be incremented or decremented
automatically faster and faster.
RET ........Leave programming mode, confirm new value
ESC ........Back to page overview.
Identification
If this display appears
then this parameter is protected by a password. The controller expects
a code number. This code-no. (Code 1) is related from the actual time of
the day as the sum of the hour (0...23) plus 10
Changing User level
To change the user level do the following:
Select "Basic Display", press key "RET"
Enter code of the desired user level
- Code for the service level is: (fixed) - 88 -

CONNECTION INFORMATION & SAFETY INSTRUCTIONS
Product warranty does not cover damage caused by failure
to comply with these operating instructions! Nor will ELREHA
be held liable for any personal injury or damage to property
caused by improper handling or failure to observe the safety
instructions and recommendations contained in this or any
other ELREHA supplied document related to this product!
Thismanualcontainsadditionalsafetyinstructionsthroughout
the functional description. Please pay close attention to these
instructions!
TO AVOID RISK TO HEALTH OR POSSIBLE LOSS OF
LIFE, DO NOT OPERATE IF:
• The device has visible damage or doesn't work
• After a long storage period under unfavourable conditions
• The device is heavily soiled or wet
• When shipped under inadequate conditions
• Never use this product in equipment or systems that are
intended to be used in applications or under circumstances
that may affect human life. For applications requiring
extremely high reliability, please contact the manufacturer
before use.
• This product may only be used in the applications
described on page 1.
• Electrical installation and placement into service
must be performed by qualified personnel only.
• To avoid the risk of Electrical Shock, all ‘PE’ terminals
must be connected to ground. Without adequately
grounding the unit, the internal noise filter will not work,
whichcancausefaultyreadings,orinaccuratedisplayed
values to occur.
• Never operate the device without the supplied
enclosure.
• To prevent electrical shock, the device may only be
operated in a closed control cabinet or control box.
• Be sure to observe all local, state, or federal safety
regulations in the location that the unit is installed.
• Before installation, verify that the control specifications
suit the application details. Damage may occur if the unit
is operated outside of its specified limitations.
Examples:
- Supply voltage (printed on the type label).
- Environmental limits for temperature/humidity.
- Maximum current rating for the relays.
• Do not install sensor cables in parallel to high current
cables. Shielding must be connected to PE at the end
close to the controller. If not, inductive interferences may
occur. The wire gauge should be no less than 0,5mm².
• Mounting the controller close to power relays is not
recommended, due to the risk of strong electro-magnetic
interference, which can cause the unit to malfunction!
• Ensure that the interface wiring meets all the necessary
requirements.
• All used temperature sensors must be identical. Never
use different types at the same time. This will not work.

Failure Messages / Failure Memory / Failure Codes
All failures will be stored with date and time of their appearance. To display this messages, 2 pages
exist:
- The "Actual failures page" contains all current failures in a short form. To make more than one
current failure visible, use the 'up/down'-keys. If a sensor is short or broken, this message also
appears on the actual value display.
- The "Historic failures" page contains the last 15 failures with date and time of their appearance.
Failure Codes
---- ............no failure
Init ...........first initialisation of the controller or data lost
Hard ........- hardware failure (from SoftwVers. 6.xx): Internal battery voltage low
MOFF ......mains supply cut off

If a sensor is short/broken, a time delay of 5 seconds takes effect before an alarm will be activated.
HT X ........one of the alarm sensors of circuit X high temperature
LT X .........one of the alarm sensors of circuit X low temperature
MRC X cooling of circuit X has exceeded maximum runtime. (only active up to 'runtime mess at').
OPC X .....alarm on digital (OC) input X, assigned as alarm input
DOR X .....door contact of circuit X open too long. (only active up to 'runtime mess at').
DEF X .....number of defrost cycles without termination by temperature exceeded in circuit X,
maybe too many ice or heater malfunction.
ASSI ........error on assignment page, e.g. function programmed too often
COon .......controller unit switched ON by interface or by digital input
COof .......controller unit switched OFF by interface or by digital input
OFF X .....circuit X switched off by interface or by digital input
Display of actual values and states
All actual values are shown on the 'actual values'
page.
Display of the temperatures
'sensor1' to 'sensor 6' display their actual value in
the range of -50 ... +100°C. At the same time, the
display shows the functions which are assigned to
the sensor.
Sensor corrections can be made by editing
each individual sensor reading. The resulting
correction factors are listed on the mode page
(corr sensor 1-6).
Setpoints:
The active day
or night setpoints
are indicated on
the display by „->“
and „<-“.
Information about delay times
Onthe actual valuespageyouwillfindallremaining
delay times, so it is easy to verify the points in
time when specific functions must start.
Status Displays
Temperature Sensors
There are two types oftemperature sensors which
can be used:
- TF 201, PTC sensor (2000 ohms@25°C),
!! not 3130/1 !!
- TF 501, PT1000 sensor (1000 ohms@0°C)
The type must be preset by 'sensor' (mode
page).

'Standard Display' - Function
After switching on the controller, the display will
indicate the 'Standard Display' after some seconds
(in case of a failure it will display the actual failure).
factory set is the actual value of probe 1.
This will also displayed if you have selected any
parameter and you haven’t touch a button for more
than 3 minutes. If you think that it is suggestive to
show any sensor value as permanent parameter,
do the following:
Change permanent parameter
- Select the parameter you want to have as
'Standard Display'
- Press "" and "" simultaneaously.
The display becomes dark for a moment, after
that the selected parameter will be shown as
the "standard display".
Configuration Concept
The TKx controllers series has a ´free configu-
rable concept', that means all in/outputs have no
fixed functions. All inputs and outputs (6 relays, 6
sensors, 4 digital (OC)-inputs, 1 analog output) can
be configured to work with any integrated control
functions or all of the 4 control circuits.
Sensors
Each sensor is able to fulfill up to 3 functions at the
same time (function sensor X a, function sensor X
b, function sensor X c, X = sensor no.). e.g.:
1. control sensor and alarm sensor simultaneous-
ly
2. controlsensoranddefrostsensorsimultaneous-
ly, e.g to control a chi ller
cabinet at the air outlet.
Virtual Sensors
Up to 6 probes can be combined to a "virtual" sen-
sor, which allows an average determination with
adjustable quantifying.
Digital Inputs (OptoCoupler Inputs)
Each digital input can be assigned to one of the
possible functions.
Relay Outputs
Eachrelaycanbeusedtocontroloneofthepossible
functions.The same function can even be allocated
to multiple relays.
Parameters
Parameters of functions which are not assigned
will not appear in the parameter pages to improve
survey.
Assignment
The function of each input and output can be preset
on the 'assignment page'. The assignment can be
done by the keys or via interface.
Example of a configuration for a freezer with 3
evaporators:

