3.2 Service-relevant modules
As is apparent from the previous list of components, not all the modules in the SCP System can be
repaired individually on site. Please consider the following before starting to service the system:
Pump control panel
On-site repairs can be performed by replacing boards or individual modules (e.g. shaft angle encoder,
connecting cable). Service work on the boards themselves is not performed on site. The only exception
to this is the replacement of the EPROM with the firmware necessary for operation (update).
Drive unit
Adjustment of the mechanical components requires precision tools and test instruments that are not
available to the on-site service team. The following errors therefore cannot be eliminated directly and
require the replacement of the whole drive unit:
◗ Defective motor
◗ Defective Hall sensor
◗ Mechanical errors (e.g. warehouse damage, unusual operating noises)
Emergency drive unit
The same restrictions apply to the emergency drive unit as to the drive unit; mechanical repairs and
adjustment operations are not possible on site. The board for the speed display is only accessible after
the drive unit mechanism has been partially disassembled, so that in this case also it is not possible to
replace the board. Always therefore replace a defective emergency drive unit completely.
Flow sensor
The sensor does not contain any components that can be repaired and that are accessible for
servicing. Always therefore replace a defective flow sensor completely.
