Brivis Error Code 62

Error Code h01 62: Primary Valve Stuck On. With the primary valve control relay not being energised its contact is detected as closed indicating it is “stuck on”.

Brivis Fault Code 62

Brivis Error Code 62 Primary Valve Stuck On: With the primary valve control relay not being energised its contact is detected as closed indicating it is “stuck on”.

For Heater Repair Tech Only

Reason: With the primary valve control relay not being energised its contact is detected as closed indicating it is “stuck on” : Lockout Condition ( See Error Code#51) With the heating cycle in the “ON – PREIGNITION” phase the status of a number of inputs is checked by the primary microcontroller. In particular: 1) The state of the flame rollout signal is monitored and if a flame rollout is detected as available this would suggest that the flame rollout sensing circuitry has failed as no flame should be available at this stage (gas valve main coil not energised). Subsequently, a lockout condition (Code#51) is registered forcing the heating cycle back to its “OFF” state with no post-purge. 2) The state of the primary valve control relay contact is monitored and if it is detected as closed when it should be opened this would suggest that the contact is “stuck on” as the relay has not been energised yet. Subsequently, a lockout condition (Code#62) is registered forcing the heating cycle back to its “OFF” state with no post-purge. 3) The state of the secondary valve control relay contact is monitored and if it is detected as closed when it should be opened this would suggest that the contact is “stuck on” as the relay has not been energised yet. Subsequently, a lockout condition (Code#67) is registered forcing the heating cycle back to its “OFF” state with no post-purge. 4) The state of the flame signal is monitored and if flame is detected as available this would suggest that the flame sensing circuitry has failed as no flame should be available at this stage (gas valve main coil not energised). Subsequently, a lockout condition (Code#52) is registered forcing the heating cycle back to its “OFF” state with no post-purge. Service Check List: Reset NG-2 Module Replace the NG-2 module
