10.1 Processing and Clearing Fault Codes

When a fault occurs, the appropriate fault code will be displayed along with a “Flashing Triangle”

(Figure 10-2).

To process and clear the fault, proceed as follows:

NOTE

If the cause of the fault has not been corrected, the displayed Fault

Code will reappear after performing the following steps.

10.2 Fault Codes and Descriptions

All fault codes are displayed in the E8 Controller display. There are fault codes for three

different devices as follows:

• E8 Controller: These are divided into four basic categories: PCB Element Faults,

System Manager Faults, Communication Faults, and Internal Faults. These fault codes

are shown in Table 10-1.

• BCM (Boiler Control Module): Use Table 10-2 to determine the meaning of the

displayed BCM fault code, then look up BCM fault codes in Table 10-3.

• BMM (Burner Management Module): Use Table 10-2 to determine the meaning of the

displayed BMM fault code, then look up BMM fault codes in Table 10-4.

Processing and Clearing a Fault Code

1. Open the hinged cover on the controller.

2. Press the Program Key. The red LED will light. Also the display will show the fault code and

the number of the suspect module.

3. Correct the cause of the fault.

4. Press the Program Key again. The red LED will go off and the Fault Code will clear.

5. If more than one fault (or more than 1 failed module) exists, repeat the above steps until all

fault codes are cleared.

6. Close the hinged cover on the Controller.

7. Monitor the display to ensure no other Fault Codes appear.

8. Resume normal operation after all faults have been cleared.
