BEFORE USE ....
Thank you for choosing us. Before use, please check con-
tents of the package you received as outlined below.
If you have any problems or questions with the product,
please contact our sales office or representatives.
■PACKAGE INCLUDES:
DC current input alarm module.........................................(1)
■MODEL NO.
Confirm Model No. marking on the product to be 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 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.
■UNUSED INPUT CHANNELS
• Set the unused input channels to ±20mA or 0 – 20mA
range. Unused channels left open with 4 – 20mA setting
are 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 ±20mA 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 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).

ALARM SETTING
The following parameters are programmable using the PC
Configurator Software (model: R3CON).
■ALARM TRIP POINT (-15.00 to +115.00%; factory set to
A1: 80.00, A2: 60.00, A3: 40.00, A4: 20.00)
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 100.00%; 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.
