• 4-20mA is normal gas reading range (0-50% LEL)
• 24mA indicates a Trouble condition
Error Codes
• t01 Sensor is missing
• t02 Temperature compensation failed
• t04 Bad EEPROM checksum
• t08 Sensor is shorted
• t10 Bad EEPROM
• t20 Bad factory calibration
• t40 Factory calibration was not done
• t80 SDADC reading failed
If the error mode repeats frequently, check for continuous power and proper voltage. If
power is not the problem and a unit has repeating error conditions, it may need to be
returned to Eagle Eye for service, as noted in these User Instructions.

6. Locate the switch labeled ENTER/TEST on the left side of the printed circuit board.
Press the Test switch once.
7. The Eagle Eye GD-3000 Combustible Gas Detector will step through a cycle test:
a. The display progresses through the Art (alarm relay test), Frt (fan relay test) then 42t
(4-20mA output test).
b. During the first 5 seconds of the test cycle, the alarm relay will be closed, so any
devices connected to that relay will be tested.
c. The Fan relay will be activated for the next 1 minute of the test, so if the fan circuits
are wired in the normal manner,
the fan should run.
d. The 4-20mA output will then ramp up from 4 to 20mA over the next 130 seconds of
the test, so if the circuit is wired
in the normal manner, the control panel or building automation system should respond.
e. At the end of the test cycle, the light will turn green and be on steady (Normal
Operation), the fan & alarm relay will be
in standby mode and the 4-20mA output will return to 4mA (in clean air).
8. When testing is completed reassemble the unit or units.
4.2.2 Manual Operation Test
This option gives the user the opportunity to manually initiate an individual test for each
relay, the analog output and the sensor response to gas. From normal operation mode
17

press the Next button 3 times to get to the Test Mode (tSt). Press the Enter button once
to get into the Test Menu. Press the Next button to scroll through the four test options
and press Enter to initiate the selected test. Note that if the relay or 4–20mA output has
been disabled, the test selection will not be displayed in the test menu.
Art - Alarm Relay Test, 10 seconds
Frt - Fan Relay Test, 60 seconds
42t - 420 loop test, 25 seconds
gtS - Gas Test, 3 minutes (no output to the panel during the gas test)
The display will flash during the test or in the case of the gas test the level will alternate
with the expected gas (mE, Pro or Hy).Once the test is complete, the display will return
to steady display. To exit the test menu, press the Next button until “End” is displayed
then press Enter to return to normal mode.
4.2.3 Combustible Gas Test
The following steps must be performed when conducting a calibration or calibration
verification test (bump test) to ensure proper performance of the monitor. Failure to do
so may adversely affect product performance and result in sickness or death.
• When performing a calibration or calibration verification test (bump test) only use
certified calibration gas at the required concentration level. Do not calibrate with expired
calibration gas.
• If the instrument cannot be calibrated, do not use until the reason can be determined
and corrected.
• Do not cover or obstruct display, audible alarm opening or visual alarm cover.
• Ensure sensor inlet is unobstructed and is free of debris.
General
The Eagle Eye GD-3000 Combustible Gas Detector can be bump-tested or calibrated
with a Field Calibration Kit (FCK) with Methane, Propane or Hydrogen gas, regulator
and test hood, available through your local representative or from Eagle Eye.
FCK Information
Several detectors can be calibrated with one FCK. The only limitation is the amount of
gas in the cylinder. The 17 liter cylinder with 0.2 LPM (Liters Per Minute) regulator has
approximately 85 minutes of continuous calibration run time. Replacement cylinders are
18

Eagle Eye GD-3000 User Manual
available. The gas cylinder should be replaced when the pressure gauge on the
regulator shows 25psi or less.
Note: For optimum test results it is suggested that the unit be in clean air (solid
green light on) and be in a low ambient air flow.
Gas Testing
Testing the Fan Relay
Note: The gas concentration to activate the fan relay depends on the setting.
1. Remove the Philips screw on the front of the Eagle Eye GD-3000 Combustible Gas
Detector. Remove the front cover.
2. Connect the 10% LEL cylinder of Combustible Gas to the regulator. Ensure that the
gas used for calibration matches thegas selected in the Eagle Eye GD-3000
Combustible Gas Detector configuration.
3. Assemble regulator, hose and test hood and place the test hood over the gas sensor.
4. Check the pressure gauge on the regulator. If you have 25psi or less you will need to
replace the gas canister.
Note: The time to activate the fan relay depends on the delay setting.
5. Turn on the regulator to start the gas flow and wait with the gas applied continuously.
6. With the display function turned “On”, the Eagle Eye GD-3000 Combustible Gas
Detector will show the current concentration of gas or “0” (zero) in clean air. When the
gas concentration reaches the fan relay setting (5% LEL, for example) the display will
19

Eagle Eye GD-3000 User Manual
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.
