[Design Precautions]

WARNING

● Configure safety circuits external to the programmable controller to ensure that the entire system operates safely even when a fault occurs in the external power supply or the programmable controller.

Failure to do so may result in an accident due to an incorrect output or malfunction.

(1) Emergency stop circuits, protection circuits, and protective interlock circuits for conflicting operations (such as forward/reverse rotations or upper/lower limit positioning) must be configured external to the programmable controller.

(2) When the programmable controller detects an abnormal condition, it stops the operation and all outputs are:

• Turned off if the overcurrent or overvoltage protection of the power supply module is activated.

• Held or turned off according to the parameter setting if the self-diagnostic function of the CPU module detects an error such as a watchdog timer error.

Also, all outputs may be turned on if an error occurs in a part, such as an I/O control part, where the CPU module cannot detect any error. To ensure safety operation in such a case, provide a safety mechanism or a fail-safe circuit external to the programmable controller. For a fail-safe circuit example, refer to the "GENERAL SAFETY REQUIREMENTS" chapter in the Safety

Guidelines included with the CPU module or head module.

(3) Outputs may remain on or off due to a failure of a component such as a transistor in an output circuit. Configure an external circuit for monitoring output signals that could cause a serious accident.

● In an output circuit, when a load current exceeding the rated current or an overcurrent caused by a load short-circuit flows for a long time, it may cause smoke and fire. To prevent this, configure an external safety circuit, such as a fuse.

● Configure a circuit so that the programmable controller is turned on first and then the external power supply. If the external power supply is turned on first, an accident may occur due to an incorrect output or malfunction.

● For the operating status of each station after a communication failure, refer to relevant manuals for each network. Failure to do so may result in an accident due to an incorrect output or malfunction.

● When changing data from a peripheral device connected to the CPU module to the running programmable controller, configure an interlock circuit in the program to ensure that the entire system will always operate safely. For other forms of control (such as program modification or operating status change) of a running programmable controller, read the relevant manuals carefully and ensure that the operation is safe before proceeding. Especially, when a remote programmable controller is controlled by an external device, immediate action cannot be taken if a problem occurs in the programmable controller due to a communication failure. To prevent this, configure an interlock circuit in the program, and determine corrective actions to be taken between the external device and CPU module in case of a communication failure.

2

[Design Precautions]

CAUTION

● Do not install the control lines or communication cables together with the main circuit lines or power cables. Keep a distance of 100mm or more between them. Failure to do so may result in malfunction due to noise.

● During control of an inductive load such as a lamp, heater, or solenoid valve, a large current

(approximately ten times greater than normal) may flow when the output is turned from off to on.

Therefore, use a module that has a sufficient current rating.

● After the CPU module is powered on or is reset, the time taken to enter the RUN status varies depending on the system configuration, parameter settings, and/or program size. Design circuits so that the entire system will always operate safely, regardless of the time.

[Installation Precautions]

WARNING

● Shut off the external power supply (all phases) used in the system before mounting or removing a module. Failure to do so may result in electric shock or cause the module to fail or malfunction.

[Installation Precautions]

CAUTION

● Use the programmable controller in an environment that meets the general specifications in the Safety

Guidelines provided with the CPU module or head module. Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of the product.

● To interconnect modules, engage the respective connectors and securely lock the module joint levers until they click. Incorrect interconnection may cause malfunction, failure, or drop of the module.

● Do not directly touch any conductive parts and electronic components of the module. Doing so can cause malfunction or failure of the module.

[Wiring Precautions]

WARNING

● Shut off the external power supply (all phases) used in the system before wiring. Failure to do so may result in electric shock or cause the module to fail or malfunction.

● After installation and wiring, attach the included terminal cover to the module before turning it on for operation. Failure to do so may result in electric shock.

3

[Wiring Precautions]

CAUTION

● Individually ground the FG and LG terminals of the programmable controller with a ground resistance of 100 ohms or less. Failure to do so may result in electric shock or malfunction.

● Use applicable solderless terminals and tighten them within the specified torque range.

If any spade solderless terminal is used, it may be disconnected when a terminal block screw comes loose, resulting in failure.

