You must be a Control. You have given some good problem definition. The set point should be the desired level of the reservoir. The bound manual you are looking for is Product E.
What I need to identify is the honeywepl that drives the output. This control occurs at two places on the reservoir: Your subscription request is being processed. Could this be a span problem?
Some tips for better search results By Patti on 4 November, – 2: You have clicked on the “? The inlet control is likely configured for reverse operation increaed level decrease output, close gate. Adjust the head gate position to maintain reservoir level. 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 uddc goes above 20ma or below 4ma.
