12 SERIES FOR USE IN CLASS I, DIV. 1, GROUPS A, B, C & D; CLASS II, DIV. 1, GROUPS E, F & G; CLASS III HAZARDOUS LOCATIONS. ENCLOSURE TYPE 4X, IP66. AMBIENT TEMPERATURE RANGE -50°C (-58°F) TO 95°C (203°F).

ATEX AND IEC SPECIFIC CONDITIONS OF USE : THE WIRING
TO THE PRESSURE SWITCH MUST ONLY BE CONNECTED IN A SAFE AREA OR BY AN APPROVED TERMINAL BOX CERTIFIED TO EN 60079-0/IEC 60079-0, EN 60079-1/IEC 60079-1, AND EN 60079-31/IEC 60079-31 FOR HAZARDOUS LOCATIONS. THE EPOXY RESIN SHALL NOT BE SUBJECTED TO A TEMPERATURE GREATER THAN 125°C (257°F).

THE WIRES SHALL BE PROTECTED AGAINST MECHANICAL DAMAGE, E.G., BY USE OF CONDUIT. OPTION M515 WITH DIN CONNECTOR IS NOT COVERED BY THIS CERTIFICATE. OPTION M460, EXTERNAL EARTH GROUND SCREW, IS TO BE USED IF METAL CONDUIT IS NOT USED. ELECTRICAL CONDUIT FITTING THREADED CONNECTION SHALL BE M20 X 1.5 WITH 7 THREADS MINIMUM ENGAGEMENT.

UE declarations and third-party issued Agency certifi cations are available for download at www.ueonline.com.

PRIOR TO INSTALLATION, CHECK THE WETTED PARTS MATERIAL FOR COMPATIBILITY TO THE PROCESS MEDIA.

THE DUAL SEAL DEVICE METHOD OF PRIMARY SEAL FAILURE ANNUNCIATION IS VISIBLE LEAKAGE FROM THE ENCLOSURE. DEPENDING UPON MEDIA SENSED, ADDITIONAL METHODS OF LEAK DETECTION SHALL BE REQUIRED.

THIS PRODUCT DOES NOT HAVE ANY FIELD  REPLACEABLE PARTS. ANY SUBSTITUTION OF COMPONENTS SHALL INVALIDATE AGENCY CERTIFICATION(S), AND IMPAIR SUITABILITY FOR CLASS I, DIV. 1 LOCATION.

PROOF PRESSURE * LIMITS STATED IN THE LITERATURE AND ON NAMEPLATES MUST NEVER BE EXCEEDED, EVEN BY SURGES IN THE SYSTEM. OCCASIONAL OPERATION OF UNIT UP TO PROOF PRESSURE IS ACCEPTABLE (E.G., START-UP, TESTING). CONTINUOUS OPERATION SHOULD NOT EXCEED THE DESIGNATED OVER RANGE ** OR WORKING PRESSURE 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.
•  Over Range Pressure – the maximum pressure to which a pressure sensor may be continuously subjected without causing damage and maintaining set point repeatability.
• Working Pressure Range – the pressure range in which two opposing sensors can be safely operated and still maintain set point provided the difference in pressure between the low and high sides does not exceed the designated adjustable range.

The 12 Series switch utilizes a diaphragm or a piston sensor to detect a pressure change. The response, at a predetermined set point, actuates a  SPDT or DPDT snap-acting switch, converting a pressure signal into an electrical signal. Control set point may be varied by turning the internal slotted adjustment screw according to procedures outlined in Part II-Adjustments. Please refer to product datasheet at www.ueonline.com for product specifications. Date code format on nameplate is “YYWW” for year and week.

DEVICE MUST NOT BE ALTERED OR MODIFIED AFTER SHIPMENT. CONSULT UE IF MODIFICATION IS NECESSARY.

Part I – Installation

Mounting

1 1/16” Open end wrench

• 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.

NOTE : Due to product sensitivity on sensor Type W, it is recommended that these models be mounted vertically with pressure connection facing down. Other types of mounting may cause slight set-point shifts, which may require readjustment.

• 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.
• FOR DIFFERENTIAL PRESSURE MODELS, MOUNT USING THE ATTACHED MOUNTING BRACKET AGAINST A RIGID SUPPORT, AND THEN CONNECT LOW AND HIGH PRESSURE PORTS.
• IF USING WITH A JUNCTION BOX, IT IS RECOMMENDED THAT THE PRODUCT BE MOUNTED VERTICALLY WITH THE PRESSURE CONNECTION FACING DOWN.
• If  product is to be set after mounting, verify that adjustment opening is accessible, “Front” marking on nameplate facing operator.
  
  

Panel Mounting via 1/2” NPTM or M20 Electrical Connection
When panel mounting, mount through 7/8” clearance hole in panel. Use 1/2” or M20 conduit nut to secure in place. Always support the product by holding a wrench on the hex.

Surface Mounting Bracket Kit (P/N 62169-13) (see Fig. 6)

1. Open the adjustment cover and orient the unit so that adjustment opening will be accessible when the switch is mounted.
2. Close the adjustment cover ensuring that the bracket does not interfere with the cover as this serves as the Dual Seal device method of primary seal failure annunciation and venting.

Failure to install the unit correctly with the mounting bracket may result in improper venting of the adjustment cover.

Wiring

• DISCONNECT ALL SUPPLY CIRCUITS BEFORE WIRING UNIT. WIRE UNITS ACCORDING TO NATIONAL AND LOCAL ELECTRICAL CODES. THE WIRES SHOULD BE PROTECTED AGAINST MECHANICAL DAMAGE BY USE OF A CONDUIT OR OTHER SUITABLE MEANS.
• DO NOT EXCEED ELECTRICAL RATINGS LISTED ON NAMEPLATE. OVERLOAD ON A SWITCH CAN CAUSE FAILURE, EVEN ON THE FIRST CYCLE.
• DIN CONNECTOR (OPTION M515, FIGURE 4) IS NOT APPROVED FOR CLASS I, DIV. 1 HAZARDOUS LOCATIONS/FLAMEPROOF ATMOSPHERES.

1/2” NPT (male) or M20 (male) conduit connection is provided on top of the product with 72” long, 18 AWG leadwires. The product is available with SPDT or DPDT operation. External grounding screw and clamp is provided with option M460 for ATEX installation with non-metallic conduit systems (See Figure 2). To attach conduit connection hold electrical connection steady with wrench on hex, then thread on conduit.

Factory Sealed Leadwires are color coded:

DIN Connector with 4 Male Terminals (see Figure 4)
Connector conforms to DIN 43650. Use a female mating DIN connector (not UE supplied).

Coding: TERMINALS

Part II – Adjustments

Flathead screwdriver with 3/16” or 1/4” wide blade

1. Connect control to pressure source.
2. With power disconnected, slide cover toward electrical terminations while twisting it to overcome friction.
3. Connect power to terminals or leads.
4. Insert screwdriver into adjustment slot and turn clockwise to increase setting or counter  clockwise to decrease setting (See Figure 3).
