Remote Display
To locate the display remotely from the BurnerLogix control, mounting kits are available. These are
Fireye part numbers 129-178-4 or 129-178-8. Each kit contains a gasket, hardware to mount the dis-
play and a 4 or 8 foot cable.
Care must be taken not to route the ED580 cable in close proximity to any starter motor contactors
located in the control panel or across any high voltage ignition wires. Refer to Fireye bulletin E-8002
for proper installation.
Communications
When interfacing Fireye controls to a communication system, be it a PLC or other microprocessor
based device, ferrite cores should also be utilized. Proper twisted shielded pair cable must be uti-
lized. In a multi-drop system, the shields should be tied together within a cabinet and not to any
ground point. The shield at the source end of the cable of the multi-drop connection can then be ter-
minated to ground. Source end is defined as the originating end of the communication system
Care must be taken not to route communication cables in close proximity to any starter motor contac-
tors located in the control panel or across any high voltage ignition wires. Refer to Fireye bulletin
E-8002 for proper installation.
Scanners
The armored cable supplied with the Ultra-Violet and Infrared scanners should be connected to
equipment by means of a good mechanical connection such as a conduit fitting. It may be necessary
to utilize heat insulator (P/N 35-69) to isolate the sensing end of the scanner from boiler ground.
Care must be taken not to route the scanner cable across the high voltage ignition cable. The high
energy ignition cable should be checked periodically for cracking, connections and aging.
In applications using flame rod units, it may be beneficial to route a separate return wire from the S2
terminal to the flame rod assembly. This will minimize the effects of transient currents flowing into
the BurnerLogix.
In all cases, scanner wires should be routed in separate conduit and not joined with any high voltage
AC or ignition cables.
Maintenance
Periodically, the spark electrode should be inspected for proper gapping and cracked ceramics. At
ignition time, the high energy from the ignition transformer will attempt to conduct to the point of
least resistance and with an improper spark gap, where the conduction takes place will no longer be
controlled.
The VA rating of the control transformer must be sized to handle the inrush currents of the pilot sole-
noid and ignition transformer at PTFI and then the inrush currents of the main fuel valve assembly at
MTFI time.
Inspect neatness of wiring in junction boxes and cabinets. It is best to have connections short and
direct and also not having wires bunched up and tied off. Also, connections should be periodically
inspected for tightness and corrosion
Type 48PT2 Infrared and Type UV1A, UV2, 45UV5 Ultraviolet Scanners
The viewing area of the scanner must be kept clean. Even a small amount of contamination will
reduce the flame signal reaching the detector by a measurable amount. Wipe the viewing area rou-
tinely using a soft cloth dampened with concentrated detergent.
— Type 48PT2 Scanners include a replaceable #4-263-1 Firetron cell.
— Type 45UV5 Scanners include a replaceable #4-314-1 UV tube.
Type 69ND1 Flame Rod
The flame rod and its insulator should be kept clean by washing routinely with soap and water. Rods
should be routinely replaced as they oxidize.
