Expert Maintenance Tips: Solenoid Heat
Solenoids generate heat when energized. Expert Tip: Depending on the locking logic (Power-to-Unlock is standard), the solenoid might be energized for long periods while the machine is running (keeping the door locked). The housing can become warm to the touch; this is normal. However, ensure the M20 cable gland allows for some air exchange or is not over-tightened to the point of deforming the plastic housing, which could bind the internal mechanism.
Frequently Asked Questions (FAQs)
Q: What is the «Power to Unlock» principle?
A: It means the door is locked by a spring when power is OFF. You must apply 24V to the solenoid to UNLOCK it. This is the safest method for personnel protection (failsafe).
Q: Can I replace the solenoid coil only?
A: No, the AZM 170 is a sealed safety device. If the coil burns out, the entire unit must be replaced to maintain safety certification.
