Function Description
The safety relay PNOZ XV2P 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 reset circuit Y39-Y40 and the start circuit S13-S14 are closed.
} Input circuit is closed (e.g. E-STOP pushbutton not operated):
– The "START" LED is lit.
– The LEDs "CH.1", "CH.1 [t]" and "CH.2", "CH.2 [t]" are lit.
– The safety contacts 13-14, 23-24, 37-38 and 47-48 are closed. The unit is active.
– The "START" LED goes out.
} Input circuit is opened (e.g. E-STOP pushbutton operated):
– The LEDs "CH.1" and "CH.2" go out.
– Safety contacts 13-14 and 23-24 are redundantly opened.
– Safety contacts 37-38 and 47-48 open after the delay time has elapsed.
– The LEDs "CH.1 [t]" and "CH.2 [t]" go 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:
On units with selectable delay time, the delay time of the safety contacts 37-38 and 47-48
can be set on the front of the unit using a screwdriver.
