■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).

FUNCTIONS
■MANUAL COUNT RESET
1) Remove Network Module or its cables and interrupt com-
munication with other devices.
2) Turn ON the Count Reset SW.
3) Return the module to the base and turn the power supply
on.
4) ERR LED turns on and the module starts resetting its
counter. When the resetting is complete, the LED turns
to green. DO NOT remove the power while the red LED
is on. The RUN LED starts blinking at the same time.
5) After the green LED is confirmed, turn the power supply
off.
6) Turn OFF the Count Reset SW.
7) Return the Network module onto the base and turn the
power supply on.
Note: Count Reset SW must be turned OFF after this proce-
dure because the module does not start counting with
ON state.
■REMOTE COUNT RESET INPUT
With the Count Reset Input SW (SW3-3) turned ON, the
Pi 16 pulse input can be used to remotely reset the count
values.
SW3-3 = OFF: Pi 16 is used as a pulse input.
SW3-3 = ON: Pi 16 is used to reset the count values for the
Pi 1 through Pi 15. One pulse supplied at the Pi 16 will be
recognized as a reset signal.
■REMOTE COUNT RESET OPERATION
1) ERR LED turns on (red color) when the reset signal is
received.
2) In 1 second, the module starts resetting its counter.
When the resetting is complete, the LED turns to green.
3) After 1 second, ERR LED turns back to the state before
the reset signal has been received.
Note: Reset signals received while the module is processing (1)
through (3) are ignored.
■COUNT RESET FROM HOST PC/PLC
Refer to “COUNTER SETTING FROM HOST PC/PLC” sec-
tion hereafter.

Setting SW3-4 OFF and turning power on enable the function.
The bits indicating the channels to reset counter are allocated in the first word from host PC/PLC.
When these bits are changed from 0 to 1, the counter is reset. When it is confirmed that the counter is reset, return to 0.
Notice that if the bit remains at 1, the next reset will not work.
