Hi, I have a gas valve Woodward GS16 1.50 SQIN Change Level: G Part Number: 9907-561 Serial: 19481553

I'm having this error:
AnalogInputLowErr (Output) – If the analog input is not connected, an analog input low error (< 2 mA) will shut down the valve.

The problem is 4mA is connected to the valve. Through VPC Service Tool I see: Analog Set Point: -21.13%. Please check images.

Do you think is a calibration's problem?
Is it a valve terminal block problem?
Which is the correct version for this kind of valve?


Best Regards

 

the analog set position is an input to the valve controller, and typically
a positive signal.