● Check the rated voltage and terminal layout before wiring to the module, and connect the cables correctly.

Connecting a power supply with a different voltage rating or incorrect wiring may cause a fire or failure.

● Connectors for external devices must be crimped or pressed with the tool specified by the manufacturer, or must be correctly soldered. Incomplete connections may cause short circuit, fire, or malfunction.

● Securely connect the connector to the module.

● Do not install the control lines or communication cables together with the main circuit lines or power cables. Keep a distance of 100mm or more between them. Failure to do so may result in malfunction due to noise.

● Tighten the terminal block screws within the specified torque range. Undertightening can cause short circuit, fire, or malfunction. Overtightening can damage the screw and/or module, resulting in drop, short circuit, fire, or malfunction.

● When disconnecting the cable from the module, do not pull the cable by the cable part. For the cable with connector, hold the connector part of the cable.

For the cable connected to the terminal block, loosen the terminal screw.

Pulling the cable connected to the module may result in malfunction or damage to the module or cable.

● Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter can cause a fire, failure, or malfunction.

● A protective film is attached to the top of the module to prevent foreign matter, such as wire chips, from entering the module during wiring. Do not remove the film during wiring. Remove it for heat dissipation before system operation.

● Mitsubishi programmable controllers must be installed in control panels. Connect the main power supply to the power supply module in the control panel through a relay terminal block.

Wiring and replacement of a power supply module must be performed by qualified maintenance personnel with knowledge of protection against electric shock.

For wiring methods, refer to the MELSEC-L CPU Module User's Manual (Hardware Design,

Maintenance and Inspection).

[Startup and Maintenance Precautions]

WARNING

● Do not touch any terminal while power is on. Doing so will cause electric shock or malfunction.

● Correctly connect the battery connector. Do not charge, disassemble, heat, short-circuit, solder, or throw the battery into the fire. Also, do not expose it to liquid or strong shock.

Doing so will cause the battery to produce heat, explode, ignite, or leak, resulting in injury and fire.

● Shut off the external power supply (all phases) used in the system before cleaning the module or retightening the terminal block screws or connector screws. Failure to do so may result in electric shock.

[Startup and Maintenance Precautions]

CAUTION

● Before performing online operations (especially, program modification, forced output, and operating status change) for the running CPU module from the peripheral device connected, read relevant manuals carefully and ensure the safety. Improper operation may damage machines or cause accidents.

● Do not disassemble or modify the module. Doing so may cause failure, malfunction, injury, or a fire.

● Use any radio communication device such as a cellular phone or PHS (Personal Handy-phone

System) more than 25cm away in all directions from the programmable controller. Failure to do so may cause malfunction.

● Shut off the external power supply (all phases) used in the system before mounting or removing a module. Failure to do so may cause the module to fail or malfunction.

● Tighten the terminal block screws or connector screws within the specified torque range.

Undertightening can cause drop of the component or wire, short circuit, or malfunction. Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.

● After the first use of the product (module, display unit, and terminal block), do not connect/disconnect the product more than 50 times (in accordance with IEC 61131-2). Exceeding the limit may cause malfunction.

● Before handling the module, touch a conducting object such as a grounded metal to discharge the static electricity from the human body. Failure to do so may cause the module to fail or malfunction.

CHAPTER 3 BEFORE USING I/O MODULE

3.2

Output Module

(1) Common precautions for all output modules

(a) Maximum switching frequency when the module drives Inductive load.

The output must be on for one second or longer and off for one second or longer.

(b) Load for connection

When connecting a counter or timer that has a DC-DC converter as a load, select an output module whose maximum load current is larger than inrush current of the load.

Selecting an output module by average current of the load may cause a failure of the module because inrush current flows at a constant frequency at power-on or during operation due to the connected load.

If an output module needs to be selected by average current of the load, take either of the following actions to reduce an influence from inrush current.

• Connecting a resistor to the load in series

(b) Effects to relay life due to connected load

The actual relay life may be significantly shortened compared to the relay life curve, depending on the type of a load connected and the characteristics of inrush current. ( current may cause the module contact welding.

