10 PUMP CONTROL SET-UPS
10.1 SelfSensing Description
The Taco SelfSensing pump is a Taco pump equipped
with a variable frequency drive (VFD) with SelfSensing
control technology. SelfSensing control is an innovative
concept in circulating pumps. Pump performance and
characteristic curves are embedded in the memory of the
speed controller during manufacture. This data includes
power, speed, head and flow across the flow range of the
pump. During operation, the power and speed of the
pump are monitored, enabling the controller to establish
the hydraulic performance and position in the pumps
head-flow characteristic.
These measurements enable the pump to continuously
identify the head and flow at any point in time, giving
accurate pressure control without the need for external
feedback signals. Patented software technology within
the controller ensures trouble-free operation in all condi-
tions.
Incorporating the pump’s hydraulic data into the control-
ler and removing sensors results in true integration of all
components and removes the risk of sensor failure.
10.2 Set-up Menu
The controller has 4 different system set-ups:
