Please read all instructional literature carefully and thoroughly before starting.
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.
Type B54, B54S, C54, C54S, C54A, C54AS (Immersion Stem)
Temperature variations are sensed by a liquid  lled sensor
which expands or contracts against a bellows which
actuates a snap-action switch at a predetermined set point.
Type E54, E54S, F54, F54S (Bulb & Capillary)
Temperature variations of a liquid  lled sensing bulb are
hydraulically transmitted to a diaphragm which actuates
a snap-acting switch at a predetermined set point.
MAX. TEMPERATURE* LIMITS LISTED ON NAMEPLATE
MUST NEVER BE EXCEEDED, EVEN BY SURGES IN THE
SYSTEM. OCCASIONAL OPERATION OF UNIT UP TO MAX.
TEMPERATURE IS ACCEPTABLE, E.G. START-UP AND
TESTING. EXCESSIVE CYCLING AT MAXIMUM TEMPERATURE
LIMIT COULD REDUCE SENSOR LIFE. CONTINUOUS
OPERATION SHOULD NOT EXCEED THE DESIGNATED
ADJUSTABLE TEMPERATURE RANGE.
* Maximum Temperature - the highest temperature to which a sensing
element may be occasionally operated without adversely aff ecting set
point calibration and 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.
ALWAYS USE A WRENCH ON LOCAL MOUNT, IMMERSION
STEM HEX (SEE PART III DIMENSIONS). DO NOT TIGHTEN BY
TURNING THE DEVICE AS THIS WILL DAMAGE THE SENSOR
AND WEAKEN WELDED JOINTS.
AVOID BENDING OR COILING THE CAPILLARY TUBING
TIGHTER THAN 1/2” RADIUS. EXERCISE CAUTION WHEN
MAKING BENDS NEAR THE CAPILLARY ENDS.
Remove cover (enclosed version only). Cover is held on
by one captive screw located on the front of the cover.
54 Series temperature switches can be mounted in any
position by using either the mounting screw holes on
the bracket or the NPT connection on the immersion
stem (local mounted only). Optional union connectors or
separable well kits are available for remote bulb types.
A 7/8” diameter hole has been provided in the bracket
plate for mounting a standard conduit  tting (See Part
III Dimensions).
For remote mounting, fully immerse the bulb and 6” of
capillary in the control zone. It is generally desirable to
place the bulb close to the heating or cooling source
in order to sense temperature fl uctuations quickly. Be
sure to locate the bulb so that it will not be exposed to
temperatures beyond the instrument range limits.
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.
Installation and Operation Instructions

IMT54 082
DO NOT EXCEED ELECTRICAL RATINGS LISTED ON
NAMEPLATE. OVERLOAD ON A SWITCH CAN CAUSE
FAILURE EVEN ON THE FIRST CYCLE.
For devices with a cover, wire through hole bringing wires
up to the terminals from the rear.
Part II - Adjustments
• 1/4” open end wrench
• Flatblade screwdriver
ENSURE ELECTRICAL CONDUIT ENTRIES ARE PROPERLY
SEALED TO PREVENT MOISTURE ENTRY.
Single Switch Devices
C54, C54S, F54, F54S - no reference dial
To adjust single switch units, follow “High Set” instructions.
For “ne adjustment”, follow “Fine Adjustment”
instructions.
B54, B54S, E54, E54S - with reference dial
Turn the reference dial to desired set point by aligning
setting on dial with dowel pin.
Dual Switch Devices
ON DUAL SWITCH DEVICES, “LOW SET” SWITCH MUST
ALWAYS BE SET EQUAL OR BELOW THE “HIGH SET” SWITCH
(SEE FIGURE 1).
High Set
❶ Immerse the sensing portion of the unit in a calibrated temperature
bath or other calibrated source at the desired “High Set”
temperature.
❷ Allow 5 minutes for the thermal system to stabilize.
❸ 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 clockwise until the
switch transfers, and then counterclockwise until it transfers again.
The “High Set” switch should now transfer on “temperature rise” at
the bath temperature.
❹ If it is desired that the switch transfer on “temperature fall” at the
bath temperature, turn the main adjustment screw clockwise until
the switch transfers again.
Low Set
❶ Lower the temperature of the calibrated bath (or use another
bath) to the desired “Low Set” temperature, and allow 5 minutes for
the thermal system to stabilize.
❷ Using a 1/4” open end wrench, slowly turn the low set 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
at the bath temperature on “temperature fall”.
❸ If it is desired that the “Low Set” switch transfer on “temperature
rise” at the bath temperature, turn the low set adjustment screw
counterclockwise until the switch transfers.
Fine Adjustment
❶ If it is necessary to “ne adjust” the “High Set” setting, raise the bath
temperature to a value slightly higher than the “High Set” temperature.
❷ Note the temperature at which the switch transfers (on rise).
❸ Lower the bath temperature and note when switch transfers
again (on fall). Turn the main adjustment screw clockwise to raise or
counterclockwise to lower the settings.
❹ If necessary, perform the same “ne adjustment” procedure
outlined above for the “Low Set” switch.
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.
