Expert Installation Advice: Actuator Alignment
The most common cause of failure in mechanical interlocks is misalignment. Expert Tip: When installing the AZ 16, ensure that the actuator enters the switch head without any side-load or tension. Although the AZ 16 allows for some tolerance, continuous mechanical stress on the head will wear out the cam mechanism prematurely. Use the slotted holes for fine adjustment during installation, and verify that the door radius does not cause the actuator to bind against the entry throat.
Frequently Asked Questions (FAQs)
Q: What does «ZVRK» stand for in the model code?
A: «ZV» indicates varying contact/switching logic (snap action), «R» indicates a latching force (30N), and «K» usually refers to the specific housing/terminal style (screw terminals).
Q: Can I rotate the actuating head?
A: Yes, the actuating head on the 101128195 can be repositioned in 4 x 90° steps, allowing for versatile mounting (horizontal or vertical actuation) depending on your door design.
