Possible Causes

  • Coupling element worn or damaged
  • Coupling alignment incorrect
  • Coupling elastomer degraded

Troubleshooting Steps

  1. Step 1: Inspect the coupling for wear or damage
    Coupling is in good condition
  2. Step 2: Verify the motor-compressor alignment
    Alignment is within tolerance
  3. Step 3: Replace the coupling element if degraded
    New coupling transmits power smoothly

How to Reset

To reset: Repair or replace the coupling, then clear the alarm.
