The front of the switchgear comprises the following main components:
▪ Main switch for switching the switchgear on/off (not the “EMS” version)
▪ 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 individually switched on/off automatically, depending on the fill level.
Level measurement is via a two-position control for each pump. An optical signal as
well as a forced switch-off or switch-on of all pumps follows upon reaching the dry run
or high water level. Faults are stored in the fault memory.
The current operating data and operating states are shown on the LCD display and in-
dicated by LEDs. Operation and input of operating parameters is carried out using a
rotary knob.
4.3 Operating modes
The switchgear has two different operating modes:
▪ drain (drain)
▪ fill (fill)
Selection is via the menu.
“Drain” operating mode
The reservoir or pump chamber is drained. The connected pumps are activated when
the level rises and switched off when the level falls.
“Fill” operating mode
The reservoir is filled. The connected pumps are activated when the level falls and
switched off when the level rises.
