8.2 Troubleshooting Check
If a problem occurs with the detector, the following troubleshooting
check helps identifying and isolating the cause of the problem.
Subsequent troubleshooting sections cover the problems in greater
detail.
1. Turn on the detector and check the self-test results.
♦
If the self-test was successful and no warning or error code
appears, continue with
step 2 .
♦
If the self-test failed, the results appear in red on the display.
Follow the steps in
section 8.3 Self-Test Error Codes, page 212 .
♦
If a warning or error code appears on the display, follow the
steps in
section 8.4 Warning and Error Codes, page 214 .
♦ If the detector does not power up:
a) Check the power cord and make sure that it is properly
connected to the power inlet on the detector and the power
source.
b) Replace the fuses. See section 7.10, page 196 .
c) Repeat step 1 .
2. Perform the following checks and, if applicable, resolve accordingly:
♦
Gas connections
Check the gas inlet tubing, gas exhaust tubing and gas filter
assembly for signs of gas leakage and proper connection to the
detector. The lines must be free of kinks, blockages or loops. The
ventilation must be free from blockages.
♦ Gas supply to the detector
Verify that gas is supplied to the detector. Check that the gas
supply pressure is within the allowed range. For gas
specifications, see
section 9.1, page 236 .
♦ Liquid flow connections
Make sure that the liquid flow connections in the system are
properly installed. Check that there are no visible signs of
leakage.
