Monitoring (IAW®): Can detect sensor open or short circuit; plugged port; power supply out of range; overload or normal load condition; microprocessor failure; keypad short circuit; switch failure, etc. Output state: 2-state or 3-state operation mode can be selected on site. 2-state operation: (default setting) During normal operation, the output maintains one state (open or closed); i.e. rise/close or fall/close for normally open and rise/open or fall/ open. NOTE: Switches must be normally closed (raise/open, fall/open) during diagnostic tests and other error conditions.3-state operation: During normal operation, the output remains off; ie rising/pulse or falling/pulse. If it turns on, an error is present; different pulse rates are available depending on the model. Fast or slow type can be selected. See the installation manual for details. Control mode: Field can change the output state, or change the rising or falling setpoint. Automatic or manual reset can be set. Analog output: 4-20mA output, maximum 700ohms 24VDC, field calibrated, 2:1 turn down ratio. Capable of displaying various error conditions at 0, 3.5, 22 and 24 MA ranges. See the installation manual for details. (2WLP, 2XLP, 8W2D, 8X2D models only) Electrical Characteristics: (2-wire models only) Housing: 4X/IP66, aluminum epoxy coated. Dial: Polycarbonate pressure-sensitive keypad and display resistant to UV damage. Cover: Epoxy coated aluminum with tempered glass interior (Ex series models only). Electrical interface: 1/2"NPT internal thread stainless steel interface; 3/4"NPT external thread cast aluminum interface (only explosion-proof series models). Displays: • On-site 4-digit x0.5” LCD • Reset Status • I'm Working (IAW®) • Setpoint • Process Variation • Deadband Value • Switch Evaluation • Min/Max • Switch Status • Error Code Setpoint & Dead zone: user set, 100% full scale adjustable.Memory: Equipped with non-lost data memory to ensure the security of programming and data. Effective transmission distance: 2W2D/2X2D and 2W3A/2X3A can reach an effective transmission distance of 2000 feet. Sensor: Pressure Switch - 316 Stainless Steel Welded Diaphragm, 1/2" NPT Female Port. Media Temperature: -40 to 257°F (-40 to 125°C) Differential Pressure Switch - 316 Stainless Steel, Welded Diaphragm, 1/2 4" NPT male interface. Media Temperature: -40 to 257°F (-40 to 125°C) Temperature Switch - 316 Stainless Steel, 0.25” diameter, 100ohm 4-wire Platinum RTD. Media Temperature: -300 to 1000°F (-184 to 538°C ) Vacuum resistance: All pressure sensors can withstand vacuum without recalibration. Emission standard: According to EN 55011 class A, EN 61000-3-2 standard emission. EMI/RFI: Meet CE, EMC requirements: EN 55011, EN61326, EN61000-6-2 Other features: EN 61000-3-3 against voltage fluctuations and momentary voltage changes. EN 61000-4-2 against static electricity. EN 61000-4-3 against continuous radiation interference. EN 61000-4-4 against Momentary changes in current. EN 61000-4-5 Protection against shock pressure. EN 61000-4-6 Protection against continuous conducted disturbances. EN 61000-4-8 Protection against electromagnetic disturbances. EN 61000-4-11 Protection against voltage dips or interruptions. Weight : 2W, 4W, 8W: 1.5 - 1.9 lbs (0.7 - 0.9 kg)2X, 4X, 8X: 4.5 - 6.0 lbs (2.0 - 2.7 kg) Shock Resistance: 15g for 10ms, 40g for 4ms. The influence is less than +/- 0.40% of the whole range Vibration resistance: According to the standard of IEC 61298-3, in the range of 10-1000HZ, the influence is less than +/- 0.40% of the whole range Performance characteristics of ONE series pressure switch Self-diagnosis detection function port Blockage detection Anti-nuisance alarm function Patent-pending electronic IAW® self-monitoring function Min/max memory Large display. Set point and deadband are 100% adjustable. No loose parts design, suitable for high vibration environment. There are explosion-proof, intrinsically safe and general-purpose switches suitable for high-risk areas. Comply with SIL 1 & 2 safety system US UE electronic pressure switch applications: • Pumps and compressors - start / stop, optimize treatment, shutdown • Lubricant oil monitoring - oil tank temperature, bearing pressure, pre-maintenance. •Hydraulic oil pressure - high pressure monitoring, emergency shutdown. •Filter Monitoring - Automatic flushing, indication of clogging and abnormal conditions, providing flow values. • Security System - Level 1 & 2 for complete security, alarm and shutdown, on-site alarm switch, fast reaction time. • Plant equipment upgrades – upgrades to power plants and sewage treatment plants to replace mechanical switches.
