Table 1: Troubleshooting
Problem
Cause
Solution
Responds to leak vial on
large (“LG”“) leak setting
Heat control set too high
Decrease the sensor heat slightly by turning the sensor heat knob
(on the bottom of the unit) 1/16th of a turn counterclockwise. Allow
a minute for the sensor to cool, then repeat calibration.
No response to leak vial
Leak vial empty
Reorder leak vial (RLD-H10-603R).
No air flow (Airflow indicator
ball in probe does not float.)
Replace filter in probe tip (RLD-H10-602R).
Check pump operation.
Sensor exposed to
excessive amounts of
halogen gas
Move probe to clean atmosphere for several minutes while sensor
purges itself. Recalibrate in clean area.
Water in probe
While unit is operating, blow clean air (5 psig) into the probe tip for
approximately one minute or blow (by mouth) as hard as possible
into probe tip for one or two minutes.
Replace the filter (RLD-H10-602R).
Heat control set too low
Increase the sensor heat slightly by turning the sensor heat knob
(on the bottom of the unit) 1/16th of a turn clockwise. Allow a
minute for the sensor to heat, then repeat calibration.
Audio normal; probe lamp
does not flash
Burned-out or damaged
probe lamp
Return unit to your Johnson Controls/PENN representative.
Responds continuously in all
leak positions
Dirt in sensor
Remove sensor (see Figure 11) and blow it out with clean air (not
over 10 psig). If unsuccessful, replace sensor (RLD-H10-601R).
Replace the filter (RLD-H10-602R).
Short circuit in sensor
Replace sensor (RLD-H10-601R).
Responds continuously on
small leak position
Excessive sensitivity
Decrease the sensor heat slightly by turning the sensor heat knob
(on the bottom of the unit) 1/16th of a turn counterclockwise. Allow
a minute for the sensor to cool, then repeat calibration.
Balance control will not stop
response away from leak
Atmosphere contaminated
with excessive halogen gas
Ventilate area. Switch to large (“LG”) leak setting.
(See Figure 8.)
Reduce sensor heat if unit still responds excessively at large leak
rate setting.
