2.0 Installation Instructions
2.1 Mounting Instructions
2.1.1 Location Considerations
Care should be taken when locating equipment behind the unit to ensure that AC power wiring, PLC output modules,
contactors, starters and relays, and any other source of electrical interference are located away from the back of the unit.
Particular note should be taken to the position of variable speed drives and switching power supplies. Their input and load
cables should be screened to a central star earth point.
2.1.2 Making a NEMA-4 Mounting
Panel
Details
The unit can be mounted into panels with a depth of 4”(105mm). It is recommended that the unit
be mounted on the front panel of a steel enclosure, through an appropriate opening*. Allow a
clearance of 1”(25mm) around the sides of the unit for mounting hardware. Allow clearance for
cable connections to the back of the unit. Unit depth may vary according to cable type used.
Typically, plan a depth to accommodate at least 3”(105mm) behind the panel.
Note: Deburr and clean cutout before beginning installation.
*Cutout dimensions:

Do not over tighten mounting clamps!
Note:
Specifications
To seal to NEMA-4 specifications, all supplied mounting clamps must be used and panel must
not flex more than 0.010”.
2.1.3 Environmental Considerations
See Specifications for environmental constraints.
Location
NEMA
Rating
The MMI Series is designed for use in a factory environment. It is designed to operate from 32 to 113 °F
(0 to 45 °C) temperatures, as found in most industrial environments. It may not be suitable for use in
certain outdoor applications. Please consult the factory for advised usage in outdoor applications.
The MMI Series front bezel is NEMA 4 rated. When installed properly in a NEMA 4 panel, the
NEMA 4 rating of the panel is not compromised. This means that fluids do not enter the panel
through the MMI series panel during wash downs.
Do not operate the unit in areas subject to explosion hazards due to flammable gases, vapors or dusts.
The unit should not be installed where fast temperature variations and/or high humidity are present.
This causes condensation of water in the device.
Avoid installing units in environments where severe mechanical vibration or shocks are present.
Vibration endurance: 10 to 25 Hz (X,Y,Z direction 2G 30 minutes)

2.2 Power Connections
Make sure that all local and national electrical standards are met when the installing the unit. Contact your local authorities to
determine which codes apply.
2.2.1 Power Requirements
Power
Fusing
Requirements
Warning!
High Voltage
Supply Voltage
Condition
Wire Routing
The HMI can be powered by DC power only. The specified voltage range is +22 to 25
Volts DC. This insures compatibility with most controller DC systems.
The power conditioning circuitry inside the unit is accomplished by a switching power
supply. The peak starting current can be as high as 700mA.
It is recommended that all input power lines be protected from incorrect wiring or
product failure by a 2 Amp fuse or a breaker.
If the display does not come on within 2 seconds of power up, remove power. An
internal fuse prevents damage if the polarity of the DC power is incorrect. Check wiring
to insure proper connections and try to power up again.
Connecting high voltages or AC power mains to the DC input makes the unit unusable
and may create a hazard to personnel. Such a failure could result in serious personal
injury, loss of life and or equipment damage.
DC voltage sources should provide proper isolation from main AC power and similar
hazards.
Do not power the HMI and inductive DC loads, or input circuitry to the controller, with
the same power supply.
Note: The 24 VDC output from some controllers may not have enough current to power
the HMI.
Wire lengths should be minimized.
Electrical
Environment
Warning!
Emergency
Stop
Wires should be run in pairs with a neutral or common paired with a hot or signal line.
Always use shielded cable to prevent unwanted electrical interference.
If wiring is to be exposed to lightning or surges, use appropriate surge suppression
devices.
Keep AC, high energy, and rapidly switching DC wiring separate from signal wires by at
least 8 inches. If signal wires must cross AC power, cross at right angles.
Equip ungrounded DC supplies with a resistor and capacitor in parallel to earth ground.
This provides a path for static and high frequency dissipation. Typical values to use are
1MOhm and 4700pF.
The MMI Series has been tested to conform to European CE requirements. This means
that the circuitry is designed to resist the effects of electrical noise. This does not
guarantee noise immunity in severe cases. Proper wire routing and grounding insures
proper operation. The MMI Series is also UL certified.
A Hard-wired EMERGENCY STOP should be fitted in any system using an HMI to
comply with ICS Safety Recommendations.

+24 VDC Wiring Diagrams
Use 18 AWG wire to connect positive DC line to the ‘+24V’ (DC+) terminal and the DC ground
to the ‘0V‘ (-DC) terminal. See text below about FG (
Terminal Plug: (MMI-720, 730, 750 Models) To make a connection, strip about 3/8” of
insulation off the end of the wire, and turn the connector screw counterclockwise until the gap
is wide open. Insert the wire all the way in, and turn the screw clockwise until it’s tight.

