Note:when the value to open by the clearance,the value position potentiometer center tap on to GND The absolute value of voltage change should be from small to big.

In order to ensure implementation of automatic control of  positioning  accuracy, sensitivity should be the scope of regulation.Sensitivity range of small,precision positioning High,but prone to oscillation; sensitivity range,not prone to oscillation,but the poor positioning accuracy.Regulation of “sensitivity”Potentiometers can be a compromise between the two so that it does not produce oscillation adjustment value for the best.

Note:This product is used by the potentiometers are precision multi-turn potentiometer(which can rotate about 25 laps).Also,module 10 on the 16th to terminalcan not access any other power, “lost letter” selcetor switch can not be assigned to “ON” position otherwise they will be Damaged module.

“Zero” “4mA” “20mA”potentiometer clockwise rotation is the output signal increases, counter-clock wise rotation Reduce the output signal, such as found in the above-mentioned potentiometer clockwise,the output signal decreases, I would be grateful if in addition to valve position potentiometer center tap  Exchange outside the two lines lock.

Note:The factory used by the precision potentiometers are multi-turn potentiometer  can rotate about 25 laps.

为了保证执行器在自动控制中的定位精度，必须调节灵敏度。灵敏度小,定位精度高，但容易产生振荡；灵敏度大，不容易产生振荡，但定位精度差。调节“灵敏度”电位器可在二者之间取折衷，使其不产生振荡为最佳调节值。

现场控制：将控制开关切换至“现场”位置，然后按“关”、“开”按钮即可实现对执行器的关、开控制。

远程控制：将控制开关切换至“远方”位置，即进行远程控制

In order to ensure the implementation of automatic control of positioning accuracy, we  must adjust the sensitivity. Sensitivity of small, high positioning accuracy, but Prone to  oscillation; sensitivity, and can not be late to produce oscillations, but the poor positioning  accuracy. Regulation of 'sensitivity" can be both potentiometers told between the sorrow,  it does not produce oscillation adjustment value for the best.

Scene control:  the control switch to "live"location, and then press"off ”,"open" button  to achieve the implementation of related devices, the control.

 Remoto Control: the control switch to "remote" location, that is, remote control straight.
