1.0 Getting Started
1.1 What is the MMI-2XX Series?
MMI-2XX Series MMI Units are operator interfaces for PLCs. They allow the
operator to interact with the machine by displaying messages
that are preloaded into them with a Personal Computer and/or
turning on LED's. They have legendable keys which can be
programmed to perform various functions for the operator.
Equipment
Checklist
An MMI
system should include:
• An MMI-2XX Series base unit.
• An interface cable to the programmable controller.
• A personal computer with MMI programming
software. A PC to MMI cable is required.
• View machine status and
parameters.
• Change machine status or
applicable operating param-
eters of the machine.
• Maintain the running of the
machine.

1.1.1 The MMI Series and Its Environment
Where
Used
The MMI Series is designed for use in a factory environment.
They are designed to operate under the same temperature
conditions as PLC's used in an industrial environment. They
may not be suitable for use in certain outdoor applications.
Please consult the factory for advised usage in outdoor
applications.
NEMA
Rating
The MMI-2XX Series front bezel is NEMA 4 rated. When
installed properly in a NEMA 4 panel, the NEMA 4 rating of
the panel will not be compromised. This means that fluids will
not enter the panel during wash downs.
Electrical
Environment
The DC powered MMI Series has been tested to conform to
European CE requirements. This means that the MMI circuitry
is designed to resist the effects of electrical noise. This does
not guarantee noise immunity in severe cases. Proper wire
routing and grounding will insure proper operation of the MMI
unit.
Mechanical
Environment
Avoid installing MMI units in environments where severe
mechanical vibration or shock are present.
Do not operate the MMI in areas subject to explosion hazards
due to flammable gases, vapors or dusts.
The MMI should not be installed where fast temperature
variations and/or high humidity are present. This will cause
condensation of water in the device.
Caution!

2.0 Installation Instructions
2.1 Mounting Instructions
2.1.1 Location Considerations.
Care should be taken when locating equipment behind the
MMI to ensure that AC power wiring, PLC output modules,
contactors, starters, 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
5.1"
(12 mm)
The MMI can be mounted into panels with a depth of
3"(76mm). It is recommended that the MMI be mounted
on the front panel of a steel enclosure, through a
7.1"(180mm) X 5.1"(12 mm) opening. Allow a clearance
of 1"(25mm) on each side of the cutout for clip mounting
hardware. Allow clearance for cable connections to the
bottom of the unit. Clearance may vary according to cable
type used. Typically, plan a clearance to accommodate at
least 3"(76mm) below the cutout.

Mounting
Put the MMI through
the panel cut out. Insert the clamps into the case. Pull back
on the clips until they seat into the retaining slots. Tighten
clamping screws to 3 in.lb. of torque in an even pattern until
the MMI is secured in the panel.
NEMA-4
Mounting
Slide the gasket over the case so that it rests behind the
Bezel Frame. Continue with standard mounting as described
above. Avoid over tightening.
Specifications Note: To seal to NEMA-4 specifications, supplied gasket must
be used and panel cannot flex more than 0.010".
When a gasket is used, the gasket may be sealed to the
case using an adhesive to maintain NEMA-4 rating.
• The MMI is to be used indoors as a built-in interface. Make sure that
the unit is installed correctly and that the operating limits are followed
(See Specifications).
• Do not operate the MMI in areas subject to explosion hazards due to
flammable gases, vapors or dusts.
• The MMI should not be installed where fast temperature variations and/
or high humidity are present. This will cause condensation of water in the
device.

2.2 Power Connections
Make sure that all local and national electrical standards are met when installing the
MMI. Contact your local authorities to determine which codes apply.
2.2.1 Power Requirements
Power The MMI can be powered by AC or DC power, depending on
the part number ordered. The MMI-2xx specified DC voltage
range is +12 to 27 Volts DC. This insures compatibility with
most DC systems. The MMI-2xxA can be powered by 115
VAC only. The MMI-2xxB can be powered by 230 VAC only.
The power conditioning circuitry inside the unit is accomplished
by a switching power supply. Due to the nature of switching
power supplies, a wide range of over and under voltages may
be used without adversely affecting the unit.
The MMI-2XX series is fused internally with a self resetting
60V 400mA fuse. It is recommended that all input power lines
be protected from product failure by a fuse or breaker.
If the display does not come on within 2 seconds of power up,
remove power. An internal diode will prevent damage if the
polarity of the DC power is incorrect. Check wiring to insure
proper connections and try to power up again.
Fusing
Requirements
Caution
Strain Relief
Adequate strain relief must be provided for the power connec-
tor, to ensure that vibration or the disturbance of cables during
maintenance does not cause the connector to pullout. Reten-
tion of the power cables by a tye-wrap onto the trunking, or an
adhesive pad mounted tye-wrap point is normally suitable.
Caution
High Voltage
Connecting high
voltages or AC power mains to the DC input will make the
MMI unusable and may create an electrical shock hazard to
personnel. Such a failure or shock 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.
Caution
Emergency
Stop
A hard wired
EMERGENCY STOP should be fitted in any system
using the MMI to comply with ICS Safety Recommen-
dations.
Page 10
Caution
Supply Voltage
Condition
Do not power the MMI and inductive DC loads, or input
circuitry to the PLC, with the same power supply.
The 24 VDC output from some PLC's may not have enough
current to power the DC powered MMI.
Terminal Block
Connections
To make a connection, strip about 1/4" of insulation off the
end of the wire, 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 is tight.
For DC powered units, connect the positive DC line to terminal
3 and the DC ground to terminal 4. For AC
powered units, connect the AC lines to terminals 3 and 4.
Caution
Power Cycling
Power supplies with large capacitive outputs may cause
problems if power is cycled within a short time period. The
power supply’s capacitor will supply enough current to keep
the microprocessor running for a few minutes but not enough
to keep the display active. If full power is restored during that
time, the microprocessor may not initialize the display
module. The result is that the display will remain blank or
show just the cursor in the upper left-hand corner and the rest
of the unit will be fully functional.
To remedy this problem, run power to the unit through a
“seal in” circuit or remove the capacitor (the MMI is not
affected if power is unregulated) or wait sufficient time between
power cycles.
Caution
Wire Routing
Wire lengths should be minimized (Maximum 1600' (500 m)
shielded, 1000' (300 m) unshielded).
Wires should be run in pairs with a neutral or common paired
with a hot or signal line.
If wiring is to be exposed to lightning or surges, use appropri-
ate surge suppression devices.
Keep AC, high energy, and rapidly switching DC wiring
separate from signal wires.
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.