Terminal Block: (MMI-850, 1500 Models) To make a connection, strip about 3/8” of
insulation off the end of the wire, turn the connector screw counterclockwise until the hold
down plate is open wide enough to insert the wire. Insert the stripped portion of the wire
under the plate and turn the screw clockwise until it’s tight.
Chassis Ground).
2.2.2 Grounding Requirements
Chassis ground must be used. DC ground is not directly coupled to Earth ground internally. It
is preferable not to ground DC negative return to chassis ground. Poor site earths can introduce
noise into a system. If necessary, an earth connection should be made from the power supply
return point to the central star earth point.
Ground conductors should be as short and as large in diameter as possible. The conductors must
always be large enough to carry the maximum short circuit current of the path being considered.
Ground conductors should be connected to a tree from a central star earth ground point. This
ensures that no ground conductor carries current from any other branch.
2.2.3 CE Requirements
To make an HMI comply with EMC directives, and to reduce susceptibility to electrical interference, a separate
#14 AWG ground wire should be taken to the chassis ground terminal of the power connector. This ground
connection should be run directly to the central star earth connection point (as recommended in most Installation
Instructions).
Use a ferrite core on the power wiring to reduce radiated emissions from the
DC power lines. It is recommended to use a 140Ohm@100MHz ferrite core
with the DC power lines looped through the core once. Position the ferrite
core less than 1” away from the DC power connection points on the back of
the HMI.

2.2.4 Safety Guidelines
This section presents recommended installation practices, and procedures. Since no two applications are identical, these
recommendations should be considered as guidelines.
Hardware
Considerations
Programming
Considerations
ICS 3-304.81 Safety Recommendations:
Consideration should be given to the use of an emergency stop function, which is independent of the programmable
controller.
Where the operator is exposed to the machinery, such as in loading or unloading a machine tool, or where the
machine cycles automatically, consideration should be given to the use of an electromechanical override or other
redundant means, independent of the programmable controller, for starting and interrupting the cycle.
If provision is required for changing programs while the equipment is in operation, consideration should be giv en to the
use of locks or other means of assuring that such changes can be made only by authorized personnel.
These recommendations are intended as safeguards against the failure of critical components and the effects of such
failures or the inadvertent errors that might be introduced if programs are changed while the equipment is in operation. *
WARNING!
The system designer should be aware that devices in Controller systems could fail and thereby
create an unsafe condition. Furthermore, electrical interference in an operator interface, such as an
HMI, can lead to equipment start-up, which could result in property damage and/or physical injury to
the equipment operator.
If you, or your company, use any programmable control systems that require an operator or
attendant, you should be aware that this potential safety hazard exists and take appropriate
precautions. Although the specific design steps depend on your particular application, the following
precautions generally apply to installation of solid-state programmable control devices. In addition,
these precautions conform to the guidelines for installation of Controllers as recommended in the
NEMA ICS 3-304 Control Standards.
To conform with ICS Safety Recommendations, checks should be placed in the controller to ensure
that all writable registers that control critical parts of plant or machinery have limit checks built into the
program, with an out-of-limit safe shut down procedure to ensure safety of personnel.

CISPR (EN 55011) Group 1, Class A Radiated Emissions levels
EN50081-2 Generic emission standard, industrial environment (Also US FCC Class A)
EN50082-2 Generic immunity standard, industrial environment
2.3.2 Guide Lines for EU Installations
• Be aware that wiring leaving the cabinet where the unit is installed may be exposed to interference sources.
• The installation practices in the individual product installation manuals of other components in the system must also be
followed.
• Locally applicable grounding safety regulations and machinery directives should be followed for providing a protective
ground to earth. The EMC ground must be a low impedance, low inductance path to the machine chassis ground.
• Power supply to the unit must be through an IEC-rated isolation transformer.
• The Power supply to the controller must be controlled to ensure that it does not exceed over voltage category II per
EN60204-1 (IEC 240).
• Other requirements of the Machinery Directive involving displays, languages, instructions, Emergency Stop functions,
machine operation, protective guards and interlocks are the responsibility of the machine manufacturer.
• Use a ferrite core on the power wiring to reduce radiated emissions from the DC power lines. It is recommended to
use a 140Ohm@100MHz ferrite core with the DC power lines looped through the core once. Position the ferrite core
less than 1” away from the DC power connection points on the back of the UNIT.
2.3.3 Safety Guide Lines for EU Installations
• Only qualified personnel should be allowed to specify, apply, install, operate, maintain or perform any other function
related to HMI products. Qualified persons are defined as follows:
System application and design engineers who are familiar with the safety concepts of automation equipment.
Installation, start-up, and service personnel who are trained to install and maintain automation equipment.
Operating personnel trained to operate automation equipment and trained on the specific safety issues and
requirements of the particular equipment.
• Make sure that the voltage range for the equipment is correct before switching on the equipment.
• Emergency-tripping devices in accordance with EN60204/IEC204 must be effective in all operating modes of the
automation equipment. Resetting the emergency off device must not result in any uncontrolled or undefined restart of
the equipment.
• Automation equipment and its operating elements must be installed so that unintentional operation is prevented.
• Make sure that operating sequences, interrupted by a voltage dip or power supply failure, resume proper operation
when the power supply is restored. If necessary, the equipment must be forced into the “emergency off” state.
• Install the power supply and signal cables so that inductive and capacitive interference voltages do not affect
automation functions.

