6 Description and function

6.1 Description of the product (Fig. 1)

6.1.1 Function description

The Comfort control system, controlled by a pro-
grammable logic controller (PLC), is used to con-
trol and regulate pressure boosting systems with
up to 6 individual pumps. The pressure of a system
is controlled as a function of the load with appro-
priate signal transmitters. The controller acts on
a frequency converter (CC-FC design), which in
turn influences the speed of the base-load pump.
A modification of the speed changes the volume
flow and thus the power output of the pressure
boosting system.

2 devices in master/slave mode
Only the base-load pump is controlled by speed.
Non-regulated peak-load pumps are switched on
and off automatically according to load require-
ments, while the base-load pump handles fine-
tuning to the preset setpoint.
In the CCe version, each pump has an (integrated)
frequency converter.
