    III), Protective separation (overvoltage category II) Function Description The safety relay PNOZ XV3.1 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.
