2.3 Destination and use
The safety-monitoring module for integration in safety circuits is designed
guards.
of up to four safety guards can be set up.
Design
The safety-monitoring module has a redundant structure. Two micro-
processors build the heart of the safety-monitoring module. The enabling
outputs for connecting the external positive-guided contactors as well as
all inputs of the safety-monitoring module are monitored and evaluated by
circuit proof and can be used for signalling purposes.

6 Set-up and maintenance
6.1 Functional testing
The safety function of the safety-monitoring module must be tested.
6.2 Maintenance
module features maintenance-free functionality.
Damaged or defective components must be replaced.
7 Disassembly and disposal
7.1 Disassembly
The safety monitoring module must be disassembled in the de-energised
condition only.
7.2 Disposal

8.1 Wiring examples
The application examples shown are suggestions. They however do not
release the user from carefully checking whether the switchgear and its
set-up are suitable for the individual application.
The wiring diagram is shown with guard doors closed and in a de-energised
with suitable interference suppression circuitry. Do not connect additional
loads to terminal S..
