SAFETY PRECAUTIONS

(Be sure to read these instructions before use.)

Before using the product, read this and relevant manuals carefully and handle the product correctly with full attention to safety.

In this manual, SAFETY PRECAUTIONS are classified into 2 levels: "DANGER" and "CAUTION".

DANGER

CAUTION

Under some circumstances, failure to observe the CAUTION level instructions may also lead to serious results. Be sure to observe the instructions of both levels to ensure the safety.

Please keep this manual in a safe place for future reference and also pass this manual on to the end user.

Indicates that incorrect handling may cause hazardous conditions, resulting in death or severe injury.

Indicates that incorrect handling may cause hazardous conditions, resulting in medium or slight personal injury or physical damage.

[DESIGN PRECAUTIONS]

DANGER

Create a safety circuit outside the programmable controller to ensure the whole system will operate safely even if an external power failure or a programmable controller failure occurs. Otherwise, incorrect output or malfunction may cause an accident. (1) For an emergency stop circuit, protection circuit and interlock circuit that is designed for

incompatible actions such as forward/reverse rotation or for damage prevention such as the upper/lower limit setting in positioning, any of them must be created outside the programmable controller. Install the emergency stop switch outsid the controlpanel so that workers can operate it easily.

(2) When the programmable controller detects the following error conditions, it stops the operation

and turn off all the outputs.

• The overcurrent protection device or overvoltage protection device of the power supply module is activated.

• The programmable controller CPU detects an error such as a watchdog timer error by the self-diagnostics function.

In the case of an error of a part such as an I/O control part that cannot be detected by the programmable controller CPU, all the outputs may turn on.In order to make all machines operate safely in such a case, set up a fail-safe circuit or a specific mechanism outside the programmable controller. For a fail-safe circuit example, refer to "LOADING AND INSTALLATION" in this manual.

(3) Depending on the failure of the output module's relay or transistor, the output status may remain

ON or OFF incorrectly. For output signals that may lead to a serious accident, create an external monitoring circuit.

[DESIGN PRECAUTIONS]

DANGER

If load current more than the rating or overcurrent due to a short circuit in the load has flowed in the output module for a long time, it may cause a fire and smoke. as a fuse.

Design a circuit so that the external power will be supplied after power-up of the programmable controller. Activating the external power supply prior to the programmable controller may result in an accident due to incorrect output or malfunction.

For the operation status of each station at a communication error in data link, refer to the respective data link manual. The communication error may result in an accident due to incorrect output or malfunction.

When controlling a running programmable controller (data modification) by connecting a peripheral device to the CPU module or a PC to a special function module, create an interlock circuit on sequence programs so that the whole system functions safely all the time. Also, before performing any other controls (e.g. program modification, operating status change (status control)), read the manual carefully and ensure the safety. In these controls, especially the one from an external device to a programmable controller in a remote location, some programmable controller side problem may not be resolved immediately due to failure of data communications. To prevent this, create an interlock circuit on sequence programs and establish corrective procedures for communication failure between the external device and the programmable controller CPU.

Provide an external safety device such

When setting up the system, do not allow any empty slot on the base unit. If any slot is left empty, be sure to use a blank cover (A1SG60) or a dummy module (A1SG62) for it. When using the extension base unit, A1S52B(S1), A1S55B(S1) or A1S58B(S1), attach the included dustproof cover to the module in slot 0. Otherwise, internal parts of the module may be flied in the short circuit test or when an overcurrent or overvoltage is accidentally applied to the external I/O section.

[DESIGN PRECAUTIONS]

CAUTION

Do not install the control lines or communication cables together with the main circuit or power lines, or bring them close to each other. Keep a distance of 100mm (3.94inch) or more between them. Failure to do so may cause malfunctions due to noise.

When an output module is used to control the lamp load, heater, solenoid valve, etc., a large current (ten times larger than the normal one) may flow at the time that the output status changes from OFF to ON. Take some preventive measures such as replacing the output module with the one of a suitable current rating.

