Possible faults
1. LED’s light up during the pre-purge phase (control
box switches to lockout):
a)
Sensitivity set too high
b) Stray light
c)
Ignition spark visible to detector (directly or reflection).
Correct by preventing direct sight of ignition spark.
d) Interference from ignition cable (lay cables some
distance apart, or possibly screen the detector).
2. No indication from LED’s after establishment of flame:
a)
Incorrect or faulty wiring
b) Sensitivity set too low
c)
Detector positioned wrongly (receives no light)
d) Detector or viewing window dirty
e)
Defective detector
f)
IRD flange M93 defective (cracks or other mechanical
defects)
g) wrong IRD flange, special magnetic IRD flange M93
is needed.