User levels
To avoid parameter changing by unauthorized persons, 3 different user levels
are available:
1. Customer Level
In this level setpoints can be changed, but it is impossible to change
the configuration of the unit.
2. Service Level (call-up with code 2)
Here the service contractor finds parameters and information for
start-up and service.
3. Configuration Level (call-up with code 3)
Here you can change all parameters, even the fundamental functions
to assign inputs and outputs.
In the single levels only the accessable parameters will be displayed (marked
by 'Level 1,2,3' on the parameter pages).
Using the Access Protection
The parameter „operator layer“ on Mode Page is factory set to „no“. Thus
you will see all parameters, the same as if the 'Configuration-Level' would
be active.
After start-up, you protect the controller unit effectively by changing parameter
„operator layer“ (mode page) to „yes“. If you don’t touch any key for at least 3
minutes or if you switch off power for a moment, the protection will be activated.
Thus only the parameters of the Customer Level can be displayed.
All other parameters are hidden now and can be accessed only by knowing
the code.
To change from Customer Level to Service- or Configuration Level do as
follows:
•
Select 'basic Display',
•
Press key "Prog",
•
Enter code for desired level.
Change parameters
To change a parameter in the single user levels, the unit frequently expects
an additional 'Identification Code'. (see right column).
As long as parameter "operator layer" is not set to "no", the unit changes to
the Customer Level if no key is pressed for about 3 minutes.
Parameter Protection / Identificaton
Almost all parameters, except the temperature setpoints, are protected
by a simple password.
If you have to change a parameter and you have pressed the "RET"-key,
this display appears:
The controller expects now the input of a code-no. This code-no. (Code
1) is related from the actual time of the day as the sum of the
hour (0 to 23) plus 10
Example:
At 9:35 a.m. the code is 9 + 10 = 19.
At 21:35 (9:35 p.m.) the code would be 21 + 10 = 31.
If you have pressed no key for about 3 minutes, the parameters are
locked again automatically.

Codes for Customer Levels
Code 2: ......Fixed Code: - 88 - (calls up Service Level)
Code 3: .....Month + Hour + 20

Example: (Note: Real-time clock must be set to the
right time and date before.)
You want to change a parameter at a day in june at 9:35
in the morning. Identification Code = 6 + 9 +20 = 35.
Unit Text
In the mode page you have the possibility to define a specific text (max.
16 characters) for the controller, e.g. „meat-store“. This name will be
indicated on the screen of the VPR compound controller or on a PC with
matching software.
Change text:
• select parameter „unit text“ (mode page)
• „RET“ Start programming, the first character position flashes
(eventually, you must enter the access code before)
• "" change character
• „RET“ the next character flashes
• "" change character
....and so on
• press „RET“ to confirm the last character.
Changing the text can also be made by the software 'COOLVision' or 'CV-
Scheduler'.
Display Language
The language used on display can be changed by "Sprache/Language"
(mode page) to german, english, french or dutch.

'Physical' and 'virtual' sensors
1. Each 'physical' (real) sensor is able to fulfill up to 3
functions at the same time (see Assignment Page),
any sensor is able to do the same job.
Up to 6 control sensors can be assigned the same
time. The warmest of them initiates the cooling
function.
2. It is possible to create a 'virtual' sensor to realize
different kinds of averaging, e.g. multiple sensors in
a huge room or averaging of inlet and outlet sensor
in a chest freezer. The 'virtual' sensor resp. value
(sensor 7) follows from the selectable emphasis of
the sensors which must have an effect on the result
(weighting 1-6, Assignment Page). The functions
assigned to this 'sensors' (funct sens. 7a-c, As-
signment Page) are the same as the functions for
the 'physical' sensors.
Example: If the 'physical' sensor 1 got the function
"con" (control sensor) and also the 'virtual' sensor,
then the warmer one initiates refrigeration.
● Selectionofa"virtualsensor":
- Assignment of a function by "funct sens7a-c"
● Selectionofa'physical'sensorwhichmusthave
an effect on the result :
- Activating of the sensor by assigning a
function (e.g. display only sensor)
● Setweightingfortheselectedsensor
(weighting 1-6).
The sum of all emphasis values must be
100%. Example:
Ifsensor1andsensor2musthaveaneffecton
the result and you set "weighting 1" to "30%"
and "weighting 2" to "60%", then you get the error
message "SEL" (assignment error).
Further causes for the error message "SEL"
● Thesumofallemphasisparametersis100%,
but no virtual sensor function is selected
● All4emphasisvaluesaresetto'0'anda
'virtual' sensor function is assigned
● Aphysicalsensorisswitchedoff,butan
emphasis value > 0 is selected.
Example 1, Chest Freezer:
For the detection of the actual value, inlet and outlet
sensor must be used. Sensor 1 is mounted at the
suction side (inlet) and must have an 60% influence
on the result. Sensor 2 is mounted at the outlet and
must have an 40% influence.
- set "weighting 1" to "60"
- set "weighting 2" to "40"
- set "funct sensor 7a" to "con" (control sensor)
Example 2, huge room, standard application
Sensors 1-3 must measure the rooms temperature,
anarithmeticaveragemustbecalculated,sensor4is
the defrost limitation sensor in the evaporator.
- set "weighting 1+2" to "33" and "weighting 3"
to "34"
- set "funct sensor 7a" to "con" (control sensor)
- set "funct sensor 4a" to "df1"
Special Function
If an emphasis parameter value is set to
100% (others to 0), up to 6 functions can
beassignedtothecorrespondingphysicalsensor.
This may be of interest for applications where
more than 3 sensor functions are used.

