WARNING

Never use this product as a sensing device for personnel protection.

●

In case of using sensing devices for personnel protection, use products which meet laws and standards, such as

●

OSHA, ANSI or IEC etc., for personnel protection applicable in each region or country.
In case this sensor is used within Japan, SI unit must be used since use of pressure units in Japan is restricted to SI units.

SETTING OF PRESSURE LEAD
DIRECTION AND PIPING

Standard type

●

Setting of pressure lead direction

・

The pressure lead
direction can be changed
by dismantling the
pressure port attachment
and changing the
mounting direction. The
tightening torque of the
hexagon-socket-head
bolt (length 9mm or less)
should be 0.29N･m or
less.

Please make sure to close any unused pressure port with

●

Piping

・

When connecting a
hexagon-socket-head plug
or coupling to the pressure
port, hold the hexagonal
part of the pressure port
with a 12mm spanner and
make sure that the
tightening torque is 9.8N･m or less. Also, in order to
prevent any leakage, wind a sealing tape on the
coupling when connecting.
However, sealing tape is not required for North

Piping for pressure measurement inlet port

・

When connecting a coupling to the pressure measurement
inlet port, hold the pressure port attachment with a spanner
and make sure that the tightening torque is 9.8N･m or less.
Also, in order to prevent any leakage, wind a sealing
tape on the coupling when connecting.

●

Piping for atmospheric pressure inlet port

・

If there is a possibility of
water entering into the
sensor enclosure through
the atmospheric pressure
inlet port, connect a tube
to the atmospheric
pressure inlet port through
a M5 coupling and extend
the other end of the tube
to a safe place. In this
case, ensure that this end
of the tube does not get
clogged.

ANALOG BAR DISPLAY

Pressure changes are displayed in an analog fashion by using LED bars.

●

Hence, any sudden changes in pressure can be detected at a glance.
The analog bar display shows the measured pressure,

●

irrespective of the pressure unit, in steps of 10% F.S. approx.

Please refer to ' SETTING ② Initial setting' for the

the key changes the settable digit.
In the Set Value 1, 2 modes,

・

pressing the key changes the set
value to the high pressure side in
case of positive pressure type sensor
and to the high vacuum side in case

the key changes the set conditions.
In the Set Value 1, 2 modes,

・

pressing the key changes the set
value to the low pressure side in
case of positive pressure type sensor
and to the low vacuum side in case
of vacuum pressure type sensor.
In the sensing mode, if the key is

・

pressed continuously for 4 sec. or more,
the display shows bottom hold value.
Pressing the key changes the selected

set mode and Set Value 2 (P2) set mode.
In the sensing mode, if the key is

・

pressed continuously for about 3 sec.,
