Greystone Energy Systems CMD5B4 Series Installation Instructions Manual

BEFORE INSTALLATION
Read these instructions carefully before installing and commissioning the CO transmitter. Failure to follow
these instructions may result in product damage. Do not use in an explosive or hazardous environment,
with combustible or flammable gases, as a safety or emergency stop device or in any other application
where failure of the product could result in personal injury. Take electrostatic discharge precautions
during installation and do not exceed the device ratings.
MOUNTING
The device should be mounted five feet from the floor of the area to be controlled. The four integrated
mounting holes facilitate a #10 size screw (not supplied). See Figure 1. Do not mount the sensor near doors,
opening windows, supply air diffusers, or any other known air disturbances. Avoid areas with vibrations
or rapid temperature changes.
The enclosure has a hinged cover with a latch, open it by pulling slightly on the latch on the right side of
the enclosure while pulling on the cover. See Figure 2.
Make all connections as per the "Wiring" instructions on page 2.
Once all connections are complete, latch the cover. Two self-taping screws are provided for extra security,
see Figure 3.
HARDWARE SETUP
The only hardware setup required is to select the
analog output type with the PCB switch labeled
VOLT and mA. Slide the switch to the correct
position for the required output signal type, either
4-20 mA or 0-5/10 Vdc.

Carbon Monoxide Transmitter
CMD5B4 Series - Installation Instructions
INTRODUCTION
The Carbon Monoxide Transmitter uses an electrochemical
sensor to monitor th carbon monoxide level and outputs
a field-selectable 4-20 mA or voltage signal. The voltage
signal may also be set to 0-5 or 0-10 Vdc. The sensing range
and output may be scaled to either 100, 150, 300, 400,
or 500 ppm via the on-board menu. A front panel LCD is
standard to ensure easy setup and operation.
Other standard features include a back light for the LCD,
a front panel test switch, status indication and an alarm
buzzer. The text function may also be controlled remotely
with a digital input signal. A three-key menu is implemented
to allow local configuration of all device parameters.
