Resistor Module Abnormal Discharge (2) (ECM)

Hva betyr H ?

The Energy Charge Module's (ECM) Capacitor Modules are discharged due to a malfunction of the discharge circuit, rather than a commanded discharge. This indicates an uncontrolled or premature release of stored energy, suggesting a more severe failure within the discharge control mechanism or the Resistor Module itself.

• Second detected instance of abnormal discharge by the resistor module (ECM).
• Resistor module (ECM) internal short circuit or open circuit.
• Inadequate discharge path for the resistor module (ECM).
• Control logic error for the resistor discharge function.

1. 1

   Immediately stop the machine using the emergency stop button and open the external Main Circuit Contactor (MCC) of the Power supply.

2. 2

   Inspect the Resistor Module (A06B-6158-H030) and its internal thermostat for proper operation and signs of damage or short circuit.

3. 3

   Check the control signals from the ECM Control Module (A06B-6158-H010) to the discharge circuit for any erroneous commands causing unintended discharge.

4. 4

   Verify the integrity of the discharge circuit components for any short circuits or component failures that could cause premature discharge.

5. 5

   Measure the resistance of the Resistor Module (expected 30 ohm, page 578) to ensure it is within specification.
