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.
2.2.1PowerRequirements
Power TheMMIcanbepowered byACorDCpower,dependingon
thepartnumberordered.TheMMI-2xxspecifiedDCvoltage
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
powersupplies,awiderangeofoverandundervoltagesmay
beusedwithoutadverselyaffectingtheunit.
TheMMI-2XXseriesisfusedinternallywithaselfresetting
60V 400mA fuse. It is recommended that all input power lines
beprotectedfrom productfailurebya fuseorbreaker.
If the display does not come on within 2 seconds of power up,
removepower.Aninternaldiodewillpreventdamageifthe
polarity of the DC power is incorrect. Check wiring to insure
properconnections andtryto powerupagain.

Caution
High Voltage
Connectinghigh 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
personalinjury,lossoflifeand/orequipmentdamage.

Caution
Supply Voltage
Condition
Donot powerthe MMIandinductive DCloads, orinput
circuitry to the PLC, with the same power supply.
The24VDCoutputfromsomePLC'smaynothaveenough
currenttopowertheDCpoweredMMI.
Terminal Block
Connections To make a connection, strip about 1/4" of insulation off the endofthe wire,turn theconnector screwcounterclockwise
until the gap is wide open, insert the wire all the way in, and
turn the screw clockwise until it is tight.
ForDC poweredunits,connectthepositiveDCline toterminal
3 and the DC ground to terminal 4. For AC
powered units, connect the AC lines to terminals 3 and 4.
Caution
Power Cycling Powersupplies withlarge capacitiveoutputs maycause problems if power is cycled within a short time period. The
powersupply’scapacitor willsupply enoughcurrent tokeep
themicroprocessorrunningfora fewminutesbutnotenough
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
affectedifpowerisunregulated)orwaitsufficienttimebetween
power cycles.
Caution
Wire Routing Wirelengths shouldbe minimized(Maximum 1600'(500m) shielded,1000'(300m)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-
atesurgesuppressiondevices.
KeepAC, highenergy, andrapidlyswitching DCwiring
separatefromsignalwires.

nottogroundDCnegativereturntoearthground,terminal5,
as poor site earths can introduce noise into a system, but if
necessaryan earthconnection shouldbe made,from the

Considerations
WARNING! Thesystem designershould beawarethat controldevices in ProgrammableControllersystemscanfailandtherebycreate
anunsafecondition.Furthermore,electricalinterferenceinan
operator interface, such as the MMI, can lead to equipment
start-up,which couldresultinpropertydamage and/orphysi-
calinjury tothe equipmentoperator.
Ifyou, oryourcompany,useany programmablecontrol
systemswhich requirean operatoror attendant,you should
be aware that this potential safety hazard exists and take
appropriateprecautions.Althoughthespecificdesignsteps
dependonyourparticularapplication,thefollowingprecau-
tionsgenerally applytoinstallation ofsolid-stateprogram-
mablecontroldevices.Inaddition,theseprecautionsconform
totheguidelinesforinstallationofProgrammableControllers
asrecommendedintheNEMAICS3-304Programmable
ControlStandards.
Programming
Considerations
ToconformwithICS Safety Recommendations, checks should be placed in the PLC program to ensure that all writable registers that control
criticalpartsofplantormachinery shouldhaveupperand
lower limit checks built into the program, with an out-of-limit
safeshutdownproceduretoensuresafetyofpersonnel.
ICS3-304.81SafetyRecommendations:
Consideration should be given to the use of an emergency stop function which is indepen-
dent 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 given 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 compo-
nents and the effects of such failures or the inadvertent errors that might be introduced if
programs are changed while the equipment is in operation.*

3.0 MMI Operations
Oncethe MMIis programmedand connectedto thePLC,normal operationbegins.
The MMI establishes communications with the PLC. It then requests the number in
theMessageTriggeringRegister(MTR),ifused,anddisplaysthecorresponding
message. It then requests the bit pattern in the LED Control Register and lights
thecorrespondingLED's.
3.1 The Message Queue MMI-220, 240
Occasionally, messages are called up faster than they can be displayed. When
this happens messages are held in a Queue and wait their turn to be displayed.
Themessage Queueholds upto 3message numbers.
3.1.1QueueActivation
3.1.2QueueAction
The Queue is emptied on a first in, first out basis. If the Queue is full, additional
messages will be lost.
Messagesare storedin theQueuewhen:
1. A series of Chained messages are being displayed.
2. A message with a long minimum display time is displayed.
3. A message with a long scrolling time is displayed.
Warning Function keys that have displayable message text assigned
to them clear the Queue.
3.1.3TheInterruptMessage
Messagenumber65535 is theInterrupt message.When message65535 iscalled,
the Queue is immediately cleared. The next message number that appears in the
messagetriggering registeristhen displayed.
An example of Queue operations:
Message 23 is being displayed with a minimum time of 10 seconds.
