■INSTRUCTION MANUAL

This manual describes necessary points of caution when

you use this product, including installation, connection and

basic maintenance procedures.

POINTS OF CAUTION

■CONFORMITY WITH EU DIRECTIVES

• The equipment must be mounted inside the instrument

panel of a metal enclosure.

• The actual installation environments such as panel con-

ﬁgurations, connected devices, connected wires, may af-

fect the protection level of this unit when it is integrated

in a panel system. The user may have to review the CE

requirements in regard to the whole system and employ

additional protective measures to ensure the CE conform-

ity.

■HOT SWAPPABLE MODULES

• Replacing the module does not affect other modules on

the same base. Thus, the module can be replaced while

the power is ON. However, replacing multiple modules

at once may greatly change live voltage levels. We highly

recommend to replace them one by one.

■GENERAL PRECAUTIONS

• DO NOT set the switches on the module while the power

is supplied. The switches are used only for maintenance

without the power.

■ENVIRONMENT

• Indoor use.

• When heavy dust or metal particles are present in the

air, install the unit inside proper housing with sufﬁcient

ventilation.

• Do not install the unit where it is subjected to continuous

vibration. Do not subject the unit to physical impact.

• Environmental temperature must be within -10 to +55°C

(14 to 131°F) with relative humidity within 30 to 90% RH

in order to ensure adequate life span and operation.

■WIRING

• Do not install cables close to noise sources (relay drive

cable, high frequency line, etc.).

• Do not bind these cables together with those in which

noises are present. Do not install them in the same duct.

■AND ....

• The unit is designed to function as soon as power is sup-

plied, however, a warm up for 10 minutes is required for

satisfying complete performance described in the data

sheet.

INSTALLATION

Use the Installation Base (model: R3-BSx).

• Unused Input Channels

Close across the unused input terminals with a resistor as

shown below and set the DIP switch for Pt 100 input.

Unused channels left open are equal to the burnout,

which turns the red ERR LED on and sets a burnout flag at

the PLC or the host device.

Connecting the resistor means approx. 0°C. An alarm

setpoint must be set to a value that does not trip an

unwanted alarm.

Unused channels can be specified and set so on the PC

Configurator Software (model: R3CON) without needing to

connect resistors at the field terminals.

ALARM SETTING

The following parameters are programmable using the PC

Conﬁgurator Software (model: R3CON).

■ALARM TRIP POINT

(-200.0 to +850.0°C or -328 to +1562°F; factory set to A1:

400.0°C, A2: 300.0°C, A3: 200.0°C, A4: 100.0°C)

Four alarm setpoints are selectable per each input.

■ALARM TYPE (High or Low; factory set to A1: High, A2:

High, A3: Low, A4: Low)

High or Low alarm is selectable for each alarm trip point.

High alarm: An alarm is set when the input signal goes

above the setpoint.

Low alarm: An alarm is set when the input signal goes be-

low the setpoint.

■DEADBAND (HYSTERESIS)

(0.00 to 100.0°C or 0 to 1800°F; factory set to 10.0°C or 100°F)

Deadband (deviation between the points where the alarm is

set and reset) is selectable for each alarm trip point.

■POWER ON DELAY TIME

(0.0 to 99.0 seconds; factory set to 5.0)

The alarm output start functioning in the preset time after

the power has been turned on.

This setting is common to all four points.

■ALARM ON DELAY TIME

(0.0 to 99.0 seconds; factory set to 1.0)

The alarm output is set when the preset time elapses after

the input has entered in the alarm range.

This setting is common to all four points.

■ALARM HOLD TIME

(0.0 to 99.0 seconds; factory set to 1.0)

The alarm output is held for the preset time even if it is

reset in shorter time.

This setting is common to all four points.

OUTPUT DATA DESCRIPTIONS

Four alarm setpoints are selectable per each input. One

(1) word (16 bit) data is transmitted to the PLC or the host

device via the R3 network module.
