Pressure Transmitters with 4...20mA output can
be used.
They must be selected with the parameters "h25-
h26" (Assignment Page).
'Default Display Parameter' - Function
Whenthedeviceispowered up,the"DefaultDisplay
Parameter" will appear on the display after a few
seconds. (This will also be displayed during normal
operation of the system or if no key is pressed for
at least 3 minutes)
"L10": Actual Value is factory preset and can be
changed at any time.
Note: In the event of a failure, 1st Priority will be to
display the current failure.
Configuration Concept
The inputs/outputs of the MSR eco Stage Controller
have no fixed functions.The MSR eco works with an
"open configuration" concept. This means that all
available inputs and outputs (relays, sensors, digital
inputs, analogue output) can be configured to work
with any available control function or control circuit.
Temperature Sensors
Sensors can be used to control, or simply to
display.
Digital inputs (DI, Optocoupler inputs)
Each digital input can be assigned to one of the
possible functions.
Relay Outputs
Each relay can be used to control one of the possible
functions and can also be switched on manually.
The relay outputs #2, #3 and #5 are Solid
State Relays (SSR) with a lower contact
rating than the standard relay outputs.
Theycanbeused foranyfunctionwithin
the specified current range.
Parameter
Only assigned parameters will appear on the
parameter page for scrolling efficiency.
Assignment
The function of each input and output can be preset
on the 'assignment page'. The assignment can be
done by keys or via interface.
Notice
Change permanent parameter
- Select the parameter you want to have as
"default display parameter"
- Press "" and "" simultaneously.
The display shows "888" for a moment, after
that the selected parameter will be shown as
the 'default display parameter'.

Configuration parameter sets
The MSR eco includes two predefined configura-
tions, which can be loaded. Overmore the user can
save and recall another individual set of configurati-
on parameters, the ‚user defined configuration‘.
It is only available if it was saved before by ‚h90‘
(Assignment Page), which saves all current settings
to the ‚user defined configuration‘.
To do this, the OEM-Code is necessary.
Sequence:
- Select 'h90'
- Press the P-key
- '---' appears
- Press the UP-key and enter the OEM-code
- Select 'do' with the UP-key
- Save the parameter by clicking the P-key
- 'don' for action executed respective 'Err' for action
not executed will be displayed for about 2 seconds.
If an overwrite of the existing configuration is not
desired, then the operation can be aborted before
pressing the „P“ key. When the display shows
„do“, press the „Down“ key again and „---“ will be
shown on the display. Now press the „P“ key.
„h90“ will appear on the display.
In order to restore a saved user configuration, this
can be achieved by selecting „h91“ and entering
code „70“. „h91“ can also be used to load the
values from the „permanent preset configuration“.
If no configuration was previously saved, then
„h91“ cannot be selected.
Behaviour of the User Configurations at Program
Updates:
After updates, if an OEM configuration is available,
it is possible to load all parameters which are stored
in the respective program version.
New parameters will be set to default values.
With program downgrades / updates in
in combination with OEM configurations
saving/loading, parameters in the user
configuration may be lost.

Access Levels
Notallparametersarevisibleontheuserinterface.Dependingontheoperator‘s
authorization, parameters are switched on or off.
Three Access Levels are available:
Level 1 - only selected parameters - for the customer (default display)
Level 2 - parameter for the technician (P99 = 88)
Level 3 - all parameters (P99 = 70)
To enter the access authorization, there is parameter P99 in the mode list.
If the value 88 is entered for this parameter, all parameters of level 2 are
displayed.
When the value 70 is entered, all parameters of level 3 are displayed.
If the controller is not operated for 3 minutes, the display returns to the
basic display and only the parameters of level 1 are accessible.
Only required parameters are accessable on the display, depending on
the current configuration.
With parameter h91, code 70 can be used to load one of four fixed configu-
rations or a stored configuration. For special protection, the code number
70 must be entered each time for this parameter.
Selection options: „cF1“, „cF2“, „cF3“, „cF4“, „cFU“ and „---“ for termination.
The values of the four fixed configurations can be seen in the parameter
list.