[INSTALLATION PRECAUTIONS]

CAUTION

Use the programmable controller under the environment specified in the user's manual. Otherwise, it may cause electric shocks, fires, malfunctions, product deterioration or damage.

Insert the module fixing projection into the fixing hole in the base unit and then tighten the module fixing screw within the specified torque. When no screw is tightened, even if the module is installed correctly, it may cause malfunctions, a failure or a drop of the module. Tightening the screw excessively may damage the screw and/or the module, resulting in a drop of the module, a short circuit or malfunctions.

Connect the extension cable to the connector of the base unit or module. Check for incomplete connection after installing it. Poor electrical contact may cause incorrect inputs and/or outputs.

Insert the memory cassette and fully press it to the memory cassette connector. Check for incomplete connection after installing it. Poor electrical contact may cause malfunctions.

Be sure to shut off all phases of the external power supply used by the system before mounting or removing the module. Failure to do so may damage the module.

Do not directly touch the conductive part or electronic components of the module. Doing so may cause malfunctions or a failure of the module.

[WIRING PRECAUTIONS]

DANGER

Be sure to shut off all phases of the external power supply used by the system before wiring. Failure to do so may result in an electric shock or damage of the product.

Before energizing and operating the system after wiring, be sure to attach the terminal cover supplied with the product. Failure to do so may cause an electric shock.

CAUTION

Ground the FG and LG terminals correctly. Failure to do so may cause an electric shock or malfunctions.

Wire the module correctly after confirming the rated voltage and terminal layout. Connecting a power supply of a different voltage rating or incorrect wiring may cause a fire or failure.

Do not connect multiple power supply modules to one module in parallel. The power supply modules may be heated, resulting in a fire or failure.

Press, crimp or properly solder the connector for external connection with the specified tool. Incomplete connection may cause a short circuit, fire or malfunctions.

Tighten terminal screws within the specified torque range. If the screw is too loose, it may cause a short circuit, fire or malfunctions. Tightening the screw excessively may damage the screw and/or the module, resulting in a drop of the module, a short circuit or malfunctions.

Carefully prevent foreign matter such as dust or wire chips from entering the module. Failure to do so may cause a fire, failure or malfunctions.

Install our programmable controller in a control panel for use. Wire the main power supply to the power supply module installed in a control panel through a distribution terminal block. Furthermore, the wiring and replacement of a power supply module have to be performed by a maintenance worker who acquainted with shock protection. (For the wiring methods, refer to Section 8.7.)

USER PRECAUTIONS

Precautions when using the AnS series

For a new CPU module, which has never used before, the contents of built-in RAM and device data are undefined. Make sure to clear the built-in RAM memory (PLC memory all clear) in the CPU module by peripheral devices and operate latch clear by RUN/STOP key switches.

Precautions for battery

(1) The operation after a battery is unmounted and the programmable controller is stored.

When reoperating after a battery is uncounted and the programmable controller is stored, the contents of built-in RAM and device data may be undefined. For this reason, make sure to clear the built-in RAM memory (PLC memory all clear) in the CPU module by peripheral devices and operate latch clear by RUN/STOP key

switches before start the operation again. After the built-in RAM clear and latch clear of the CPU module, write the backed-up memory contents to the CPU module before saving.

(2) The operation after excess of a battery life

If a battery exceeded its guaranteed life is stored and reoperated, the contents of built-in RAM and device data may be undefined. For this reason, make sure to clear the built-in RAM memory (PLC memory all clear) in the CPU module by peripheral devices and operate latch clear by RUN/STOP key

switches before start the operation again. After the built-in RAM clear and latch clear of the CPU module, write the backed-up memory contents to the CPU module before saving.

POINT

Make sure to back up each memory contents before storing the programmable controller.

* Refer to the following manuals for details of built-in RAM clear (PLC memory all clear) by periph-

eral devices.

