11. OPERATING MODES DESCRIPTION
The pump can operate in 4 different operating modes.
Depending on the system in which the pump operates, the
pump can be set in the most appropriate mode.
Pump modes:
Each mode can coexist with the night mode
A
Automatic mode (factory setting)
In automatic mode, the pump automatically sets its operating
pressure according to the status of the hydraulic system.
By doing so, the pump automatically finds the optimal
operating position.
This mode is recommended in most systems. The parameters
cannot be set; they can only be scrolled through.
Proportional pressure
In this mode the pump continually
regulates the head based on the flow
rate, by varying the pressure in linear
fashion within the maximum to minimum
range. The value to be set (Hset on the
drawing) corresponds to the maximum
pressure at maximum power; at 0 flow
the pressure will be equivalent to 50% of the pressure
set (Hset/2). Between these two values, the pressure will
change linearly, in relation to the flow.
In this mode only the pump pressure can be set (Hset
on the drawing); the remaining parameters can only be
scrolled through.
Constant pressure
In this mode the pump maintains the
currently set pressure (Hset on the
drawing) constant, regardless from the
demand of the system (from 0 flow to
maximum power, at which point the
