Schemes
Wiring to category 1 (EN 954-1)
Example with 3-pole N/C + N/O + N/O contact and protection
fuse to prevent shunting of the N/C contact, either by cable
damage or by unauthorised tampering.
(1) Signalling contact
Wiring to category 4 (EN 954-1). Wiring method used in conjunction with PREVENTA safety module.
(The guard switch should be used in conjunction with a safety limit switch to give electrical/mechanical redundancy)
Method for machines with quick rundown time (low inertia)
Locking or interlocking mechanism uses the principles of redundancy
and autocheck.The safety modules ensure these functions.
Locking by actuator and operation in positive
mode associated with a safety module.

Wiring to category 3 (EN 954-1)
Example with 3-pole N/C + N/C + N/O contact without monitoring.
(The guard switch should be used in conjunction with a safety limit switch to give
mechanical/electrical redundancy)
(1) Signalling contact
Method for machines with long rundown time (high inertia)
Interlocking mechanism with actuator captive
in the guard and zero speed detection.
