Precautions for Safety

• Read these “Precautions for Safety” carefully before installation.

• The precautions described below include important items regarding safety. Observe them without fail.

• After the installation work, perform a trial operation to check for any problem. Follow the Owner's

Manual to explain how to use and maintain the unit to the customer. Ask the customer to keep this

Installation Manual together with the Owner’s Manual.

• Ask an authorized dealer or qualified installation professional to install or reinstall the relay

interface.

Improper installation may result in electric shock or fire.

• Turn off the main power supply switch or breaker before attempting any electrical work.

Make sure all power switches are off. Failure to do so may cause electric shock.

• Perform installation work properly according to this Installation Manual.

Improper installation may result in electric shock or fire.

• Do not modify the unit.

Any modification may cause a malfunction, resulting in overheating or fire.

WARNING

• Perform wiring correctly in accordance with specified the current capacity.

Failure to do so may result in short-circuiting, overheating, or fire.

• Connect the specified cables for the terminals securely to prevent external forces from

affecting them.

Failure to do so may result in disconnection, overheating, or fire.

Applications/Functions/Specifications

• Applications

The Digital Input/Output Relay Interface is used to control air conditioners by interlocking them with

electric lock signals and fire alarm signals, and to transmit air conditioner failures to other devices.

• Functions

The Digital Input/Output Relay Interface connects non-voltage contact signals, transmits their input

status to the Touch Screen Controller, and outputs signals from the contacts (open collector) according

to the command from the Touch Screen Controller.

using the attached pin terminal.

Power cables/Earth wires/Signal wires

Connection of Power cables/Earth wires/

Signal wires

Connect power cables, earth wires, and signal wires to the specified terminals on the terminal block.

The RS-485 signal wire has polarity. Connect A to A, and B to B. If connected with incorrect polarity,

the unit will not work.

CAUTION

Connect the earth

wire to the earth

terminal on the

chassis.

If an inductive load (relay coil) or a bulb is connected, a surge voltage or rush current will be

generated. Take adequate measures against surge voltage or rush current.

CAUTION

Wiring Connection

The following describes wiring connections of the Digital Input/Output Relay Interface when it is used in

the air conditioner control system.

•Terminator resistor setting

Set the RS-485 terminator resistor by the TCS-NET Relay Interface.

Do not set it by the Digital Input/Output Relay Interface.

• Shield earthing

The shield earth of the RS-485 signal wires should be single-point earth. Earth the wires on the Touch

Screen Controller.

Other shield lines should be closed, and the terminal end should be open and insulated.

• Connection of external digital inputs

Input circuit examples are shown below (electrically isolated using a photo-coupler).

earth. Earth the wires on the Touch

Screen Controller.

Set the Digital Input/Output Relay

Interface address with SW1. Assign

1 to 4 to each address to avoid

duplication. You can set the digital

Input/Output Relay Interface address

independently from the TCC-LINK

Relay Interface address or the

Energy Monitoring Relay Interface

address.

CAUTION: The SW1 setting is read

when the power is turned on. Push

the reset switch (SW7) after

changing the address.

TCS-NET RELAY

INTERFACE

CAUTION: Set the RS-485

terminator resistor on the TCS-NET

Relay Interface. No terminator

resistor setting switch is provided

on the Digital Input/Output Relay

Interface.

The RS-485 signal wire has

polarity A and B. Be careful when

connecting the wire.

• Set relay interface addresses according to the air conditioner address table.

• When the SW1 setting has been changed, push the reset switch SW7. The new address

setting is read.

CAUTION

The following settings are necessary to use Digital Input/Output Relay Interfaces.

• SW1 Address set switch

When two or more Digital Input/Output Relay Interfaces are used, set a different address for each

unit to avoid address duplication.

Assign addresses in ascending order.

• SW2 Operation mode set switch

• SW3 Test switch

• SW4 Test switch

• SW7 Reset switch

When performing address setting with SW1, push this reset switch after address setting to read

the set value.

These switches are not used during normal

operation. Set zero (0) or “all OFF”.

Trial Operation Check

Before starting trial operation

Turn on the power of the Digital Input/Output Relay Interface after all cable connections and settings are

completed. Turn on power of the air conditioning control system.

Trial operation

• Confirming external input connection

In the test mode, when the external inputs connected to the input terminals DI-1 to DI-8 are ON, the

respective LEDs will goes on so you can confirm the connection.

Confirming procedure:

Set the operation mode switch SW2 to “3”, and push the reset switch SW7 to enter the test mode.

Unless SW4 is pushed, the respective input status of DI-1 to DI-4 is indicated by LED2 to LED5.

When SW4 is pushed, the respective input status of DI-5 to DI-8 is indicated by LED2 to LED5.

(*) To return to the normal operation, reset SW2 to “zero (0)” and push SW7.

• Checking external output connection

In the test mode, you can set output terminals DO1 to DO4 to ON or OFF with the test switch. Their

output status is indicated by each LED.

Checking procedure:

Set the operation mode switch SW2 to “3” in the same way as the external input check, and then

push the reset switch SW7 to enter the test mode.

When the bit of the test switch SW3 is set to ON, the external output turns ON; when set to OFF,

the external output turns OFF.

Bits 1 to 4 of SW3 correspond to output terminals DO1 to DO4.

The respective output status of output terminals DO1 to DO4 is indicated by LED14 to LED17.

The LEDs light with the output ON, and goes off with the output OFF.

(*)To return to normal operation, reset SW2 to “zero (0)” and push SW7.