Caution
Cooling
Control circuits
Thiscontrolleris ableto controlupto 4independent
cooling circuits, each with an own setpoint.
Cooling
Cooling is controlled by switching the output relay.
In case of power loss or controller defects the
contacts must switch in a position which is safe for
the application. For this reason we are using the
N/O-contactforrefrigerationapplications (fail-safe:
open contacts). For freezing applications we use
the N/C-contacts (fail-safe: closed contacts).
This can be set by parameter "cooling mode"
(mode page). The point of cut-off is always the
valid setpoint. The selection of this parameter
also affects to the switching characteristic of the
fan relay.
Therefrigerationrelaycanbedisabled via interface
(see chapter "networking via E-Link").
Low temperature Limitation
Can be used e.g. for refrigerated shelfs with roller
blinds to limit the temperature at the air outlet du-
ring night operation. When the temperature at the
alarm sensor falls below the limit set by "warn low
limit" (Setpoint page) cooling will switch off. This
value is the threshold for the undertemperature
alarm at the same time.
The undertemperature limitation cannot
be switched off and is also active with
disabled low temperature warning.
Refrigeration delay after power up
The start of refrigeration after power-up resp.
mains loss can be delayed by parameter "re-
frDlyAftMnsOff" (Setpoint Page). In plants with
many cold storages this function prevents that
after power-up all solenoid valves open at the
same time, even though not enough machine
power is present yet.

Heating function
For one relay it is possible to assign the function
of heating circuit 1. The setpoint is the cut-off of
heating and cooling at the same time:
•
for cooling at setpoint + hysteresis and
• for heating at setpoint - hysteresis.

Runtime Monitoring
The controller monitors the total running hours per
day ofthe coolingoutputs.This valuesare displayed
under parameters „run time refr. x“ for each circuit.
One day counts from the time of the parameter
„runtime mess at“ (mode page) until the same time
of the next day.
Example:
"runtime mess at" set to 11:00.
Monitoring time range is from 11:00 o'clock day 1up
to 10:59 o'clock day 2.
The total runtime of the cooling relays over a day
will be stored and displayed ("runtime refr. 1-4",
Actual Values).
Aparameter „coolinglimit“canbe settoa reasonable
value (hours per day) which, when exceeded on
three days in a sequence, will cause an alarm at
the hour programmed by „runtime mess at“. Then
the alarm relay will be de-activated and the alarm
LED goes on.
This alarm will be cancelled automatically 1
hour later.
Operation with a single compressor
If a single compressor is controlled by a refrigeration
relay, it is suggestive to have an idle time to prevent
the machine from damages caused by short cycle
operation.The compressor can restart only after the
timer"compr.pause"(setpointpage)isrundown.The
remainingtime up to thecompressorsrestartcanbe
read at "rem.compr pause X" (actual page).
If a compressor must be controlled directly,
never use the cooling mode 'freezing' to
prevent compressor damages by conti-
nuous running!
Second setpoint (night operation)
For each of the 4 circuits a second setpoint is avai-
lable (2nd setp Ch X). This can be used for night
operation or other energy savings. The toggling
betweenthesesetpointscanbemadebytheinternal
clock or by a digital input. The setpoint which is in
use at the moment is marked by two arrows like:
„—> -20,0°C <—“. In the actual values page you
see also if day or night setpoint is in use.
Internal toggling
The parameters „night setpt ON“ (mode page)
and „night setpt OFF“ determine the period
when the 2nd setpoint will be active. If the
function 'night settings' is assigned to one of the
digital inputs, it must be connected to mains
phase. If the internal timer is not used, set
'night setp. ON' and 'night setp. OFF' times to
„OFF“.
External toggling
If the 'night settings' input is open, the 2nd
setpoint is activated all time and the internal
timer is disabled. With this digital input to mains
phase, the normal (1st) setpoint is activated
and internal timer is enabled.
Second Set of Setpoints
The controller offers two sets (layers) of setpoints,
where the first layer of setpoint is used during normal
operation and the alternative layer of setpoints with
other temperatures is used e.g. for other products
which will be stored only sometimes. For each layer
there are parameters for the setpoints, the night
setpoints, warning offsets and low temperature
warning. The names of the second set parameters
begin with 'alt....'.
Toggling between the setpoint layers
1. internal: with parameter „setpoint layer“
2. external: assign function „setpoint layer“ to
a digital input. If connected to mains
phase, the 2nd layer is in use.

Temperature Alarm
Any over- or undertemperature condition results
in a temperature alarm which causes the normally
energized alarm relay to de-energize. Hereby the
N/O-contacts open and the N/C-contacts close.
To avoid an alarm for short irregular conditions there
is a delay time („warning delay“, setpoint page). The
alarm condition is indicated by a LED at the front of
the controller. The alarm

Digital inputs (Optocoupler Inputs)
Switching OFF Controller / Cooling Circuits
Sometimes it is necessary to switch off cold storages
completelyincludingthecontroller,butifthiscontroller
works in a network, the bus-master detects a mal-
function and generates an alarm.
Controller Off
If a digital input is assigned to the function „Unit OFF