Functional Description
Input Signals of the Controller
The input signals come from a 2-wire pressure
transmitter with a 4-20 mA signal or one of the four
(4) temperatureprobes.The sourcecanbeselected
at h21...h26 (Assignment page).
If a pressure transmitter is selected, additionally
a refrigerant must be defined (at h99), which is
necessary to calculate a temperature in °C.
Calibration of Transmitter, Display Correction
For each transmitter input must be defined, which
pressure corresponds to the delivered 4-20 mA
signals.
4-20mA Input
For this inputs, the matching pressure limits can
be set by h93, h94 (pressure transmitter input 1)
and h95, h96 (pressure transmitter input 2).
Probe-/Transmitter Failures
Ifaprobeor transmitterfailureisidentified, all stages
will switch ON with the selected delay.
After the alarm delay r08, the alarm relay (ALA)
switches off if it is defined and available.
Control of Compressors (Load)
TheMSR
ecoisabletocontrolupto8 (withextension
module BMR 3002) single or multi-stage loads with
up to four stages.
The kind and number of stages of the selected
loads must be defined with the parameters h51 up
to h58. Example:
Standard Stage Controller
Applications include:
- Standard compressors
- Compressors with
CRII Control Stages / Power Control
- Condensation High Pressure Control
Standard Compressors (SP)
The control setpoint is preset by r01 (day) or r02
(night). With r03 a maximum value for this setpoint
can be determined.The range of the hysteresis can
be set using parameter r04, while r05 determines
the position above the set point, (above, below, or
balanced).
Forerun (Stages ON)
If the actual value exceeds the switching point,
then the forerun delay starts (r41...r48, individual
for each stage). After this timer is run down, a stage
will be switched ON and the individual delay time
starts again.
Neutral Zone
If the actual value is located within the hysteresis
range r04/r05, no stage will be activated or
de-activated.
Backrun (Stages will switch OFF)
If the actual value falls below the tripping point,
the backrun delay (r51...r58, individual for each
stage) will be started. After this timer is run down,
one stage will switch OFF and the individual delay
time starts again.
L21 shows the current state of the
controller.
Limits
If the actual measured value falls to a critical
level, the controller will react in two ways:
If the actual value falls below the Early Warning
Alarm setpoint, parameter ‚r07‘, then at least 50%
of the motors will switch off, once the set time of
parameter ‚r08‘ is reached.
If the actual value falls below parameter ‚r06‘,
then a forced Backrun will also be initiated,
shutting down all motors.

