Wire Drawing below:
white wire cannot be directly connected to the power supply. It needs to be connected to the 10K resistance and then connected to the power supply.
GR, green wire 4-20ma signal input.
YW, yellow wire, ERR signal output, when valve is blocked, will output a fault signal.
you can connect a light to YW & RD , the light will turn on.
WT, white wire, PWM signal, can be measured with oscilloscope.
Ask:Is the ERR Signal an 5V Level?
Or the same voltage as the rated voltage DC9-24V?
Anwser:
YW, yellow wire, wrong signal line, when it is blocked, multimeter, the current gear can be measured.
Using current gear(proper current gear),
Not a voltage
Company introduction
When you inquiry the valve, pls confirm the detail technical data :
1, valve size , materail
2, working voltage DC9-24v?
3, signal control 4-20mA? 0-5V? 0-10v?
4, actuator cable length 0.5m? 1.5m?
