@ SAFEW PRECAUTIONS 8
(Readthese precautionsbeforeusing.)
VVhen using Mitsubishiequipment, thoroughly readthis manualandthe associatedmanualsintroducedin
this manual. Also pay careful attentionto safety and handlethe moduleproperly.
These precautions apply only to Mitsubishiequipment. Refer to the CPU module use's manual for a de-
scription of the PC system safety precautions.
These Q SAFETY PRECAUTIONS 8 classifythe safety precautionsintotwo categories: "DANGER" and
"CAUTION".

Depending on circumstances, procedures indicated by A CAUTION may'also be linked to serious
!
results. Inany case, it isimportant to followthe directions for usage.
Store this manual in a safe place so that you can take itout and read it whenever necessary.Always
forward it tothe end user.
[DESIGN PRECAUTIONS]
O A malfunction inthe GOT mainmodulemay keepthe output ON or OFF. Add a circuit to exter-
nally monitorthe output which could lead to a seriousaccident.
An accident may occur byfalse output or malfunction.
Q If a communicationerror (includingbyadisconnectedcable)occurs whilethe monitoris running
onthe GOT, the communicationbetweenthe GOT andthe master station is interrupted, andthe
GOT stops running.
Fora system configurationusingaGOT, designthe system suchthat the crucialswitchingtothe
system isperformed bythe equipmentotherthan the GOT with the assumptionthat acommuni-
cation errorcould occur inthe GOT.
An accident may occur byfalse output or malfunction.

[DESIGN PRECAUTIONS]
@ DANGER
Read Chapter 5 "Data Link ProcessingTime" inthe Master ModuleUser's Manual carefully re-
gardingthe statusof each stationwhen the PC CPU operation isstopped or the data link be-
comesa communicationerror.
Also, configurean interlockingcircuit inthe sequence programusingthe communicationstatus
information(SB and SW) so that the overallsystem isalways maintained.
An accidentmay occur byfalse output or malfunction.
Receiveddatafrom masteror localdatalinkfaulty station.
@ Remoteinput (RX) and remoteoutput
This varies dependingon the setting of the module's condition setting switch and input
data(SW4) of the data linkfaulty station.
OFF : Clear (all off)
ON : Keepsthe data rightbeforethe error occurrence.
@ Remoteregisters(RWw and RWr)
The data right beforethe error iskept regardlessof the SW4 setting.
Regardlessthetouch-switchfunction is set or not, when multipletouchswitches(twoplacesor
more) are pressedsimultaneously

"
: Indicatestouches position. 0 : Indicatesthe switch recognized by the GOT.
# : Indicates a touch switch.
: Indicatesthe touch switch that executesthe set action.
When multipletouchswitchesare pressedsimultaneouslyundertheconditionsdescribedabove,
makesurethatthesystem works safelybycarefullyconsideringthe locationof eachtouchswitch
function and addingan interlockcircuittothewrite device usinga sequence program,etc.
A malfunctionmight causea breakdown, accident,or damagetothe machine.

[DESIGN PRECAUTIONS]
O Do not bunch the communication cableswith the main circuit or power wires, or installthem
closeto eachother. They should be installed
100 mm (3.9 inch)or morefrom each other, Failure
to do so may resultin noisethat would cause malfunctioning.
1
[INSTALMTBON PRECAUTIONS]
8 Makesure toswitchall phasesof the extemal GOT's power supply off before installingor remov-
ingthe GOT main moduletolfrom the base.
If you do not switch off the external power supply,
it will cause failure or malfunction of the
module.
Q Makesuretoswitchall phasesof the extemalGOT'spower supply off beforemountingor remov-
ingthe optional moduletolfrom the GOT main module.
If you do not switch off the external power supply,
it will cause failure or malfunction of the
module.
8 Make sure to switch all phasesof the external GOT and PC CPU side power supplyoff before
connectingthe communication cabletothe GOT main module.
I
If you do not switch off the external power supply, it will cause failure or malfunction of the I
L module.
[BIVSTALMTION PRECAUTIONS]
Q Usethe GOT inthe environment given inthe general specifications of the GOT User's Manual.
Usingthe GOT outsidethe rangeof the generalspecificationsmay result inelectric shock, fire or
malfunctioning, or may damageor degrade the module.
63 Tightenthe installationscrewsfor installingthe GOT mainmoduletothe basewithinthe rangeof
specifiedtorque.
Ifthe installationscrews are loose, itmay resultinfallout, short circuits, or malfunctions.
Tighteningthe installationscrewes too far may causedamagestothe screws and/orthe module,
resultinginfallout, short circuits, or malfunctions.
WIRING PRECAUTIONS]
8 Makesuretoswitchall phasesof the externalGOT's powersupply off beforebegingwiringwork.
If you do not switch off the externalpowersupply,
it will cause electric shock, malfunction, or
I
I
damageto the module.

