The front of the switchgear comprises the following main components:
▪Main switch for switching the switchgear on/off
▪Operating button for menu selection and parameter input
▪LEDs for displaying the current operating state
▪LCD display for showing the current operating data and individual menu items
4.2 How it works
The pumps are switched on/off individually and automatically depending on the actual
pressure in the system. The pressure control for the Control EC-Booster is carried out
using a two-point controller. The pressure control for the Control ECe-Booster is car-
ried out using a PID controller. When the dry running level is reached, a visual signal is
displayed and a forced switch-off of all the pumps occurs. Faults are stored in the fault
memory.
The current operating data and operating conditions are shown on the LCD display and
indicated by LEDs. Operation and the input of operating parameters is carried out using
a rotary knob.
