■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 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: R5-BS).

(*) Factory setting
*1. When switching Monitor mode to another, set the rotary switch to a desired SW position and then press UP/DOWN button, so
that the mode is switched. Along with mode switching, RUN LED turns to blinking as shown in the table. Setting the rotary
switch to 0, the mode is automatically switched to Monitor mode in a few seconds.
*2. Red when the bus A operates normally;
Green when the bus B operates normally;
Amber when both buses operate normally.
• Zero/Span Adjustment Modes
Monitor Mode
Re-transmits the input signal as output in proportion.
Output 0% Adjustment Mode
Adjusts the 0% output signal using the front UP/DOWN
buttons, in monitoring the output value with a multimeter.
SW1 through SW3 switch the internal increments by 1, 5
and 10.
Output 100% Adjustment Mode
Adjusts the 100% output signal using the front UP/DOWN
buttons, in monitoring the output value with a multimeter.
SW4 through SW6 switch the internal increments by 1, 5
and 10.
Simulated Output Mode
Outputs the simulated signals of 0%, 50% and 100%.
• How to Operate
1) Start up in Monitor Mode (SW position = 0) and wait for
2 or 3 seconds.
2) Switch to another mode and go through the adjustments.
3) Reset the switch to the position ‘0’ so that the new setting
is stored in the internal memory.
PC CONFIGURATOR
With configurator software, settings shown below are available.
Refer to the software manual of R5CON for detailed operation.
