Safety function, protective door
Assumption
9-374
If the protective door is opened, the drive should be safely stopped and after a
safely monitored time, should be shut down.
In three–shift operation, the protective door is opened every minute. The plant is
operational from Monday to Sunday. The number of actuations is as follows:
60 • 1/h • 24 h/d • 365d = 525600 per year.

Safety relay –A1 is used for the diagnostics of –K2, –K3 and –K5. It is not inclu-
ded in the calculation for the protective door safety function.
SENSE subsystem
The evaluation of the SENSOR subsystem is explained in Chapter 9.4.2
"EMERGENCY STOP and protective door monitoring at a converter → SS1"
The higher number of switching cycles has no influence on the evaluation of
this subsystem.
The results are taken over and used.
EVALUATE subsystem
The evaluation of the EVALUATE subsystem is explained in Chapter 9.4.2
"EMERGENCY STOP and protective door monitoring at a converter→ SS1".
The results are taken over and used.
RESPOND subsystem
The RESPONSE subsystem is essentially structured as described in Chapter
9.4.2 "EMERGENCY STOP and protective door monitoring at a converter →
SS1". Only the additional safety relays in channel 1 must still be taken into con-
sideration.