WIRING PRECAUTIONS]
CAUTION
The FG and LG terminals should always be grounded using the class-3 or higher grounding
designedspeciallyfor the GOT. Failureto groundthese terminals may cause electric shock or
malfunctions.
@ When wiringthe GOT, check the ratedvoltage and terminal layoutof the wiring, and makesure
the wiring is done correctly. Connecting a power supplythat differsfrom the rated voltage or
wiring itincorrectlymay causefire or failure.
Tightenthe GOT's terminalscrews withintherangeof specifiedtorque. Iftheterminalscrewsare
loose, itmay result infallout, short circuits, or malfunctions. Tighteningthe terminalscrewstoo
far may cause damages to the screwsand/or the module, resultinginfallout, short circuits, or
malfunctions.
When wiringthe GOT, becareful that foreign objects, such as chips from the braidedshieldand
wiringscraps, don't get caughtinthe GOT main moduleandthe optional module.
These can cause fire, failure or malfunctions.
[PRECAUTIONS WHEN PERFORMINGTHE TEST OPERATION]
Readthe manual carefullyand fully understandthe operationbeforethe test operation(ONIOFF
of bitdevices, modifyingcurrentvalue of aword device,modifyingtimerlcountersetting, modify-
ingthe current value, or modifyingthe current value of a buffer memory) of the user created
monitorscreen.
Inaddition, never modifydata in atest operationtoadevicewhich performsa crucial operation
tothesystem.
Itmay cause an accidentbyfalse output or malfunction.
[STARTING AND MAINTENANCEPRECAUTIONS]
Do nottouchthe terminalswhile the powerison. Doingso may causeelectricshockor malfunc-
tion.
Do notchangethe switch settingwhilethe power ison. Itmay causefailureor malfunction.
Make sure to switch all phases of the external GOT's power supply off before cleaning or re-
tighteningterminal screws. Ifyou do notswitchoff the external powersupply, itwill causeelec-
tric shock. Ifthe terminal screwsare loose, itmay result infallout, short circuits, or malfunctions.
Tightening the terminal screws too far may cause damages to the screws and/or the module,
resultinginfallout, short circuits, or malfunctions.

[STARTING AND MAINTENANCE PWEMUTIONS]
4B Never disassembleor modifythe GOT mainmoduleandoptional module. This may causefailure,
malfunctions, injury,and/or fire.
(D Don't touch the conductive parts and electronic parts of the GOT main module and optional
module.This may cause the moduleto malfunctionor failure.
4B Bacausethey are madeof resin, don't dropor given astrongshocktothe GOT mainmoduleand
optional module.
This may causefailure.
[DIISPOSAL PRECAUTIONS]
CAUTION
(B When disposing of this product, treat it as industrialwaste.
[PRECAUTIONS WHEN WEPMCPNG THE BACMLIGHTJ
cB Make sure to switch all phases of the external GOT's power supply off before replacingthe
backlight, and first remove the GOT main module from the panel. If you do not switch off the
external power supply,
it will cause electric shock. If left in the panel, the GOT could fall and
cause an injury.
-
CAUTION
(9 Perform replacement of the backlight at a placewhere no other machines exist in order topre-
vent troubles in caseafixed screw of the backlightor GOT drops.
If such screw is dropped,
it may cause damage to the machineor an accident.
@ Do not touch the GOT's circuit boardor electronic parts when replacing the backlight.
Doingso could cause failure or malfunction.
@ Tighten the backlight fixed screws within the rangeof specified torque. If the fixed screws are
loose,
it may result infallout, short circuits, or malfunctions.
Tightening the fixed screwstoo far may result in damages, short circuits, or malfunctions of the
screw and/or module.
(8 Do not pull the cable connector of the backlight when replacing the backlight. Doing so could
cause damage or failure of the backlight.

[PRECAUTIONSWHEN DISPOSING THE BACKLIGHT'J
