Handling instructions and Precautions

●
Adjusting the range of the set pressure
1. Use the procedure below to adjust the range of the set pres-
sure (the green portion).
1. Adjust the lower limit of the range of the set pressure by
rotating the protrusions (2 places) clockwise with your hand.
2. Adjust the upper limit of the range of the set pressure by
rotating the protrusions (2 places) clockwise with your hand.

Surging, vibration, and shock
The
□
1.181 in. integrated pressure gauge is a precision device. It
cannot be used if the medium surges, or external vibration or
shock is applied.

Mounting (installation)
1. Read the "Handling Instructions and Precautions" for the filter
regulator and regulator when installing the
□
1.181 in. inte-
grated pressure gauge to the filter regulator or the regulator.
2. Install the
□
1.181 in. integrated pressure gauge to the filter reg-
ulator or regulator in the orientation shown in the diagram below.
Mounting (installation) and piping
NOTE
It is possible to change the

1.181 in. integrated pressure
gauge installation to a 180° orientation, but it is not possible
to change it to a 90° orientation.
NOTE
Adjusting the range of the set pressure with a tool may
damage component parts.
NOTE
Surges in the media, external vibrations or shocks may result
in damage to component parts.

Detection pressure scale
1. Use a detection pressure scale as a guideline.
●
Settings for the detection pressure
1. The detection pressure can be set to a value over the range of
detection pressure, but always set it within the specified val-
ues.
2. Detection pressure scale is for the set value when the sup-
plied pressure falls.
3. Detection pressure scale is for the set value when the OFF
signal is detected.
2. Use the following procedure to set the detection pressure.
①
Turn the adjusting screw toward the "
＋
" until the regulating
indicator is aligned with the desired detection pressure on
the scale.
②
Supply pressure and use a multi meter to confirm that the
signal indicates the desired pressure setting is detected.
Operation and maintenance inspections
NOTE
Use a multi meter to confirm the output of the pressure
switch module.
NOTE
Setting the pressure over the range of the detection pressure
will damage component parts.
NOTE
The ON signal is detected when the pressure exceeds the
set pressure on the detection pressure scale by the response
differential.
NOTE
To accurately set the detected pressure, use a separate
pressure gauge.
