| POSSIBLE CAUSES | |||
|
|
|
|
| |
INTERLOCKS CLOSED | 1) | The interlocks are closed (normal operation), power on terminal 7. | |||
|
|
|
|
| |
SYSTEM ERROR | 1) | The flame detected is out of sequence, flame signal light is on. | |||
| 2) | The sensor is “runaway”, flame signal light is on. | |||
| 3) | Inductance is detected on sensor wires, flame signal light is on. | |||
| 4) | Voltage wired into terminals 3, 4 or 5. | |||
| 5) | Internal relay contacts welded. | |||
| 6) | Internal controller failure. | |||
| 7) | Air flow switch closed before | |||
| 8) | High purge damper switch and/or main fuel valve switch opens during | |||
| 9) | Low fire switch not made before TFI. | |||
|
|
|
|
| |
FLAME FAILURE | 1) | Pilot flame is not established in selected TFI. | |||
2) | Main flame is not established in selected TFI. | ||||
| |||||
| 3) | Main flame fails within 35 seconds of TFI. | |||
| 4) | Flame failed during operation in | |||
| 5) | Flame failed 35 seconds after TFI and was not established after try in recycle mode. | |||
|
|
|
| ||
AIR FAILURE | 1) Air flow switch not closed within ten seconds of | ||||
