Code
Description/Possible Cause
NO FLOW ON ZONE
<0800>
Go to the
Data Display
screen
(
) and select FAULT.
This will display a
NO FLOW
message in each
individual zone affected. Check for a blockage in the air sample
line or at the line-end filter. Once the blockage has been cleared,
the RLDS will return to normal operation after the zone has been
sampled.
NO FLOW ON PURGE
<1000>
Check the purge line for a blockage. Verify that the length of the
purge line and exhaust line do not exceed 500 feet (152 meters)
in length.
CLIPPING FAULT
<8000>
The detector voltage may be out of tolerance.
REZERO VOLT TOL
<4000>
The detector output voltage is out of tolerance.
OVER RANGE
DETECTED
<2000>
This indicates that the measured concentration on one or more
zones have exceeded the measurement range.
ZERO FILTER FAULT
<0100>
Indicates contamination in the purge air, or if a charcoal filter is
in use, the filter may need to be changed.
GAIN SET FAULT
<0200>
Indicates sensor gain (digipot) is outside acceptable range.
A2D FAULT
<0400>
Analog to digital converter not working.
NOTE: This can take several minutes since it
is dependent upon how many zones there are
and their lengths. The RLDS will clear the
fault the next time it polls the affected zone.
