modulating valve Electric ActuatorUsed in valves which stroke20mm.Rating force 500N/ 1000Nl Actual force: 500N 700N/ 1000N 1200Nl 24VAC/ 220VAC can be selectedl Moter with magnetic clutch can output force steady torquel 2K resistance or SPDT feedback available (only 3-position control type)l Control signals: 0 or 2 10VDC and 0 or 4 20mA(only proportional control type)Flow character can be changed betweenequal-percent and equal-linear by the 1st switch on S2 onPCB. when leaving the plant, the flow charater is equal-linear, Controls singnal: 0(2) 10VDC, 0(4) 20mAIn order to confirm the valve's stroke between 0% and 100%, the self-stroking step is necessary.After assemblling TR500-X../TR1000-X..actuator with TL…,TW… or TF... valve body, connect AC24V power supply. Then press down "self -stroking" button on PCB over 3 seconds until the running light flickering:– Self -stroking step starting– The actuator moving to 1 (actuator axes retracts until up limit position), running light flickering–The actuator moving to 0 (actuator axes extends until down limit position), running light flickering–written the result in CPU, self -stoking step is finished ( total process need approx.180 seconds)– If the control singal increasing, running light show green (actuator axes extends)– If the control singal decreasing, running light show red (actuator axes retracts)S2SwitchFunctionDescription1Flow characterONLOG: equal-percentageOFFLIN: equal-linear2Starting of input/output signalON20%:the starting input / output signal is 20% (namely 4 20mA or 2 10V)OFF0:the starting input / output signal is 0 (namely 0 20mA or 0 10V)3Type of input signalONII: input current signalOFFUI: input voltage signaL4Type of output signalONIO: Output current signaLOFFUO: Output voltage signal5Operating modeONDA:DA mode (when input signal is increasing, the actuator axes extends )OFFRA: RA mode (when input signal is increas ing, the actuator axes retracts)6Losing input signal modeONDW: When lose input signal (voltage type), the minimum control signalWhen lose input signal (current type), the minimum control signalOFFUP: When lose input signal (voltage type), the maximum control signalWhen lose input signal (current type), the minimum control signal7Output signal modeONDF: when the actuator axes retracts to limit position,output signal will be minimum value when the actuator axes extends to limit position, output signal will be maximum valueOFFRF: when the actuator axes extends to limit position, output signal will be minimum value when the actuator axes retract to limit position, output signal will be maximum value8SensitivityONHS:thehighsensitivityofinputsignal1.5%OFFLS:thelowsensitivityofinputsignal2%