1. OVERVIEW

1 OVERVIEW

This user's manual describes the functions, specification, and handling of the A1SJHCPU general purpose programmable controller (abbreviated as A1SJHCPU from here on), A1SJHCPU-S8 general purpose programmable controller (abbreviated as A1SJHCPUS8), A1SHCPU general purpose PLC (abbreviated as A1SHCPU), A2SHCPU general purpose PLC (abbreviated as A2SHCPU), and A2SHCPU-S1 general purpose PLC (abbreviated as A2SHCPU-S1).

A1SHCPU and A1SJHCPU are grouped as A1SHCPU, unless there is necessity to identify each model.

Also, A1SHCPU, A2SHCPU and A2SHCPU-S1 are grouped as AnSHCPU, unless there is necessity to identify each model.

The AnSHCPU is a compact-type building block programmable controller. The model is one third the size of the conventional building block type programmable controller, and allows easy operation in spite of its small size.

Sequence programs that have been created for the existing A0J2CPU, A0J2HCPU and

A NCPU models can be used by changing the CPU module type specification for the

program. Moreover, since modules for use with A NCPU can be used by installing them

on an extension base unit for A NCPU use, it is possible to extend the functions of an AnSCPU.

This user's manual refers to peripheral devices by using the following abbreviations.

A6GPP, A6PHP, PC/AT (started up with SW IVD-GPPA)

......................................................... Abbreviated as "GPP function".

A7PUS, A8PUE .............................. Abbreviated as "PU".

1. OVERVIEW

1.1 Features

(1) High-speed operation processing speed

Compared to the conventional A1SCPU, the A1SHCPU is three times and A2SHCPU (S1) is four times faster in the operation processing speed, respectively.

Item A1SHCPU A2SHCPU(S1) A1SCPU

Operation processing speed

*1 I/O processing: Refresh and LD instruction

0.33 s 0.25 s 1 s

(2) Addition of new dedicated instructions

The CC-Link dedicated instructions (8 instructions) have been added, making the operation even easier.

(3) Increased number of I/O device points

The actual number of I/O points is the same as the AnS series, but each CPU has 2048 points (X/Y0 to X/Y7FF) of I/O devices. The added I/O device can be used as the MELSECNET (/B), MELSECNET/MINI-S3, or CC-Link.

(4) Increased file register R capacity

The capacity is now max. 8192 points (R0 to R8191), which doubled the AnS series' 4096 points (R0 to R4095).

(5) Increased memory capacity (Increased number of comment points)

The A1SHCPU has 64 k bytes, which doubled the A1SCPU's 32 k bytes. This increased the number of comment points stored in the CPU module 3648 points in comparison to the 1600 points in A1SCPU.

(6) Full compatibility with A1S(S1)/A2SCPU(S1)

Because there is full compatibility of the functions and instructions with A1S(S1)/ A2SCPU(S1), all software packages can be used. In addition, power supply module, base unit, and I/O modules can be used.

(7) Compact size

The appearance of the AnSHCPU system with one power supply module, one CPU, and eight 16-point I/O modules for use with AnS mounted to the main base unit are: 430mm (16.9in.) (W); 130mm (5.12in.) (H); and 110mm (4.33in.) (D).

(8) Max. 8 k/14 k steps of program

An A1SHCPU allows the creation of a sequence program up to 8k steps, an A2SHCPU(S1) allows up to 14k steps. In addition, microcomputer programs and utility programs created by the user can be used.

1 - 2

Page 20

OVERVIEW1.

(9) SFC language compatible

An AnSCPU contains a microcomputer program area, so an SFC program can be used.