tionsaredisabled.Thedisplaycontinuesworking,but

of the 'historical failures'. „Unit OFFactLow“ disables
the functions with 0V at the digital input.
Circuit Off
Each digital input can be configured to switch off one
oremorecoolingcircuits("circuitOFFX").Ifactivated,
all regulation and control functions and temperature
alarms of the concerned circuits are disabled. Never-
thelesstheothersarestillworking.This is memorized
in the list of the 'historical failures'.
Relay function 'unit on'
The function 'unit on', assigned to an output relay,
has the effect that this relay keeps switched on
during normal operation and keeps switched off
while the controller unit is disabled by digital input or
by interface. So this relay can be used to switch a
function which should be active while the controller
unit does not work.
Safety Chain Monitoring
While using the controller for single compressor
applications, one of the digital inputs can be used for
monitoring the safetydevices ("security chain") ofthe
compressor. Normally the digital input is connected
to phase. But if the input is open, the controller waits
for the timer „sec chain delay“ (setpoint page) then
cooling and fan are switched off, a running defrost
period is terminated and a new defrost start is impos-
sible. The alarm relay will be activated. Parameter
"rem strt sec ch" shows the remaining time up to a
controller unit response.
Door Contact Input
Each control circuit can get a a door contact input. If
the door contact input is connected to phase, the fan
of the circuit stops immediately. If the door is open >
3 minutes, cooling will stop too. Parameter "status"
shows the circuit which is switched off. If the door is
open > 5 minutes, the failure message "door X" will
be generated. Cooling and fan will restart:
- if door is closed or
- if temperature exceeds the warning limits or
- if door opening exceeds the time set by
„door alm delay“ (setpoint page). At the same
time the alarm relay will be activated.
Door Open monitoring
Each time when door is open, the controller adds this
time to the total opening time of that day „door open
x“ (actual page). If the total opening time exceeds
the time set by „door time limit“ (setpoint page) then
an alarm will be generated. The failure message
will be forwarded at the point in time determined
by „runtime mess at“ (mode page) and is cancelled
automatically 1 hour later. "rem door open 1" thru
"rem door open 4" show the remaining time up to
the alarm message.
Light
One of the relays can execute the function „light“,
suitable to control lightings. In this case, the relay
switches together with the night settings „night setp.
ON“and„nightsetp.OFF“(modepage).During„day“
the relay is activated.
External Alarm
The digital inputs can execute the job „alarm input
x“. While normal operation, the input is connected
to mains phase. When the voltage drops down, a
delay time starts „OC inp alm delay“ (setpoint page).
After this timer is run down, a failure message will
be generated.

Real Time Clock
The built-in real time clock is buffered for a period
where mains voltage is switched off (3 years up to
softw.vers. 6.9, appr. 10 days from softw.vers. 7.00).
Date and Time can be set on the 'mode page'.
Factory set is a GMT +01:00 ('timezone offset'=
60 min.), which is valid for mid europe. If the con-
troller is used in other zones, the values can be
readjusted.
Summer/Winter Time (Daylight Saving Time)
Switching / Time Zones
An automatic summer / winter switching (parameter
„summer/ winter“) considers the current EU-rules
from 1996 (EU 96), but it can also switched off or
set as necessary.

By parameter "timezone offset" the summer/winter
time switching can be adapted as necessary.

Analog Output
The controller contains an analog output which
can be used for regulation or to provide a remote
display with an actual value image. The signal
is available as a DC-Voltage or a DC-Current-
Signal.
Parameter „analogvalue“ (actual page) shows the
current output signal as a %-part of the selected
range, "analog function" (assignment page) de-
termines the behaviour of the output:
Test functions (output delivers fixed values only)
0V = voltage = 0V, current = 0 mA
4mA = voltage = 2V, current = 4 mA
10V/20mA = voltage = 10V, current = 20mA

To adapt the controller to the process use the
following parameters:

to 'setpoint Ch 1'
" PID integr time" .......integral time (I-part)
" PID attack time" ....... derivative time (D-part)
" PID delay" ............ actuator response time

How to affect the analog output manually
For certain operations it might be usefull to affect
the output signal manually. Therefore the function
„analogvalue“ (assignment page) can be assigned
to one of the digital inputs.
Applying mains phase to a configured digital input
the analog output will be forced to the value (in %)
that is programmed by „opto->analogout“ (setpoint
page). So e.g. a connected valve drive will be set
to a specific position.

