Brivis Fault Code 64

Brivis Error Code 64 Mod Valve Overcurrent: The gas valve modulating coil current has been detected as exceeding the absolute maximum allowed (150mA) for at least the gas valve modulating coil fault time.

For Heater Repair Tech Only

Reason: If the supply-air thermistor is not available to provide the necessary feedback signal the gas valve modulating coil is provided with the minimum current drive level according to the gas type being used. This ensures that the heating operates, but at a safe level. While the gas valve modulating coil is being operated and the current through the coil is detected as exceeding the absolute maximum value of 160mA for at least the gas valve modulating coil fault delay, a lockout condition is registered (Code#64). Service Check List: If Error 64 has occurred in the past on this heater then replace the NG-2 Module For a first time Error 64 reset NG-2 Module then retry heater operation. If NG-2 cannot be reset or if Error 64 reoccurs then replace NG-2 module and retest.
