Series Connection - Pilz PSEN cs5.1 M12/8 Operating Manual

PSEN cs5.1 M12/8

Series connection

The safety sensors PSENcode are also suitable for series connection with other sensors.
The series connection of maximum 32 sensors PSENcs 5.x and PSENcs 6.x is approved
for SIL CL 3 without using the SDD.
When using the SDD, the series connection of maximum 16 sensors PSENcs 5.x and
PSENcs 6.x is approved
In practice, the maximum possible number will be limited by the following parameters,
among others:
}
The required SIL level (e.g. SIL CL 3),
} the required performance level (e.g. PL e (Cat. 4)),
}
the maximum delay or risk time permitted by the application.
Ensure there is sufficient supply voltage, taking inrush currents and fusing into considera-
tion.
}
When making series connections using SDD, only use the following passive junctions.

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 max. delay-on de-energisation is made up of the
risk time (see Technical details [
+ (n-1) x max. delay-on de-energisation of the inputs
+ max. delay-on de-energisation of the evaluation device