(10) Two extension connectors, on the right and left sides. (A1SHCPU,A2SHCPU(S1))

In order to facilitate wiring wherever the extension base unit is installed, extension connectors are provided at both left and right sides of the AnSHCPU and extension cables that suit the requirements imposed by different mounting locations are available. * A1SJHCPU(S8) on the right side only

(11) Use either screws or DIN rail for panel installations

The AnS base unit is provided both with screw holes and, on its rear face, the fixture for mounting it to a DIN rail.

(12) Easy-to-see terminal block symbol sheet

• A terminal block symbol sheet is attached to the front of AnS I/O modules. AnSHCPU writes I/O device numbers, connector numbers, etc. on one side of the sheet.

• Terminal symbols for 16 I/O signals can be written on the other side.

(13) A N, A A-series I/O module and special function module compatible

By connecting an A N, A A-series extension base unit, A N, A A I/O modules or special function modules can be used.

(14) Same programming environment as other MELSEC-A CPU modules

A sequence program can be created using the peripheral device currently used for other MELSEC-A CPU modules. For details on the applicable peripheral devices, refer to Section 2.2 "Precautions when Configuring the System".

4.1.1 Overview of operation processing

The following shows an overview of processing which begins with a CPU module poweron to execute the sequence program. CPU modules processing may be categorized roughly into the following four kinds:

(1) Initial processing

This is a preprocess to execute sequence operations, and is performed only once upon power-on or reset. (a) Resets the I/O module and initialize it.

(b) Initializes the range of data memory for which latch is not set up (sets the bit

device to OFF and the word device to 0).

number or the position of installation on the extension base module.

(d) Executes the self-diagnostics check for the parameter setting and the operation

circuit. (Refer to Section 4.1.4.)

(e) If the AnSHCPU is used in the master station of an MELSECNET(II)

MELSECNET/B, data link operation begins after setting the link parameter data in the data link module.

(2) Refresh processing of I/O module

Executes the refresh processing of I/O module. (Refer to the ACPU/QCPU-A (A mode) Programming Manual (Fundamentals).)

(3) Operation processing of a sequence program

Executes the sequence program from step 0 to the END instruction written in the programmable controller CPU.

(4) END processing

This is a post-process that finishes one cycle of operation processing of the sequence program and returns the execution of the sequence program to the step 0. (a) Executes self-diagnostics checks, such as a fuse blown, an I/O module verify,

and a low battery. (Refer to Section 4.1.4.)

(b) Updates the current value of the timer, sets the contact ON/OFF, updates the

current value of the counter and sets the contact to ON. (Refer to the ACPU/QCPU-A (A mode) Programming Manual (Fundamentals).)

computer link module (e.g. A1SJ71UC24-R2) when there is a data read or write request from the computer link module.

CPU MODULE4.

(d) Executes the refresh processing when there is a refresh request from the

network module or link module. Note that the AnSHCPU can enable and disable execution of link refresh by turning ON/OFF M9053 and by issuing DI/EI instructions.

(e) When the trace point setting of sampling trace is set for each scan (after END

instruction execution), stores the device status for which it is setup into the sampling trace area.

POINT

When executing the FROM/TO instruction for the special function module frequently in short scan time, it may cause an operation error in the target special function module. When executing the FROM/TO instruction, match the processing time and conversion time for the special function module using timer or constant scan function.

4.1.2 Operation processing of RUN, STOP and PAUSE

The programmable controller CPU can be operated in the RUN, STOP and PAUSE as described below. Operation processing of programmable controller CPU in each operation status is explained.

(1) Operation processing in RUN

(a) RUN status means that the sequence program operation is repeated as step 0

END (FEND) instruction 0.

(b) When entering the RUN status, outputs the stored output status at STOP

because of setting the output mode as STOP RUN in the parameters.

program operation is usually one to three seconds, although it may vary depending on the system configuration.

(2) Operation processing in STOP

(a) STOP status means that the sequence program operation is canceled due to the

RUN/STOP key switch, STOP instruction, or the remote STOP. (Refer to Section

4.3.)

(b) When entering the STOP status, stores the output status and sets all output

points to OFF. Data memories except for output (Y) are retained.

