OCCASIONALOPERATION OF THE PRODUC T UP TO PROOF PRESSURE ISACCEPTABLE (E.G., START-UP, TESTING). CONTINUOUS OPERATION SHOULDNOT EXCEED THE DESIGNATED OVER RANGE PRESSURE** OR WORKINGPRESSURE RANGE***.*Proof Pressure - the maximum pressure to which a pressure sensor may beoccasionally subjected, which causes no permanent damage (e.g., start-uptesting). The product may require set-point adjustment after reaching proofpressure.**Over Range Pressure - the pressure value to which a pressure sensor may becontinuously subjected without causing damage and while maintaining setpoint repeatability.***Working Pressure Range - the pressure range within which two opposingsensors can be safely operated while maintaining set point repeatability.THE EPOXY RESIN SHALL NOT BE SUBJEC TED TO A TEMPERATUREGREATER THAN 125°C.THIS PRODUC T DOES NOT HAVE ANY FIELD REPLACEABLEPARTS. ANY SUBSTITUTION OF COMPONENTS WILL INVALIDATETHIRD-PARTY ISSUED APPROVALS AND CERTIFICATIONS, ANDMAY IMPAIR SUITABILITY FOR CLASS I, DIVISION 1 LOCATION.The 12 Series switch utilizes a diaphragm or a piston sensor todetect a pressure change. The response, at a predetermined setpoint, actuates a SPDT or DPDT snap-acting switch, converting apressure signal into an electrical signal. Control set point may bevaried by turning the internal slotted adjustment screw according toprocedures outlined in Part II-Adjustments.12 SeriesExplosion-Proof, Pressure,Vacuum, and DifferentialPressure Switches U N I T E D E L E C T R I CC O N T R O L SInstallation and MaintenanceInstructionsIMP12-16Please read all instructional literature carefully and thoroughly before starting.
