详细说明:三菱 终端接口模块AJ71C21用户手册pdf,This manual decribes the specifications and handling of the AJ71C21 terminal interface module and the AJ71C21-S1 terminal interface module.DESIGN PRECAUTIONS]
DANGER
Install a safety circuit external to the Pc that keeps the entire system safe even when there are
problems with the extemal power supply or the Pc module. Otherwise, trouble could result
from erroneous output or erroneous operation
(1)Outside the PC, construct mechanical damage preventing interlock circuits such as
emergency stop protective circuits, positioning upper and lower limits switches and
interlocking forward /reverse operations
2) When the PC detects the following problems, it will stop calculation and turn off all output
The power supply module has over current protection equipment and over voltage
protection equipment
The PC CPUs self-diagnostic functions, such as the watchdog timer error, detect
problems. In addition, all output will be turned on when there are problems that the Pc
CPU cannot detect, such as in the lo controller Build a fail safe circuit exterior to the
PC that will make sure the equipment operates safely at such times. See Section 8.1
of this user's manual for example fail safe circuits
See this user's manual for example fail safe circuits
(3 )Output could be left on or off when there is trouble in the outputs module relay or
transistor. So build an external monitoring circuit that will monitor any single outputs that
could cause serious trouble.
When overcurrent which exceeds the rating or caused by short-circuited load flows in the
output module for a long time, it may cause smoke or fire To prevent this, configure an
external safety circuit, such as fuse
Build a circuit that turns on the external power supply when the Pc main module power is
turned on. If the external power supply is turned on first, it could result in erroneous output or
erroneous operation
When there are communication problems with the data link, the communication problem station
ill enter the following condition
Build an interlock circuit into the Pc program that will make sure the system operates safely by
using the communication state information Not doing so could result in erroneous output or
erroneous operation
(1)For the data link data, the data prior to the communication error will be held
(2) The MELSECNET(IL, /B, / 10)remote WO station will turn all output off
(3)The MELSECNET/MINI-S3 remote WO station will hold the output or turn all output off
depending on the E.C. remote setting
Refer to the data link manuals regarding the method for setting the communication problem
station and the operation status when there are communication problem
When configuring a system, do not leave any slots vacant on the base. Should there be any
vacant slots, always use a blank cover(A1SG60)or dummy module(A1SG62
When the extension base A1S52B, A1S55B or A1 S58B is used, attach the dustproof cover
supplied with the product to the module installed in slot 0
If the cover is not attached the module's intemal parts may be dispersed when a short-circuit
test is performed or overcurrentovervoltage is accidentally applied to the external t/O area
△
CAUTION
Do not bunch the control wires or communication cables with the main circuit or power wires, or
install them close to each other they should be installed 100 mm(3.94 inch) or more from
each other not doing so could result in noise that would cause erroneous operation.
DESIGN PRECAUTIONST
△
CAUTION
When controlling items like lamp load, heater or solenoid valve using an output module, large
current (approximately ten times greater than that present in nomal circumstances) may flow
when the output is turned OFF-ON. Take measures such as replacing the module with one
having sufficient rated current
[INSTALLATION PRECAUTIONSI
个
DANGER
Use the PC in an environment that meets the general specifications contained in this manual
Using this Pc in an environment outside the range of the general specifications could result in
electric shock, fire, erroneous operation, and damage to or deterioration of the product
Install so that the pegs on the bottom of the module fit securely into the base unit peg holes
and use the specified torque to tighten the module's fixing screws. Not installing the module
correctly could result in erroneous operation, damage, or pieces of the product falling
Tightening the screws too far may cause damages to the screws and/or the module, resulting
in fallout, short circuits or malfunction
. When installing more cables, be sure that the base unit and the module connectors are
installed correctly. After installation check them for looseness. poor connections could result in
erroneous Input and erroneous output
Correctly connect the memory cassette installation connector to the memory cassette. After
installation, be sure that the connection is not loose. a poor connection could result in
erroneous operation
e Do not directly touch the module's conductive parts or electronic components. Doing so could
cause erroneous operation or damage of the module
[WIRING PRECAUTIONS]
◇ DANGER
Completely turn off the external power supply when installing or placing wiring. Not completely
turning off all power could result in electric shock or damage to the product.
When turning on the power supply or operating the module after installation or wiring work, be
sure that the module's terminal covers are correctly attached not attaching the teminal cover
could result in electric shock
CAUTION
Be sure to ground the FG terminals and LG teminals to the protective ground conductor. Not
doing so could result in electric shock or erroneous operation
When wiring in the PC, be aure that it is done correctly by checking the product's rated voltage
and the terminal layout. Connecting a power supply that is different from the rating or
incorrectly wiring the product could result in fire or damage
[WIRING PRECAUTIONS
△
CAUTION
Do not connect multiple power supply modules in parallel Doing so could cause overheating
fire or damage to the power supply module. If the terminal screws are too tight, it may cause
falling, short circuit or erroneous operation due to damage of the screws or module
Tighten the terminal screws with the specified torque. If the teminal screws are loose, it could
result in short circuits, fire, or erroneous operation.
Tightening the terminal screws too far may cause damages to the screws and/or the module
resulting in fallout, short circuits, or malfunction
Be sure there are no foreign substances such as sawdust or wiring debris inside the module
Such debris could cause fires, damage, or erroneous operation
Extemal connections shall be crimped or pressure welded with the specified tools, or correctly
soldered. For information regarding the crimping and pressure welding tools, see the vo
module's user's manual Imperfect connections could result in short circuit, fires, or erroneous
operation
STARTUP AND MAINTENANCE PRECAUTIONS
DANGER
do not touch the terminals while power is on. Doing so could cause shock or erroneous
operation
Correctly connect the battery. Also, do not charge, disassemble, heat, place in fire, short
circuit, or solder the battery. Mishandling of battery can cause overheating or cracks which
could result in injury and fires
Switch all phases of the external power supply off when cleaning the module or tightening the
terminal screws. Not doing so could result in electric shock. If the screws are too tight, it may
cause falling, short circuit or erroneous operation due to damage of the screws or modules
Tightening the screws too far may cause damages to the screws and/or the module, resulting
In fallout. short clrcults, or malfunction
△
CAUTION
The online operations conducted for the CPU module being operated, connecting the
peripheral device (especially, when changing data or operation status), shall be conducted
after the manual has been carefully read and a sufficient check of safety has been conducted
Operation rrlistakes could cause damage or trouble of the module
Do not disassemble or modify the modules. Doing so could cause trouble, erroneous
operation, injury, or fire
Switch all phases of the external power supply off before mounting or removing the module. If
ou do not switch off the external power supply it will cause failure or malfunction of the
module
