PNOZ X3 Function Description The safety relay PNOZ X3 provides a safety-oriented interruption of a safety circuit. When supply voltage is supplied the "POWER" LED is lit. The unit is ready for operation when the start circuit S13-S14 is closed. } } Input circuit is closed (e.g. E-STOP pushbutton not operated): – Safety contacts 13-14, 23-24 and 33-34 are closed, auxiliary contact 41-42 is open. The unit is active. – The LEDs "CH.1" and "CH.2" are lit.

Use external circuit measures to prevent an unexpected restart.
PNOZ X3 INFORMATION With automatic start, S33 and S34 must not be linked; with monitored start, S13 and S14 must not be linked. Operation NOTICE Check each safety function – after initial commissioning and after each change of the machine/ plant – for SIL CL 3/PL e at least 1x per month, for SIL CL 2/PL d at least 1x per year Follow the instructions below: – Activate the safety function and check whether all the used safety contacts open. – Prepare for operation again and start the unit.
PNOZ X3 Faults – Interference } Earth fault: The supply voltage fails and the safety contacts open. Once the cause of the respective fault has been rectified and the supply voltage is switched off for approx. 1 minute, the unit is ready for operation again. } Contact malfunctions: If the contacts have welded, reactivation will not be possible after the input circuit has opened. } LED "POWER" does not light: Short circuit or no supply voltage. 121 (4.76") Dimensions in mm 75 (2.95") 87 (3.
