Safety Function

The module evaluates the input signals of proximity switches and contact makers and

monitors the proximity switch / contact maker circuit for open-circuits and short-circuits.

The safety function is performed in accordance with SIL 3.

Reaction in the Event of a Fault

If a fault occurs, the module adopts the safe state and the assigned input variables transmit

the initial value to the user program.

The initial values must be set to 0 to ensure that the input variables transmit the value 0 to

the user program if a fault occurs. If the raw value is evaluated instead of the process

value, the user must program the monitoring function and the value in the event of faults

from within the user program.

The module activates the Error LED on the front plate.

Scope of Delivery

The module must be installed on a suitable connector board to be able to operate. If a FTA

is used, a system cable is required to connect the connector board to the FTA. Connector

boards, system cables and FTAs are not included within the scope of delivery.

The connector boards are described in Chapter 3.6. the system cables are described in

Chapter 3.7. The FTAs are described in own manuals.
