Error Messages / Error Memory / Error Codes
If a failure occurs, parameter
L20
will display a flashing error code, (see below Error Code Definition
List for reference). If multiple errors occur, the UP/DOWN arrow keys can be used to scroll through the
error codes on the device display. The device is designed to always store the last
15
error messages,
(including date and time of each occurrence), and can be accessed via data interface.

Temperature Sensors
These types of temperature sensors can be used:
-
TF 201
, PTC sensor (2000 ohms@25°C)
-
TF 501
, PT1000 sensor (1000 ohms@0°C)
- customer specific sensor
So1
(-40...+25°C)
- customer specific sensor
So2
(-50...+50°C)
The type of sensor can be set by '
h20
' (Assignment
Page).
Pressure Transmitter
Pressure Transmitters with 4...20mA output can
be used.
They must be selected with the parameters "
h25-
h26
" (Assignment Page).
'Default Display Parameter' - Function
When the device is powered up, the "Default Display
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.
They can be used for any function within
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.
