Remarks: In the practice, even the temporal peak value of pressure, should no exceed the Max. Allowable
Pressure.
Special requirements on Dead Band or Connection can be designed customized

The Adjustment for Set Point
[Example] Choose Switch with Pressure Range from 2.4Mpa to 24Mpa, a contact signal is required to be
generated when pressure falls to 15Mpa(The Decreasing Set Point), see steps as following:

To screw the switch into connection of Oil Pressure Checkout Test Set. Exert pressure on it for 2 minutes
simulate its practical working situation, thereafter to make the setting.

Link the Out-put lead with Multimeter.
Screw-off the screws on the housing.
Add the pressure to 15Mpa, this value can be read from the standarded pressure gauge.
Use socket screwwrench (Φ 3mm), clockwise rotate the Set-point Adjusting Bolt, to make the Set-Point become
bigger, until it switches at 15Mpa.

Vering the testing pressure to make it change up and down arround 15Mpa, check if the Switch switches at
15Mpa when pressure falls, this value is the Decreasing Set Point need to be set, the correspondent Increasing
Set Point is within 16.9Mpa to 18Mpa.

Tighten the Locknut.

While removing the cover, please do not touch the components inside the switches.
The Set Point must be within the aAdjustable Range, Dead Band is expressed as Typical at MID-range.
Normally it is the 20% to80% of the Ajustable Range.

If the switches are outdoor application, sufficient protections are necessary, for the severe variation of the
ambient temperature, radiation of the sunlight, permeation of the corrosive gas or water, will influence the life of
the switches.

During the process of installation or disassembly, a spanner MUST be used to clip and tighten the sensor,
absolutely avoid the countermovent between the sensor and housing of the switches(please refer to the
drawings)
