Clients' questions about proportional valve

GR, green wire 4-20ma signal input.
YW, yellow wire, ERR signal output, when valve is blocked, multimeter, the current file can be measured.
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

What is Modulating valve 4-20ma 0-5v, 0-10v, PWM voltage of position frequency output?

When working voltage is:DC24v, Modulating valve 4-20ma 0-5v, 0-10v, PWM wire voltage Plus the voltage, usually 3v, 5v
