■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
• This equipment is suitable for Pollution Degree 2 and
Measurement Category II (output, transient voltage
2500V). Basic insulation (output to internal bus or in-
ternal power: 250V) is maintained. Prior to installation,
check that the insulation class of this unit satisfies the
system requirements.
• Altitude up to 2000 meters.
• The equipment must be mounted inside the instrument
panel of a metal enclosure.
• The equipment must be installed such that appropriate
clearance and creepage distances are maintained to con-
form to CE requirements. Failure to observe these re-
quirements may invalidate the CE conformance.
• 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).

FUNCTIONS
■OUTPUT HOLD or OUTPUT OFF
In normal conditions, the module outputs the signal from
the preferred bus A.
When an error is detected, the output is switched to the
data from the bus B.
• Output Hold
If both are in error, the module holds the signal and
stands by until one of the communications recovers.
• Output OFF
If both are in error, the module outputs OFF signals and
stands by until one of the communications recovers.
At the startup, it outputs OFF until the communication is
established and normal data is received.
