FAULT CONDITION
Sample Pressure is <15 in-Hg or >
35 in-Hg
Normally 29.92 in-Hg at sea level
decreasing at 1 in-Hg per 1000 ft of
altitude (with no flow – pump
disconnected).
RCELL temperature is < 45C or >
55C.
Motherboard not detected on
power up.
The CPU cannot communicate with
the Relay Board.
Sample flow rate is < 350 cc/min or >
600 cc/min.
The computer has rebooted.
A failure of the analyzer's CPU, motherboard or power supplies can result in any
or ALL of the above messages.
POSSIBLE CAUSES
If Sample Pressure is < 15 in-HG:
 Blocked Particulate Filter
 Blocked Sample Inlet/Gas Line
 Failed Pressure Senor/circuitry
If Sample Pressure is > 35 in-HG:
 Bad Pressure Sensor/circuitry
 Pressure too high at Sample Inlet.
