Phase Controller Manual - Gmr-32b

The rear panel features:

The controller manages the engine start sequence, including pre-heat, crank attempts, and fuel solenoid engagement. It monitors engine parameters via the CANbus protocol (J1939) or standard analog senders (oil pressure, coolant temperature).

To configure the controller, access the parameter menu (usually via the "Set" or "Prog" button).

| Parameter Code | Function | Description | Typical Factory Default | | :--- | :--- | :--- | :--- | | Un (or U) | Rated Voltage | Sets the base nominal system voltage. | 380V / 220V | | Ud (or %) | Unbalance Threshold | Sets the percentage deviation allowed between phases before tripping. | 5% - 10% | | td | Trip Delay | Time delay (in seconds) between detecting a fault and triggering the relay. Prevents nuisance tripping during transient fluctuations. | 2.0s | | Hys | Hysteresis | The percentage voltage required to recover before the relay resets. | 2% - 5% | The rear panel features: The controller manages the

Proper installation is critical for the safety and longevity of the unit.

  • CANbus Connection: If using electronic engine control, connect the CAN High and CAN Low wires to the engine ECU, ensuring proper shielding to prevent electromagnetic interference (EMI).

    • According to standard GMR-32B installation instructions: coolant temperature). Date: October 26

    When configured for AMF, the controller monitors the Mains (Utility) supply. Upon detection of a mains failure (blackout or phase unbalance), it automatically:
