To resolve Error 65 in the Monarch Nice3000 elevator controller, a structured approach to troubleshooting is essential, especially with the UCMP (Unintended Car Movement Protection) feature enabled. This function is crucial for safety, as it halts any unintended car movement. Here’s how to address E65 and E66 errors:
Error 65 (E65): UCMP Detection Abnormal
- Fault Analysis: This fault occurs when the UCMP function detects an unintended car movement.
- Possible Causes: The motor brake may not be applied fully, or accidental car movement could be triggering the UCMP function.
- Solution:
- Confirm that the motor brake engages completely.
- Ensure that the car remains stationary without any unintended movement. Adjust brake mechanisms if necessary to secure stability.
Error 66 (E66): Braking Force Detection Abnormal
- Fault Analysis: This error relates to brake force detection issues.
- Possible Causes: Insufficient braking force detected by the system during testing.
- Solution:
- Inspect the brake clearance and adjust if necessary to ensure adequate braking force.
- Verify that the braking system can hold the elevator in place without displacement.
These steps will help maintain safe operation by addressing braking and UCMP-related faults. Regular testing and maintenance of braking systems can also prevent these errors from recurring.
