If the error mode repeats frequently, check for continuous power and proper voltage. If power is not the problem 
and a unit has repeating error conditions, it may need to be returned to Macurco for service, per these User 
Instructions.

Note

: If multiple error codes are occurring simultaneously, the different error codes will be added together into one 

combined error code. Example: t08 and T80 occurring simultaneously will display as t88. 

If the error mode indicates “Sensor expired” see section

 of these User Instructions.

Sensor Poisons 

Unlike traditional catalytic bead and electrochemical sensors, IR sensors use a light source and a receptor to detect a specific 
gas.  Therefore, the sensor less likely to be affected by inhibitors or poison significantly enhancing safety and sensor life.   

5.3

 

End-of-Life Signal 

The CD-xxH/MC has a long life, the non-replaceable infrared sensor (IR Sensor). Fifteen (15) years after the CD-xxH/MC is 
installed the sensor end-of-life signal will be activated indicating that the CD-xxH/MC has reached the end of its typical usable 
life. The end-of-

life signal will cause an error code t200 “Sensor expired”. See section 

31T

 The end-of-life 

signal can be silenced for 48 hours by pressing the "ENTER/TEST" button or by temporarily dropping power to the unit. The end-
of-life signal provides the user an opportunity to test and/or calibrate the sensor (CD-xxMC only) assuring that it is still 
performing within acceptable parameters though the sensor is nearing the end of its expected life. The silence function will 
continue to be available for 29 days after the CD-xxH/MC initiates the initial end-of-life signal. After this 29-day period, the CD-
xxH/MC can no longer be silenced, and the unit must be replaced. 

   

WARNING

 

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.

Maintenance 

The CD-xxH/MC is low maintenance. The unit uses a long life NDIR sensor that has a 15-year life expectancy (in normal 
conditions). The CD-6H uses an automated background calibration program to set the clean air level on a regular basis. The CD-
6H will maintain accuracy 

if it is exposed to the “clean air reference value” (this reference value is the lowest concentration to 

which the sensor is exposed) at least once per week.  

The CD-6MC does not perform an automated background calibration and will need to be bump tested and calibrated to verify 
functionality and accuracy of the sensor.  

42T

Note:

42T

 This applies when used in the typical indoor ambient air with weekly unoccupied periods.  

All maintenance and repair of products manufactured by Macurco are to be performed at the appropriate Macurco 
manufacturing facility. Macurco does not sanction any third-party repair facilities.  

42T

Note:

42T

 There is not a field calibration procedure for the Macurco CD-6H.