Defrost
The controller allows several, different defrost me-
thods. This methods are available for each of the 4
possible control circuits, that means it is possible to
assign 4 defrost channels, each with an own relay.
This relay output(s) are able to control an electric
heater or fan for defrosting the evaporator(s).
Each evaporator with electric heater is monitored by
adefrostsensor.Accordingtotheapplication,choose
if the fan must stop or run during defrost (parameter
„defrost type“ on or off).
● „defrost mode“ (defrost page) determines how
defrost starts:
- extern(al)
defrost starts only when the digital input (OC-
input) is activated
- extern+intern
defrost starts by digital input or by internal clock
- difference method
defrost on demand method which uses two
supplementary sensors to measure the
temperature difference across the evaporator
- dem defr by opti(mization)
defrost on demand method, defrost is started by
the clock, but the pauses between the defrost
cycles will be calculated
- adaptive
defrost control by the intelligent, adaptive
function (only TKP/TKC x140, c.f. next pages)
An electric defrost heater is switched by the N/O-
contact of the defrost relay independent from the
application (refrigeration/freezing).
Cooling is disabled during defrost automatically.
"lastdefrcycle1"thru"lastdefrcycle4"(defrostpage)
show the expired defrost time of each circuit.
Defrost start by clock
Abuilt-in timer allows you to set up to six (6) different
times for defrosting within 24 hours („defrost time 1“
to „defrost time 6“, defrost-page). To disable these
parameters, set them to „OFF“.
The defrost cycle starts only, if the temperature at
one of the evaporator sensors is below the limitation
setpoint "defr temp limit X".
If parameter „defrost mode“ on the mode page is set
to „external“, the timer function is disabled.
Please note that this function differs
with 'adaptive' defrost
Remote Defrost Initiation
To start defrost by digital input, note that mains phase
has to beappliedfor2 seconds minimum and lastnot
longer than the shortest possible defrost cycle.
Pause ahead defrost
The parameter 'pause ahead defr' (Defrost Page)
causesthat thedefrost heaters willswitch on delayed
atthebeginningofadefrostcycle.Thisgivesachance
to pumpdown the evaporators before heating. So
the defrost heaters need less energy, because the
evaporator is already warmed up.
Defrost termination by temperature
Defrostwillbeterminated(individuallyforeachcontrol
circuit)bythecorrespondingdefrost(evaporator)sen-
sor. This sensors must be placed at a position where,
by experience, ice remains the longest time.
Notice
If the temperature rises at that position, the ice in
the evaporator is probably melted completely. A
defrost cycle ends as soon as all defrost sensors
have reached the defrost limitation temperatures
„defr temp limit X“ (defrost page) or the safety time
„max defr Time“ (defrost page) has been expired. If
2 defrost sensors are assigned to one circuit, both
sensors must reach the limitation temperature to
terminate defrost.
Defrost termination by time
Incasethatno defrost sensors areassigned orifthey
are out of order, the defrost cycle will be terminated if
„maxdefrTime“(defrostpage)isachieved.Parameter
„remain defr time“ (actual page) shows the time until
expiration of this timer.
Defrost termination monitoring
Normally, a defrost period should be terminated if the
temperature in the evaporator reaches the limitation
setpoint. In case of bad working conditions like to
many ice or a defect defrost heater, defrost is ter-
minated by „max defr time“. If the number of defrost
periods terminated by timer exceeds the number
programmed by parameter „n/o .def evnt>alm“, a
failure will be indicated.
In case of defrost by airflow without evapo-
rator sensor, this function has to be disabled
(„OFF“), because here every defrost cycle is
terminated by the timer.
Cooling Delay (drain time)
With „pause aft defr“ (defrost page) you can set a
duration where the solenoid valve(s) are disabled
after defrost termination. The remaining times can
be read at „remain defr pause 1“ up to „remain defr
pause 4“ (actual values page).
Manual Defrost
A manual defrost initiation via button is possible and
prior at any time.
Start : Select „manual defrost“ (defrost page).
Confirm „start“
Stop: Confirm „finish“.
Pulsed Defrost
To save energy and to avoid creating too much moi-
sture it’s possible to work with a pulsed (switched in
intervals) defrost function.
If the evaporator temperature is between „pulse def
limit“(defrostpage)andthelimitationtemperature(the
value of „pulse def limit“ must be lower than limitation
temperature), the controller determines about the
optimal heat distribution in the evaporator depending
on the gradients of the temperature. If the evaporator
temperature reaches „pulse def limit“, the heater is
not longer heating continually but will be switched on
and off by the controller in calculated periods until the
defrost limitation temperature is reached.
As a result of this procedure
● heatenergydistributionintheevaporatorisbetter
●thedefrostlimittemperaturecanbesetlower
●therislessfog/humidityinthechamber
●youareabletosaveenergybecauseofthe
optimized temperature distribution and the lower
limitation temperature.
To disable this function, set „pulse defr limit“ to a
very high value.
Defrost on demand - Standard methods
Optimiziation Method (for walk-ins/rooms)
With every requested defrost cycle the controller
detects the actual period of time needed for mel-
ting the icing at the evaporator around freezing
point (between -2°C and +2°C). This time has a
dependent relationship on the number of defrosts
needed per day or, with other words, how many of
the programmed defrost cycles can be skipped.
The result of this calculation is displayed under
parameter „n/o defr ignored“ (defrost page).
Defrost start will be initiated by the internal clock
or a digital (OC)-input.
A manually initiated defrost cycle resets the 'skip'
memory and starts a new calculation.
Defrost Demand by Differential Method
This defrost method uses two (2) additional
sensors which sense the differential temperature
across the evaporator. This difference increases
with more icing.
At a preset amount of icing (temperature differen-
tial) which is set by parameter „demand defr diff“
(defrost page), the controller starts a measuring
cycle for a certain amount of time which is set by
parameter „dem defr period“.
If, during this period, the differential reading
keeps its value above setting, the controller
stores the need of defrost (displayed by „dem
defr stored“).
Any stored defrost demand results in initiating a
defrost cycle at the next available defrost time
(timer) or upon activating the defrost signal input.
For achieving good results with this demand de-
frost method, the two additional sensors must be
placed carefully as explained in drawing.

