Replace and Return Defective Device
Error Backup Module
If you cannot correct a defect reported by the device, you can replace this device with a backup device.
The backup device is configured with available project data from Reydisp Manager 2. Once the device has
failed in this manner, it is non-recoverable at site and must be returned to the manufacturer for repair.
The relay should be returned as a complete unit. No attempt should be made to disassemble the unit to isolate
and return only the damaged sub-assembly. It may however be convenient to fit the withdrawable relay to the
outer case from a spare relay, to avoid the disturbance of relay panel wiring, for return to local Siemens office.
The withdrawable relay should never be transported without the protection of the outer case.
Replacing a Device
The following shows the steps that should be taken to replace a device:
•
Take the device out of operation
•
Remove the wired terminal blocks from the module to be exchanged or alternatively all lines from the
device
•
Remove the device and fitting parts
•
If needed, assemble the replacement base module with the expansion modules
•
Put the device back into operation (see 7 In Service Operation ).
Returning a Device
The following steps should be taken when returning a device:
•
Ensure that the devices are either shipped with the original case – if the case is to remain in the system –
or with the designated transport safety devices
•
Protect the optical interfaces on the communication or arc-protection modules against the ingress of
dust. Use, for example, the protective caps provided in the delivery condition.
•
Pack the defective device (base module and expansion module) or the complete device (see
1.1 Unpacking, Repacking, Returning, and Storing )
•
Return the defective device to your Siemens local office or sales partner
