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.

When connecting the switch
outputs, the overvoltage
category must be respected !
*When connecting an
inductiveload,suchasrelay,
to the Solid State Relay
output, it may be necessary
to connect a snubber circuit
in parallel to the
load to protect
the output from
engaging
unexpectedly.
The snubber
circuit must be
properlyadapted
totheloadinordertopreventtheoutput
from engaging permanently.

values to occur.
• 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 to the
device when operated if the aforementioned conditions
are not within the device specifications.
Examples:
- Supply voltage (printed on the type label).
- Environmental limits for temperature/humidity.
- Maximum current rating for the relays.
• Sensor/probe cables must be shielded. Don’t install them
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.
• Note related to wire lenghts connected to the device:
Wire should be 0,5mm² at a minimum.
• Mounting the device in close proximity to power relays
is NOT recommended. Strong electro-magnetic
interference may cause the device to malfunction!
• All line interface wiring must meet the specified
requirements.
• All temperature sensors connected to the device must be