Intelligent Defrost (adaptive defrost) for walk-ins (TKP/TKC x140 only)
Main Characteristics
This defrost control method, developed in co-
operation with the ‘GÜNTNER’ company, fits
especially for cold stores and freezers which
areclosed(likewalk-ins),butitislessefficientin
applicationswherethelimitationsensorislocated
in the airflow (e.g. open chest freezers).
This technique reduces significantly the
amount of energy the refrigeration plant
needs.
Especially while difficult situations (like high
air-humidity, in cool-down chambers, while long
opening times of the door of the cold storage
room, uneven feeding of the cold storage room,
etc.)theadaptivemethodprotectstheevaporator
from glaciation safely.
Dynamic ‘room-feeding’ situations engage
the controller to adapt itself to the new
situation, without expensive adjustment by
technical personnel.
Specialized sensors or additional probes
are not required.
Parameterisation is very easy:
• set parameter „defrost mode“ (defrost
page) to „adaptive“
• set parameter „max time to defr“ (defrost
page) to a value which is 2 or 3 times the
normal defrost interval. Within this period
the device decides independently about the
point in time to defrost.
• parameter „time to defr“ (defrost page)
shows the time up to the next defrost.
• parameters „pulse defr limit“ and „defr
temp limit“ define the range within the
heater will be pulsed.
• set parameter „defrost forerun“ to
several minutes, so the fan will be
started before defrost heater starts.
• set parameter „fan off delay“ (setpoint
page) to the time that the fan will continue
running after cut-off of the cooling relay.
Process Sequence
1. In the time period set by „max time to
defr“ the controller decides itself if and at
which moment a defrost cycle is necessary.
If icing is detected, the controller prepares
defrost and begins either immediately or at
the next allowed defrost time.
2. The fan runs while cooling is stopped and
while the defrost heater is not yet switched on
3. The fan stops and the heater starts
4. Each evaporator is individually heated.
The leading evaporator will be recognized
automatically.
5. With working temperatures of [setpoint +
hysteresis >= 2,5°C] the controller is able to
save energy by increases using of the fan
(more circulating air).
6. When the „pulse defrost limit“ is achieved,
the heater will be switched off/on in calculated
periods (optimal heat distribution).
7. Defrost heater cut off, limit temp. is reached.
8. Cooling and fan remain still off (drain time).
9. Cooling starts, fan still off.
10. After end of „fan start delay“ the fan
restarts and normal refrigeration goes on.
Refrigeration
Even during normal operation the fan stays on after
cut-off of cooling to reduce icing.
Recognition of icing
The more ice on the fins the more increases the
difference of temperature between the room sensor
and the evaporator sensor. The controller uses the
value of these sensors, their difference, the historic
curvesof thesevaluesaswell as curvesandduration
of the past defrostings to calculate the necessity of
defrosting.
Use of latent energy by airflow
Werecommendtouse„defrostforerun“(defrostpage)
toswitchonthefanseveralminutesaheadthedefrost
cycle,whilecooling stops and theheaterisnot yet on.
Additionally, the fan is switched on automatically at a
certain difference between the sensors. By this, the
„cooling-energy“ is brought out of the evaporator and
stored in the chamber. This helps also to reduce the
amount of heat energy necessary to defrost.
Defrost start
If all six parameters „defrost time ..“ are set to Off, the
controller decides itself when it starts defrost.
● Further time influence
If you want to prevent that defrost starts at
certain day-times use all the „defrost time..“
parameters and set them to points in time
where defrost is allowed. If no icing is
detected, these times will be ignored.
On the other hand, once icing detected, the
controller will wait for the next „defrost time“
before starting defrost.
● External command
Assign one of the digital inputs to „manual
defrost“. By applying voltage to that input it is
possible to start defrosting at every moment.
Defrost heater
After the end of the "Fan OFF Delay", the defrost
heater switches on up to the temperatur has been
readedthevalue„pulsedefrostlimit“.Theheatenergy
of the heater will dissipate slowly and melt the ice.
The length of the cut-off is calculated by the controller
and as soon as some criteria are fulfilled, it willswitch
on the heater again. The heater will be pulsed until
the temperature of the evaporator sensor reaches
the value of „defrost temp. limit“.
This procedure fits in the same way for the case of
several evaporators in the chamber.
Bythiswayadefrostperiodwilltakelonger,
but will be more efficient.
Special mode for roomtemperatures > 2,5°C
Evaporators can be de-iced already at temperatures
from 2°C by forced air. When cooling stops, fans are
turning on until ice and frost are melted.
Thushumiditystaysinthechamberwhichwillimprove
the quality of certain goods like meat or vegetables.
Additonally to the compulsatory "fan off delay" (fan is
forced to continue turning after cooling reached the
setpoint and stopped), the fan will turn from a specific
temperature[setpoint+hysteresis=> +2,5°C]untilthe
evaporator sensor has reached a certain value.
●Atroomtemperatures[setpoint+hysteresis=>
+2,5°C] notify to set parameter „max time to
defr“ to a higher value, because a defrost start
is forced if this time is past.
Several evaporators in one chamber
For certain plants it is necessary to use several
evaporators in one chamber. The controller is able
to control up to 4 evaporators in one chamber. Even
in this case one unique roomsensor is sufficient.
E.g. for a chamber with 3 evaporators you need
only 4 sensors:
● onecontrolsensor
●threedefrostsensors(oneforeachevaporator)
If a defrost cycle is necessary, all evaporators will
start defrost at the same time to avoid short circuit
of air, when one is heating and the fan of the other
is turning. So the one with the highest rate of icing
determines the start of the defrost cycle.
The controller is able to determine just this evapo-
rator and even to adapt it when conditions change.
Thusalwaystheevaporatorwiththemostice initiates
defrost start, nevertheless the quantity of energy
which is necessary to defrost will be calculated for
each evaporator separately.
To finish defrost cycle all evaporators must have
reached the defrost limitation temperature.
Emergency operation in case of bad conditions
In case recognizing extreme conditions, e.g.:
● chargeofunusualveryhumidgoods
● freezerdoorwasopenaverylongtime
● theevaporatorissprinkledwithwater
● sensorbrokenorshortened
the emergency operation starts.
To detect malfunction of the defrost control the unit
uses the increasing of "max. defrost time".
If a defrost cycle is terminated by this time, the con-
troller starts several defrosts with the interval which
corresponds to one quarter (¼) of the time which is
programmed by „max time to defr“.
Therefore be careful in choosing the time for
this parameter.
After the end of the disturbance the controller works
on normally.
Example
Max time to defrost is set to 24 hours. If defrost
is not terminated by the evaporator sensor, the
controller will start defrost cycle every 24 / 4 = 6
hours until a cycle will be finished by the
evaporator sensor and not by timer.
Independent from this procedure, a failure
message will be initiated.
End of defrost
When the defrost sensor has reached the defrost
limitation temperature, the heater stops and the con-
troller waits until "pause after defrost" has expired, to
allow the melted water to flow to the drainage. Then
cooling starts now, but the fans still stay OFF until the
"fan start delay" has expired to allow the evaporator
to cool down and to prevent that the fans blow warm
and humid air or water drops into the chamber.
Technical Manual Cold Storage Controllers TKP / TKC x130 - x140Page 14
For one or all of the 4circuits it is possible to assign a
relay for the evaporator fan. The fan control depends
on the following parameters:
●„cooling mode“ (mode page)
The fan is controlled from the N/O-contact in
refrigeration mode and from the N/C-contact in
freezing mode.
●„fan operation“ (mode page)
You can select either „permanent“, where the
fan runs continously and stops only during
electric defrost, or select „interval“, where the
fan runs during cooling periods only.
●„defrost type“ (defrost page)
If „on“: fan turns during defrost
If „off“: fan ist stopped during defrost.
Fan off delay
To use latency energy of the ice and evaporator
block the fan may run up to 30 minutes after the
cut-off of valve or compressor („fan off delay“, set-
point page).
Fan trailing delay
Thestart-uptimedelayforthefanafterdefrostingisset

(actual page) show the remaining time up to the fans

Evaporator Fan Control
Examples for fan operation modes
1. fan in permanent mode
This mode is mainly used with refrigerated
shelfs, refrigerated display counters and
chest freezers, where the fan runs even
during defrost. It is not necessary to connect
the fans to a relay of the controller, fans run
directly from mains voltage.
"fan operation" is set to 'permanent', "defrost
type" is set to 'on' and "pause aft. defr" is set
to '0'.
2. fan in interval mode, defrost by fan
In use for cold storage chambers with higher
temperatures. Use a relay output for the fan.
In this case you select „fan operation“= 'inter-
val' and „defrost type“='on'.
3. fan in interval mode, defrost by
electric heater/hot gaz:
In use for cold storage chambers with lower
temperatures and freezers. Use a relay
output for the fan. In this case you select „fan
operation“='interval' and „defrost type“='off'.
The fan runs when cooling is on. The fan is
disabled during defrost periods and comes
on after defrost with a time delay which is set
by the „fan start delay“ parameter.
4. fan in permanent mode and
defrost by electric heater
Use a relay output for the fan. In this case
you select „fan operation“='permanent' and
„defrost type“='off'. Then the fan will run
continously and stops during a defrost period
only. The fan comes on after defrost with a
time delay which is set by the „fan start delay“
parameter.
Please note that the fan relay contacts change with
the application (refrigeration/freezing).

