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.

DPS Example:
Value “A” = 100 PSIG
Value “B” = 80 PSIG
P1 = 100 - 100 - 80
4
P1 = 95 PSIG
H = 100 - 80
2
H = 10 PSIG
Use or to select key lock / unlock mode.
To prevent unauthorized or accidental tampering with the switch settings
select the “Lock Mode” function. Panel will display “Key symbol” .
