UK Rotork actuator 

 【Product Name】 IQ Series 
 DESCRIPTION rotork produced electric actuator in the valve control is a world leader, IQ family of products is not the first set using infrared openings debugging, reliable double-sealed structure can dive 3 Mida 72 hours, many protection feature allows the product to become synonymous with reliability. 
 【Features】 1, lifetime use: no matter what the environment, any application, IQ double-sealed waterproof shell and a comprehensive protection system, fully protected within the device. 
 2, debugging is simple: non-invasive infrared setting, convenient and simple, according to the user as with the use, quick to set and modify parameters. 
 3, double-sealed double protection: protection class IP68 --- underwater 7 m 72 hours, completely waterproof, dustproof, and close airtight. 
 4, torque measurement: Torque measuring device patented, advanced technology, not the frequency, voltage and temperature changes, can be accurate, repeatable measurement of torque. 
 5, position measurement: patented non-contact valve position by measuring system, the valve is easy to determine the exact position and end position becomes very simple. 
 6, remote diagnosis: the use of IrDATM fast, safe, non-intrusive communication and data exchange, data can be analyzed on the actuator and gives recommendations. 

 [Basic functions] 1, phase synchronizer: automatically correct phase sequence and phase loss protection. 
 2, thermal protection: Motor winding thermal relay can be detected within the coil temperature, when the temperature exceeds a predetermined value, disconnect the control loop. 
 3, valve jammed protection: If the valve is stuck, when you start after 7 seconds without action, the circuit will automatically disconnect. 
 4, instantaneous reversal protection: automatic time delay circuit to handle the instantaneous reverse order, to prevent shock. 
 5, the data records: each has a data logger can record the history of torque, frequency, status and date, can be real-time query, analysis, diagnosis. 

 Technical index 1, local control 
 1), the electrical box cover to provide non-invasive control knob, red for the Local / Stop / Remote selector switch three-state, the black knob to place open or close the valve electrically operated switch. 
 2), local control device can also be set with IQ at 0.75 meters for open / close / stop operation. 
 2, remote control switch 
 1), the use of optically isolated interfaces, usually positive switching (also available negative switching) 
 2), external users control power: range 20-60V AC / DC or 60-120V AC 
 3), actuator to provide control power: 24V DC 
 4), each side of the pull-down power control: 
 24V DC when 5mA 120V AC 12mA when 
 5), the minimum voltage of 20V when switched on 
 Disconnect the maximum voltage of 3V 
 Shortest time of 300ms signal 
 The core of the largest cable capacitance: 2uF 
 3, remote analog control 
 1), increased alternative board - the proportion of the control panel, users can control 4-20mA analog. 
 2) Accuracy: 1% 
 3), the dead zone: adjustable 0-9.9% within the whole trip 
 4), input impedance: 250Ω 
 5), corresponding to the input signal can be any valve position. 
 4, the output signal 
 1), provides four passive, single-pole lockable contacts S1, S2, S3, S4, each contact device can be set using the IQ alone 
 Li is set to one of the following signals; each contact can be set to "always" or "normally closed" contact capacity 
 5mA-5A 120V AC or 30V DC. 
 a, valve 
 Fully open, fully closed position (accurate) or any intermediate position (0-99% open) 
 b, state 
 Valve opening, closing, running, choose the place to stop, choose local, choose the remote, open or 
 Chain starts off valves, emergency protective boot and so on. 
 c, alarm valve 
 Motor tripped on torque in mid travel, motor fully open or fully closed position in the jump-off torque, the actuator is handwheels. 
 d, the alarm actuator 
 Lost phase, loss of internal 24V DC battery voltage is too low, the thermostat tripped. 
 2) to provide a monitoring relay, the relay is passive, reversible independent relay contact capacity of 5mA- 
 5A, 120VAC or 30V DC, with one or more of the following circumstances, the relay will disconnect: 
 a, single or multi-phase power-down 
 b, control circuit power failure 
 c, the switch is in place or stop position 
 d, motor temperature protection device tripped. 
 5, the analog signal 
 1), remote valve analog display - CPT 
 Current Position Transmitter (CPT) provides an internal power supply and the valve position proportional 4-20mA analog signal, can be 
 Choose the minimum signal corresponding to the valve closed or opened, and automatically set the zero and full scale, output impedance 500Ω, can 
 Repeatability and linear in the valve full stroke ± 1% or less. 
 2), remote valve operating torque of the analog display - CTT 
 Current Torque Transmitter (CTT) provides an internal power supply, and the actuator output torque (rated torque of 0 - 
 120%) non-contact proportional 4-20mA analog signal. When the valve is stationary, CTT's output will indicate when a continuous 
 Before the torque value.
