Fireye Burner Control
Fireye Burner Controls come standard on all product lines except Legacy Series.
All MicroM Programmer Modules have 5 LED lights to indicate the operating status of the control and also to display the coded sequence under locked out conditions. The function of the lights under a normal operating condition is:
Operating Control
This LED is energized whenever the burner control switch and all other various limit switches are closed and power is applied to Terminal #7.
Interlock or Air Flow
This LED is illuminated whenever power is detected on Terminal #6, indicating the air flow switch or other running interlock is closed. If the operating control is closed and the running interlock switch remains open, this LED will flash at a 1 second rate indefinitely for the MEP100 and MEP200 family. Lockout will occur if the switch remains open for 10 minutes in the MEP500 family. This LED will blink when configured as a flame switch and flame detected.
PTFI
This LED is illuminated only during the pilot trial for ignition period and the stabilization period when so equipped.
Flame
This LED is on whenever a flame signal is detected, and the control is not in a locked out state.
Alarm
This LED flashes when an alarm condition is detected and is used as an address indicator (see communication).
During an alarm condition, the Alarm LED is made to flash at approximately a 1 second rate. The remaining four LEDs are illuminated as a coded sequence identifying the reason for the lockout. For instance, for a LOCKOUT - FLAME FAIL- PTFI, the INTERLOCK, PTFI and FLAME LED’s will all be lit steady, with the Alarm LED flashing. This remains true if power is removed and then restored in a locked out condition.
While in the Idle or Off state, the LEDs are made to flash sequentially to show the operational status of the control every minute. The LEDs can be tested by pressing and releasing the Reset push button, while in the Idle or Off state.
The table containing the list of lockout codes as well as the diagnostic messages and troubleshooting guide can be found below.
