Pressure Independent Control Valve ---PICV TPL...Series

Transcription

1 Rev.C Pressure Independent Control Valve ---PICV TP...Series Features Introduction High Control Precision Both the electric valve core and balancing valve core adopt straight travel design. Compared with rotary design, straight travel has higher control precision. ow eakage Rate The leakatge rate is no more than 0.02% of Kvs. Build-in Diaphragm Capsule and Connecting Pipe The valve adopts the build-in diaphragm capsule and connecting pipe. It can avoid damaging during installation compared with external connecting pipe. Anti-blocking Design The balance structure of spring diaphragm significantly reduces the probability of blocking in valve body. Because of the lower requirement for water quality, it can easily deal with the water in heating pipeline. High-quality Material The valve body is made of high-quality brass Hpb59-1,the valve stem and valve core are made of high-quality stainless steel. Tiger Controls Equipment Co., td. 1

Made the actuator shaft is concentric with the valve stem which can be observed from the hole,and make these two connecting faces keep coinciding.then clock the two screws on the clip. The two connecting faces of valve stem and actuator shaft should keep coinciding! ote: When we do the pipe pressure testing and flushing, the valve body shoule be in the state of full open, if not, the internal diaphragm of valve body will be damaged and lose the balancing function! 3 Pulling the fixed fitting to the 4 groove and locking by two screws The status after assembled, face and back. Wiring Instruction otes: 1. Open the cover when wiring,prohibit to disassemble other spare parts! 2. Carefully check the power voltage when wiring, wire according to the product parameter, if not, it may cause fire and endanger personal safety in servere case! 3. Please cut off power supply when wiring in order to ensure personal safety! 4. After wiring, please install the cover to the origional position, avoid electric shock for the terminal! 1.Open the cover and prepare to wire. 2.Wire correctly according to the wiring diagram. a.24v Terminal Diagram S1 Functional DIP Switch Functional Terminal Proportional Terminal 3-position Terminal SPDT Feedback Terminal b.220v Terminal Diagram S1 Functional DIP Switch Functional Terminal Power Terminal 3-position Terminal Proportional Terminal SPDT Feedback Terminal Tiger Controls Equipment Co., td. 3

Connect actuator and valve body. B. Wiring power and control signal wires. C. Set DIP Switch to needed position. After the setting, turn on power of actuator, pre-setting function will come into effect. (DIP Switch can be set with power) D. Power on the actuator. E. Actuator Self-stroking: this step is for matching stroke of actuator and valve. 1) The Reset yellow indicating light will keep flashingng (frequency is 1Hz),actuator shaft extends to lower limited position firstly and then, it retracts to upper limited position, actuator will not be controlled by signal by this time. 2) After 3 minutes, Reset yellow light stop flashing, self-stroking stops and the matching of the valve and actuator is finished. By then, actuator running direction can be controlled by control signal. 3) If the Reset red light is quick flashing(2hz) during the self-stroking, it means the self-stroking status is not correct and the actuator start alarming. The actuator can not match with the valve's max. stroke. Remarks: If self-stroking is needed in a power-on state, press down the Reset button on PCB over 5 seconds, and then the actuator start self-stroking. Self-stroking phenomenon are the same as step (1), (2) above. F. ocal mode:press the button and at the same time over 5s, loosen the buttons and actuator enter into local mode, at that time the, and Reset light will always be on red. If you need actuator shaft retracts, long press, the light will always be on green; If you need actuator shaft extends, long press, the light will always be on green. After reach to the expected position,repress and at the same time over 5s, and then loosen the buttons, it will exit the local mode. ote: 1. The factory default setting is automatic self-stroking, it means that actuator will repeat automatic self-stroking when power on each time! 2. If you don't need automatic self-stroking function, you can set the 7th switch to OFF, it will change into manual self-stroking (Phenomenon as same with (1), (2). Tiger Controls Equipment Co., td. 5

6 Function Introduction Proportional Type /: 0~10VDC O OFF S As shown in the left,when equipped with Pressure Independent Control Valve, DIP Switch S1-5 is DA mode: at terminal O,E increasing: actuator shaft retracts, valve stem extends, valve tends to open. at terminal O,E decreasing, actuator shaft extends, valve stem retracts, valve tends to close. at terminal O,E has no changing, actuator shaft and valve stem stay in present position. When voltage (or current) signal is disconnected, this is equivalent to input the min. control signal,actuator shaft retracts, valve closed. Dip Switch Instruction Switch Function S1-1 Starting of control/ S1-2 Type of control signal S1-3 Impedence match of control signal S1-4 Type of feedback signal S1-5 Operating mode S1-6 osing control signal mode Description O 20%:the starting of control/ is 20%(namely 4~20mA or 0~10VDC) OFF 0:the starting of control/ is 0(namely 0~20mA or 0~10VDC) O II:current signal OFF UI:voltage signal O UI:voltage signal OFF II:current signal O IO:current signal OFF UO:voltage signal O OFF O OFF DA:When the control signal increase, actuator shaft extends;when the control signal decrease, actuator shaft retracts. RA:When the control signal increase, actuator shaft retracts;when the control signal decrease, actuator shaft extends. DW:When lose control signal (voltage type or current type), actuator will provide a min. control signal internally. : 1)When lose control signal (voltage type),actuator will provide a max. control signal internally. 2)When lose control signal (current type),actuator will provide a min. control signal internally. S1-7 Self-stroking mode O DF:Power on each time, self-stroking starts automatically. S1-8 Control mode (when S1-9 is OFF) OFF RF:Self-stroking starts only when press the red self-stroking button manually.
