EC fan cannot be

started

EC fan failure

If the EC fan fault alarm triggers and restarts automatically then the

possible reasons are as follows:

1. EC fan is blocked

2. EC fan is out of phase

3. EC Fan internal communication master slave error

4. EC fan is under voltage
If the EC fan is automatically restarted but there is still EC fan fault

alarm, then the reasons are as follows:

1. EC fan is reversed

2. The bus voltage is high

3. The power supply harmonic distortion rate is high (THDU>10%).

4. To determine the specific reasons: Connect to 485 communication

port and use the EBM manufacturers software for analysis.
