Explanation
RDY
"ready" message
Contact is closed if no error is present in the ZArec4C.
Contact opens in case of error or parameter input.
When the RDY output is open, the EN input may not be acti-
vated.
/ERR
"error" message
Contact is closed if no error is present in the ZArec4C.
Contact opens when errors occur which require the system to be
switched off.
It must be ensured that the system is locked when switching off
the /ERR output. Errors must be
