11.8.3 connection examples
ivs Sensorless pumps can be confi gured 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
ivs sensorless pumps are factory confi gured 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.
