Replacing the central module
Generally, when a central module has been replaced, all data which can be changed are
set to the factory setting.
Proceed as described below if a central module is replaced:
1. If possible, note the customized settings of the device, such as:
– Calibration data
– Current assignment, main parameter and temperature
– Relay function selections
– Limit value/controller settings
– Cleaning settings
– Monitoring functions
– Interface parameters
2. Disassemble the device as explained in the "Dismantling the panel-mounted instrument"
or "Dismantling the field instrument" section.
3. Use the part number on the central module to check whether the new module has the
same part number as the previous module.
4. Assemble the device with the new module.
5. Start up the device again and check the basic functions (e.g. measured value and
temperature display, operation via keyboard).
6. Enter the serial number:
– Read the serial number (“ser-no.”) on the nameplate of the device.
– Enter this number in the fields E115 (year, one-digit), E116 (month, one-digit), E117
(consecutive number, four-digit).
– In the field E118, the complete number is displayed again so you can check it is
correct.
You can only enter the serial number for new modules with the serial number
0000. This can only be done
once
! For this reason, make sure the number
entered is correct before you confirm with ENTER!
Entry of an incorrect code will prevent the additional functions from being
enabled. An incorrect serial number can only be corrected at the factory!
Press ENTER to confirm the serial number or cancel the entry to enter the number
again.
7. If available, enter the release codes for the Plus Package and/or Chemoclean in the
"Service" menu.
8. Check the Plus Package release (e.g. by opening the function group CHECK / Code P) or
the Chemoclean function.
9. Make the customer device settings again.
