Macurco CM-xx Operation Manual

7.1 Testing

7.1.1 Operation Test

Check that the green CM-6 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 service representative for information on resolving the
problem.
1. Remove the single screw in the middle of the front cover of the CM-6.
2. Remove the front cover.
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 3 seconds of the test cycle, the display will show BUZ and set off the audible buzzer
c. The alarm relay will be closed for 5 seconds, 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 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.

7.1.2 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 press the Next button 2 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 five 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, 5 seconds
Frt - Fan Relay Test, 60 seconds
42t - 420 loop test, 130 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.
