BATTERY LOW

What does 1066 mean?

The motor controller (codes 1066, 2066, 3066) has detected a low battery voltage condition. This indicates insufficient power supply to the drive system. The specific lift reaction is controller dependent.

• Battery significantly discharged below operational threshold.
• Aging battery with reduced capacity.
• High current draw exceeding battery's instantaneous capability.

Click steps to track your progress.

1. 1

   Measure the voltage of the motor controller's backup battery pack and compare against manufacturer specifications.

2. 2

   Inspect all battery terminals, connectors, and associated cabling for corrosion, damage, or loose connections.

3. 3

   Verify the output voltage and charging current from the dedicated battery charging circuit to the battery pack.

4. 4

   Check the main input power supply voltage at the motor controller (drive system) terminals and confirm it is within specified limits.
