Overload short circuit/
overload at the additional output
If there is a short circuit or overload:
• the additional output will be switched off,
• SA0 or SA1 of the diagnostic byte will be set
at logic 1.
In order to activate the output again, the follo-
wing procedure should be adopted:
Explanation
• Manual (on-line operation, test system)
• Automatic in PLC program
The error bit in the diagnostic byte of the
valve sensor terminal is reset at
logic 0.
If the short circuit has still not been eliminated,
the additional output must be switched off again.
