If the sum for a digit (ones, tens or hundreds) is greater than 9, it will display the corresponding hexadecimal
representation (see Table 2 - Decimal to Hexadecimal conversion below) of the sum. For example, if “t 02” and t
“08” exist at same time, the unit will display “t 0A” (2 +8 = 10 and the hexadecimal equivalent of 10 = A). Similarly, if
“t 40” and “t 80” exist at the same time, the unit will display “t c0”. This applies for both “t XX” and “tYYY” error
codes.

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 is less likely to be affected by inhibitors or poison significantly enhancing safety
and sensor life.
5.3
End-of-Life Signal
The non-replaceable infrared sensor (IR Sensor) of the CD-6B has a long life. Fifteen (15) years after the CD-6B is
installed, the sensor end-of-life signal will be activated indicating that the CD-6B has reached the end of its typical
usable life. The end-of-life signal will cause an error code t200 “Sensor expired”. See section
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
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-6B initiates the initial end-of-life
signal. After this 29-day period, the CD-6B 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-6B is low maintenance. The unit uses a long life NDIR sensor that has a 15-year life expectancy (in normal
conditions).
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.
