 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".

Indicates that incorrect handling may cause hazardous

DANGER

conditions, resulting in death or severe injury.

CAUTION

Under some circumstances, failure to observe the 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 minor or moderate injury and/or property damage.

CAUTION level

[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.

A-1

[DESIGN PRECAUTIONS]

DANGER

(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.

Refer to "LOADING AND INSTALLATION" in this manual for example fail safe circuits.

(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.  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. Provide an external safety device such 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.

A-2

[DESIGN PRECAUTIONS]

DANGER

 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.

 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 external I/O section.

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.

 If having read register R outside the allowable range with the MOV

instruction, the file register data will be FFFF

H. Using this as it is may cause

malfunctions. Pay attention not to use any out-of-range file register when designing sequence programs. For instruction details, refer to the programming manual.

 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.

A-3

[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 mounting 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 the cable for incomplete connection after connecting it. Poor electrical contact may cause incorrect inputs and/or outputs.

 Insert the memory card and fully press it to the memory card 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.

A-4

[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

 Always ground the FG and LG terminals to the protective ground conductor.

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. If too tight, it may damage the screw and/or the module, resulting in 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 Type Q2AS(H)CPU(S1) User’s Manual.)

A-5

[STARTUP AND MAINTENANCE PRECAUTIONS]

DANGER

 Do not touch any terminal during power distribution.

Doing so may cause an electric shock.

 Properly connect batteries. Do not charge, disassemble, heat or throw them

into the fire and do not make them short-circuited and soldered. Incorrect battery handling may cause personal injuries or a fire due to exothermic heat, burst and/or ignition.

 Be sure to shut off all phases of the external power supply used by the

system before cleaning or retightening the terminal screws or module mounting screws. Failure to do so may result in an electric shock. If they are too loose, it may cause a short circuit or malfunctions. If too tight, it may cause damage to the screws and/or module, resulting in an accidental drop of the module, short circuit or malfunctions.

CAUTION

 When performing online operations (especially, program modification, forced

output or operating status change) by connecting a peripheral device to the running CPU module, read the manual carefully and ensure the safety. Incorrect operation will cause mechanical damage or accidents.

 Do not disassemble or modify each of modules.

Doing so may cause failure, malfunctions, personal injuries and/or a fire.

 When using a wireless communication device such as a mobile phone, keep

a distance of 25cm (9.84inch) or more from the programmable controller in all directions. Failure to do so 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 result in failure or malfunctions of the module.

 Do not drop or apply any impact to the battery.

Doing so may damage the battery, resulting in electrolyte spillage inside the battery. If any impact has been applied, discard the battery and never use it.

 Do not install/remove the terminal block more than 50 times after the first use

of the product. (IEC 61131-2 compliant)

 Before handling modules, touch a grounded metal object to discharge the

static electricity from the human body. Failure to do so may cause failure or malfunctions of the module.

3. EMC DIRECTIVES AND LOW VOLTAGE DIRECTIVES

The products sold in the European countries have been required by law to comply with the EMC Directives and Low Voltage Directives of the EU Directives since 1996 and 1997, respectively. The manufacturers must confirm by self-declaration that their products meet the requirements of these directives, and put the CE mark on the products.

3.1 Requirements for Compliance with EMC Directives

The EMC Directives specifies emission and immunity criteria and requires the products to meet both of them, i.e., not to emit excessive electromagnetic interference (emission): to be immune to electromagnetic interference outside (immunity). Guidelines for complying the machinery including MELSEC-QnA series programmable controller with the EMC Directives are provided in Section 3.1.1 to

3.1.6 below. The guidelines are created based on the requirements of the regulations and relevant standards, however, they do not guarantee that the machinery constructed according to them will not comply with the Directives. Therefore, the manufacturer of the machinery must finally determine how to make it comply with the EMC Directives: if it is actually compliant with the EMC Directives.

3.1.2 Installation instructions for EMC Directive

The programmable controller is open equipment and must be installed within a control cabinet for use.* This not only ensures safety but also ensues effective shielding of programmable controller-generated electromagnetic noise. * : Also, each network remote station needs to be installed inside the control

panel. However, the waterproof type remote station can be installed outside the control panel.

(1) Control cabinet

(a) Use a conductive control cabinet. (b) When attaching the control cabinet's top plate or base plate, mask

painting and weld so that good surface contact can be made between the cabinet and plate.