Base Load Change / Switching Frequency Opt.
If a plant is laid out correctly, then not all fans and
compressors should run continuously. When
using normal stage controllers, some motors bear
a heavy load while other hardly any load at all. To
prevent this, the „Base Load Change“ function can
be utilized. (This function is also known as Stage
Sequencing).
The „r22“ parameter monitors the relative run
times of the motors and will establish a consistent
balance of approximately the same runtime for
each motor. Different application scenarios can be
selected. If a multistage unit is being used, only
the runtime of the leading stage, (=motor on) will
be calculated.
The control system records and stores the runtime
and downtime of each motor to determine which
motor can be switched on or off.
During „Backrun“ operation, the motor with the
longest run time will be switched off first. For the
„Forerun“ operation, the option exists to select the
motor based on (a) shortest runtime, or (b) longest
downtime.
If the pressure ratio in the plant does not change
over a long period of time, no 'Forerun/Backrun' is
active and a sequencing is impossible. The 'Delay
Time (r20) starts a short backrun after the set time
to enable a new motor selection.
It is also possible to select an optimization function,
(c), for the switching frequency. If the optimization
function is activated, during backrun, the controller
switches off an additional stage on a compressor
before a motor is switched off.
Thus, a more uniform utilization can be
achieved without any particular motor car-
rying an unnecessary higher load.
With r21 an Operational-Feedback Time can be
set, which determines when a feedback signal
must be recognized.
Minimum Idle Time
If a motor is switched off, it can be restarted after a
Minimum Idle Time (r71...r78).
Control of Compressors with
CRII-System Power Control
This control method can be activated by the pa-
rameter "h49". With this method, only one of the
compressors can be controlled.
Characteristicforthiscompressortypeisthefactthat
the first stage generates no refrigeration capacity.
The control of the refrigeration capacity is achieved
by a fast on/off switching of the power stages.
Control
The control of the CRII-Valves is always inverted,
that means if voltage appears at the corresponding
output, the respective power stage is deactivated.
The switching behaviour must be set separately
for each power stage (inverted for CRII-power
stages, h61...h68).
While a standstill, the CRII-Valves of the motor will
be de-energized. With the start of the motor the
switching outputs of the power stages will be
utlized at the same time.
If the motor runs without power stages, an
adjustable „switch-off“ countdown "r24" will be
initiated. Once the set amount of time is depleted,
the motor will be switched off.
The controller performs regular sequence
exchanges to ensure the CRII Valves switch an
equal number of times.
The forerun/backrun behaviour is the same as at
the standard application.
Toggling of Power Stages
If the power requirement develops in the way that
a power stage switches repeatedly, the forerun/
backrun delay times are not used, but the
respective stage can be switched on/off
immediately after "r23“ (Idle Time of the stage with
0% load).
Base Load Change with Switching Frequency
Optimization at Backrun
Due to the special requirements of the control de-
pending on the basic stage, the Switching
Frequency Optimization does not work and must
be de-activated. So only the values "000, rr0, hr0“
are allowed for the parameter "r22“.
"rr1" and "hr1" are treated as "rr0" and "hr0"
respectively.
Condensation High Pressure Control (HP)
The Condensation High Pressure Control can
be used with the analogue output as P-controller
and/or with up to 8 relay stages. The relay stages
can be assigned to up to 8 machines. For each
stage a forerun delay time (d41...d48), a backrun
delay time (d51...d58) and a setpoint (d01...d08)
is available. Each motor can be set to manually/off/
automatic (d61...d68) as well as a minimum idle
time (d71...d78).
The HP function has the same base-load change
function and switching optimization as the SP
function. HP operates with an unified control
hysteresis (d12) and hysteresis position (d13),
relative to the active setpoint.
Depending in the number of stages that are on, the
On/Off Switch position will be depended on the
respective setpoint - hysteresis respectively the
next setpoint + hysteresis. With it, the position of
the hysteresis is taken into account. When using
the analogue output P Controller, the proportional
range is determined by the switch-on/off positions
of the respective stage, depending on the number
of running stages. If the configuration has only one
or zero stages, the switch-on/off positions are
represented by the first setpoint and the hysteresis
of the stage controller only.
Two (2) limit values 'High pressure alarm limit'
(d17) and 'High pressure pre alarm limit' (d18)
generate error messages when exceeded.
If d18 is exceeded, a load limitation of the SP
machines will be activated to max 75% of the
selected machines. If d17 is exceeded, all SP
motors will be switched off by fast backrun.
Minimum Overheat Monitoring (SP)
In order to avoid insufficient overheat, and the po-
tential for liquid refrigerant to flow into the suction
tube, in systems where there may not be enough
compressor power to create sufficient overheat,
the „Minimum Superheat Threshold“, parameter
‚P10‘ should be used. When the established mini-
mum limit is not reached, an alarm will be triggered
and the expansion valves of the cooling positions
will be locked with special settings.
An additional temperature probe (Sut) would need
to be installed at the suction tube. The suction gas
overheat will be calculated using the measured
temperature value at the suction tube and the
suction pressure transmitter.
If ‚P10‘ is not reached, and ‚P12‘, („Superheat
Warning Delay Timer“) times out, then an „SSG
Warning“ alarm will be activated, and if needed,
the cooling positions will be locked.
The backrun of the last running compressor stages
will not be generated at the standard switch point,
but the compound sucks up to the defined suction
pressure pre-warning setpoint, and switches off
without delay.
If the overheat has reached the defined limit value
+ hysteresis, the warnings and cooling position
locks will be canceled.
If the overheat falls below a second limit value
(Compound lock threshold minimal superheat,
P14), which is smaller than the first limit value,
after the settable delay time (P15) a fast backrun
of the compound will be started and an alarm 'SSG
fault' appears.
The delay for the switch-off starts earliest, after
the alarm delay (P12, warn delay superheat) has
been run down. The compound will be released if
the second limit value has been reached again or
exceeded.

SDS -
Suction Pressure Optimization by
Setpoint Shifting with Cold Storage
Controllers
Cold Storage Controllers with EEx-Valves:
When there is a reduced-power requirement, the
setpoint of the compound should be higher than the
set value. If there is a demand for power at a cold
storagelocation,thenitmustensuredthatthesetpoint
shifts down enough to allow the cold storage to reach
its low setpoints.
Within a fixed time interval it will be checked if the
opening rate of the EEx-Valves of the connected
controllers have exceeded a specific limit (r18).
If the limit has been exceeded at least at one
cooling position, then the setpoint of the compound
is reduced by a certain value (r19).
If the actual value of the alarm probe exceeds the
limit at even one of the cold storage locations, the
setpoint must be lowered. The limit value is based
on the switch-ON point + d3.
If the following conditions occur, then the setpoint of
the compound can be raised by a set value, ‚r19‘, up
to to the maximum setpoint defined by ‚r03‘:
1. At least one EEx-Valve of a cold storage location
is below the limit ‚r17‘.
2. No units are running above the upper limit.
3. No cold storage location has exceeded the
safety limit.
Cold Storage Controllers without EEx-Valves:
In these cases, if the actual value of the alarm probe
has exceeded the limit value, (switching point +
d03), a reduction of the suction pressure setpoint
will be needed. If the actual value is equal to or less
than the limit value, the suction pressure setpoint
can be raised.
The setpoint utilized by the compressor control is
based on the adjusted setpoint, ‚r01 or r02‘, and the
offset values, which are generated by the optimi-
zation process. The entered setpoint is the lowest
possible setpoint.
For each connected cold storage controller with
EEx-Valves two parameters are available at which
this influence can be set up:
d02 .....0=off/no effect, 1=Limitation Temperature,
2=Limitation Temperature
+ Opening Degree
d03 ..... Suction Pressure Shift - Temp. Offset
The current increase/decrease values, which have
been produced by this function, can be read at
L31/L32.
SP-Optimized switching by variable Forerun/
Backrun Runtimes (VBR)
If the difference between setpoint and actual value
is small, the number of switching events should
be reduced. Rapid changes in suction pressure
require a quick delivery of power, which requires
a quick reduction in the power reserve.
This can be achieved by variable switching delays
depending on the actual offset from the setpoint.
This function, ‚r40‘, is located on the Setpoint
Page.
The forerun/backrun times will be activated if the
suction pressure goes beyond the hysteresis
range. Above and below the hysteresis range are
definable areas (VBR Forerun Range r41
respective VBR Backrun Range r42). If the
suction pressure actual value moves within this
areas, the forerun/backrun times will be varied
within the ranges set by r43 (VBR Forerun/
Backrun Time min) and r44 (VBR Forerun/
Backrun Time max).
The bigger the difference between actual value
and setpoint, the shorter the time delay. If the
actual value leaves the set range, always the
smallest set delay value will be used.
If the elapsed time increases the current calcula-
ted time, the function begins to switch.
For information L34 (Remaining time of Forerun/
Backrun) shows the current calculated delay
time.

Machines with Feedback (SP, Motor 1-4)
To detect the real state of a machine, the safety chain
can be checked using a digital input, which has a
feedback function, (h31...h34).
The controller switches a machine on and waits for a
feedback signal while power is being applied to the
digital input. If no feedback is detected, the machine
will be switched off and a different machine will be
selected.
‚r21‘ can be used to set the waiting time. If the swit-
ching of a machine is unsuccessful, a new starting
attempt can be initiated after an automatically
calculated time delay.
Switching Behaviour of the Stage Relays
The switching behaviour can be set to active (relay
switches on) or passive (relay switches off) with the
parameters (h61...h68, SP) and (h81...h88, HP).
With the setting '1' the stage will be inverted, with
'0' the stage switches normally.
Load Limitation (SP)
A load limitation can be established for each of the 4
digital inputs. This can be used during peak opera-
tion periods. Two inputs can be assigned their own
maximumnumber(r11...r12) ofrunning machines to
provide more opportunity for energy savings.
Operating Mode of the Motors (Manual/Auto)
Eachmotorcanbesettomanual„ON/OFF“operation
via ‚r61-r68‘ for SP, and ‚d61-d68‘ for HP.
Default „ON/OFF“ operation is set to „Auto“.
Second Setpoint (Ex. Night Operation)
Alternate setpoints can be established for energy
savings. ‚r01‘ can be established as a day setpoint,
and ‚r02‘ for night time. These can be alternated via
internal timer settings ‚P21‘/‘P22‘, or any digital input
‚h31...h34‘, setting dnl or dnh.
If one of the DI inputs is configured for day/night
switching and it has been activated,, the 2nd
setpoint is active all time and cannot be changed
by the internal timer.
If you want to use external switching only, please
set 'P21' and 'P22' to „oFF“.
For night operation, the high pressure controller
has a night offset (d10) and additionally a night
limitation (d11) for the analogue output.

