Problem
Responds to leak vial on
large ("LG"") leak setting

leak positions
Responds continuously on
small leak position
Balance control will not stop
response away from leak
6 RLD-H10G Product/Technical Bulletin
Cause
Heat control set too high
Leak vial empty
No air flow (Airflow indicator
ball in probe does not float.)
Sensor exposed to
excessive amounts of
halogen gas
Water in probe
Heat control set too low
Burned-out or damaged
probe lamp
Dirt in sensor
Short circuit in sensor
Excessive sensitivity
Atmosphere contaminated
with excessive halogen gas
Solution
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.
Reorder leak vial (RLD-H10-603R).
Replace filter in probe tip (RLD-H10-602R).
Check pump operation.
Move probe to clean atmosphere for several minutes while sensor
purges itself. Recalibrate in clean area.
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).
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.
Return unit to your Johnson Controls/PENN representative.
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).
Replace sensor (RLD-H10-601R).
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.
Ventilate area. Switch to large ("LG") leak setting.
(See Figure 8.)
Reduce sensor heat if unit still responds excessively at large leak
rate setting.
