MAINTENANCE SCU
The Starter Control Unit consists of a multi-layer withdrawable main board and fixed mounted interface board.
The interface board contains an EEPROM and the DeviceNet™ connectors. The EEPROM contains all the
SCU-specific motor data. A jumper setting on the main board determines whether the print functions as a
Starter or Feeder Control Unit. The main board and the interface board can be replaced while the system
remains operative.
The Starter Control Unit is maintenanced on print level. A faulty SCU or interface board is replaced by a new
one.

Warning
While replacing an interface board of an SCU the associated feeder can not be controlled via
DeviceNet. Therefore the replacement should always be reported according to local safety
procedures.
Warning
Clink II components contain Electrostatic Discharge sensitive parts and assemblies. Static control
precautions are required when installing, testing, servicing, or repairing an assembly. Component
damage (including degradation or malfunctioning of the performance) may result if ESD control
procedures are not followed.
7.1
Replacement of the main board
1
Before replacement of a main board the actual data of the main board have to be saved in the EEPROM
of the interface board.
•
In order to store the actual data in EEPROM reset the main board either
via the Reset Common Service of the Identity Object. The type of reset to be used is 0, see the appendix
DeviceNet Interface of the SCU or
with the Hyper terminal, see 7.3 on page 67.
2
Replace the main board:
•
Take the main board out of the cassette.
•
Check the correct jumper setting of the new main board.
•
Place the new main board in the cassette.
3
Verify whether the main board is operational (status Module LED should light solid green, see also 6.2 on
page 58).
7.2
Replacement of the interface board
1
Before replacement of an interface board the actual data of the main board have to be saved in the EEP-
ROM of the interface board and then the data must be saved to file.
•
In order to store the actual data in EEPROM reset the main board either
via the Reset Common Service of the Identity Object. The type of reset to be used is 0, see the appendix
DeviceNet Interface of the SCU or
with the Hyper terminal, see 7.3 on page 67.
•
Save the EEPROM data to file by using RSNetWorx™ or store the data in LCU-5.
Select
LCU-5 System Manager - Unit Upload.
