United Electric Controls 100 Series, B100, C100, E100, F100 Installation And Maintenance Instructions Manual

GENERAL
The 100 Series temperature switch utilizes either a liquid filled sensing stem (immersion stem, direct mounting) or liquid filled sensing bulb (bulb & capillary, remote mounting) to detect a temperature change. The response at a pre-determined set point actuates a SPDT snap-acting microswitch, converting the temperature signal into an electrical signal. Control set point may be varied by turning the internal adjustment hex (C100, F100) or reference dial (B100, E100) according to the procedures outlined (See Part II – Adjustments).
MAXIMUM TEMPERATURE* STATED IN LITERATURE AND 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, TESTING). CONTINUOUS OPERATION SHOULD BE RESTRICTED TO THE DESIGNATED ADJUSTABLE RANGE.
*Maximum Temperature - the highest temperature to which a sensing element may be occasionally operated without adversely affecting set point calibration and repeatability.

Tools Needed
Adjustable wrench
Flathead screwdriver
Hammer (for alternate wire knockouts)
MOUNTING
ALWAYS LOCATE UNITS WHERE SHOCK, VIBRATION AND
TEMPERATURE FLUCTUATIONS ARE MINIMAL. DO NOT MOUNT
UNIT IN AMBIENT TEMPERATURES EXCEEDING PUBLISHED LIMITS.
UNIT MAY BE MOUNTED IN ANY POSITION PROVIDED THE ELECTRICAL CONDUIT IS NOT FACING UP. THE RECOMMENDED MOUNTING POSITION IS VERTICAL (PRESSURE CONNECTION
FACING DOWN), SPECIFICALLY WHERE HEAVY CONDENSATION IS EXPECTED.
For remote mounting, mount the unit via the (2) 1/4” screw clearance holes on the enclosure (See Dimensions on back page.) Fully immerse the bulb and 6” 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 fluctuations quickly. Be sure to locate the bulb so that it will not be exposed to temperatures beyond the instrument range limits.
ALWAYS HOLD A WRENCH ON THE TEMPERATURE HOUSING
HEX WHEN MOUNTING UNIT. DO NOT TIGHTEN BY TURNING
ENCLOSURE. THIS WILL DAMAGE SENSOR AND WEAKEN
SOLDERED OR WELDED JOINTS.
On models supplied with an external manual reset button, be sure to leave sufficient finger space over the reset button for the operator to reset the control.
WIRING
DISCONNECT ALL SUPPLY CIRCUITS BEFORE WIRING UNIT. WIRE UNITS ACCORDING TO NATIONAL AND LOCAL ELECTRICAL
CODES. MAXIMUM RECOMMENDED WIRE SIZE IS 14 AWG. THE RECOMMENDED TIGHTENING TORQUE FOR FIELD WIRING TERMINALS IS 7 TO 17 IN-LBS.

Please read all instructional literature carefully and thoroughly before starting. Refer to the final page for the listing of Recommended Practices, Liabilities and Warrantees. For functional safety applications, please refer to the safety manual which can be downloaded from www.ueonline.com
Part I - Installation
ELECTRICAL RATINGS STATED IN LITERATURE AND ON NAMEPLATE SHOULD NEVER BE EXCEEDED. OVERLOAD ON A SWITCH CAN CAUSE FAILURE ON THE FIRST CYCLE.
Remove the two screws retaining the cover and cover gasket. A 1/2” NPT conduit connection is located on the left side of the enclosure. Two cast-in 7/8” diameter knockouts for electrical conduit are located on the side and rear of enclosure. These can easily be knocked out by placing the blade of a screwdriver in the groove and tapping shar ply with a hammer.
Connect conduit to the enclosure and wire directly to the switch ter minals according to local and national electrical codes. Bring the wires up to terminals from the rear of the enclosure allowing enough slack so as not to affect switch movement when making setting adjustments. The three switch terminals are clearly labeled “common”, “norm open”, and “nor m closed”. If lead wires are supplied, color coding is as follows:
Manual Reset Option 1530 SPDT
Common (COM) Violet Normally Open (NO) Blue Normally Closed (NC) Black
A grounding screw and clamp (cast in symbol) is provided which meets a 35 lb. pull test. Keep the wire as short as possible to prevent interference with the plunger and, if applicable, the optional adjustable deadband switch wheel (option1519).
Tools Needed
3/16” open end wrench
NOTE: For set point adjustments and recalibration, immerse sensor (immersion stem or bulb and 6" of capillary) in a calibrated temperature source and stabilize unit.
Types C100 and F100
Remove cover. Switch has a hex adjustment screw inside enclosure (See Figure 1). If switch transfer point differ s from actual temperature, adjust setting. To raise the temperature setting, turn the hex towards the left (clockwise). To lower the temperature setting, turn the screw towards the right (counter-clockwise). When making adjustments, do not exceed the maximum temperature rating on nameplate.
Types B100 and E100 (with reference dial)
Controls are factory calibrated for maximum accuracy at the midpoint of the scale.
To re-calibrate, turn dial to desired set point(See Figure 2). If the actual temperature and set point temperature do not agree, turn hex adjustment screw towards the left (clockwise) to raise and towards the right (counter­clockwise) to lower temperature setting.
Types with Adjustable Deadband Switch (Option 1519)
Types with option code 1519 incorporate a snap switch with integral adjustment wheel. Turning this wheel raises or lowers the temperature rise set point. The fall set point remains constant. To use the adjustable deadband switch:
To increase deadband, turn the adjustment wheel left. This increases the rise set point while keeping the fall set point constant.

RECOMMENDED PRACTICES AND WARNINGS
United Electric Controls Company recommends careful consideration of the following factors when specifying and installing UE pressure and temperature units. Before installing a unit, the Installation and Maintenance instructions provided with unit must be read and understood.
• To avoid damaging unit, proof pressure and maximum temperature limits stated in literature and on nameplates must never be exceeded, even by surges in the system. Operation of the unit up to maximum pressure or temperature is acceptable on a limited basis (e.g., start-up, testing) but continuous operation must be restricted to the designated adjustable range. Excessive cycling at maximum pressure or temperature limits could reduce sensor life.
• A back-up unit is necessary for applications where damage to a primary unit could endanger life, limb or property. A high or low limit switch is necessary for applications where a dangerous runaway condition could result.
• The adjustable range must be selected so that incorrect, inadvertent or malicious setting at any range point cannot result in an unsafe system condition.
• Install unit where shock, vibration and ambient temperature fluctuations will not damage unit or affect operation. When applicable, orient unit so that moisture does not enter the enclosure via the electrical connection. When appropriate, this entry point should be sealed to prevent moisture entry.
• Unit must not be altered or modified after shipment. Consult UE if modification is necessary.
• Monitor operation to observe warning signs of possible damage to unit, such as drift in set point or faulty display. Check unit immediately.
• Preventative maintenance and periodic testing is necessary for critical applications where damage could endanger property or personnel.
• Electrical ratings stated in literature and on nameplate must not be exceeded. Overload on a switch can cause damage, even on the first cycle. Wire unit according to local and national electrical codes, using wire size recommended in installation sheet.
• Do not mount unit in ambient temp. exceeding published limits.
