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 Tonheflow is a manufacture in China specilized in mini motorized shut off ball valve (1/4"~2'').And valve actuator which are approved CE certification and SS valve approved NSF61 international certification.we buy a PICC insurance for our products in 2016.
