  • Page 6: Section 1 - General Information

    1 – GENERAL INFORMATION 1.1 – DESCRIPTION The CAMM is an ultra-low differential pressure "smart" mass flow transmitter designed to convert the low magnitude pressure signals generated by airflow stations or probes, plus process temperature and static pressure inputs into multiple output signals (4-20mA, 0-5VDC or 0-10VDC) linear to mass flow, temperature, and pressure.

  • Page 7: Section 2 - Performance Specifications

    2.2 – INDICATION 120VAC 19.2VA 18.67VA 106VA 92VA Displays. Graphical backlit LCD provides up to five Circuit Protection. Power input is isolated, fused, and lines of data display. reverse polarity protected. Air Monitor Corporation CAMM - IO&M Manual 116-044-91.P65 (8/31/10)

  • Page 8: Section 3 - Features

    AUTO-zero On/Off and Interval are available and configurable using the Operator Setup menu. 3.5 – AUTO-purge MANAGEMENT The CAMM provides the capabilities of establishing purge frequency and duration, while also giving the Operator a choice of either internally timed cycle frequency or externally triggered purge initiation. During the purge cycle all transmitter outputs and displays are maintained at their last value prior to the start of the purge cycle.

  • Page 9: Special Functions

    3.8 – K-FACTOR The CAMM is equipped with a K-factor feature which allows for the introduction of a bias and/or gain factor into the transmitter's flow calculations. The K-factor feature is intended to be used in two types of applications: 1.

    Information Sheet"), and requires no additional calibration/verification prior to installation. 4.2 – LOCATION • The CAMM is housed in a NEMA 1 enclosure which provides some degree of protection which is sufficient for most clean indoor locations. • Where additional protection is deemed necessary, the CAMM should be mounted in an enclosure with adequate NEMA rating.

  • Page 11: Process Connections

    – Low Port on CAMM connects to Static Pressure from airflow measuring devices. Although any size of tube/pipe can be used, the response time of the CAMM to process change can increase if there is a increase in tube/pipe size or an increase in tube/pipe length.

  • Page 12: Power/Signal Connections

    4.5 – POWER/SIGNAL CONNECTIONS All power and signal wiring is done at the terminal strip at the left side of the CAMM. Figure 4.3 below represents the terminal strip and the connections for power input and the various inputs/outputs available.
  • Page 13 Input Power (Terminals 14, 15, and 16). Power required by CAMM must be connected to terminals 15 and 16. Earth ground should be connected to Terminal 14. When powering multiple units from one power source, polarity must be maintained.

  • Page 14: Input/Output Selection

    Inputs have a single jumper covering two pins, and outputs have two jumpers covering four pins. 4.7 – DISPLAY CONTRAST ADJUSTMENT To compensate for different ambient lighting conditions and viewing angles, the CAMM display's contrast can be adjusted for optimum visibility.

  • Page 15: Section 5 - Operation

    The CAMM has been configured and calibrated at the Factory to customer specified parameters which are recorded on the CAMM Factory Setup Information Sheet, included with the unit. Review this information and verify that the CAMM setup is correct for your applications. If any problems or discrepancies are detected, contact Air Monitor's Customer Service Department at 1-800-AIRFLOW prior to proceeding.

    ESC and UP, then scrolling until Perform Auto-Purge is displayed, then press ENT. *Note: The interval clock for AUTO-zero and AUTO-purge cycles is initiated when the CAMM's power switch is turned on. The time intervals (preset in Operator Set-Up menu) will then start their timing sequence.

  • Page 17: Configuration

    The CAMM's Onboard Microprocessor Controls Configuration: Operating parameter selection; input/output activa- tion and scaling, display scaling, and transducer calibration. The customer can verify configuration and change certain parameters (within defined ranges) by entering the CAMM's Configuration mode. This is accomplished using the four pushbuttons located on the CAMM's top cover.

  • Page 18: Pushbutton Definition

    *Must be pressed and held before other button(s) are pressed. NOTE Pushbuttons are momentary type and should be quickly pressed and released to initiate desired change, unless otherwise instructed to press and hold. Air Monitor Corporation CAMM - IO&M Manual 116-044-91.P65 (8/31/10)
