DIAGNOSTIC MESSAGES
RESETTING THE CONTROL
The BurnerLogix systems contain three methods of reset, by push-button located on the YB chassis/
amplifier module, by keypad push-button located on the optional keypad/display module, and by
normally open push-button connected to from line voltage (L1) to Terminal 22. Terminal 22 is a line
voltage isolated input. Depressing and releasing the reset button is required.
Notes:
1.
Manual Reset is required following any safety shutdown.
2.
Depressing and releasing the reset button during a cycle will cause the control to shut the burner
down and recycle.
3.
The YP113 programmer limits the amount of reset attempts to 5 tries. This internal counter gets
reset to 0 when the control reaches the AUTO state and on every application of power.
MESSAGE
POSSIBLE CAUSE
SOLUTION
CHECK
PROGRAMMER
No programmer module plugged
into YB chassis/amplifier module
Remove power, insert programmer, press reset to clear fault
Defective programmer module
Remove power, replace programmer module
CHECK CHASSIS
Relay feedback error caused by
bad wiring
Check all wiring, Re-inspect routing of all wires
Programmer module inserted
while power is applied
Cycle power, reset control
Defective opto-coupler on the YB
chassis/amplifier
Replace YB module
CHECK WIRING
Voltage is detected on terminals at
improper time
Check system wiring. Measure voltages on input/output terminals
CHECK SCANNER
Flame signal detected during shut-
ter close time in 45UV5 or 55UV5
scanner
Check power on shutter terminals and/or replace shutter in scan-
ner.
Runaway UV tube
Replace UV tube, part number 4-314-1
CHECK EXPANSION
MODULE
Internal diagnostics within expan-
sion module has detected a prob-
lem and ceased communications
with BurnerLogix control for 3
minutes.
Check that ED580 cable from expansion module to BurnerLogix is
plugged in or not damaged, check routing of cable within burner
cabinet or check L1-L2 connections to expansion module. Reset
control and check STATUS LED on expansion module. Replace
YZ300 or YZ320 expansion module or YB110 (YB230) chassis/
amplifier module.
Defective or unplugged ED580
cable.
Assure cable is fully inserted in both BurnerLogix control and
Expansion module. Check for damage to cable or connectors.
WAITING FOR DATA
Communications to/from display
Indicates the display is not communicating properly with chassis.
Check that the YP programmer is properly inserted. Check that the
cable is not defective and is properly inserted into the connectors.
In rare instances due to ongoing enhancements to the BurnerLogix
family, the display and chassis may not be compatible. Check the
date code and engineering code of both sets.