Digital Inputs
With the Digital Inputs DI1...DI4 (for mains voltage)
a number of tasks can be triggered which can be set
on the Assignment Page (h).
If the input is not required, it should be switched off.
Whether the digital input reacts on voltage, (Active),
or on no voltage, (Passive), is dependent upon the
selected task:

Real Time Clock / Time Synchronization /
Night Mode
The built-in real time clock has a buffer for max. 10
days without mains voltage. Date and time can be
set by "P80"..."P85" (Mode Page).
By default, a GMT +01:00 is set (P71 = 60 min.),
which is standard for the Central European Area.
If the product is used in other countries, this value
can be changed.
Summer/Winter Switch - Time Zones
An automatic summer/winter switch "P70 = EU"
(Mode Page) considers the current EU-rules from
1996 (EU 96), but can also be switched off or set
as needed.
Thecurrentsetting,(Summer/Winter),canbeviewed

Control with the Analogue Output
(P-Controller, HP)
To adapt to the process, the following parameters
can be set on the Setpoint Page.
d20 = P Analogue Output - Output Delay
d21 = P Analogue Output - Step Size
Thisfunctioncanbeusedfortriggeringofa frequency

signal will be generated if the analogue output has
reached its maximum value.
Inversely a backrun signal will be generated only, if
the analogue output has fallen to 0%.
By the 'Night Limitation' setpoint (d11) the maximium
value of the analogue output while night operation
can be limited.
Function Control
L96 (Actual Values Page) shows the current output
signal as %-value of the selected range.
Analogue Output
The analogue output can be used for regulation
purposesorforwardingoftheactualvalue.Thesignal
is available as a DC-Voltage (010) or a DC-Current-
Signal (420), set by "h40" (Assignment Page).
Parameter "L96" (Actual Values Page) shows the
current output signal as a %-part of the selected
range. Parameter "h41" (Assignment Page)
determines the behaviour of the output:
Functions
h41 = "- - - " = Output signal fixed to 0V respective. 4mA
h41 = "100" = Output signal fixed to
10V respective 20mA
h41 = "LPI" = Output for PI control SP
h41 = "HP" = Output for P control HP
Control with the Analogue Output
(PI controller, SP)
To adapt to the process, the following parameters
can be set on the Setpoint Page. For working with
extremedeadtimes,thecontrollerallowsanadditional
output delay:
r13 = PI proportional band/range, located
symmetrically around the setpoint
r14 = PI integral time
r15 = PI output delay
r16 = PI step size
If a demand comes from the controller which causes
the analogue output to rise or fall, then an Output
Delay (r15, Setpoint Page) will be started. Within this
time period, the output signal changes only by a set
percentage rate (Step Size, r16).
If "r16" is set to "100%" and "r15" to "0", then the
function is de-activated.
These parameters apply to all PI functions which can
be realized by the analogue output.

The scheme besideshows briefly,howthe dataline
wiring of several controllers via the 'network/line'
interface is made.At each controller, the shield has
to be connected to the nearest ground terminal
(PE). Also the ground connector of the controller
(term.1) and terminal #24 must be connected to
the nearest ground terminal.
This will assure good interference suppression,
even for long datalines between the controllers.
The MSR eco can be used as a Central Unit for
up to 64 Cold Storage Controllers of the series
EVP and TKP. These can be connected via a
separate network interface.
Shieldingmustbeconnectedtothenearestground
terminal.Alsothegroundconnectorofthecontroller
(term.1) and terminal #24 must be connected to
the nearest ground terminal.
Each connected controller gets an individual
address, which must be set at the controller and
on the Address Page (A) under A00...A63.
Thus, data can be centralized and forwarded for
optimization of the control functions.
On the ‚Address Page‘, the controller ‚type‘
must be selected via ‚d01‘ for each address, as
well as the influence on the suction pressure
shifting of the MSR eco via ‚d02 and d03‘ for
each address.
Connection of Cold Storage Controllers as Slaves
Wiring of data lines (Network Line)
Networking of controllers via E-LINK
The MSR eco can be networked together with
other ELREHA control devices via an RS-485-2-
wire databus, which enables up to 78 controllers
to communicate. For communication, the E-LINK
transmission protocol is used.
Each controller in a network has its individual
address ('P90', Mode Page).
!! Never use address 64 !!
The data transmission rate is factory set to "96"
(9600 Baud) and can also be set manually ("P89",
Mode Page).
IftheMSR eco isnotconnected toa network,these
parameters are of no importance.
Remote control at Frontend Systems
The MSR eco controller can be operated remotely
via interface when it is connected to Frontend
Systems such as an SMZ.
Inthiscase,theFrontendSystemshowsthedisplay
contents and the keys of the frontend work as if
they where the keys of the MSR eco .
Configuration / Service via PC
The controller can be linked to a PC via its RS-485
interface. By using the PC-software „Coolvision-
MES“, parameters can be changed, they can be
saved to the hard disk (download) and can be sent
to the controllers (upload).
To do this, the PC must be equipped with an RS-
485 interface (internal card or a converter of the
SSC-series).
