11.8.3 connection examples
Design Envelope pumps can be configured in four main ways:
i Sensorless
ii Closed loop – with feedback sensor
iii Constant curve mode – Potentiometer Control
iv Constant curve mode – bms signal
iv.i Full speed override
i sensorless
Design Envelope pumps are factory configured to be
connected as shown below.
ii closed loop – with sensor feedback
To control the pump based on a 4-20mA feedback signal
from a sensor use the following connection.
