6.3.1 Operation Test
Check that the green CD-6G status indicator LED light is illuminated continuously. If not, do not proceed with the tests. If the
unit is in error mode, contact your local representative or Macurco technical support representative for information on
resolving the problem.
1. Remove the single screw in the middle of the front cover of the CD-G.
2. Remove the front cover.
3. Observe the LED light on the front of the CD-6G.
4. If the light is solid green proceed to step 6.
5. If the green status indicator LED light is off or flashing, refer to the General section above.
6. Locate the switch labeled ENTER/TEST on the left side of the printed circuit board. Press the Test switch once.
7. The CD-6G will step through a cycle test:
a. The display progresses through the BUZ (Buzzer Test), Art (alarm relay test), Frt (fan relay test) then 42t (4-20
mA output test). Make sure that the settings are “on” or not disabled “diS”.
b. During the first 10 seconds of the test cycle, the display will show BUZ and set off the audible buzzer. 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 16 mA 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 fan & alarm relay will be in standby mode and the 4-20 mA output will
corresponding to the gas reading of the detector. Refer to section
31T
3-1 4-20mA Output Diagram
31T
for expected
value.
8. When testing is completed reassemble the unit or units.
6.3.2 Manual Operation Test

The display will flash during the test, or in the case of the gas test, the gas level will alternate with gtS. Once the test is
complete, the display will return to a steady display. To exit the test menu, press the Next button until “End” is displayed then,
press Enter to return to normal mode.