Roller Blind control
Selectingthe„rollerblind“functionontheassignment
page activates the relay output for opening and
closing the roller blind(s) automatically. A defrost
overrides this function and opens the roller blind(s)
for the defrost period.
Internal control
●Therefore don’t use a digital input assigned
with the function „night settings“ or the digital
input must be connected to mains voltage
(= day operation).
The timer parameters „night setp ON“ and
„night setp OFF“ (mode page) are activating
not only the secondary setpoint(s) but have
also an effect on the roller blind.
The ON setting activates the roller blind relay
and runs the roller blind in closed position via
N/O-contact. The OFF setting time deactivates
the relay thus opening the roller blind again.
External control
●Therefore use a digital input and assign it to the
function „night settings“. If the digital input is
connected to mains voltage (phase), the unit
works in day-mode.
This results in de-energizing the relay when
„roller blind“ is selected and running the blind(s)
open via the N/C-contact.
An open input means night-mode and runs the
roller blind(s) shut via the N/O-contact.

Frame Heater control

freezing onto the door frame. In addition it prevents
condensing water around the door or on top of the
frames of open chest freezers.
If one of the relays is assigned to „frame heater“
this will control the energy to the frame heater with
a certain frequency and pulse-width. For day and
night operation you can choose different values to
save energy. The corresponding parameters on the
mode page are:
●„frame period“:
defines the duration of the cycle,
●„frame pulse day“ defines the percentage of
heating during day operation within each cycle.
100% = continuous heating, 0% = off
●„frame pulse night“ defines the percentage of
heating during night operation within each
cycle.
100% = continuous heating, 0% = off
●„frame pulse act“ shows the current active
frame period (which can be shifted by a VPR
host system)
Energy Optimization
Tooptimizethe demandforenergy of the attached
heaters, the controller adapts (within specified
limts) the frequency ratio to the air humidity (e.g.
in a market). The information about the market
temperature and the air humidity is delivered from
a host system (VPR 52xx), to allow the controller
to calculate the absolute humidity.
Limits - Temperature .....19-24°C
- Humidity ...........40-70% r.H.
At the upper limits, the frequency ratio is equiva-
lent to the values set by „frame period“ and „frame
pulse....", at the lower limit the pulse width will be
reduced by half.

Adding controller units to extend
cold storages
If one controller unit has not enough ressources
to control a cold storage, you can add one or
more units. The necessary communication is
made by the digital inputs (This function is only
possible with control circuit 1).
Any digital inputs can be assigned to the follo-
wing functions:
Refrigeration Lock
Refrigeration Lock (active low):
Cooling function of the unit is disabled if no
voltage is present at the digital input.
Refrigeration Lock (active high):
Cooling function of the unit is disabled if the
digital input is connected to mains phase.
If the refrigeration is locked, at the same
time an overtemperature alarm is disabled
for 4 hours.
Forced(/-Released) Refrigeration
Forced(/-Released) Refrigeration (active low):
Cooling function of the controller is released
if no voltage is present at the digital input.
Forced(/-Released) Refrigeration (active high):
Cooling function of the controller is released
if the digital input is connected to mains
phase.
If no control sensor is selected at a slave
module, the refrigeration always switches
with the digital input.
If a control sensor is connected and
selected, the digital input only releases the
refrigeration function and the measured
values are used to control.
Principle of adding controller units
The leading unit releases the cooling function of the 'slave'-units via their digital input 'Forced(/-Released) Refrigeration'. The 'slave'-units disable
the cooling function of the 'master'-unit via its digital input 'Refrigeration Lock', as long as a defrost function works.

