CAUTION!
Extension of delay-on de-energisation
When several (n) devices are connected in series, the delay-on de-ener-
gisation time adds with the number of interconnected safety switches.
The may. delay-on de-energisation is composed of
max. delay-on de-energisation actuator
+ (n-1) x max. delay-on de-energisation of the inputs
+ delay-on de-energisation of the evaluation device
Suitable Pilz evaluation devices are, for example:
}
PNOZelog for safety gate monitoring
}
PNOZpower for safety gate monitoring
}
PNOZsigma for safety gate monitoring
}
PNOZ X for safety gate monitoring
