13.2.2.1
RDY (O3) digital output - operational
•
Information that the ZArec4C is operational
•
Contact closes as soon as the ZArec4C is started up
•
Contact opens in case of parameter input or a fault
•
After remedying the cause of the fault, the contact closes again
•
When the contact is open, it must be ensured that the EN input is not activated
•
After switching off RDY, the EN input must be deactivated within 1 s
13.2.2.2
Digital output /ERR (O4) - errors requiring switching off
•
Information that the internal temperature limits of the ZArec4C have been exceeded due to over-
loading and other errors, e.g. activation of the EN enable without the RDY output being active
•
If /ERR decreases, the energy supply (via DC cable) must be interrupted by the frequency inverter.
•
Quali
fi
ed personnel must be on site for error analysis and remedy
