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 Owners Manual.

Ask an authorized dealer or qualified installation professional to install or reinstall the relayinterface.

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 fromaffecting them.

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

CAUTION

Applications/Functions/Specifications

Applications

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

Power cables/Earth wires/Signal wires

Connection of Power cables/Earth wires/2 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 earthwire to the earthterminal on thechassis.

If an inductive load (relay coil) or a bulb is connected, a surge voltage or rush current will begenerated. 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 earthingThe shield earth of the RS-485 signal wires should be single-point earth. Earth the wires on the TouchScreen Controller.

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

Connection diagram

The shield earth of the RS-485signal wires should be single-pointearth. Earth the wires on the TouchScreen Controller.

Set the Digital Input/Output RelayInterface address with SW1. Assign1 to 4 to each address to avoidduplication. You can set the digitalInput/Output Relay Interface addressindependently from the TCC-LINKRelay Interface address or theEnergy Monitoring Relay Interface

address.CAUTION: The SW1 setting is readwhen the power is turned on. Pushthe reset switch (SW7) afterchanging the address.

TCS-NET RELAYINTERFACE

CAUTION: Set the RS-485terminator resistor on the TCS-NETRelay Interface. No terminator

resistor setting switch is providedon the Digital Input/Output RelayInterface.

The RS-485 signal wire haspolarity A and B. Be careful whenconnecting the wire.

4 Trial Operation CheckBefore 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.
