This control occurs at two places on the reservoir: The UDC configuration described is a level control wherein the object of the control loop appears to be: The ‘Rng1’ error your getting refers to the analogue input UDC’s are twin-loop controllers though in your application loop 2 is disabled It shows that error when the input range goes above 20ma or below 4ma.

So that i can help you to resolve the problem.

Could this be a span problem? Put the controller in manual and wind the output up and down while watching the measured value. Username Password Remember me on this computer. Adjust the head gate position to maintain reservoir level. SPHiLim is the parameter that determines how high the setpoint on the controller can be wound up to.
