I
2
C bus malfunction
REAR BOARD NOT
DET
Mother Board not detected
on power up.
Warning only appears on serial I/O COMM port(s)
Front panel display will be frozen, blank or will not respond.
Massive failure of mother board.
SAMPLE FLOW WARN
Sample flow rate is < 500
cc/min or > 1000 cc/min.
Failed sample pump
Blocked sample inlet/gas line
Dirty particulate filter
Leak downstream of critical flow orifice
Failed flow sensor/circuitry
SAMPLE PRES WARN
Sample Pressure is <10 in-
Hg or
> 35 in-Hg
1
If sample pressure is < 10 in-hg:
o
Blocked particulate filter
o
Blocked sample inlet/gas line
o
Failed pressure sensor/circuitry
If sample pressure is > 35 in-hg:
o
Blocked vent line on pressurized sample/zero/span gas supply
o
Bad pressure sensor/circuitry
SAMPLE PRES WARN
Sample Pressure is <10 in-
Hg or
> 35 in-Hg
1
If sample pressure is < 10 in-hg:
o
Blocked particulate filter
o
Blocked sample inlet/gas line
o
Failed pressure sensor/circuitry
If sample pressure is > 35 in-hg:
o
Blocked vent line on pressurized sample/zero/span gas supply
o
Bad pressure sensor/circuitry
SYSTEM RESET
The computer has
rebooted.
This message occurs at power on.
If it is confirmed that power has not been interrupted:
5 VDC power,
Fatal error caused software to restart
Loose connector/wiring
UV LAMP WARNING
The UV lamp intensity is <
600mV or > 4995 mV
UV lamp is bad
Reference detector is bad or out of adjustment.
Mother board analog sensor input circuitry has failed.
Fogged or damaged lenses/filters in UV light path
A/D converter circuitry failure
Light leak in reaction cell
Shutter solenoid stuck closed
1
Normally 29.92 in-Hg at sea level decreasing at 1 in-Hg per 1000 ft of altitude
(with no flow
– pump disconnected).
IMPORTANT
A failure of the analyzer’s CPU, motherboard or power supplies can result in any or ALL
of the above messages.
