Function Description
The safety relay PNOZ X2.1VP 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 S33-S34 is closed.
} Input circuit is closed (e.g. E-STOP pushbutton not operated):
– The LEDs "CH.1" and "CH.2" are lit.
– Safety contacts 27-28 and 37-38 are closed. The unit is active.
– The semiconductor output Y11-Y12 is enabled.
– The "ON" LED is lit.
} Input circuit is opened (e.g. E-STOP pushbutton operated):
– The semiconductor output Y11-Y12 is disabled instantaneously.
– The "ON" LED goes out.
– Safety contacts 27-28 and 37-38 are opened redundantly after the delay time has
elapsed.
– The LEDs "CH.1" and "CH.2" go out.
