NOTICE
The configuration of the hydraulics must be carried out before establishing the twin-head
pump connection. With twin-head pumps delivered from the factory, the hydraulic position
is pre-configured.
10.3 Display for twin-head pump operation
Two pump symbols are displayed in twin-head pump operation in the "Active influences" area. This is what
they mean:
• The left symbol represents the pump being viewed.
• The right-hand symbol represents the partner pump.
The indication of the symbols in the display differs for generic twin-head pump and two-pump system in-
stalled with two single pumps in the Y-piece:
Generic twin-head pump
On the twin-head pump, the left drive is equipped with a graphic display and the right drive with an LED dis-
play.
The graphic display of the main pump shows the values and settings.
On the graphic display, the home screen is visible as with a single pump.
Nothing is shown on the LED display of the partner pump.

play showing values and settings.

tion, correspond 1:1 to the values of the active drive.
