flash back and forth between “FAn” and “5”. With the display function turned ”Off”, the
display does not show the gas concentration, but will show “FAn” as long as the fan
relay is activated
Note: If the Fan relay does not close within 2 minutes, consider these
possibilities:
a. Gas cylinder is empty, check the pressure gauge. Replace the gas cylinder if 25psi or
less.
b. Unit needs to be re-calibrated (go through recalibration and re-test).
c. Detector is in need of servicing (return unit to factory for servicing).
d. Detector has fan relay set to disable (OFF) or 20% LEL. Set fan relay to 5% LEL and
repeat the test.
7. Remove the gas from the sensor. Proceed to test the alarm relay or replace the top
cover.
Testing the Alarm Relay
Note: The gas concentration to activate the Alarm relay depends on the setting.
Connect the 20% LEL cylinder of Combustible Gas to the regulator. Ensure that the gas
used for calibration matches the gas selected in the Eagle Eye GD-3000 Combustible
Gas Detector configuration.
1. Check the pressure gauge. If there is 25psi or less the cylinder should be replaced.
2. Place the test hood over the gas sensor. Turn on the regulator to start the gas flow.
3. The Fan relay should activate according to the settings.
4. With the display function turned “On” and the gas concentration reaching the Alarm
Relay setting, (20% LEL, for example) the display will flash back and forth between
“ALr” and “20”. The buzzer will sound indicating “Alarm” if the buzzer is turned “On”.
With the display function turned off the display does not show the gas concentration, but
will show “ALr” when the Alarm relay is activated.
5.
Note: If the Alarm relay fails to operate within 2 minutes, consider these
possibilities:
a. Gas cylinder is empty, check the pressure gauge. Replace the gas cylinder if 25psi or
less.
b. Unit needs to be re-calibrated (go through recalibration and re-test).
c. Detector is in need of servicing (return unit to factory for servicing).
d. Detector has Alarm relay set to disable (OFF). Set Alarm relay to 20% LEL and
repeat the test.
6. Remove the gas from the sensor after test. Proceed to test the 4-20mA output or
replace the top cover.
