The pump will be pumping water into the vat to maintain the levelbetween 100 m 3 and 10 m 3 . The feedback signal is 0 to 20 mA. At 5 m 3 the feedbacksignal is 0 mA, and at 100 m 3 the feedback signal is 20 mA. A 0 to 10 V signal isused for the setpoint. At 0 V the process level is 100 m 3 , and at 10 V the process levelis 10 m 3 .1. Select YES, SET POINT in the PI Regulator menu.2.
