Refer to the final page for the Warranty.
GENERAL
MISUSE OF THIS PRODUCT MAY CAUSE DAMAGE TO
EQUIPMENT OR PERSONAL INJURY. THESE INSTRUCTIONS
MUST BE THOROUGHLY READ AND UNDERSTOOD BEFORE
DEVICE IS INSTALLED.
PRIOR TO INSTALLATION, CHECK THE WETTED PARTS
MATERIAL FOR COMPATIBILITY TO THE PROCESS MEDIA.
54 Series pressure switches are activated when a
bellows, diaphragm or piston sensor responds to a
pressure change. This response, at a predetermined
set point, actuates one or two snap-acting switch(es),
converting the pressure signal into an electrical
signal. Control set point may be varied by turning the
adjustment hex on “J” types or a reference adjustment
dial on “H” types. (See Adjustment -PART II).
PROOF PRESSURE * LIMITS LISTED ON NAMEPLATE
MUST NEVER BE EXCEEDED, EVEN BY SURGES IN THE
SYSTEM. OCCASIONAL OPERATION OF UNIT UP TO PROOF
PRESSURE IS ACCEPTABLE, E.G., START-UP AND TESTING.
EXCESSIVE CYCLING AT MAXIMUM PRESSURE LIMIT COULD
REDUCE SENSOR LIFE. CONTINUOUS OPERATION SHOULD
NOT EXCEED THE DESIGNATED OVER RANGE **.
* Proof Pressure - the maximum pressure to which a pressure
sensor may be occasionally subjected, which causes no permanent
damage (e.g., start-up, testing). The unit may require re-gapping
(consult factory for re-gapping procedure).
** Over Range Pressure - the maximum pressure to which a pressure
sensor may be continuously subjected without causing damage and
maintaining set point repeatability.
THIS PRODUCT DOES NOT HAVE ANY FIELD REPLACEABLE
PARTS. ANY SUBSTITUTION OF COMPONENTS SHALL
INVALIDATE AGENCY CERTIFICATION(S).
DEVICE MUST NOT BE ALTERED OR MODIFIED AFTER
SHIPMENT. CONSULT UE IF MODIFICATION IS NECESSARY.
Please refer to product datasheet at www.ueonline.com
for product speci cations.
Part I - Installation
Mounting
• Adjustable Wrench
• Screwdriver
INSTALL DEVICE WHERE SHOCK, VIBRATION AND
TEMPERATURE FLUCTUATIONS ARE MINIMAL. DO NOT
INSTALL DEVICE IN AMBIENT TEMPERATURES THAT EXCEED
PUBLISHED LIMITS ON THE NAMEPLATE.
DEVICE SHOULD BE MOUNTED TO PREVENT MOISTURE
FROM ENTERING THE ENCLOSURE. VERTICAL MOUNTING IS
RECOMMENDED.
CONSIDER THE USE OF A PRESSURE SNUBBER IF SEVERE
PRESSURE SURGES ARE EXPECTED.
FOR PRESSURE MODELS, MOUNT VIA PRESSURE CONNECTION.
ALWAYS USE A WRENCH ON PRESSURE CONNECTION HEX (SEE
FIGURE 1). DO NOT TIGHTEN BY TURNING THE ENCLOSURE AS
THIS WILL DAMAGE THE SENSOR AND WEAKEN WELDED JOINTS.
Pipe Mounting: Mount the switch directly to the line via
the NPT pressure connection.
Vertical Surface Mount: Two holes for #10 screws are
provided in the bracket plate (see Figure 1 for J54, J54AS
& H54S. See Dimensions page for J54, J54A & H54).
Wiring
DISCONNECT ALL SUPPLY CIRCUITS BEFORE WIRING DEVICE.
WIRE DEVICE IN ACCORDANCE WITH LOCAL AND NATIONAL
ELECTRICAL CODES. MAXIMUM RECOMMENDED WIRE SIZE
IS 14 AWG AND RECOMMENDED TIGHTENING TORQUE FOR
FIELD WIRING TERMINALS IS 7 TO 17 IN-LBS.
DO NOT EXCEED ELECTRICAL RATINGS LISTED ON
NAMEPLATE. OVERLOAD ON A SWITCH CAN CAUSE
FAILURE EVEN ON THE FIRST CYCLE.

IMP54 082
Bring wires up to the terminals
from the rear, so that wires lay
along insulator. The three switch
terminals are clearly labeled
“common,” “normally open” and
“normally closed”.
For devices with protective covers:
❶ Remove cover by removing the one captive screw located on the
front of the cover.
❷ Conduit Connection: A 7/8” diameter hole has been provided in
the bracket plate for installing a conduit tting.
For optional switches supplied with leadwires, the
following color coding applies:
Manual Reset (Option 1530)
SPDT
Common Violet
Normally Open Blue
Normally Closed Black
Part II - Adjustments
• 1/4” open end wrench
• Flatblade screwdriver
Single Switch Devices
J54, J54S (no reference dial)
❶ Mount switch onto a calibrated pressure source (or vacuum
source for model 22 and 126).
❷ Secure tting to source tight enough to prevent leaks. Apply
tightening torque to the tting only.
❸ Use pipe sealant or Teon® tape to ensure tight seal.
❹ Using a 1/4” open end wrench, turn main adjustment screw
counterclockwise to lower set point or clockwise to raise set point.
(See Figure 2).
H54, H54S (with reference dial)
❶ Turn the reference dial to desired set point by aligning setting on
dial with dowel pin. (See Figure 3).
ON DUAL SWITCH UNITS, “LOW SET” SWITCH MUST
ALWAYS BE SET EQUAL OR BELOW THE “HIGH SET” SWITCH
(SEE FIGURE 4).
Dual Switch Devices
Follow steps 1-3 for J54 & J54S then continue with
adjustment for High and Low Set below.
High Set
❶ Using a 1/4” open end wrench, slowly turn the main adjustment
screw counterclockwise until the “High Set” switch transfers. If switch
does not transfer, turn the main adjustment screw clockwise until the
switch transfers, and then counterclockwise until it transfers again.
The “High Set” switch should now transfer on “pressure rise.”
❷ If it is desired that the switch transfer on “pressure fall,” turn the
main adjustment screw clockwise until the switch transfers again
(see Figure 4).
Low Set
❶ Using a 1/4” open end wrench, slowly turn the main adjustment
screw clockwise until the switch transfers. If switch does not
transfer, turn the low set adjustment screw counterclockwise until
the switch transfers, and then clockwise until it transfers again. The
“Low Set” switch is now set to actuate on “pressure fall.”
❷ If it is desired that the “Low Set” switch transfers on “pressure
rise,” turn the low set adjustment screw counterclockwise until the
switch transfers (see Figure 4).
Fine Adjustment
❶ If it is necessary to “ne adjust” the “High Set” setting, raise the
pressure source to a value slightly higher than the “High Set” pressure.
❷ Note the pressure at which the switch transfers (on rise).
❸ Lower the pressure source and note when switch transfers again
(on fall).
❹Turn the main adjustment screw clockwise to raise or counterclockwise
to lower the settings.
❺ If necessary, perform the same “ne adjustment” procedure outlined
prior for the “Low Set” switch.

Part III - Dimensions
All dimensions stated in inches (millimeters). Dimensional drawings for all models may be found at: www.ueonline.com
Manual Reset Button Option
Types J54 or H54 with option code 1530 incorporate a
snap switch which when actuated, remains actuated until
the pressure decreases and the reset button (located
on top of the control) is manually depressed to reset the
switch.
Adjustable Deadband Option
Control types with option code 1520 or models 16008
and 16009 incorporate a snap switch with internal
adjustment wheel. Turning this wheel raises or lowers
the pressure rise set point. The fall set point remains
constant.
To use the adjustable deadband switch:
❶ Determine set point and deadband values. For example, a rising
set point of 20 psi with a deadband value of 6 psi.
❷ Set the falling set point at desired deadband value (determined
by subtracting the deadband value from the desired set point)
using the standard adjustment screw as outlined above. Using the
example from step 1, 20 – 6 = 14, so you would set the fall set point
at 14 psi. This is your constant.
❸ Set your deadband by turning the adjustment wheel clockwise to
raise or counterclockwise to lower the set point. Using the example
from step 1, turn the wheel clockwise or counterclockwise until 20
psi is achieved. This is your set point.
Consult UE for additional information.
Recommended Practices
• A redundant device is necessary for applications
where damage to the primary device could endan-
ger life, limb or property. A high or low limit switch
is necessary for applications where a dangerous
runaway condition could result.
• Monitor operation to observe warning signs of pos-
sible damage to device, such as drift in set point.
Check device immediately.
• Preventative maintenance and periodic testing is
necessary for critical applications where damage
could endanger property or personnel.
