The current operating data and operating conditions are shown on the LCD display and in-
dicated by LEDs. Operation and input of operating parameters is carried out using a rotary
knob.
The switchgear can operate in three different operating modes:
• Filling
When the liquid level in one or two tanks drops, the pumps are automatically switched
on individually and deactivated again when the level rises.
• Draining
When the liquid level in one or two wells rises, the pumps are automatically switched on
individually and deactivated again when the level falls.
• Pressure control
The pumps are switched on/off individually and automatically depending on the actual
pressure on the output side of the system.
