Spare Parts

The memory module is available as a spare part for all the Push Button Panel
unit versions.
All the parameters concerning the interface to the PLC are stored in the Push
Button Panel memory module. In cases where the unit electronics or the entire
unit are replaced, the interface need not be reconfigured. Only the old memory
module needs to be transferred to the new unit.
If the Push Button Panel memory module is defect, the message EEPROM
ERR appears in the display in both normal operation and hardware test mode.
In this case, the memory module must be replaced.
The following spare parts are only available for the PP17-I unit:
It is not necessary to remove the Push Button Panel from the cabinet in order to
install the spare parts. Even the 22.5 mm elements, individually installed and
connected by the customer, can remain in position.
