Please kinde note:
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
