High Pressure Low Set Point Pressure Switch
OVERVIEW
The Whitman Controls J205G High Pressure Low Set Point Pressure
Switches are among our most versatile offering, affording the end user
an extensive operating environment and a wide range of set point
optionality. These switches can be exposed to high pressure without
compromising integrity or switch functionality. Uses include gas bottle
change switches and oil or water supply control. They are frequently
used in pump and reservoir applications. The internals are stainless
steel with a diaphragm o-ring that is available in numerous compounds.

For dry circuitry, i.e. 5VDC·50 rnA or less, use gold contact switch (Code .1 or 1). If less than 20mA, performance of electrical swtich will be environmentally
dependent. II there is some form of contamination (dust, dirt, oil, chemical residue, etc.) at point of contact, the electrical switch could perform intermittently,
as there would be Insufficient current to burn off any possible contamination.

Set Point Adjustments/Wiring
Set Point Adjustments and Wiring Instructions
SET POINT ADJUSTMENTS
PRESSURE SET POINT ADJUSTMENT MODEL P88 K OR C SET
The standard field adjustable versions of the Guardian P/V Model
P88 are easily adjusted throughout the prescribed pressure range by
aligning the top of the knurled adjusting nut with the desired pressure setting indicated on the adjacent range scale.
PRESSURE SWITCHES
PRESSURE SET POINT ADJUSTMENT-JAM NUT STYLE ADJUSTING
RING MODELS P100, P117, W117, P119, J205, J705 -K OR C SET.
The K & C designs are readily adjustable throughout their prescribed
range by loosening the knurled locking ring. Turning the electrical
switch clockwise will lower the set point, turning it counterclockwise
will increase the set point. When desired set point is reached, the assembly is locked again by tightening the knurled locking ring.
PRESSURE SET POINT FOR ADJUSTABLE SWITCHES
All switches are easy to adjust. First, loosen the knurled locking ring.
Now, set the sliding gauge pointer to the desired pressure point.
Tighten the locking ring and the pressure (vacuum) switch
is locked and ready to use.
Entire adjustable range may be covered by rotating approximately
250o each side of the mean.
The knurled locking ring requires very little effort to establish a reliable locked position. By placing a wrench on the fitting hex to hold
switch body in position, grip the knurled locking ring with pliers and
turn counterclockwise to loosen or clockwise to tighten. Only a slight
snug is required to lock in position.
NOTE: Little effort is required to establish a reliable locked position.
If tools are used, place a wrench on the hex nut under the switch to
hold the switch body in place; then grip the knurled locking ring with
pliers to tighten or loosen as desired.
VACUUM SET POINT ADJUSTMENT – VACUUM MODELS
To lower set point turn electrical switch counterclockwise. To raise
set point turn electrical switch clockwise.
Loosen knurled ring, set
pointer to desired pressure and tighten ring
to hold in position.
PRESSURE SET POINT ADJUSTMENT – MODEL P605
Slide spring clip cover down past adjusting ring window. Insert .093
inch dia. pin into adjusting ring radial hole. Pushing the pin to the
right (counterclockwise) will lower the set point: to the left (clockwise) will raise the set point. Align center of pin holes to the desired
pressure. When desired set point is reached, remove pin and slide up
the cover to close the adjusting ring window.
On P605 Models, insert
the pin (provided) into
the adjusting ring
and align center of pin
holes to the desired pressure.
