Description
The CMCP700S-CVT is compatible with all industry standard IEPE Accelerometers and Piezo-Velocity transducers.
Each transmitter provides constant current power for the associated sensor and processes the signal through a
True RMS detector to determine the overall amplitude in terms of Acceleration or Velocity. A 4-20mA output
proportional to one of the three user selectable ranges can then be sent to the plant’s PLC, DCS, SCADA or other
control system to allow operations and maintenance staff to view real time machinery health, set alarms and
trigger machine shutdowns for scheduled preventative maintenance. An OK Fault Detection Circuit is provided so
hardware or power failures will prompt the front panel LED to change (from green to red). Multiple transmitters
can be combined into a single enclosure or cabinet to create a cost effective, multichannel machine protection
system with solid state reliability. The CMCP700S-CVT features an additional temperature output which provides a
second 4-20mA output for dual output accelerometers such as the CMCP786T.

Power
The CMCP700S Series Transmitters require externally supplied DC power. The power supply should have a nominal
output of +24VDC and be capable of supplying a minimum of 100mA for each CMCP700S Series Transmitter in the
system. A power-supply dedicated to the vibration monitoring system is recommended. It is also recommended
that connections between the power-supply and the monitors be made with twisted-shielded instrument cable.
The cable shield should float at the transmitter and connect to common at the power-supply / system common
end only.
Opening the Case
The CMCP700S Series Transmitter is configured by a series of switches. The switches can be accessed by removing
the PCB from the housing. The PCB can be removed by depressing the tabs located on the top and bottom behind
the terminal blocks. With the tabs depressed, the PCB can then be pulled out the front of the case.
Configuring the Transmitter
The CMCP700S Series Transmitter features 8 DIP switches which allow the transmitter to be configured for various
sensor inputs and measurement types. The images below show where the switches are located on the PCB and the
direction in which they should be moved to turn features on or off. Switches can be moved with a small flat head
screwdriver or with the tip of a pen. The following sections of this manual will cover the various settings and
features.