(c) To ensure good electrical contact with the control cabinet, mask the paint

on the installation bolts of the inner plate in the control cabinet so that contact between surfaces can be ensured over the widest possible area.

(d) Earth the control cabinet with a thick wire so that a low impedance

connection to ground can be ensured even at high frequencies.

(e) Holes made in the control cabinet must be 10 cm (3.94 in.) diameter or

less. If the holes are 10 cm (3.94 in.) or larger, radio frequency noise may be emitted.

(f) Lock the control panel so that only those who are trained and have

acquiredenough knowledge of electric facilities can open the control panel.

(2) Connection of power and earth wires

Earthing and power supply wires for the programmable controller system must be connected as described below. (a) Provide an earthing point near the power supply module. Earth the

power supply's LG and FG terminals (LG: Line Ground, FG: Frame Ground) with the thickest and shortest wire possible. (The wire length must be 30 cm (11.81 in.) or shorter.) The LG and FG terminals function is to pass the noise generated in the programmable controller system to the ground, so an impedance that is as low as possible must be ensured. In addition, make sure to wire the ground cable short as the wires are used to relieve the noise, the wire itself carries large noise content and thus short wiring means that the wire is prevented from acting as an antenna.

(b) The earth wire led from the earthing point must be twisted with the power

supply wires. By twisting with the earthing wire, noise flowing from the power supply wires can be relieved to the earthing. However, if a filter is installed on the power supply wires, the wires and the earthing wire may not need to be twisted.

3.1.3 Cables

The cables pulled out of the control panel contain a high frequency noise component. On the outside of the control panel, therefore, they serve as antennas to emit noise. Ensure to use shielded cables for the cables, which are connected to the I/O modules, special modules and those pulled out to outside of the control panel. Mounting ferrite core is not required except some types of CPU however, noise emanated via the cable can be restrained using it. The use of a shielded cable also increases noise resistance. The signal lines (including common line) connected to the programmable controller input/output modules and intelligent modules use shielded cables to assure noise resistance, as a condition, standardized on EN61131-2/A12 (2000). If a shielded cable is not used or not earthed correctly, the noise resistance will be less than the rated value

(1) Earthing of shielded of cables

(a) Earth the shield of the shielded cable as near the unit as possible taking

care so that the earthed cables are not induced electromagnetically by the cable to be earthed.

(b) Take appropriate measures so that the shield section of the shielded

cable from which the outer cover was partly removed for exposure is earthed to the control panel on an increased contact surface. A clamp may also be used as shown in the figure below. In this case, however, apply a cover to the painted inner wall surface of the control panel which comes in contact with the clamp.

Note) The method of earthing by soldering a wire onto the shield section of

the shielded cable as shown below is not recommended. The high frequency impedance will increase and the shield will be ineffective.

(2) MELSECNET (II) and MELSECNET/10 units

(a) Use a double-shielded coaxial cable for the MELSECNET unit which

uses coaxial cables. Noise in the range of 30 MHz or higher in radiation noise can be suppressed by the use of double-shielded coaxial cables (Mitsubishi Cable: 5C-2V-CCY). Earth the outer shield to the ground. The precautions on shielding to be followed are the same as those stated in item (1) above.

Earth this sectionShield

(b) Ensure to attach a ferrite core to the double-shielded coaxial cable

connected to the MELSECNET unit. In addition, position the ferrite core on each cable near the outlet of the control panel. TDK-make ZCAT3035 ferrite core is recommended.

(3) Ethernet module

Precautions to be followed when AUI cables and coaxial cables are used are described below. (a) Ensure to earth also the AUI cables connected to the 10BASE5

connectors of the A1SJ71QE71-B5. Because the AUI cable is of the shielded type, as shown in the figure below, partly remove the outer cover of it, and earth the exposed shield section to the ground on the widest contact surface.

(4) I/O and other communication cables

For the I/O signal lines (including common line) and other communication cables (RS-232, RS-422, etc), if extracted to the outside of the control panel, also ensure to earth the shield section of these lines and cables in the same manner as in item (1) above.

(a) Be sure to ground the cable shield that is connected to the CC-Link

module close to the exit of control panel or to any of the CC-Link stations within 30 cm (11.81 in.) from the module or stations. The CC-Link dedicated cable is a shielded cable. As shown in the illustration below, remove a portion of the outer covering and ground as large a surface area of the exposed shield part as possible.

