Quick Troubleshooting Check

The following guidelines can be used to quickly isolate the cause of a problem. Subsequent

troubleshooting sections cover the problems in greater detail.

1. Turn on the detector and wait for the result of the self test. If the test fails, note the

error code and check the 'Self-Test Error Codes' section (→ section 7.2, page 93).

2. If the detector does not power up:

a) Check the power cord and make sure that it is properly connected.

b) Check the fuses on the rear panel of the detector.

3. Check that

♦ all gas connections are properly made, there are no signs of leakage, and the gas is

flowing.

♦ the external gas supply pressure is 480 – 550 kPa (70 and 80 psig). If not, adjust the

pressure as required.

♦ the exhaust tubing located at the rear of the detector is free of kinks, blockages or

loops and that the ventilation is free from blockages.

♦ all connections in the flow path of the LC system, including the detector, are correct

and that there are no visible signs of leakage.

♦ the gas filter assembly (located in the interior on the right-hand side of the detector) is

properly attached.

♦ the other system components are connected and operating properly, according to the

instructions for each system components.

♦ all synchronizing Digital I/O connections are properly made and functioning correctly.

4. Verify that any recent maintenance procedures were properly executed as described in

section 8.3 (→ page 109).
