Operation instructions

High performance industrial computer kernel, large torque output, can drive DN8-DN32 calibre ball valve;

Input 4~20mA control, feedback 4-20ma signal;

Control accuracy: 0.5%~1%;

Electric actuators have two kinds of working status: automatic state (input signal control switch),
manual state (key control switch);

1. In manual mode, no operation for 30 seconds, automatic return to automatic mode, receiving input
4~20mA signal control;

2. When the input signal is broken, or the signal is lower than 3mA (the standard is the lowest,
normal is 4mA), the warning of “OFF” is displayed;

3. Automatically eliminate the input signal of the input signal below 4mA or greater than 20mA due
to abnormal reason to stop the valve operation;

4. In the automatic state, you can check the input signal size at any time (in the form of percentages,
such as 12mA display is 50%), so as to facilitate on-site debugging;

5. Press the button 1 to switch “automatic/manual” mode, and the opening displays the flicker when the
representative switches to manual mode, which can be manually adjusted;Once again press the button 1,
the opening display stop flicker, switch to automatic mode;

6. In manual mode, press the button 2 to open the valve, release the key or open the position valve
to stop automatically;

7. In manual mode, press the button 3 to close the valve, release the button or close the valve
to stop automatically.
