The Schmersal AZM 161CC-12 is a solenoid interlock designed to prevent movable safety guards from being opened before hazardous conditions have been eliminated. This device is intended for use by authorized qualified personnel only. Always ensure the device is installed according to relevant safety standards (EN ISO 14119) and that the operating instructions are accessible.
Product description
The AZM 161 series is classified as a type 2 interlocking device. It features various contact configurations (NO/NC) and latching forces. The device is available in 'Power to unlock' and 'Power to lock' versions. The 'Power to unlock' version is generally used for personal safety, as the guard can be opened immediately upon power failure or main switch activation.
Mounting
The interlock must be mounted using three holes. It is double-insulated and does not require an earth wire. The mounting position should prevent the ingress of dirt. The actuator must be permanently fitted to the safety guard using tamper-proof measures.
Manual release
For set-up and maintenance, a manual release is available. It is realized by turning a triangular key (M5) by 180°. After operation, the manual release must be secured with the included plastic cover.
Emergency release and exit
The emergency release (suffix -N) allows opening from outside the hazardous area in an emergency. The emergency exit (suffix -T, -TD, -TU) allows opening from within the hazardous area. These features must be clearly labeled and used only in emergencies.
Electrical connection
Electrical connections must be performed by authorized personnel in a de-energized state. Use appropriate cable glands. The tightening torque for the housing cover screws is 0.6 Nm. Ensure the tightening sequence is followed as illustrated in the manual.
Set-up and maintenance
The safety function must be tested regularly. Maintenance includes:
- Checking the fixation of the safety switch and actuator.
- Verifying the integrity of cable connections.
- Removing dust and soiling.
Damaged or defective components must be replaced immediately. Adequate measures must be taken to prevent tampering.
Disassembly and disposal
The device must be disassembled only in a de-energized state. Dispose of the switchgear in accordance with national regulations.
