0-10VDC
page 1 of 3
Allows user to configure the pump to respond proportionally to a 0-10VDC analog signal. The pump’s
speed varies according to the level of the 0-10VDC signal. The response to the signal can be scaled or
inverted (refer to Diagram 1, 2 & 3).
When operating in an inverted response curve where the minimum signal is associated with the
maximum pump speed, the pump will run at the maximum set speed if the signal is lost. It is extremely important to
properly set the alarms to prevent overfeed on a loss of signal. The user must enter the minimum signal set point above
zero (for example, 0.1VDC) so that a low signal alarm is enabled at 0VDC.
To customize the pump response, set the signal values and the pump speed percent for the high and low range of the
signals (refer to Diagram 1).
The signal level and associated speed set points can be set to any level, as long as there is at least 1VDC difference
between the minimum and maximum signal level and a 10% difference in the speed percent between the two points
(refer to Diagram 3).
