The Schmersal AZM 161CC-12 is a solenoid interlock designed to prevent movable safety guards from being opened before hazardous conditions are eliminated. This device is intended for use by authorized qualified personnel only. Ensure the power supply matches the device rating (24 VAC/DC or 110/230 VAC) and that the safety chain is designed according to relevant standards.
Product Description
The solenoid interlock is classified as a type 2 interlocking device according to EN ISO 14119. It is not intended for private consumers. The device features various contact configurations and options for manual release and emergency exit, depending on the specific ordering code.
Mounting
The device is fixed using three mounting holes. The solenoid interlock is double insulated; the use of an earth wire is not authorized. The mounting position must be chosen to avoid the ingress of dirt and soiling. Unused actuator openings must be sealed with slot sealing plugs. The actuator must be permanently fitted to the safety guard and protected against displacement.
Manual and Emergency Release
Manual release is performed by turning the triangular key by 180 degrees. Emergency release (ordering suffix -N) is for use only in emergencies and must be clearly labeled. Emergency exit (T, TD, TU versions) allows for actuation from within the hazardous area.
Electrical Connection
Electrical connection must be carried out by authorized personnel in a de-energized condition. Appropriate cable glands with a suitable degree of protection must be used. Remove the walls of the mounting holes by inserting the cable entry and ensure all plastic residues are removed from the switch compartment. The tightening torque for the housing cover screws is 0.6 Nm.
Set-up and Maintenance
A regular visual inspection and functional test are recommended, including checking the fixation of the safety switch and actuator, verifying the integrity of cable connections, and removing dust or soiling. Damaged or defective components must be replaced immediately.