Page 23, Section 3.2 (3) (a)) Also, the inrush

Take the following measures to prevent shortening of the relay life and the contact welding.

• Select a load so that the inrush current will be within the rated current of the module.

• Connect an external relay that can withstand the inrush current.

The following table shows the relation between the road and the inrush current.

Select a load so that the inrush current (i) and the rated current (io) will be within the rated switching current specified for the output module used.

The inrush current may flow for a longer time depending on the load.

Typical electric-discharge lamp circuit includes discharge tubes, transformers, choke coils, and capacitors. Therefore, note that the inrush current may flow 20 to 40 times as large as the rated current in the case of high power factor and low power impedance.

When the wiring of the circuit is long, take care of the wire capacity.

24


(c) Measures against back EMF

Configure a contact protection circuit for extending the contact life, preventing noise when the contact is cut off, and suppressing the generation of carbide and nitric acid due to arc discharge.

An Incorrect contact protection circuit may cause contact welding.

Also, when using the contact protection circuit, the recovery time may be long.

The following table shows the representative examples of the contact protection circuit.

Example Method for selecting elements Remarks

*1

Capacitor + Resistor method (CR method)

Capacitor

Resistor

Capacitor

Resistor

Inductive load

Inductive load

Refer to the following for constants of the capacitor and resistor. Note that the following values may differ depending on a nature of the load and a variation of characteristics of it.

• Capacitor: 0.5 to 1(µF) against load current of 1A

• Resistor: 0.5 to 1(

) against power supply voltage of 1V

Use a capacitor whose withstand voltage is equal to or more than the rated voltage. In

AC circuit, use a capacitor having no polarity.

If a load is a relay or solenoid, the recovery time delays.

A capacitor suppresses electric discharge while a contact is off, and a resistor restricts a flow of current while a contact is on.

Diode method

Diode

Inductive load

Use a diode that meets both conditions shown below.


• The forward current is equal to or more than 2 times as large as the load current.

The recovery time is slower than the CR method.

Diode + Zener diode method

Diode

Zener Diode

Inductive load

Use zener voltage for the zener diode equal to or more than the power supply voltage.

This method is effective when the recovery time delays considerably by the diode method.

Varistor method

*1

Varistor

Inductive load

Select a cut voltage (Vc) for the varistor to meet the following condition.

• Vc > Power voltage × 1.5(V)

• Vc > Power supply voltage × 1.5(V) × √2

(when using AC power supply)

This method is not effective when the Vc is too high

The recovery time delays slightly.

When using AC power, impedance of CR must be larger enough than it of the load (prevention of a malfunction due to leak current from the CR).

3

● Avoid providing a contact protection circuits shown below.

These circuit are effective for preventing an arc at shut-off. However, the contact welding may occur because the charge current flows to capacitor when the contact turns on or off.

A DC inductive load is usually harder for switching than a resistor load, but if a proper protection circuit is configured, the performance will be similar to the resistor load.

Capacitor

Inductive load

Capacitor

Inductive load

● A protection circuit must be provided closely to a load or contact (module). If their distance is far, the protection circuit may not be effective. Appropriate distance is within 50 cm.

25

(4) Precautions for using the triac output module

(a) Measures against back EMF

Take measures against back EMF to the side where the load is connected if the wiring distance from the output module to the load is long.

If not, the surge suppressor in the output module may not work effectively.

• Capacitor: 0.5 to 1(µF) against load current of 1A

• Resistor: 0.5 to 1(

) against power supply voltage of 1V

Use a capacitor whose withstand voltage is equal to or more than the rated voltage.

Use a capacitor having no polarity.

Remarks

If a load is a relay or solenoid, the recovery time delays.

Varistor method

Output Module Specifications

The following output module equips the overload protection function and the overheat protection function.

Applicable model

 LY40NT5P, LY41NT1P, LY42NT1P, LY40PT5P, LY41PT1P, LY42PT1P

Function

Overload protection function

*1

Overheat protection function

*1

Description

• If the output module detects overcurrent, it limits output current by the current limiter operation

*2

• For the overcurrent detection value and the limited current, refer to "Overload protection function" on the module specifications.

• When the load current becomes lower than the overcurrent detection value, the module returns to normal operation.

