What does Pump-1 exceeds the maximum operating point specified for the pump curve means? And how do I correct this error?
This is usually due to a problem in the model such as
1. Excessive demand in that pressure zone
2. Tank water level in the discharge side tank being too low or suction side tank being too high
3. An open loop in the network where you are pumping from the discharge side of the pump around to the suction side.
This message is more often a sign of network problems even though it shows up at the pump.
In addition to what Tom has stated, this wiki link below includes additional information on how to resolve the user notification:
