Replacing the
Relay module
660 R 0016
The relais module for controlling the valves is subject to abrasion. This abrasion depends
upon the load of the contacts and the numbers of the working cycle.
WARNING!
For safet reasons the relais module 660 R 0016 has to be replaced after 250 000 starts.
The starts, the FMS has passed already, are shown under the function "Calling up running
time meter" .
The starts, on all curve sets have to be added together.
When the sum reaches 250 000 the relais module has to be replaced.
