CMCP310 SERIES OPERATION MANUAL PAGE 2
Model Description:
The CMCP310 Series Switchable BNC Boxes are designed for terminating and switching the
outputs of up to 48 sensors. Switchboxes are generally installed in a location as close to the
machine as practical to reduce wiring costs and yet provide a convenient and safe way to access
the vibration and temperature signals by an operator or analyst with a portable data collector or
analyzer.
The CMCP310 Series Switchable BNC Boxes are available in three (3) types of enclosures to
best suit the environment in which they will be installed.
•Fiberglas, NEMA 4X
•Powder Coated Steel, NEMA 4
•Stainless Steel, NEMA 4X
Power (Optional):
The CMCP310 Series Boxes are capable of powering ICP Accelerometers and Temperature
Sensors through a supplied 4.2mA Constant Current Diode (CCD). An external 24VDC source is
required. Contact Sales Technology for ordering power supplies.
**See Accelerometer and Temperature Sensor Powering Below**
Mounting:
Powder Coated Steel (PS) and Stainless Steel (SS) enclosures provide welded on mounting feet.
Fiberglass (FG) versions are shipped with field installable mounting feet (qty. 4) inside of each
enclosure.
**See Pages 5-7 for Dimensions and Mounting**
Wiring:
It is strongly recommended that the CMCP310 Series Switch Box be mounted as close as
practical to the associated machine. This will prevent signal distortion associated with current
drive limitations, and will minimize interference from external electro-magnetic noise sources
(EMI). A well shielded, properly installed transducer cable is absolutely necessary to obtain
reliable operation. The cable should be routed as far away from other electrical circuits as
possible, and run in metal conduit where possible. Twisted-shielded cables designed and pre-
fitted with the proper transducer connector, and sold for this specific purpose are highly
recommended. A common cable grounding scheme should be used on all sensors to avoid
ground loops.
1. The cable shield should be open at the transducer end, and connected to the input
common on the CMCP310 Switch Box
2. Or connected at the transducer end, and open at the CMCP310 Switch Box. The cable
should be routed as far away from other electrical circuits as possible, and run in metal
conduit where possible

Accelerometer and Temperature Sensor Powering:
If needed, the CMCP310 Series Switch Box can power Accelerometers and Temperature
Sensors through a 4.2mA Constant Current Diode. An external +24VDC power source is
required.

Attaching Ribbon Cable:
The CMCP310 Series Switch Box requires a ribbon cable to be connected between the two PC
Boards. Each connector contains two (2) cable locks. To remove the cable simply push the cable
locks down and the ribbon cable will disconnect. To insert the cable, line up the arrow on the
cable with the arrow on the connector press in until the cable locks clamp over the top of the
ribbon cable, this will ensure that the cable does not come loose during operation.
