6. Set-up and maintenance
6.1 Functional testing
The safety function of the safety-monitoring module must be tested.
The following conditions must be previously checked and met:
1. Correct fitting of the safety-monitoring module
2. Fitting and integrity of the power cable
6.2 Maintenance
In the case of correct installation and adequate use, the safety-
monitoring module features maintenance-free functionality.
A regular visual inspection and functional test, including the following
steps, is recommended:
• Check the correct fixing of the safety monitoring module
• Check the cable for damage.
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
The safety monitoring module must be disposed of in an appropriate
manner in accordance with the national prescriptions and legislations.

8.1 Wiring example
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.
Monitoring of a sliding, hinged or removable safety guard with a
solenoid interlock of the AZM 161 series. The safety guard monitor of
the series AES monitors the position of the safety guard.
The wiring diagram is shown with guard doors closed and in a de-
energised condition. Inductive loads (e.g. contactors, relays, etc.) are to
be provided with suitable interference suppression circuitry.

To be observed for AC variants: AC supply through A1-A2,
GND of the internal 24 VDC control voltage is on terminal PE.
