Adjusting zero point

Exiting zero point adjustment

Zero Point Adjustment

Adjust the pressure indication at the time of pressure release in the pressure port to "zero".

Piping

Piping and Installation

Hold the base section of the main body to connect a commercially available fitting（M5 male screw）to the main body. Tighten with a torque of １.０ N・m or less.

（Note）Do not apply any force on the cover section of the main body during tightening. The switch unit may break.

Back mounting screws

The main body can be secured to the panel by using the mounting screw holes located on the back（2−M3, effective depth: 6mm）. To install, hold the unit on

the base section when tightening the screws. Use a tightening torque of 0.3 N・m or less.

（Note）Do not apply any force on the cover section of the main body during tightening. The switch unit may break.

Angled Brackets（Option）

Port Block (sold separately)

If using the port block（sold separately）, put the O-ring（P8）in the O-ring groove located on the

back of the main body as shown in the figure below, and install the port block by two M3×10 male

screws. When installing, hold the base section of the main body, then tighten the male screws.

Use a tightening torque of 0.3 N・m or less.

When connect a fitting to the port block, wind sealing tape around the pipe to prevent air leakage.

The other pressure port which are not to be used should be stopped up with the sealing screw

provided. In this case, wind sealing tape around the screws before using. Any firstly tighten the screws using

fingers to avoid damage to the screw threads. Finally,tighten firmly with a wrench.(Recommended torque:3.0N・m)

For piping work, secure the port block using a 12mm wrench. Use a tightening torque of 10.0 N・m or less.

（Note）Do not apply any force to the cover section of the main body during tightening. The switch unit may break.

If using the angled bracket for wall attachment（sold separately）or the angle bracket for floor attachment（sold separately）,install the angled bracket by two M3×4

male screws as shown in the figure below.

If using the angled bracket and the port block, install both the angled bracket and the port block by two M3×10 male screws.

When installing, hold the base section of the main body, then tighten the male screws. Use a tightening torque of 0.3N・m or less.

（Note）Do not apply any force to the cover section of the main body during tightening.The switch unit may break.

Release the applied pressure in the pressure port

（i.e., let the pressure port be opened to the atmosphere）.

Press the    and   buttons simultaneously in Operations Mode.

The value     will blink when you enter the zero point adjustment phase.

Release the applied pressure on the pressure port

（opened to the atmosphere）,then perform zero point

adjustment again.
