OPERATOR INTERFACE INSTALLATION
MOUNTING INSTRUCTIONS
FOOT MAY BE REMOVED
FOR THICKER PANEL
INSTALLATIONS
This operator interface is primarily designed for through-panel mounting. Care should be taken to remove any loose material from the mounting cut-out to prevent that material from falling into the operator interface during installation. A gasket is provided to enable sealing to NEMA 4X/IP66 specification. To maintain the IP66 rating of the panel, an equivalently IP rated enclosure should be used. Install the mounting clips provided and tighten to 6.0 pound-force inch [96 ounce-force inch] (0.68 N m) evenly for uniform gasket compression.
Care should be taken not to rub or buff the touchscreen surface in a way that might cause the accumulation of static charges.

For hazardous location installation the following shall be taken into consideration:
- When used in a Zone 22 environment, the device shall be panel mounted in at least Zone 22 IECEx/ATEX-Certified tool accessible enclosure with a minimum ingress protection rating of at least IP64 as defined in IEC/EN 60529.
- When used in a Zone 2 environment, the device shall be panel mounted in at least Zone 2 IECEx/ATEX-Certified tool accessible enclosure with a minimum ingress protection rating of at least IP54 as defined in IEC/EN 60529.
- This device is open-type and must be mounted in a suitable dust-tight end-enclosure in accordance with articles 500 and 502 of the NEC and positioned so only the face of the display is exposed.
- Must be wired using Division 2 wiring methods as specified in article
501-4(b), 502-4(b), and 503-3(b) of the National Electric Code, NFPA
70 for installation within the United States, or as specified in section
19-152 of Canadian Electrical Code for installation in Canada.
CONNECTING TO EARTH GROUND
The third pin of the power connector of the MV-7T is chassis ground for the unit. Your unit should be connected to earth ground. Steps should be taken beyond connecting to earth ground to eliminate the buildup of electrostatic charges.
The chassis ground is not connected to signal common of the unit.
Maintaining isolation between earth ground and signal common is not required to operate your unit. But, other equipment connected to this unit may require isolation between signal common and earth ground. To maintain isolation between signal common and earth ground care must be taken when connections are made to the unit.
For example, a power supply with isolation between its signal common and earth ground must be used. Also, plugging in a USB cable may connect signal common and earth ground.
1
1 USB’s shield may be connected to earth ground at the host. USB’s shield in turn may also be connected to signal common.

POWER SUPPLY REQUIREMENTS
The MV-7T requires a 10-30 VDC power supply. Your unit may draw considerably less than the maximum rated power depending upon the features being used. As additional features are used your unit will draw increasing amounts of power. Items that could cause increases in current are modules, additional on-board communications, SD card, and other features programmed through M-VIEW™ DESIGNER 3.1.
To ensure you do not exceed the capacity of your M-VIEW host power supply, calculate the total power consumption required for all of your planned modules. Each module’s maximum power consumption is listed in the Specifications of their Product Bulletin. The total power available for modules is listed in the specifications of the M-VIEW host.
In any case, it is very important that the power supply is mounted correctly if the unit is to operate reliably. Please take care to observe the following points:
– The power supply must be mounted close to the unit, with usually not more than 6 feet (1.8 m) of cable between the supply and the operator interface. Ideally, the shortest length possible should be used.
– The wire used to connect the operator interface’s power supply should be at least 22-gage wire suitably rated for the temperatures of the environment to which it is being installed. If a longer cable run is used, a heavier gage wire should be used. The routing of the cable should be kept away from large contactors, inverters, and other devices which may generate significant electrical noise.
– A power supply with an NEC Class 2 or Limited Power Source (LPS) and SELV rating is to be used. This type of power supply provides isolation to accessible circuits from hazardous voltage levels generated by a mains power supply due to single faults. SELV is an acronym for
“safety extra-low voltage.” Safety extra-low voltage circuits shall exhibit voltages safe to touch both under normal operating conditions and after a single fault, such as a breakdown of a layer of basic insulation or after the failure of a single component has occurred. A suitable disconnect device shall be provided by the end user.

WARNING: Disconnect all power to the unit before installing or removing modules.
COMMUNICATING WITH THE MV-7T
CONFIGURING AN MV-7T
The MV-7T is configured using M-VIEW™ DESIGNER 3.1 software, which is available as a no charge download from FW Murphy’s website.
The software updates for new features and drivers are posted on the website as they become available. By configuring the MV-7T using the latest software version, you are assured that your unit has the most up to date feature set. The software can configure the MV-7T through the
RS232 PGM port, USB port, or SD card.
The USB port is connected using a standard USB cable with a Type B connector. The driver needed to use the USB port will be installed with the software.
The RS232 PGM port uses a programming cable made by FW Murphy to connect to the DB9 COM port of your computer. If you choose to make your own cable, use the “MV-7T Port Pin Out Diagram” for wiring information.
The SD card can be used to program a MV-7T by placing an image file on the SD card. The card is then inserted into the target MV-7T and powered.
Refer to the M-VIEW DESIGNER 3.1 User Manual for more information on the proper names and locations of the files.
USB, DATA TRANSFERS FROM THE SD CARD
WARNING - DO NOT CONNECT OR DISCONNECT CABLES
WHILE POWER IS APPLIED UNLESS AREA IS KNOWN TO
BE NON-HAZARDOUS. USB DEVICE PORT IS FOR SYSTEM
SET-UP AND DIAGNOSTICS AND IS NOT INTENDED FOR
PERMANENT CONNECTION.
In order to transfer data from the SD card via the USB port, a driver must be installed on your computer. This driver is installed with M-VIEW
DESIGNER 3.1 and is located in the folder C:\Program Files\FW
Murphy\M-VIEW DESIGNER 3.1\Device\ after the software is installed.
This may have already been accomplished if your MV-7T was configured using the USB port.
Once the driver is installed, connect the MV-7T to your PC with a USB cable, and follow “Mounting the Card” instructions in the M-VIEW
DESIGNER 3.1 User Manual.
INSERTION/REMOVAL OF THE SD CARD
Insert the SD card into the slot provided with the card oriented as shown.
The card is inserted properly when the end of the card is flush with the M-
VIEW case. To remove the SD card, push in slightly on the card.

WARNING - EXPLOSION HAZARD - DISCONNECT POWER AND
ENSURE THE AREAS IS KNOWN TO BE NON-HAZARDOUS
BEFORE SERVICING/REPLACING THE UNIT AND BEFORE
INSTALLING OR REMOVING I/O WIRING AND BATTERY.
A battery is used to keep time when the unit is without power. Typical accuracy (at 25°C) of the M-VIEW time keeping is less than one minute per month drift. The battery of a M-VIEW unit does not affect the unit’s memory, all configurations and data is stored in non-volatile memory.
Changing the Battery
To change the battery of an M-VIEW, first remove power to the unit.
Remove the battery cover. Grasp the top edge of the battery and push to the left to remove the battery from the holder. Lift the battery out and replace with a new battery.
Replace the battery cover, and re-apply power. Use the unit keypad, or follow the procedure described in the “Setting the Time and Date” section of the M-VIEW DESIGNER 3.1 User Manual to enter the correct time and date.
* Please note that the old battery must be disposed of in a manner that complies with your local waste regulations. The battery must not be disposed of in fire, or in a manner whereby it may be damaged and its contents could come into contact with human skin.