(3) Operation processing in PAUSE

(a) PAUSE status means that the sequence program operation is canceled retaining

output and data memories. (Refer to Section 4.3.)

4.1.3 Operation processing upon instantaneous power failure

The programmable controller CPU detects a momentary power failure when input power voltage supplied to the power supply module becomes lower than the specified range. When the programmable controller CPU detects an instantaneous power failure, the following operation processing is performed.

(1) When an instantaneous power failure shorter than allowable momentary power

failure period occurred: (a) When an instantaneous power failure occurred, the operation processing is

interrupted while the output status is retained.

(b) When the instantaneous power failure is reset, the operation processing will be

continued.

interrupted, measurement of the watchdog timer (WDT) continues. For instance, in the case that WDT is 200ms and the scan time is 190ms, if an instantaneous power failure of 15ms occurs, it causes the watchdog timer error.

4.1.4 Self-diagnostics function

Self-diagnosis is a function that a CPU module diagnoses itself for the presence of any abnormalities.

(1) While turning on the programmable controller power or when an error occurred in the

PLC RUN, the error is detected and displayed, and the operation is stopped by the self-diagnostics function, which the CPU module performs, to prevent programmable controller malfunctions and give preventive maintenance.

(2) The CPU module stores the error occurred last to a special register D9008 as an

error code.

(3) The following shows contents of the error information. (The error which occurred

last):

(a) The time and date of error occurrences.................... Year, month, day, hour,

(b) Error Code................................................................ The content of the special

(d) Error step and error module installation address.......The content of the special

minute, second (Clock data)

(4) When detecting an error by self-diagnosis, AnSHCPU takes action in the following

modes:

• Mode wherein the programmable controller operation is stopped

• Mode wherein the programmable controller operation is continued In addition, some errors can be skipped or stopped by setting parameters. (a) When an operation stop error is detected by the self-diagnosis, the AnSHCPU

stops the operation at error detection, and sets the all outputs(Y) to OFF.

(b) When an error of operation continued is detected, the only part of the program

with the error is not executed while the other part is executed. Also, in the case of module verify error, the operation is continued using the I/O

address prior to the error. Since error occurrence and error contents are stored in the special relay (M) and special register (D) at error detection, use in the program for preventing any malfunctions of the programmable controller or mechanical system especially in mode wherein the programmable controller operation is continued.

The next page shows error descriptions detected by the self-diagnosis.

(1) As to the LED indication, the order of priority of the LED indication can

be changed if CPU module is in the operation mode. (Error codes are stored in the special register.)

(2) When the special relay M9084 is ON, checking on fuse blown, I/O

verification and the battery are not performed. (Error codes are not stored in the special register.)

4.5.4 Latch clear operation

When performing latch clear by the RUN/STOP key switch, follow the procedures below. When the latch clear is performed, the device data in the non-latched range is also cleared.

(1) Switch the RUN/STOP key switch a few times (three or four times) from "STOP" to

"L.CLR", and then "RUN" LED turns flicker at high speed (about 0.2s ON, 0.2s OFF). If the "RUN" LED turns flicker at high speed, a latch clear is ready.

(2) After the "RUN"LED flickers at high speed, switch the RUN/STOP key switch from

"STOP" to "L.CLR" again, and then the latch clear is all prepared and "RUN" LED turns off. In the case of cancelling the latch clear operation halfway, switch the RUN/STOP key switch to "RUN" to lead the CPU module to RUN status, or switch to "RESET" to lead it to reset status.

REMARK

The latch clear can also be performed by the operation of GPP function. For instance, latch clear by A6GPP can be performed by "Device memory all clear" of the PLC mode test function. For the operation method, refer to the operating manual for GPP functions.

POWER SUPPLY MODULE5.

