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

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
MON.........mains supply switched on
SiCh ........security chain open
SBr X ......sensor X broken
SSH X .....sensor X short
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.

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
(calls up Configuration Level)
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.
● Selectionofa"virtualsensor":
- Assignment of a function by "funct sens7a-c"
● Selectionofa'physical'sensorwhichmusthave

- Activating of the sensor by assigning a

● Setweightingfortheselectedsensor
(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).

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
iscancelledautomatically

Overtemperature Alarm
Itispossibletoselectmax.4alarmsensorsforacircuit
(e.g. 4x "alarm sensor 1"). If the temperature at any
of the alarm sensors gets higher than the effective
setpoint plus the „warning offset“ setting, an alarm
will be initiated after the delay time.
Low temperature Alarm

„warn low limit“ setting works as a threshold for the
"Low temperature Limitation" function at the same
time. Low temperature alarm can be disabled by
"alm temp low" (mode page).
Supplementary warning delay during defrost

to stabilize and the normal warning delay turns out to
be too short. For this reason the „defrost alarm delay“
(defrost page) setting adds on to the normal warning
delay after defrost.

Emergency Operation
If all control sensors fail, the unit turns to an
emergency mode automatically. The cooling relay
cycles with a %-part ("emergency operat.", Mode
Page) of the 30 minutes period.

Exception: If no alarm sensor is as-

cooling continues without interruption. The
cooling remains active and the fan starts
again, so the door opening is ignored.
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
actHigh“ and is connected to phase, all control func-
tionsaredisabled.Thedisplaycontinuesworking,but
noalarmwillbeactivated.Thisismemorizedinthelist
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.
