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. E-STOP pushbutton operated):
– Safety contacts 13-14 and 23-24 are redundantly opened.
– The LED "CH.1/2" goes out.
– Once the set delay time has elapsed, safety contact 37-38 is opened redundantly.
– The LED "CH.1/2[t]" goes out.
Before the unit can be restarted, the delay time must have elapsed and the unit must again
be ready for operation.
Set delay time:
The delay time for safety contact 37-38 can be set on the front of the unit using a screw-
driver.
