INSTRUCTION MANUAL

BEFORE USE ....

Thank you for choosing M-System. Before use, please check
the contents of the package you received as outlined below.
If you have any problems or questions with the product,
please contact M-System’s Sales Office or representatives.

■ PACKAGE INCLUDES:

DC voltage input alarm module ....................................(1)

■ MODEL NO.

Check that model No. described on the specification label is
exactly what you ordered.

■ 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 con­figurations, connected devices and connected wires may
affect 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 CE conformity.

■ HOT INSERTION/REMOVAL OF MODULES

•Removing or replacing modules does not affect other mod­ules on the same backplane. It is possible to replace them
without removing the power supply. However, replacing
multiple modules at once may greatly change line voltage
levels. We recommend that you replace them one by one.

■ 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.

■ UNUSED INPUT CHANNELS

•Set the unused input channels to ±10V range. Unused
channels left open with other settings may be equal to the
input lower than -15%, which sets a data abnormality at
the PLC or the host device.

Open circuit with the input range set to ±10V means 50%

of the full-scale. 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
the above mentioned setting.

■ AND ....

•The unit is designed to function as soon as power is sup­plied, 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).

ALARM SETTING

The following parameters are programmable using the PC
Configurator Software (model: R3CON).

■ ALARM TRIP POINT (-15.00 to +115.00%)

Four alarm setpoints are selectable per each input.

■ ALARM TYPE (High or 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 100.00%; factory set to 5.00)

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.