Caution
Communication with VPR systems
The TKx controller can be used as intelligent
cold storage controller in co-operation with the
compound control system VPR. In this case, it is
controlledbytheVPR.SotheTKxneedanindividual
address („adress in netwk“, mode page)
Each controller can be assigned to a certain
compound (Refrigeration or Freezing, „com-
pound“, mode page). This enables the VPR to
transmit specific information to the cold storage
controllers assigned to the compound while a
failure occurs.
More detailed information you will find in the tech-
nical manual of the VPR compound system.
Behavior in case of the VPR-function 'Low Power
Optimization'
If this feature is used in the VPR-system, the VPR
can disable the refrigeration functions of the TKx
for a certain time, even though the refrigeration
setpoint is increased. The fans and the heating
continues working, they will be disabled in case
of compound failure only.
All TKx controllers can be networked together
with other ELREHA-control devices. For this duty
ELREHA has developed E-LINK, a transmission
protocol, which will be transmitted on a two-wire
bus-system based on the RS-485-Standard.
With E-LINK, up to 78 controllers are able to
communicate.
Each controller in a network has its individual
address („adress in netwk“, mode page). This
adressisnecessaryfor selectingtherightcontroller
while a data package is transmitted on the network
bus. If the controllers are used outside a network,
the address and the parameter „compound“ are
of no importance.
Never use address 64 !!
Remote control with SMZ
The TKx can be remote controlled by a SMZ
frontend. In this case all display information and
keypresses will be transmitted.
Configuration / Service via PC
The controllers can be linked via RS 232 or RS
485 interface to a PC where a matching the EL-
REHA-software runs. From there you can change
parameters,savethemtotheharddisk(download)
and send it to other controllers (upload).
Networking by RS-485-Bus (E-LINK-Protocol)
Behavior in case of compound failure
If a TKx is assigned to a certain compound and a
disturbance occurs, the unit responds as follows:
●The solenoid valves will be closed
●The fan switches off
●A defrost cycle will be terminated.
A new defrost cycle is only possible when the
compound problem is solved.
To see if this function is released, look
at „solenoid valve“ (actual values page).
Data transmission disturbances
If the controller gets no new information from
the VPR, it continues working with the actual
settings.
If there was an order from the VPR to close the
solenoidvalvesandatechnicaldefectinteruptsthe
datatransmissionformorethan30minutes,theTKx
ignores this order and starts working normally.
When data transmission is restored, the TKx will
workagainimmediatelyaccordingtothecommands
of the VPR.
Wiring of data lines
The Line-Interface resp. Line-Bus (RS-485) allows
to connect the controller to a central unit.
Configuration:
●Use standard "twisted pair" data cable
●Each module/controller gets an individual
address
●The best signal-to-noise ratio you get when
each PE connector is grounded the shortest
way
●The unshielded part of the data cable must be
as short as possible.
The controllers of the TKP 31xx series (from
Soft.Vers. 4.03) are prepared for connecting the
series TAA xx15 Remote Displays.
These displays are able to display the values of
all 6 connectable sensors alternatively.
The TAA display must be connected to the RS-
485-interface "intercom".
Up to 6 TAA xx15 can be connected, each TAA
is able to display any sensor value.
Power Supply
The TAA can be supplied by the TKP-controller
or by an external transformer.
The controllers of the series TKP are
able to supply 2 TAARemote Displays
max.!
Parameterizing
The TKP controller needs no special settings.
At the TAA the # of the sensor to display must
be set by an incremental switch at the rear side
of the housing.
Display while a defrost cycle
If the controller works in a defrost cycle, the
TAA Remote Display holds the last temperature
value, measured at the beginning of the defrost.
After termination of the defrost event, a real
temperature value will be displayed after the
following preconditions:
●The measured actual value is less than the
displayed value + 2K
●After the alarm delay extension is run down
For further information please read the manual
of the used TAA Remote Display.

Installation / Start-Up
A few seconds after power-up the display shows type, date and time or the
parameter selected as permanent display. Any key turns the backlight on.
If the device is switched on the first time, you are now invited to change or
confirm the language.
Start-up course
● checkand/orsettheactualtimeanddateofthecontroller
●determinethefunctionofallinputsandoutputsontheassignmentpage.
(only possible in the 'configuration level', which is the factory setting.
See also page 3). Unless you haven’t done this, you will not see all
necessary parameters on the other pages!
● selecttypeofusedtemperaturesensors(„sensor“, mode page).
●correctthedisplayedtemperaturevaluesifnecessary
(„corr sensor..“, mode page).
●selectthedesired„defrost mode“ (defrost page) and select if the fan
should turn during defrost or not.
●selectcoolingmodeonmodepage
(note: will influence the electrical connection of the relay.)
These are the most important steps for a basic configuration. Upon that, adapt
the other parameters like temperature setpoint, hysteresis, delay times....
Refer to the previous chapters in this manual.
Start-up in a data network
● settheaddressofthecontroller(modepage)
●verifythebaudrate(modepage)
●LoadtheparametersfromthePCtothecontroller(upload).
Start-up with a PC/Laptop
The start-up of the controller can be much easier by using a PC and the
software "COOLVision-MES". In this case the controller will be connected
via the RS-232 interface.
● settheadressofthecontroller(modepage)
●operatetheunitfromthePCremotely
The controller gives you an overview about the controlled unit on the "Actual
Values" page:
· temperatures (all sensors) · remaining delay times
· analog value · state of the digital inputs
· state of the relais · actual and historic failures
If failures are present, they are listed on the "act.failure page"
Sensor Positions
The controller needs correct tempera-
ture input information to work correctly,
but in standard applications, sensor
positions are not critical.
The control sensor for regulation or
alarm sensor has to be fixed behind
the evaporator (air inlet) or at a repre-
sentative place in the chamber, but not
in the air outlet.
The second sensor (defrost sensor
or evaporator sensor) should be
assembled in the tube which is factory
provided for this purpose. If the evapo-
rator has not such a tube, assemble it
between the fins in the upper part and
assure a good thermal exchange. It
should be placed at the position where
the icing stays the longest time while
defrosting. This depends of type and
manufacturer of the evaporator, so use
your experience.
Makesurethatthesensordoesn’ttouch
the heater or any piping with hot gas defrost, it must have some distance to
these heat sources. We indicate that remaining ice in an evaporator even after
a defrost period is due to sensors which have not enough thermal contact or
which are installed at a wrong place. If you encount icing you should place
the defrost sensor to this area.
Demand Defrost Method (TKP x140 only)
To detect icing with the Demand Defrost Method the TKP x140 does not need
additional sensors. The control sensor and the defrost sensor are sufficient.
Please note that the emergency defrost operation of this method cannot avoid
a slow icing of the evaporator as a result of a wrong sensor position. In case
of ice headings, the evaporator sensor must be replaced (after complete
melting) to that position.
Basic Configuration of TKP 3130/1
Because the TKP 3130/1 has no own operating elements and no display, the
basic configuration must be done in a special way.
●Note: The network adress of the cntroller unit ("adress in netwk",
Mode Page) is factory set to '78'.
●Prepare VPR-System
●Connect a single TKP 3130/1 to the RS-485-Line interface.
Also multiple controller units can be connected to the line-interface, but
it makes sense that only one of this owns the adress '78', because the
configuration function transmits the new data only to units with the
factory set adress '78'. Connecting multiple new TKP 3130/1 at the same
time doesn't work.
● Opensubpage"ServiceData"attheVPR-Display.
● SetdesirednetworkadressfortheTKPatparameter
"Change CST adress".
●The new adress will be transmitted to the TKP.
●As usual, the TKP can be inserted and programmed on the
CST-pages of the VPR-System.
●Connect next controller to the interface and repeat procedure.
With this controller type, only sensors of the TF 501 series
(Pt1000) can be used.
