Contact operation
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 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
Locking by actuator and actuation in positive
mode associated with a safety module.

The risk assessment (EN1050) will help the designer determine the
most appropriate risk reduction methods and the part played by the
safety related parts of the control system in reducing the risk
