Recommended Troubleshooting of Lockout Codes

 

 

Code

 

 

 

 

1.

Check wiring and correct any potential wiring errors.

 

 

 

 

 

 

 

2. Check High Fire Switch to assure proper function (not welded

 

 

 

 

 

or jumpered).

 

 

 

 

 

 

 

3.Manually drive the motor to the High Fire position and adjust

 

 

 

 

 

 

the HF switch while in this position and verify voltage through

 

 

 

 

 

 

the switch to the HFS input with a voltmeter.

 

 

 

 

 

 

 

4.

If steps 1-3 are correct and the fault persists, replace the

 

 

 

 

 

 

module.

working correctly.

 

 

 

 

 

 

 

3.

Reset and sequence the relay module.

 

 

 

 

 

 

 

4.

During STANDBY and PREPURGE, measure the voltage

 

 

 

 

 

 

between J6 terminal 5 and L2 (N). Supply voltage should be

 

 

 

 

 

 

present. If not, the lockout switch is defective and needs

 

 

 

 

 

 

replacing.

 

 

 

 

 

 

 

5.

If the fault persists, replace the relay module.

4.

Reset and sequence the module, if code reappears, replace

 

 

 

 

 

 

the flame detector.

 

 

 

 

 

 

 

5.

Reset and sequence the module, if code reappears, replace

 

 

 

 

 

 

the module.
