Advantage VFD Pump Controller Cards provide cutting-edge PID control for the Advantage 61,
E-Flex, and M-Flex variable speed drive lines. The card is capable of supporting both HVAC
and domestic water boosting applications.
For parallel or standby pumping applications, the Advantage VFD Pump Controller Card
will modulate, stage, and alternate up to four pumps. Only one controller card is required
to deliver all the functionality. Additional VFDs are connected (daisy chained) via standard
Ethernet (RJ45) and are automatically 'discovered' (plug and play) by the controller card.
Precision control is achieved by monitoring pressure, differential pressure, or central plant
differential temperature. The card receives a signal from the transmitter(s) or probes and
then modulates the VFDs according to internal algorithms and user defined setpoints.
Features and Benefits
- Multiple System Monitoring
Options - Controls variable speed
pumps based on three different user
selected metrics for variables including
building pressure, three independent
zones of differential pressure
(Delta P) or central plant supply
and return temperature (Delta T).
- Pump Staging and Duty Sharing
for Four Pumps - Monitors system
demands and stages pumps on and
off to satisfy demand and optimize
energy efficiency. Duty shares to
provide either equal run time or
skewed run time, delivering preferential
loading to owner designated
- Differential Pressure Control -
Monitors up to a three zone
differential pressure system using
three independent PID loops. The
Advantage VFD Pump Controller
Card determines the zone with the
highest demand based on a predetermined
setpoint for each zone.
It then regulates speed and staging/
destaging based on the requirements
of the most critical zone.
- Flow Reject Function -
Enhances system efficiency with the usage of
flow meters. By configuring the flow
value for a single pump system in
the Delta-P menu, the system will
de-stage all other pumps in operation
if the flow value drops below
the flow capabilities of a single
pump. This de-staging provision
operates in addition to the standard
de-stage function which may be
based on feedback error.
- Fault Tolerant Control - Ensures
that the system can still be satisfied
if signal loss occurs from any sensor.
The pumps immediately go to
a user defined default speed mode
(factory preset 45 Hz) and the controller
notifies the BMS that a fault
- Life Cycle Optimization - Improves
the pump life cycle by hydraulically
stable control, end of curve protection,
as well as energy optimization.
- Drive Parameterization (Auto-
Commissioning) - Reduces drive
setup time by transferring master
drive/motor parameters to other
VFDs in the system.
