Troubleshooting

6.0 TROUBLESHOOTING

WARNING!

Do not perform any maintenance work in a

hazardous area.

Because of the Leakator 10’s advanced design, trouble with

the instrument can usually be diagnosed by looking at the

LEDs as seen through the front-case. See Figure 3.

If the Fail LED lights, check that the sensor is seated and J3

is connected to the printed circuit board. If still no change,

replace the sensor per Section 5-1 Replacing the Sensor.

If the Low-Bat. LED lights, replace the batteries per Sec-

tion 3.0 as soon as possible. The instrument should operate,

however, for several hours before the batteries go dead.

If the instrument doesn’t respond to a combustible gas, per-

form the following in the order presented until the problem is

corrected:

- First ensure that all connectors are securely in place on the

printed circuit board, and that the sensor is firmly seated

into its socket.

- Replace sensor, even though the Sensor-Fail LED isn’t on,

per Section 5.1 Replacing the Sensor.

- Replace circuit board per Section 5.2 Replacing the Printed

Circuit Board.
