GENERAL
DESCRIPTION
The MV-CCP is a CCP protocol communication module designed for use with the FW Murphy Engine Integrated Control System (EICS). The
CCP protocol is a proprietary protocol layer operating over CAN to the
EICS. The module provides the M-VIEW host device a CCP protocol communications port. It is built with digital isolation to protect the M-VIEW host device from the CCP protocol bus and vice versa. The MV-CCP module has a termination resistor built-in, and is selectable through a switch. The connector is pluggable for easy removal of the MV-CCP module from the CCP protocol bus, without disturbing communications with other devices on the bus.
The modules connect and communicate via proprietary USB connection to the various M-VIEW devices. The M-VIEW devices, equipped with serial ports as well as Ethernet port(s), allow the system to share data with PCs, PLCs and SCADA systems. The maximum number of modules varies for each M-VIEW device, see specific model for details. Remove power from the host device before installing or replacing any modules.
CONFIGURATION
The M-VIEW device is configured with Windows ® compatible M-VIEW
DESIGNER 3.1 software. The software is an easy to use, graphical interface which provides a means of configuration and commissioning of new systems, as well as routine module re-calibration.
SAFETY
SUMMARY
All safety related regulations, local codes and instructions that appear in this literature or on equipment must be observed to ensure personal safety and to prevent damage to either the instrument or equipment connected to it. If equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
Do not use this unit to directly command motors, valves, or other actuators not equipped with safeguards. To do so can be potentially harmful to persons or equipment in the event of a fault to the unit.

GUIDELINES
Although FW Murphy products are designed with a high degree of immunity to Electromagnetic Interference (EMI), proper installation and wiring methods must be followed to ensure compatibility in each application. The type of the electrical noise, source or coupling method into a unit may be different for various installations. Cable length, routing, and shield termination are very important and can mean the difference between a successful or troublesome installation. Listed are some EMI guidelines for a successful installation in an industrial environment.
1. A unit should be mounted in a metal enclosure, which is properly connected to protective earth.
2. Use shielded cables for all Signal and Control inputs. The shield connection should be made as short as possible. The connection point for the shield depends somewhat upon the application. Listed below are the recommended methods of connecting the shield, in order of their effectiveness.
a. Connect the shield to earth ground (protective earth) at one end where the unit is mounted.
b. Connect the shield to earth ground at both ends of the cable, usually when the noise source frequency is over 1 MHz.
3. Never run Signal or Control cables in the same conduit or raceway with
AC power lines, conductors, feeding motors, solenoids, SCR controls, and heaters, etc. The cables should be run through metal conduit that is properly grounded. This is especially useful in applications where cable runs are long and portable two-way radios are used in close proximity or if the installation is near a commercial radio transmitter.
Also, Signal or Control cables within an enclosure should be routed as far away as possible from contactors, control relays, transformers, and other noisy components.
4. Long cable runs are more susceptible to EMI pickup than short cable runs.
5. In extremely high EMI environments, the use of external EMI suppression devices such as Ferrite Suppression Cores for signal and control cables is effective.
Contact FW Murphy Technical Support for recommendation for your application.
6. To protect relay contacts that control inductive loads and to minimize radiated and conducted noise (EMI), some type of contact protection network is normally installed across the load, the contacts or both. The most effective location is across the load.
a. Using a snubber, which is a resistor-capacitor (RC) network or metal oxide varistor (MOV) across an AC inductive load is very effective at reducing EMI and increasing relay contact life.
b. If a DC inductive load (such as a DC relay coil) is controlled by a transistor switch, care must be taken not to exceed the breakdown voltage of the transistor when the load is switched. One of the most effective ways is to place a diode across the inductive load. Most FW
Murphy products with solid state outputs have internal zener diode protection. However external diode protection at the load is always a good design practice to limit EMI. Although the use of a snubber or varistor could be used.
7. Care should be taken when connecting input and output devices to the instrument. When a separate input and output common is provided, they should not be mixed. Therefore a sensor common should NOT be connected to an output common. This would cause EMI on the sensitive input common, which could affect the instrument’s operation.

TERMINATION
RESISTOR
An onboard termination resistor is selectable through a switch. The termination resistor is rated for 124 Ω at 1W. If a different termination resistance is desired, slide the switch for no termination resistor. At this point you will be required to connect your own termination resistor between positions 2 and 4 of the five position connector.

FIRMWARE
UPGRADE
The module’s firmware is stored in flash memory so that software/ hardware conflicts are avoided, and so features can be added in the future.
During a download, M-VIEW DESIGNER 3.1 compares its own library of firmware files with those stored in the module. If they do not match, M-
VIEW DESIGNER 3.1 will download the necessary firmware.