4.0 Trouble Shooting
4.1 Power Problems
Problems on power up: Unit does not light or unit lights but does not display any windows.
1. Check wiring for proper polarity.
2. Check power Supply for proper Voltage and Current capacity.
3. Check fuse.
Problems during operation: Faulty unit operation may be due to problems with power quality. The HMI has been
designed to work in environments where electrical noise is present. However, extreme electrical noise still causes
problems. Make sure that the system is properly earth grounded.
4.2 Communications Problems
Sometimes communications fail. When communications fail, the unit automatically tries to establish the
communications link again. During the time the unit is establishing communications, the touchscreen of the unit does
not respond. Function key operations are interrupted. The implication is that the unit should not be used for
Emergency Stop applications. A loss of communications can happen at any time. Using the function keys on the unit
for critical operations can lead to a potential disaster. It is good programming practice to allow for safe operation in
case of interface failure.
There are various reasons why this happens;
Improper programming: If the MMI window is programmed to access data from an invalid register or bit address
for the PLC, the unit receives an error message from the PLC. The unit interprets this as a loss in communications.
Be sure that all data points being displayed are valid for the PLC that is connected.
Loose or incorrect cables: Make sure that all cables are secured and configured properly for the PLC.
Time outs: Make sure that the PLC is responding to requests from the HMI in a timely manner.
Power loss: Make sure the PLC has power and is running properly.
Electrical noise: Faulty unit operation may be due to problems with power quality. The HMI has been designed to
work in environments where electrical noise is present. However, extreme electrical noise still causes problems.
Make sure that the system is properly earth grounded.
The use of proper grounding techniques insures reliable communications. Make sure the controller and the HMI are
connected to good earth ground sites. This allows EMI (Electro-Magnetic Interference, commonly called electrical
noise) to be channeled to ground where it can no longer disrupt electrical operations. Be sure to route
communications cables in separate bundles and locations from AC power and control wiring. Do not run
communications cables near solenoid and relay coils or AC and DC drive controllers. Care should also be taken to
locate the HMI itself away from sources of EMI.

4.3 Commonly Asked Questions
Q. Can I have multiple MMIs connected to one Controller?
A. The ability to connect more than one HMI to a controller is accomplished through an HMI to HMI link. This is not
done through any PLC protocol. It is done through the master-slave protocol of the MMI.
Q. How do I call up windows with my PLC?
A. Use the PLC Control part configured as “Change window” to call up windows by word value. Additionally, Direct
and Indirect Window parts can be used to bring up windows.
Q. Do I need to change any jumpers to go from one Controller type to another?
A. No, the driver that is downloaded into the unit at programming time determines the Controller type. The dip
switches on the back of the unit should all be in the OFF position.
Q. Is there any way to completely erase the HMI user memory?
A. No, the HMI memory is initialized automatically before every download cycle.
Q. How Do I change the Battery?
A. Battery replacement requires disassembly of the unit in an ESD controlled environment. Battery life expectancy
is greater than 5 years.
The MMI-7XX takes one coin type of CR2032 lithium battery to backup the recipe data and keep the RTC
running. Battery specification: CR2032 3V lithium battery.
Steps for battery replacement:
1. Use EasyManager to backup the retentive memory data.
2. Turn off the HMI and remove its rear cover.
3. Remove the battery from the socket.
4. Insert a new battery into the socket.
5. Put on the rear cover.
6. Reset the RTC time and download the retentive memory data.
The MMI-850 and 1500x products have the battery soldered to the main board. We recommend that these
units be sent back to the factory for battery replacement.
Q. Can I change the Backlighting bulbs in the field?
A. We recommend that the unit be sent back to the factory for bulb replacement. Backlight bulb life expectancy is
greater than 5 years even if running 24 hours a day. Use the Backlight auto shutdown to conserve backlight bulb life.
Q. Why am I getting slow updates on my windows?
A. PLC communication speed controls the update speed. Try using a higher baudrate and adjusting the Block pack
settings. If an overloaded window is causing a slow update, we suggest changing the window design.
NOTE: EasyWindow has a tool called “SystemResource”. It displays object queue item numbers. Use this to help
detect communication problems. This problem might not show up in Offline Simulation because the PC may have
more CPU speed, more caches, and more VGA speed.

