Macurco CM-xx Operation Manual
4. Press the Enter button again to see the sensor reset status. If the sensor life has already been reset, done "don" will be
displayed. If it has not already been reset, "no" will be displayed. Push Next to change it to "YES" (flashing) then push
Enter to confirm the change (solid) and push Enter again to return to "rSt" in the "SEn" menu. Push Next until "End" is
displayed then push Enter to get back to normal operation. The sensor life will be reset for 1 year.
NOTE: If the sensor is reset and the detector not replaced, it is necessary to test and/or calibrate the sensor to assure that it is
still performing within acceptable specifications though the sensor is nearing the end of its expected life. There will be no other
indication of sensor performance.
Do not disassemble unit or attempt to repair or modify any component of this instrument.
This instrument contains no user serviceable parts, and substitution of components may
impair product performance.
CAUTION
Avoid the use of harsh cleaning materials, abrasives and other organic solvents. Such materials may permanently scratch the
surfaces and damage the display window, labels, sensor or instrument housing. High voltage terminals (100-240VAC) are
located within this detector, presenting a hazard to service technicians. Only qualified technicians should open the detector case
and service the internal circuits. Ensure power is removed from the detector prior to cleaning the unit. Failure to do so may
result in sickness or death.

6.2 Cleaning

Cleaning of the external surfaces is best carried out using a damp cloth with a mild detergent or soap. Use a vacuum cleaner
with soft brush to remove dust or contamination under the cover. Do not blow out the sensor with compressed air.

7 Testing

Using a certified gas with a concentration other than the one listed for this detector when
conducting a calibration verification test (bump test) will produce inaccurate readings. This
means that higher levels of the gas being monitored may be present and could result in
overexposure. For proper use, see supervisor or User manual, or contact Technical Support
at 1-844-325-3050.
All CM-6 units are factory calibrated, 100% tested for proper operation and accuracy of ±10%*. During normal operation the
green status indicator LED light will be on steady, the fan & alarm relay will be in standby mode and the 4-20 mA output will be
at 4mA (in clean air). The unit also performs a regular automatic self-test during normal operation. If the unit detects an
improper voltage or inoperable component, it will default into Error mode. In this error mode, the Alarm relay will be activated,
the 4-20 mA current loop will go to 24 mA, the unit will display the error code, the green status indicator LED light will flash, and
the buzzer will chirp intermittently. The Fan relay will also engage if the Trouble Fan Setting Option is set to "ON".
*Tested at 100ppm CO at 68°F to 75°F.
