52 m-530dun-gb-0119 Analog modeIn this remote operating mode the flow rate will be proportional to the external milliamp or voltage signal inputreceived by the pump. The relationship between the external analog signal and the flow rate is determined byconfiguring the two points A and B as shown in the graph below. The rate of flow can be proportional orinversely proportional to the analog input.The default values stored in the pump are A (5mA, 0 rpm) and B (19mA, 220 rpm).When the analog signal received is greater than the level defined by point A, the run status output will beenergised as the pump is running.To select Analog mode select MODE. Using the ∧ /∨ keys, scroll to Analog and press SELECT.The analog signal being received by the pump is displayed, for information only, on the INFO screen. PressINFO to display this information.