4.5 Repairs and Returns
An MMI is designed to provide years of trouble free service. An MMI under goes a full functional test before
shipment.
The MMI warranty is for one year under normal use.
The MMI does not require any “Routine Maintenance” by the user. If a problem should occur, and all troubleshooting
procedures have been exhausted, contact your local representative or distributor.
Use our toll free number to contact KEP if persistent problems are encountered.
Telephone: 1-800-631-2165.
If the product must be returned for any reason, be sure to call KEP and get a Return Goods Authorization
(RGA) number first.
Units should be returned in their original packaging container, otherwise, any suitable rigid container can be
used as a substitute. Use appropriate packing material. Damage due to shipment is not covered by the
warranty. Be sure to include a description of the problem and contact details for our repair department.
All returns are evaluated for proper operation. During evaluation, customer projects are not retained in the
units. If you need your project retained, please indicate this in the documentation included with the unit.
Products passing normal QC tests are returned to the customer and an evaluation charge is incurred.
If the problem is verified and the unit is in warranty, KEP will repair or replace the unit.
5.0 Quick Startup Guide
5.1 Connections
Set up the HMI with PC and PLC as described below.
a) Connect PC [RS-232] port of the HMI to the PC. Since the PC [RS-232] and PLC [RS-485] share the same D-SUB
connector, we recommend using the HMI to PC cable provided (MT5_PC). This splits the port into two separate connectors
to ease the program and test process.
b) Connect either the PLC [RS-485] or PLC [RS-232] port of the HMI to the PLC using the proper cable. (Check the PLC
signal type and cable listing in the back of this manual to assure proper port connections.)
c) Connect DC 24V power to the power connector. See Section 2.2.1 for power connection specifications.
Note: Check that all Dip switches are set to the “OFF” position.
d) Apply power and, if necessary, calibrate contrast adjust to the best viewing performance. (Not applicable for MMI-1500T)
Set new V4.5 hardware versions in RDS mode where contrast can be adjusted electronically.

5.4 Creating a project
A project file (*.epj FILE) is simply a collection of all the windows and window data used by an application.
Step 1. Select Edit|System Parameters... and the following screen appears. Fill in the system parameters. Use the PLC
Tab to select the set up the parameters for communicating to the PLC.
a. Select the PLC type from the dropdown list.
b. Confirm that the HMI Model is the one you
are programming.
c. Check the communications settings:
Serial I/F port
Baud rate
Data bits
Parity
Stop bits
HMI station No.
PLC station No.
Set the communications parameters to match
the PLC. (See the Controller Reference Guide
for details.)
Note:
The General, Indicator, Security, Editor,
Hardware and Auxiliary Port tabs are used for
other settings. See Section 2.0 for full details.
For a quick start, these settings can be left at
their defaults.
21
Step 2. Select any additional Group, BMP and/or Shape Libraries to attach to the
project. The default selection provides a good range of library objects. For a quick
start, no additional libraries are needed.
In the Library menu, select [Shape, Bitmap or Group] Æ [Call up Library] or use
the toolbar icons
EasyBuilder provides three types of libraries.
A Shape is a collection of drawing elements, those elements, when put together, defines a graphic symbol
representing a button, lamp, function key etc.
A Bitmap is a collection of pixel of data; each pixel can be 1, 4 or 8 bits.
A Group Library is a collection of shapes and bits that are frequently used and have been saved as a group.
.
Step 3. Design the windows
Using the parts and drawing elements, virtually any simple window display can be completed in 10 minutes. “Ease of
Use” is the greatest benefit of our EasyBuilder screen editor software.
a. Use the Draw menu/tools to put static text and shapes on the window. The drawing tools
are used in the similar fashion to most windows drawing packages.
For example: To draw a line: Select the Line tool. Change any attributes for the line. Click on
the screen where the line is to begin, move to where the line is to end and click again to set
the end point.
b. Put active parts on the screen by using the Parts
menu/tools. The parts automatically pop up a dialog for
entering information related to the part operation.
For example: Placing a Bit Lamp: Select Bit Lamp from
the Parts menu. Select the type of bit to access. Enter
the number of the bit. Go to the shape tab. Select Use
shape and click on the Shape Library button to select a
shape. Click OK to close the dialog. The Bit Lamp is
placed in the upper left corner of the display. Move it to
the desired position.