(d) Power line connecting to the external power supply terminal (compliant

with I/O power port of CE standard) should be 30m (98.43 ft.) or less. Power line connecting to module power supply terminal (compliant with main power port of CE standard) should be 10m (32.81 ft.) or less.

(e) A power line connecting to the analog input of the following modules

should be 30cm or less.

• AJ65BT-64RD3

• AJ65BT-64RD4

• AJ65BT-68TD

(7) Measures against static electricity

When using an insulation displacement connector without connector cover, a connected cable for the connector is thin in applicable wire size and coating. Therefore, note that the module may cause an electric discharge failure. As measures against the failure, using pressure-displacement type connector whose applicable wire size is thick or soldering type connector is recommended.

3.1.4 Power supply module

The precautions required for each power supply module are described below. Always observe the items noted as precautions.

Model Precautions

A1S61PN, A1S62PN

A1S63P 1

Make sure to short and ground the LG and FG terminals. Use the 24VDC panel power equipment conforming to the EU Directive.

2

1: If sufficient filter circuitry is built into the 24 VDC external power supply

module, the noise generated by A1S63P will be absorbed by that filter circuit, so a line filter may not be required. Filtering circuitry of version F or later of A1S63P is improved so that a external line filter is not required.

2: To ensure the compliance with CE (EN6111-21/A11), make sure to short

the LG and FG terminals using a wire of 6 to 7cm.

3.1.5 Base unit

The following table shows models of base units that are compatible with EMC instructions.

Type Model name Applicability

Main base unit

A1S38HBEU Applicable A1S3

B, A1S38HB Not applicable

Extension base unit A1S5 B(S1), A1S6 B(S1) Applicable

3.1.6 Ferrite core

Use of ferrite cores is effective in reducing the conduction noise in the band of about 10 MHz and radiated noise in 30 to 100 MHz band. It is recommended to attach ferrite cores when the shield of the shielded cable coming out of control panel does not work effectively, or when emission of the conduction noise from the power line has to be suppressed.*1 The ferrite cores used in our tests are TDK's ZCAT3035. It should be noted that the ferrite cores should be fitted to the cables in the position immediately before they are pulled out of the enclosure. If the fitting position is improper, the ferrite will not produce any effect.

1:To response with CE (EN61131-2/A12), make sure to mount 2 or more

ferrite cores onto the power supply line. The mounting position should be as near the power supply module as possible. Ferrite core Type: ZCAT2235-1030A (TDK ferrite core)

11

3.1.7 Noise filter (power supply line filter)

A noise filter is a component which has an effect on conducted noise. With the exception of some models, it is not required to fit the noise filter to the power supply line, but fitting it can further suppress noise. (The noise filter has the effect of reducing conducted noise of 10 M Hz or less.) Use any of the following noise filters (double

type filters) or equivalent.

Model name FN343-3/01 FN660-6/06 ZHC2203-11

Manufacturer SCHAFFNER SCHAFFNER TDK

Rated current 3 A 6 A 3 A

Rated voltage 250 V

The precautions required when installing a noise filter are described below.

(1) Do not bundle the wires on the input side and output side of the noise filter.

When bundled, the output side noise will be induced into the input side wires from which the noise was filtered.

3.2 Requirements for Compliance with Low Voltage Directives

The Low Voltage Directives apply to the electrical equipment operating from 50 to 1000VAC or 75 to 1500VDC; the manufacturer must ensure the adequate safety of the equipment. Guidelines for installation and wiring of MELSEC-QnA series programmable controller are provided in Section 3.2.1 to 3.2.7 for the purpose of compliance with the EMC Directives. The guidelines are created based on the requirements of the regulations and relevant standards, however, they do not guarantee that the machinery constructed according to them will comply with the Directives. Therefore, the manufacturer of the machinery must finally determine how to make it comply with the EMC Directives: if it is actually compliant with the EMC Directives.

3.2.1 Standard applied for MELSEC-QnA series programmable controller

The standard applied for MELSEC-QnA series programmable controller series is EN61010-1 safety of devices used in measurement rooms, control rooms, or laboratories.

For the modules which operate with the rated voltage of 50 VAC/75 VDC or above, we have developed new models that conform to the above standard. For the modules which operate with the rated voltage under 50 VAC/75 VDC, the conventional models can be used, because they are out of the low voltage directive application range.

