Do not use corrosive or flammable gases or liquid with this product.
Please use within the rated pressure range. Do not apply pressure beyond recommended maximum pressure,
permanent damage to the pressure sensor may occur.
Do not drop, hit or allow excessive shock. Even if switch body appears undamaged, internal components may
be broken and can cause malfunction.
Turn power off before connecting wiring. Incorrect wiring or short circuit will damage and / or cause malfunction.
Do not use in environment where steam or oil vapor is present.
This product is not explosion-proof rated. Do not use in atmospheres containing flammable or explosive gases.
Avoid wiring the sensor cable adjacent to or in the same cable tray with power or high voltage lines. Doing so
could cause malfunction due to noise.
This product is not a safety sensor. Its use is not intended to protect life and prevent bodily injury or property
damage from dangerous parts or machinery. It is a normal object detection sensor.

Sets number of milliseconds between the switch’s reading of the applied pressure
value and how quickly the output responds to that change. Prevents output chattering.
See Pressure Setting Modes
for more information
SoG = State “on” Green SoR = State “on” Red
Eg: If SoG is selected. When the Output State is “ON” the large display will be green. If the Output type selected below is “Normally Open”
(off) the large display is Red until set point is achieved. At that point the output closes (goes on) and the display will go Green. If the Output
type selected below is “Normally Closed” (on) the large display is Green until set point is achieved. At that point the output opens (goes off)
and the display will go Red.

Use when desired Pressure and Hysteresis values are known by operator.
The operator can teach the switch a maximum and minimum value used for P(n)1 and H calculations.
Pressure (DPS) or Vacuum (DVS) must be applied to the switch for it to learn the two values.
Use when desired Pressure and Hysteresis
values are not known.
Calculation of P1 Value
Value “A” = Maximum Value
Value “B” = Minimum Value
Value “H” Calculation Only
NOTES:
{ }
If Output Type “Normally Open” was selected the LCD - alternating display - will be (P_*) or if “Normally Closed” was selected the LCD - alternating display - will be (n_*) during this step.
When setting the P1 Hysteresis value or P1 / P2 Window comparator or H Hysteresis values momentarily depressing the up arrow will increase the pressure value by one digit,
maintaining the up arrow will rapid increase the value. Conversely, momentarily depressing the down arrow will decrease the pressure value by one digit, maintaining the down
arrow will rapid decrease the value.
Once the pressure setting step is complete momentarily depress to return to sensing mode or waiting 10 seconds will automatically default to sensing mode.
If Output Type “Normally Open” was selected the LCD display will be (AP 1) or if “Normally Closed” was selected the LCD display will be (An 1) during this step.
To exit Auto Setting mode with AP1 displayed, simultaneously pressing and momentarily will put the switch back to the sensing mode.
Once P1 and H values are established the switch will default back to Manual Setting mode allowing the operator to adjust P1 and / or H to suit application.
Select auto / manual setting mode during initial set-up.
To enter pressure setting mode, momentarily press button from sensing mode.
Indicates switch is in Auto Setting Mode
Prepare to cycle pressure (vacuum) to switch.
Cycle pressure (vacuum) to the switch multiple
times, the switch will memorize the max. value
“A” and min value “B” that were applied.
Afterwards, press SET once to store the setting
and return to the sensing mode.

Zero Calibration: Calibrate switch to zero under atmospheric conditions. Press the + buttons at the same
time until the “00” is shown. Release the buttons to end zero calibration.
Maximum Applied Pressure Display:
Press and hold button 2 seconds to enter the maximum value display mode. Panel will display “Max”. The sensor
will now detect and display the maximum pressure value applied, until reset. To reset, press and hold button for 2
seconds to return to the sensing mode.
Minimum Applied Pressure Display:
Press and hold button 2 seconds to enter the minimum value display mode. Panel will display “Min”. The sensor
will now detect and display the minimum pressure value applied, until reset. To reset, press and hold button for 2
seconds to return to the sensing mode.

It is recommended the Hysteresis value be set greater than the ±0.2% of FS repeatability. If set lower and the
applied pressure fluctuates too near the set point, it can cause the digital output to chatter.

DPS280 : When display unit is in “PSI”, setting resolution is 0.2 PSI.
DVS280 : When display unit is in “PSI”, setting resolution is 0.02 PSI.
In the pressure setting mode within the available set pressure range, using selected units the operator has preset the P(n)1 and/or {P(n)1
/ P(n)2} and a Hysteresis (H) value.
Hysteresis mode: (N.O. example) On ascending pressure the digital output will go on value at P1and go off when the pressure drops
below P1 by the H value selected.
Window comparator mode: (N.O. example) On ascending pressure the digital output will go on at P1 and go off at P2. On descending
pressure it will go on again when pressure drops below P2 by the H Value going off again when pressure drops below P1 by the H value.
From initial settings, digital output is selected either “Normally Open” or “Normally Closed”.

Once complete press to return to sensing mode.
This function allows operator to manually adjust
output display values on multiple switches with
identical applied pressure, therefore providing
uniformity of the display values.
Displayed values of the sensor can be calibrated or
adjusted to within a maximum of ±5% for DPS280
and ±2.5% for DVS280.
Use or button to adjust displayed value.
