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.
