MITSUBISHI

Thank you for buying the Mitsubishi general-purpose
programmable controller MELSEC-A Series.

Prior to use, please read both this manual and detailed
manual thoroughly and familiarize yourself with the product.

©1996 MITSUBISHI ELECTRIC CORPORATION

Before using this product, please read this manual and the relevant manuals carefully
and pay full attention to safety to handle the product correctly.
These precautions apply only to Mitsubishi equipment. Refer to the CPU module user’s
manual for a description of the programmable controller system safety precautions.
In this manual, the safety precautions are classified into two levels: "DANGER" and
"CAUTION".

Under some circumstances, failure to observe the precautions given under "
CAUTION" may lead to serious consequences.
Observe the precautions of both levels because they are important for personal and
system safety.
Make sure that the end users read this manual and then keep the manual in a safe place
for future reference.

(Read these precautions before using this product.)

DANGER

CAUTION

[Design Precautions]

• In the case of a communication failure in the network, data in the master
module are held.
Check the communication status information (SB, SW) and configure an
interlock circuit in the sequence program to ensure that the entire system
will operate safely.

• Do not install the control lines or communication cables together with the
main circuit lines or power cables.
Keep a distance of 100mm (3.94 inches) or more between them.
Failure to do so may result in malfunction due to noise.

[Installation Precautions]

CAUTION

• Use the programmable controller in an environment that meets the
general specifications in this manual.
Failure to do so may result in electric shock, fire, malfunction, or damage
to or deterioration of the product.

• For protection of the switches, do not remove the cushioning material
before installation.

• Do not directly touch any conductive part of the module.
Doing so can cause malfunction or failure of the module.

• Securely fix the module with a DIN rail or mounting screws. Tighten the
screws within the specified torque range.
Undertightening can cause drop of the screw, short circuit or malfunction.
Overtightening can damage the screw and/or module, resulting in drop,
short circuit, or malfunction.

[Wiring Precautions]

CAUTION

• Shut off the external power supply for the system in all phases before
wiring. Failure to do so may result in damage to the product.

• Ground the FG terminals to the protective ground conductor dedicated to
the programmable controller.
Failure to do so may result in malfunction.

• 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.

• Use applicable solderless terminals and tighten them within the specified
torque range.
If any spade solderless terminal is used, it may be disconnected when the
terminal screw comes loose, resulting in failure.

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

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

• Do not install the control lines or communication cables together with the
main circuit lines or power cables. Failure to do so may result in
malfunction due to noise.

• Place the cables in a duct or clamp them.
If not, dangling cable may swing or inadvertently be pulled, resulting in
damage to the module or cables or malfunction due to poor contact.

• When disconnecting the cable from the module, do not pull the cable by
the cable part. Loosen the screws of connector before disconnecting the
cable. Failure to do so may result in damage to the module or cable or
malfunction due to poor contact.

[Startup and Maintenance Precautions]

CAUTION

• Do not touch the terminals before shutting off the external power supply for
the system in all phases.
Doing so may cause malfunction.

• Do not change the setting jumper before shutting off the external power
supply for the system in all phases.
Doing so may cause failure or malfunction.

• Shut off the external power supply for the system in all phases before
cleaning the module or retightening the terminal screws.
Failure to do so may cause the module to fail or malfunction.

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

• Do not drop or apply strong shock to the module.
Doing so may damage the module.

• Shut off the external power supply for the system in all phases before
mounting or removing the module to or from the panel.
Failure to do so may cause the module to fail or malfunction.

• After the first use of the product, do not mount/remove the terminal block
to/from the module more than 50 times (IEC 61131-2 compliant).

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

4. Loading and Installation

The following is explanations of the handling precautions and installation
environment which is common to modules when handling AJ65BT-64AD from
unpacking to installation.
For the details of loading and installation of the module, refer to User's Manual of
programmable controller CPU module to be used.

4.1 Handing Precautions

The precaution when handling the AJ65BT-64AD are described below:
(1) Because the case of the module is mad of resin, be careful not to drop it or

expose it to strong impact.

(2) Perform the tightening of the module mounting screws in the folowing range.

Module mounting screw (M4 screw) 78 to 118 N⋅cm
Terminal block terminal screw (M3.5 screw) 59 to 88 N⋅cm
Terminal block mounting screw (M4 screw) 78 to 118 N⋅cm

Screw posit ion Tightening torque range

4.2 Installation Environment

Do not install the A series programmable controller in the following environments.
(1) W here the ambient temperature exceeds the 0 to 55°C range.
(2) W here the ambient humidity exceeds the 10 to 90 % RH range.
(3) W here condensation is produced by sudden temperature changes.
(4) W here corrosive or combustible gas is present.
(5) Where dust, iron powder and other conductive powder, oil mist, salt, or

organic solvents are prevalent.
(6) In direct sunlight.
(7) Where a strong electric or magnetic field is generated.
(8) Where vibration and shock may be applied directly to the module.

5. Data Link Cable Wiring

6. Wiring

The precautions and module connection example for wiring are described.

6.1 Wiring Precautions

To obtain maximum performance from the functions of AJ65BT-64AD and
improve the system reliability, an external wiring with high durability against noise
is required.
The precautions when performing external wiring are as follows:
(1) Use separate cables for the AC and AJ65BT-64AD external input signals, in

order not to be affected by the AC side surge or conductivity.

(2) Do not bundle or place with load carrying wires other than the main circuit

line, hight voltage line, or programmable controller. Noises, surges, or
conductivity may affect the system.

(3) Place a one-point grounding on the programmable controller side for the

shielded line or shielded cable. However, depending on the external noise
conditions, it may be better have a grounding externally.

6.2 Module Connection Example

The connection examples for voltage input and current input are shown below:
(1) For voltage input

Signal source 0 to ±10V

(2) For current input

Signal source 0 to ±20mA

*1 Use a two-core twisted shield line for the power cable.
*2 Indicates the AJ65BT-64AD input resistor.
*3 For the current input, be sure to connect the (V+) and (I+) terminals.
*4 When noise or ripple occurs with the external cable, connect a condenser

with about 0.1 to 0.47μF25WV between the terminal V and COM.

*5 Always perform grounding for FG1. When there is a lot of noise, it may be

better to ground AG as well.
If the grounding wiring (grounding yes/no) is changed after the offset and
gain are set, perform the setting of the offset/gain values again.
