PNOZ XV1P Function Description The safety relay PNOZ XV1P provides a safety-oriented interruption of a safety circuit. When the supply voltage is applied via the E-STOP pushbutton, the “PWR” LED is lit. The unit is ready for operation when the start circuit S11-S14 is closed. } } Input circuit is closed (e.g. E-STOP pushbutton not operated): – The LEDs "CH.1/2" and "CH.1/2[t]" are lit. – Safety contacts 13-14, 23-24 and 37-38 are closed, the unit is active. Input circuit is opened (e.g.

PNOZ XV1P INFORMATION With automatic start, S33 and S34 must not be linked; with monitored start, S11 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 XV1P 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 "PWR" does not light: Short circuit or no supply voltage.

PNOZ XV1P Service life graph The service life graphs indicate the number of cycles from which failures due to wear must be expected. The wear is mainly caused by the electrical load; the mechanical load is negligible. Cycles x 1000 Service life graph: Safety contacts (N/O), instantaneous Switching current (A) Example } Inductive load: 0.
PNOZ XV1P Cycles x 1000 Service life graph: Safety contact (N/O), delay-on de-energisation Switching current (A) Example } Inductive load: 0.2 A, } Utilisation category: AC15 } Contact service life: 900 000 cycles Provided the application to be implemented requires fewer than 900 000 cycles, the PFH value (see Technical details) can be used in the calculation. To increase the service life, sufficient spark suppression must be provided on all output contacts.
