(1) Mechanical vibration, shock and corrosive
gases least exist.
(2) Air is dry and temperature at room temperature
and stable.
NOTE: Although the manufacturer guarantees
stated performance at ambient temperatures
from -10 to +50℃ , it is recommended that the
instrument be placed in service in a room
temperature environment.
(3) Potential sources of inductive interference,
such as electromagnetic contactors, are locat-
ed su󱐰ciently away.
(4) A lightening arrestor is provided if incoming
signals are subject to potential influence of
lightening.
1. GENERAL
This distributor accepts a train of incoming pulses from the owmeter of most kinds, or other sig-
nal generating sources, shapes its wave form and, with desired pulse width, furnishes three sets
of mutually isolated outputs, isolated also from the input.
2. FEATURES
(1) Compactly built plug-in design. Easy to use and maintain.
(2) Provides a power supply to the pulse generator and preamplier (converter) of a variety of
owmeters.
(3) A free type power supply accepts 85-265VAC power source (or 20 to 30V DC in the DC version).
3. INSTALLATION
Installation Location
Select an installation location where
➡
(5) In an application where two or more distributors are to be installed side by side, a su󱐰cient
working space is secured behind the instrument to facilitate wiring and maintenance (see Fig. 3.1).
(6) For use in an environment where noise level is high, we recommend to use commercially
available noise lters, isolation transformers, or similar devices.

4. WIRING
(1) Separate eld wiring from other power lines
or power circuits to minimize the possibility
of inductive interference.
(2) Terminal arrangement is shown in Fig. 4.1.
(3) M3.5 ×7 screws are used for terminals.
Ensure good electrical connections.
(4) Upon completion of wiring connections,
install the distributor body into the socket.
Then engage the locking levers on the
socket assembly with the distributor body.
(5) For incoming signal cables from the owme-
ter or other signal sources, cables recom-
mended for the instrument of interest must
be used. Transmission length also depends
on the specication of that instrument.
For other signal cables, electrostati-
cal l y - shielded, polyethylene-insulated,
vinyl-sheathed control cables (CEVS 1.25
to 2.00mm2, 2- or 3-conductor), or equiv-
alent, must be used. With a conductor area
2 mm2, the maximum transmission length is
one kilometer.
CAUTION
Make electrical connections upon conrmation of validity of owmeter (pulse gen-
erator) and receiving instrument combination by their model No., serial No., etc.

Symptom Check Possible Causes
Power indicator lamp
(LED) fails to come on.
1. Inspect the power supply board.
Is power source type (AC/DC) in
conformity with the power supply
board?
2. Make sure of power source voltage. Is
an 85 to 246VDC (50/60Hz) power or
20 to 30V dc power Impressed across
terminals 11 (+) and 1 ( − )?
1. Power supply board is improper.
2. Line voltage is improper.
3. A fault In the internal power
board.
No pulse output. 1. Input signal line correctly wired?
2. Input signal coming in?
3. Pulse generator valid on the pulse
generator select board ?
1. Input wiring is incorrect.
2. Pulse generator is at fault.
3. Pulse generator select board is
incorrect.
4. Power supply board or pulse
generator select board or
distributor board in the internal
assembly is at fault.
6. PREPARATION AND OPERATION
(1) Ensure that the pulse distributor and related equipment are correctly installed and wired with
no place left unnished.
(2) Supply power to this instrument and make sure to see that the power indicator (red LED)
comes on.
(3) Initiate operation by allowing the uid to run.
Make sure to see that the power terminals are connected to a power source of the
rated voltage. Applying a power of incorrect voltage could ruin your instrument.
7. QUICK TROUBLESHOOTING
● If the trouble is suspected to be internal to the distributor, seek our service.
