3.8 Troubleshooting Guide
System malfunctions are indicated by:
• Pulsing audio signal
• Flashing red and green system status LEDs (9)
and (12)
• Flashing relay disable LED (13)
• De-energized fail-safe instrument alarm relay
See Section 4.7 for fault code information.
Note:
The relay disable LED (13) does not ash for
the open tape load lever fault (see Section
1.8.2).
If the system fails to activate following installation, you
will need to verify power connection.
The following actions should be taken to isolate the
cause of the system malfunction or failure to activate:
1. Check to make sure that the green system status
LED (9) is lighted. If not, check the instrument
power source (2) and the fuse (33).
2. Check that the front panel power switch (8) is
pressed up.
3. Check Chemcassette
®
. An instrument fault
(FAULT 30) will be signaled if the Chemcassette
®
runs out, breaks, or becomes discolored. Replace
or re-thread the Chemcassette
®
as required.
4. Check the tape load lever (18). An instrument
fault (FAULT 25) will be triggered if the lever is
left open for more than two minutes.
5. If installed, check particulate filter condition. A
clogged filter will restrict sample flow (FAULT
17).
6. Check internal filters for clogging, discoloration
or moisture droplets (FAULT 17).
7. Ensure sample and exhaust lines are not pinched
or kinked (FAULT 17).
8. Verify system response. If the problem persists,
consult Honeywell Analytics Service.
