NOTICE
Extension of delay-on de-energisation
When several (n) devices are connected in series, the delay-on de-ener-
gisation time is multiplied by the number of interconnected safety switches.
The max. delay-on de-energisation is made up of the
risk time (see Technical details [
63])
+ (n-1) x max. delay-on de-energisation of the safety inputs
+ max. delay-on de-energisation of the evaluation device.
NOTICE
Increased current at the solenoid input
When several (n) devices are connected in series, the input current is multi-
plied by the number of safety switches connected in series (see Technical
details [
63]).