POINT

*1 Overcurrent protection

The overcurrent proctection device shuts off the 5VDC and/or 24VDC circuit(s) and stops the system if the current exceeding the specified value flows in the circuit(s). As this results in voltage drop, the power supply module LED turns OFF or is dimly ON. After that, eliminate the causes of overcurrent, e.g., insufficient current capacity and short-circuit, and then start the system. When the current value has reached the normal value, the initial start up of the system will be performed.

*2 Overvoltage protection

The overvoltage protection shuts off the 5VDC circuit and stops the system if the overvoltage of 5.5 to 6.5V is applied to the circuit. The power supply module LED turns OFF. When restarting the system, power OFF and ON the input power supply, and the initial start up of the system will be performed.If the system is not booted and the LED remains off, this means that the power supply module has to be replaced.

*3 Allowable momentary power failure period

The programmable controller CPU allowable momentary power failure period varies with the power supply module used. In case of the A1S63P power supply module, the allowable momentary power failure period is defined as the time from when the primary side of the stabilized power supply for supplying 24VDC to the A1S63P is turned OFF until when the voltage (secondary side) has dropped from 24VDC to the specified voltage (15.6VDC) or less.

*4 Inrush current

If power is reapplied immediately after power OFF (within 5 seconds), an inrush current exceeding the specified value may flow (for 2ms or less). Therefore, make sure to re-power ON the module 5seconds after power off. When selecting a fuse or breaker for an external circuit, consider the above as well as meltdown and detection characteristics.

5. POWER SUPPLY MODULE

5.1.1 Power supply module selection

Power supply module is selected based on to the total current consumption of the I/O module, special function module and peripheral devices to which power is supplied by the subject power supply module. When extension base unit A1S52B(S1), A1S55B(S1), A1S58B(S1), A52B, A55B, A58B is used, take into consideration that the power to the module is supplied by the power supply module of the main base. For 5VDC current consumption of I/O modules, special function modules and peripheral devices, refer to Section 2.3.

(1) Power supply module selection when extension base unit A1S52B(S1), A1S55B(S1),

A1S58B(S1), A52B, A55B, A58B is used When extension base unit A1S52B(S1), A1S55B(S1), A1S58B(S1), A52B, A55B, A58B is used, 5VDC power supply is supplied from the power supply module of the main base unit via extension cable. Thus, when one of these units is used, be careful with the following: (a) Select a 5VDC power supply module of the main base unit with sufficient

capacity to supply 5VDC current consumed by A1S52B(S1), A1S55B(S1), A1S58B(S1), A52B, A55B, A58B.

Example) If 5VDC current consumption on the main base unit is 3A and 5VDC

current consumption on the A1S55B is 1A, then, the power supply module installed to the main base unit must be A1S61P(5VDC 5A).

(b) Since the power to A1S52B(S1), A1S55B(S1), A1S58B(S1), A52B, A55B, A58B

is supplied via extension cable, a voltage drop occurs through the cable. It is necessary to select a power supply module and cable with proper length so that

4.75VDC or more is available at the receiving port. For the details of voltage drop, refer to Section 6.1.3, the applicable standards of extension base units.

6.1.3 Application standards of extension base units (A1S52B(S1), A1S55B(S1), A1S58B(S1), A52B, A55B, A58B)

When using the A1S52B(S1), A1S55B(S1), A1S58B(S1), A52B, A55B or A58B extension base unit, make sure that the voltage of the receiving port (the module installed in the last slot of the extension base unit) is 4.75V or more. Since the power supply module on the main base unit supplies 5VDC to the A1S52B(S1), A1S55B(S1), A1S58B(S1), A52B, A55B or A58B extension base unit, a voltage drop occurs through the base unit and extension cable. If the specified voltage is not supplied at the receiving port, incorrect input or output may result. If the voltage at the receiving port is less than 4.75V, replace the extension base unit with the A1S65B(S1), A1S68B(S1), A62B, A65B or A68B that has a power supply.

