Replacing Data Acquisition Modules of Different Types

If a parameterized data acquisition module is to be replaced by a module of a different type, care
must be taken that this module is deleted in the system parameters before being physically
replaced. If an acquisition module is replaced by a module of the same type, the individual
parameterization steps can be omitted.
Proceed as follows to replace the module:
1. Switch the SIMEAS R-PMU on using switch S1.
2. Connect a notebook to the service interface COM S at the front of the device.
3. Use the OSCOP P system program to remove the acquisition module to be replaced from
the system parameters. That means that you remove all channel assignments that might be
provided for this module and parameterize the slot as Deactivated. For detailed information
regarding the parameterization, please refer to Chapter 12.
4. Disconnect the notebook from the service interface COM S.
5. Switch the SIMEAS R-PMU off using switch S1.
6. De-energize the device.
7. Unscrew the cover.
8. Unscrew the knurled nut from switch S1.
9. Unscrew the front plate. Only loosen the lower screws and totally remove the top screws.
10. Remove the connecting line (ribbon cable) between the front plate and the CPU module at
the CPU module.
11. Carefully remove the bus board from the plug-in modules. Make sure you do not bend the
bus board.
12. Pull the acquisition module to be removed out of the device from the front.
13. Remove the signal lines and the dummy plates from the slot where the new acquisition
module is to be plugged in at the rear panel.
14. Once you have removed the old adapters, screw on the appropriate adapter for the new
module at the rear panel.
15. Now insert the new module from the front side into the free slot. Make sure the module is
properly engaged.
WARNING
Warning about deformed or damaged EMC springs.
Nonobservance of the safety instructions means that death, heavy
injuries or considerable material damages can occur.
•
Before inserting a new module, check the EMC springs on the rear side. EMC springs must
not be deformed or damaged.
•
Deformed or damaged EMC springs have to be replaced.
•
Take care that the EMC springs do not get stuck at the vertical covers between the slots while
inserting the module to avoid deformations or damage.
16. Carefully reattach the bus board to the individual modules. Make sure you do not bend the
bus board.
