SAFETY PRECAUTIONS
(Read these precautions before using.)
When using Mitsubishi equipment, thoroughly read this manual and the
associated manuals introduced in this manual. Also pay careful attention to
safety and handle the module properly.
These SAFETY PRECAUTIONS classify the safety precautions into two
categories: “DANGER” and “CAUTION”.
DANGER
CAUTION
Procedures which may lead to a dangerous condition and
cause death or serious injury, if not carried out properly.
Procedures which may lead to a dangerous condition and
cause superficial to medium injury, or physical damage
only, if not carried out properly.
Depending on circumstances, procedures indicated by CAUTION may also
be linked to serious results.
In any case, it is important to follow the directions for usage.
Store this manual in a safe place so that you can take it out and read it
whenever necessary. Always forward it to the end user.
[DESIGN PRECAUTIONS]
DANGER
Do not write data to the "read-only area" in the buffer memory of the
intelligent function module.
Do not turn on/off the "reserved" signals among the I/O signals to/from the
PLC CPU.
Doing so can malfunction the PLC system.
Depending on the malfunction of the external output transistor, there may
be cases where the output is ON or OFF status. Install external monitoring
circuitry for output signals that may lead to major accidents.
CAUTION
Do not bunch the control wires or communication cables with the main
circuit or power wires, or install them close to each other.
They should be installed 100 mm(3.94 inch) or more from each other.
Not doing so could result in noise that may cause malfunction.

A - 2
[INSTALLATION PRECAUTIONS]
CAUTION
Use the PLC in an environment that meets the general specifications
contained in the CPU user's manual.
Using this PLC in an environment outside the range of the general
specifications may cause electric shock, fire, malfunction, and damage to
or deterioration of the product.
When installing the module, securely insert the module fixing tabs into the
mounting holes of the base module while pressing the installation lever
located at the bottom of the module downward.
Improper installation may result in malfunction, breakdown or the module
coming loose and dropping. Securely fix the module with screws if it is
subject to vibration during use.
Tighten the screws within the range of specified torque.
If the screws are loose, it may cause the module to fallout, short circuits, or
malfunction.
If the screws are tightened too much, it may cause damage to the screw
and/or the module, resulting in fallout, short circuits or malfunction.
Switch all phases of the external power supply off when mounting or
removing the module.
Not ding so may cause electric shock or damage to the module.
Do not directly touch the conductive area or electronic components of the
module.
Doing so may cause malfunction or failure in the module.
[WIRING PRECAUTIONS]
CAUTION
Be careful not to let foreign matters such as sawdust or wire chips get
inside the module.
They may cause fires, failure or malfunction.
The top surface of the module is covered with protective film to prevent
foreign objects such as cable offcuts from entering the module when wiring.
Do not remove this film until the wiring is complete.
Before operating the system, be sure to remove the film to provide
adequate heat ventilation.
Be sure to fix communication cables or power supply cables leading from
the module by placing them in the duct or clamping them.
Cables not placed in the duct or without clamping may hang or shift,
allowing them to be accidentally pulled, which may cause a module
malfunction and cable damage.

A - 3
[WIRING PRECAUTIONS]
CAUTION
Do not grab on the cable when removing the communication or power
cable connected to the module.
When disconnecting a cable without a connector, first loosen the screws on
the part that is connected to the module.
Pulling the cable when it is still connected to the module may cause
damage to the module or cable, or misoperation due to cable contact
failure.
Always ground the shielded cable for the PLC.
There is a risk of electric shock or malfunction.
When wiring, be sure to verify the rated voltage of the product as well as
the terminal layout. Fire or failure may result if incorrect voltage is input or
incorrect wiring is performed.
Connecting terminals with incorrect voltage may result in malfunction or
mechanical failure.

5. WIRING
5.1 Wiring Instructions
(1) Use separate cables for the AC control circuit and Q64TCTT(BW)'s external
input signals to avoid the influence of AC side surges and inductions.
(2) Do not run the module cables near, or bundle them with, the main circuit
and high-voltage cables and the load cables from other than the PLC.
Always place the temperature sensors more than 100mm (3.94inch) away
from the main circuit cables and AC control circuit. Fully keep the sensors
away from high-voltage cables and circuits which include high frequencies,
e.g. inverter's main load circuit.
Not doing so can make the sensors more susceptible to noises, surges and
inductions.
(3) Earth the shielded wire or shielded cable to FG of the PLC.
However, depending on the external noise conditions, external earthing
may be recommended.

POINT
When using the heater wire break detection feature, you need to make CT
input channel assignment setting.
In the above wiring example, as CT1 is used with the loop of channel 1, set 1
(channel 1) to the channel assignment setting buffer memory (108H) of CT1.

6. SETTING FROM GPPW
The Q64TCTT(BW) allows you to set the output status at an error stop of the
PLC CPU by making the intelligent function module switch setting.
Make the intelligent function module switch setting using the I/O assignment
setting of GPPW.
You can make setting easily by entering hexadecimal numbers into 4 digits.