3.2.2 Precautions when using the MELSEC-QnA series programmable controller

Module selection (1) Power module

For a power module with rated input voltage of 100/200 VAC, select a model in which the internal part between the first order and second order is intensively insulated, because it generates hazardous voltage (voltage of 42.4 V or more at the peak) area. For a power module with 24 VDC rated input, a conventional model can be used.

(2) I/O module

For I/O module with rated input voltage of 100/200 VAC, select a model in which the internal area between the first order and second order is intensively insulated, because it has hazardous voltage area. For I/O module with 24 VDC rated input, a conventional model can be used.

(3) CPU module, memory cassette, base unit

Conventional models can be used for these modules, because they only have a 5 VDC circuit inside.

(4) Special function module

Conventional models can be used for the special modules including analog module, network module, and positioning module, because the rated voltage is 24 VDC or smaller.

(5) Display device

Use the CE-marked product.

13

3.2.3 Power supply

The insulation specification of the power module was designed assuming installation category II. Be sure to use the installation category II power supply to the programmable controller. The installation category indicates the durability level against surge voltage generated by a thunderbolt. Category I has the lowest durability; category IV has the highest durability.

Category III Category II Category ICategory IV

Figure 1.: Installation Category

Category II indicates a power supply whose voltage has been reduced by two or more levels of isolating transformers from the public power distribution.

14

3.2.4 Control panel

Because the programmable controller is an open device (a device designed to be stored within another module), be sure to use it after storing in the control panel.

(1) Electrical shock prevention

In order to prevent persons who are not familiar with the electric facility such as the operators from electric shocks, the control panel must have the following functions:

(a) The control panel must be equipped with a lock so that only the personnel

who has studied about the electric facility and have enough knowledge can open it.

(b) The control panel must have a structure which automatically stops the

power supply when the box is opened.

(c) For electric shock protection, use IP20 or greater control panel.

(2) Dustproof and waterproof features

The control panel also has the dustproof and waterproof functions. Insufficient dustproof and waterproof features lower the insulation withstand voltage, resulting in insulation destruction. The insulation in our programmable controller is designed to cope with the pollution level 2, so use in an environment with pollution level 2 or below.

Pollution level 1: An environment where the air is dry and conductive dust

does not exist.

Pollution level 2: An environment where conductive dust

does not usually exist, but occasional temporary conductivity occurs due to the accumulated dust. Generally, this is the level for inside the control panel equivalent to IP54 in a control room or on the floor of a typical factory.

Pollution level 3: An environment where conductive dust exits and

conductivity may be generated due to the accumulated dust. An environment for a typical factory floor.

Pollution level 4: Continuous conductivity may occur due to rain, snow, etc.

An outdoor environment.

As shown above, the programmable controller can realize the pollution level 2

when stored in a control panel equivalent to IP54.

15

3.2.5 Module installation

(1) Installing modules contiguously

In Q2AS series programmable controllers, the left side of each I/O module is left open. When installing an I/O module to the base, do not make any open slots between any two modules. If there is an open slot on the left side of a module with 100/200 VAC rating, the printed board which contains the hazardous voltage circuit becomes bare. When it is unavoidable to make an open slot, be sure to install the blank module (A1SG60).

3.2.6 Grounding

There are two kinds of grounding terminals as shown below. Either grounding terminal must be used grounded. Be sure to ground the protective grounding for the safety reasons.

Protective grounding

: Maintains the safety of the programmable

controller and improves the noise resistance.

Functional grounding

: Improves the noise resistance.

3.2.7 External wiring

(1) Module power supply and external power supply

For the remote module which requires 24VDC as module power supply, the 5/12/24/48VDC I/O module, and the intelligent function module (special function module) which requires the external power supply, use the 5/12/24/48VDC circuit which is doubly insulated from the hazardous voltage circuit or use the power supply whose insulation is reinforced.

(2) External devices

When a device with a hazardous voltage circuit is externally connected to the programmable controller, use a model whose circuit section of the interface to the programmable controller is intensively insulated from the hazardous voltage circuit.

(3) Intensive insulation

Intensive insulation refers to the insulation with the dielectric withstand voltage shown in Table 1.