• If overcurrent keeps flowing due to overload, heat is generated inside the module. When high heat is detected inside the module, the output is turned off.

• The number of output points that the overheat protection function simultaneously operates differs depending on the module. For the number, refer to "Overheat protection function" on the module specifications.

• After heat goes down, the module returns to normal operation.

*1

*2

This function is for protecting the internal circuit of the module, not for protecting external devices.

Also, leaving the failure too long may rise the internal temperature of the module, resulting in deterioration of output elements and/or discoloration of a case and printed circuit board. When the failure occurs, turn off the corresponding outputs immediately to remove the causes.

This operation limits overcurrent to a constant value and keeps outputting it.

I/O Combined Module Specifications

The I/O combined module equips the overload protection function and the overheat protection function.

Function


*1


*1

Description

• If the output side detects overcurrent, it limits output current by the current limiter operation

*2

• For the overcurrent detection value and the limited current, refer to "Overload protection function" on the module specifications.

• When the load current becomes lower than the overcurrent detection value, the module returns to normal operation.

• If overcurrent keeps flowing due to overload on the output side, heat is generated inside the module. When high heat is detected inside the module, the output is turned off.

• The number of output points that the overheat protection function simultaneously operates differs depending on the module. For the number, refer to "Overheat protection function" on the module specifications.

• After heat goes down, the module returns to normal operation.

*1

*2

This function is for protecting the internal circuit of the module, not for protecting external devices.

Also, leaving the failure too long may rise the internal temperature of the module, resulting in deterioration of output elements and/or discoloration of a case and printed circuit board. When the failure occurs, turn off the corresponding outputs immediately to remove the causes.

This operation limits overcurrent to a constant value and keeps outputting it.

Calculation example

Case

The resistance value of a connected resistor is calculated by the following formula.

Ex.

A switch with LED indicator that generates a current leakage of 2.82mA when 24VDC is supplied is connected to the LX40C6.

Check the following with the specifications of the module.

• Off current: 2.0mA

• Input resistance. 3.8k

Z

=2.82-2.0=0.82[mA]

To hold the current leakage through the LX40C6 equal to or lower than the off current (2.0mA), connect a resistor so that 0.82mA or more current flows to the resistor. Calculate the resistance value (R) of the connected resistor as follows.

The resistance value R < 9.27k must be met.

<Checking a connected resistor by calculating the power capacity.>

When the resistor (R) is 8.2k

W=

Since the resistor requires the power capacity of 3 to 5 times as large as the actual power consumption, the resistor connected to the terminal should be 8.2k

Off voltage when the resistance (R) is connected is calculated as follows.

(3) A signal incorrectly inputs data.

Case

Noise has been taken as input data.

Set the input response time longer. (


Ex.

1ms

 5ms

If this action is not effective, also take the following two measures.

• To prevent excessive noise, avoid installing power cables together with I/O cables.

• Connect surge absorbers to noise-generating devices such as relays and conductors using the same power supply or take other noise reduction measures.

If excessive noise is periodically generated, setting the response time shorter may be effective.

Ex.

70ms

 20ms

8.2

Troubleshooting for Output Circuit

Cause

(1) When the output is off, excessive voltage is applied to the load (triac output).

Case

• The load is half-wave rectified internally. (In some cases this is true of solenoids.)

TRIAC output module

D1

[1]

Load

[2]

• When the polarity of the power supply is as shown in [1], C is charged. When the polarity is as shown in [2], the voltage charged in C plus the line voltage are applied across D1. Maximum voltage is approx. 2.2E. (If a resistor is used in this way, it does not pose a problem to the output element. But it may cause the diode, which is built into the load, to deteriorate, resulting in a fire, etc.)

• Connect a resistor (several tens to hundreds of k

) across the load.

• In such a case, the load current flows into a phototriac as shown above because the triac does not operate. If an inductive load is connected with the load current flowing into a phototriac, the load may not turn off because the surge at the time of off is applied to the phototriac.

• Connect a resistor across the load so that the load current is equal to or higher than the minimum load current.

Cause

(3) A load momentarily turns on when powering on the external power supply.
