Operating Instructions

Follow these steps to test an electronically commutated motor:

1. Initial Setup: Complete the setup steps as described in the "Setup" section. Ensure the tester is correctly connected to both the 24 VAC power source and the ECM.
2. Power On: Flip the power switch on the main control unit to the "ON" position. The 24VAC indicator light should illuminate, confirming power supply.
3. Observe Results: The ECMPRO Tester will provide a "GO" or "NO GO" indication.
   • "GO" Indication: Indicates the ECM is functioning correctly.
   • "NO GO" Indication: Indicates a fault or malfunction within the ECM.
4. Power Off: After testing, flip the power switch to the "OFF" position and disconnect the tester from the power source and the ECM.

Important: Always ensure proper connections before powering on the device to prevent damage to the tester or the motor being tested.