Table 1: Intensive Insulation Withstand Voltage

4. LOADING AND INSTALLATION

4.1 Installing the Module

4.1.1 Notes on handling the module

This section explains some notes on handling the CPU module, I/O module, special function module, power supply module, and base unit.

(1) Do not drop or allow any impact to the modules case, memory card, terminal

block cover, or pin connector.

(2) Do not remove the module printed wiring board from the case. Otherwise, a

malfunction may occur.

(3) Use caution to prevent foreign matter, such as wire chips, falling into the

module during wiring. If foreign matter enters the module, remove it.

(4) Use the fallowing torque range to tighten the module fixing screws and

terminal block screws:

Screw portion Tightening torque range

Module fixing screw (M4 screw) 78 to 118 Ncm

I/O module (M3.5 screw) 59 to 88 Ncm

Power supply module terminal screws (M3.5 screw) 59 to 78 Ncm

(5) Observe the following points when you are installing the DIN rail:

(a) Applicable DIN rail type (JIS C 2812)

TH35-7.5Fe TH35-7.5Al TH35-15Fe

(b) DIN rail installation screw interval

When you are using the TH35-7.5Fe or TH35-7.5Al DIN rail, tighten the DIN rail installation screw with a pitch of 200 mm (7.87 inch) or less to maintain the strength.

P

P=200 mm (7.87 inch) or less

(6) When installing the base unit to DIN rail in an environment with large

vibration, use a vibration-proofing bracket (A1S-PLT-D). Mounting the vibration-proofing bracket (A1S-PLT-D) enhances the resistance to vibration. Depending on the environment to set up the base unit, it is also recommended to fix the base unit to the control panel directly.

17

4.1.2 Installation environment

Avoid the following environment when you install the CPU system:

(1) A location in which the ambient temperature falls outside the range of 0 to

55 degrees Celsius.

(2) A location in which the ambient humidity falls outside the range of 10 to

90%RH.

(3) A location in which condensation may occur due to drastic changes in

temperature.

(4) A location in which corrosive gas or flammable gas exists.

(5) A location in which the system is easily exposed to conductive powder,

such as dust and iron filings, oil mist, salt, or organic solvent.

(6) A location exposed to direct sunlight.

(7) A location in which strong electrical or magnetic fields are generated.

(8) A location in which the module is exposed to direct vibration or impact.

4.2 Fail-Safe Circuit Concept

When the programmable controller is powered ON and then OFF, improper outputs may be generated temporarily depending on the delay time and start-up time differences between the programmable controller power supply and the external power supply for the control target (especially, DC).

For example, if the external power supply for the control target is powered ON and then the programmable controller is powered ON, the DC output module may generate incorrect outputs temporarily upon the programmable controller power-ON. Therefore, it is required to build the circuit that energizes the programmable controller by priority.

The external power failure or programmable controller failure may lead to the system error. In order to eliminate the possibility of the system error and ensure fail-safe operation, build the following circuit outside the programmable controller: emergency circuit, protection circuit and interlock circuit, as they could cause machine damages and accidents due to the abovementioned failures.

An example of system design, which is based on fail-safe concept, is provided on the next page.

21

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. Install the emergency stop switch outsaid the controlpanel so that workers can operation it easily. 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.

(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.

(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 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.

 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. Provide an external safety device such as a fuse.

22

DANGER

 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.

CAUTION

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.

 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 external I/O section.

 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 (3.9inch) 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 module with the one of a suitable current rating.

(2) Fail-safe measures to cover the possibility of programmable controller

failure Problems with a CPU module and memory can be detected by the self diagnostics function. However, problems with I/O control area may not be detected by the CPU module. In such cases, all I/O points turn ON or OFF depending on the problem, and normal operation and safety cannot be maintained. Though Mitsubishi programmable controllers are manufactured under strict quality control, they may fail or malfunction due to unspecified reasons. To prevent the whole system failure, machine breakdown, and accidents, build a fail-safe circuit outside the programmable controller.

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 lit. After that, eliminate the causes of overcurrent, e.g., insufficient current capacity and short circuit, and then start the system. When the current 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. This results in the power supply module LED turning 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 value (15.6VDC) or less.

*4: Inrush current

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

4.3.3 Wiring instructions

Instructions for wiring the power supply cable and I/O cable.

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

 Always ground the FG and LG terminals to the protective ground conductor.

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.
