SHOW FAULTS
If there are Faults in the Detector, a
<Show Faults>
button appears under the Status box (Figure 6-2).
Clicking on the
<Show Faults>
button displays a small window of Fault icons (Figure 6-3). LaserNET will
display icons for the following faults:
Low Airflow.
The airflow in the pipe network has dropped below the configurable low airflow threshold.
Check the pipe network for obstructions or blockages of airflow and check if the Detector fan is
operating.
High Airflow.
The airflow in the pipe network has risen above the programmed high airflow threshold.
Check for breaks in the pipe network.
Detector Fault.
The Detector has failed its sensitivity or diagnostics test or the termination board is
unable to communicate with the Detector head. Check the connections of the cable that connects the
Detector head and the termination board.
Power Supply Fault
. The power supply is not functioning correctly. Check all connections inside the
power supply. If connected properly, replace the power supply module.
Sensitivity.
Occurs when the Detector fails the sensitivity test.
Communications Failure.
LaserNET is unable to communicate with the HART XL Detector. Check the
RS-232 cable connections at the Detector and at the computer. Check the connections of the RS-232
connector extension inside the Detector. Check DIP switch address settings.
CPU Error.
Reset the Detector to clear the CPU Error. If this does not clear the error, please contact the
supplier.
RAM Configuration.
Termination board memory has been corrupted. Power down the Detector with
the battery link disconnected.
Note:
This will remove all Detector configuration settings. Save the Detector configuration before shutting
down with the battery link removed.
Display Fault.
The Display Module is connected but not enabled. Enable the Display Module in Op-
tions/Configure/Display Enable.
Reference Fault-IIM Only.
A reference Detector is not specified or communicating. Check that the
reference Detector has been configured to provide a reference or that the reference Detector has been
wired to the network correctly and operating normally.
Unregistered Fault-IIM Only.
A Detector on the IIM network has not been properly registered. Check
that all the detectors have been registered through LaserNET.