(1) Selection condition

Receiving voltage of the module installed in the last slot of the A1S52B(S1), A1S55B(S1), A1S58B(S1), A52B, A55B or A58B extension base unit is 4.75V or more. The output voltage of the power supply module is set to 5.1V or more. Thus, a voltage drop of 0.35V or less allows use of the module.

(4) Calculation examples

(a) Calculation of voltage drop on the main base unit

K= 0.007 {0.3 + 0.05 (9 + 8 + 7 + 6 + 5 + 4 + 3 + 2) + (0.27 8) 9} = 0.15358

(b) Calculation of voltage drop on the extension base unit

Z = 0.006 0.27 (8+7+6+5+4+3+2+1) = 0.05832

C = 0.021 (0.27 8) = 0.04536

(d) Verification of the receiving port voltage

5.1-0.15358-0.05832-0.04536=4.84274(V)

Since the receiving port voltage is more than 4.75V, the above system is usable.

(5) To reduce the voltage drop

The following methods are effective to reduce the voltage drop. (a) Change the installing position of the module

Install the modules with high current consumption in order starting from slot 0 of the main base unit. Install modules with low current consumption to the extension base unit.

(b) Connect the base units in series

By connecting base units in series (connecting the extension cable to the left side of the main base unit. Refer to this section (2), the voltage drop on the main base unit can be ignored. If the extension cable is long, however, the voltage drop through the cable may be larger than that on the main base unit. Therefore, calculate the voltage drop according to (3).

The shorter the extension cable is, the smaller the resistive value and the voltage drop become. Use the extension cable as short as possible.

* When writing a program to the A1SNMCA-2KE, set the parameter for main

sequence program capacity to 2k steps or less. If the program is written with setting the main sequence program capacity to 3k steps or more, it cannot properly work. Comparing between the AnSHCPU and a peripheral device will result in a mismatch.

7.1.2 Handling precautions

This section explains the specifications of the memory cassette, the handling precautions and the installation and removal procedures.

(1) Since the memory cassette and pin connector are made of resin, do not drop them or

apply heavy impact to them.

(2) Do not remove the printed-circuit board of memory cassette from the case. Doing so

could give damage to the module.

(3) Carefully prevent foreign matter such as wire chips from entering the inside of the

memory cassette. If it does get inside the module, remove it immediately.

(4) When installing the memory cassette into the CPU module, fully press it to the

connector.

(5) Do not place the memory cassette on a metal object where current is or can be

leaked, or materials like wood, plastic, vinyl, fibers, electric wires or paper where static electricity is charged.

(6) Do not touch the lead of the memory. This may damage the memory.

(7) Do not touch the CPU connector of the memory cassette. Doing so may cause poor

contact.

POINT

(1) Before installing the memory cassette to or removing it from the CPU module,

make sure that the power is OFF. Installing or removing the memory cassette with power ON destroys its memory.

(2) Install the memory cassette and turn on the power supply of CPU module.

RAM memory built-in CPU module (parameter, T/C setting value, main program) is overwritten. If the RAM memory is needed, back up the data using a peripheral device before installing the memory cassette.

7.1.3 Installation and removal of memory cassette

CAUTION

Insert the memory cassette and fully press it into the memory cassette connector. Check for incomplete connection after installing it. Poor electrical contact may cause malfunctions.

The installation/removal method of the memory cassette is common in all AnSHCPU models, but the installation position is unique to each model.

Memory cassette installation position: A1SHCPU, A2SHCPU(S1)...........Left side

A1SJHCPU(S8)..........Front

(1) Installation of the memory cassette

(a) Facing the model name side of the memory cassette to the operator with the

model name shown on the top, insert it into the applied part of CPU module until a click is heard (a tab is engaged).

(b) Check that the hooks on the top and bottom of the memory cassette are

engaged with the catches of the CPU module. (If the memory cassette is not installed correctly, the front cover of the CPU module will not be closed.)
