    The CD-6H uses an automated background calibration program to set the clean air level on a regular basis. The CD-6MC has the same setting and features of the CD-6H with the addition of being able to perform a manual calibration. The CD- 6MC requires a manual calibration process at a minimum of once per year using the Macurco CD6-FCK calibration kit.

    “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 automated background calibrations and it is suggested to perform a Manual Calibration on the unit no less than once per year using the Macurco CD6-FCK calibration kit.

    3 INSTALLATION AND OPERATING INSTRUCTIONS The following instructions are intended to serve as a general guideline for the use of the Macurco CD-6H / CD-6MC Carbon Dioxide Detector. It is not to be considered all-inclusive, nor is it intended to replace the policy and procedures for each facility. If you have any doubts about the applicability of the equipment to your situation, consult an industrial hygienist or call Technical Support at 844-325- 3050.
  • Page 9  Carbon Dioxide concentration has dropped below fan setting  Fan Relay Run time has been exceeded Note that the “disable” fan setting will cause the fan relay to not engage. The fan relay will engage in trouble fault condition (if the Trouble Fan Setting Option is set to “ON”) and will disengage once trouble fault condition is cleared.

    3.2.7 Alternate connection to alarm panel In this application (3.2.7 Alternate connection to alarm panel) the Fan or primary relay is used as a low-level alarm relay. The Alarm or secondary relay is used as a supervisory relay when utilized in the normally closed configuration. The CD-6”x” monitors all critical functions of the unit through software diagnostics that continually test and verify its operations.
