LCD Display is blank
after the 2 minute
warmup period (8002
and 8008 models)
Note:
Follow the Remedy Steps in
numerical order.
1.
Remove the sensor from the wiring
plate and check the voltage on pins 1
and 2 of the 2-pin terminal block. The
voltage should be: 18-30 VAC RMS or
18 - 42 VDC
2.
Ensure that the sensor pins that connect
to the 2-pin terminal block are not
broken, bent, or damaged.
3.
If the LCD display is still blank after
replacing the sensor on the mounting
plate, call
GE Telaire
or your
distributor/dealer for a return
authorization number.
Green light is not
illuminated (8001
and 8008 models)
after the two minute
warmup period.
1.
Remove the sensor from the wiring
plate and check the voltage on pins 1
and 2 of the 2-pin terminal block. The
voltage should be: 18-30 VAC RMS or
18 - 42 VDC.
2.
Ensure that the two pins on the sensor
that connect to the 2-pin terminal block
are not broken, bent, or damaged.
3.
If the green light is still not illuminated
after replacing the sensor on the
mounting plate, try verifying the sensor
operation using the
UIP
8000 computer
interface or checking the output signal
on the building automation system.
4.
If there is no output signal, call
GE
Telaire
or your distributor/dealer for a
return authorization number
.
Suspect the sensor is
out of calibration.
1.
Compare the sensor reading to a
GE
Telaire
7001 hand-held CO
2
monitor.
2.
Take another sensor from the building
and replace the suspect sensor to see if
the readings are similar.
3.
Connect the sensor outdoors (if
possible). The readings should be
between
350 and 450 ppm
.
4.
Connect the sensor to nitrogen gas from
a Model 2075 calibration kit. The
reading should be close to zero.
5.
If the sensor still proves to be out of
calibration, calibrate the sensor
according to the instructions included in
your calibration kit, or call for a Return
Authorization (RA) number before
returning the sensor to
GE Telaire
for
factory calibration.
Relay does not
actuate at the proper
setpoint.
1.
Using the LCD menu or the
UIP
8000
computer interface, verify that the relay
setpoint is correct.
2.
Return the sensor to normal operating
mode, and breathe into the sensor to
raise the
ppm
value above the relay
setpoint.
3.
If the relay does not actuate at the
proper setpoint, call
GE Telaire
or your
distributor/dealer for a Return
Authorization (RA) number.
