Manual Operation Test - Macurco CM-6 Instructions D'utilisation

3. Observe the LED light on the front of the CM-6.
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 CM-6 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
c. The alarm relay will be closed, so any devices connected to that relay will be tested.
d. 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.
e. 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.
f. 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 4-20 mA output will return to 4 mA (in clean air).
8. When testing is completed reassemble the unit or units.

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 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 4–20 mA output has been disabled, the test selection will not be displayed in the test menu.
bUZ- Buzzer Test, 3 seconds
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 gas level will alternate with gtS. 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.
