Operation Test
1.Remove the single screw in the middle of the front cover of the 3M™ Macurco™
2.Remove the front cover.
3.Observe the LED light on the front of the 3M™ Macurco™
4.If the light is solid green proceed to step 6.
5.If the light is off or flashing Green, refer to the General section of this User Instruction.
6.Locate the switch labeled ENTER/TEST on the left side of the printed circuit board. Press the Test switch once.
7.The 3M™ Macurco™
a.The display progresses through the Art (alarm relay test), Frt (fan relay test) then 42t
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
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
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
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.
Combustible Gas Test
WWARNING
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.

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 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.
