BASE SETUP
1.1. ADVANCED CONFIGURATION (ADVANCED SETUP)
The ADVANCED SETUP menu groups together the parameters which allow optimising operation in
particular plant engineering situations. The setting of certain parameters requires precise plant
engineering skill and wrong configuration could worsen control behaviour.

2.1 RESTART DIFF DPr Restarting differential pressure bar 0.4 0.1 1.0 0.1
The DPr value determines the pump restart pressure given a certain set pressure P1
example:
PRESSURE SET 1 (P1) = 3,0 bar
RESTART DIFF ( DPr) = 0,2 bar
Re-starting pressure = 3,0 - 0,2 = 2,8
The pump will start when the plant pressure drops below 2.8 bar.

2.4 MAX FREQ HiF maximum operating frequency Hz 50 40 70 1
The parameter limits the maximum operating frequency of the pump controlled by the inverter; the
maximum frequency must normally coincide with the plate frequency of the motor pump (50 or 60
Hz), but the possibility exists of this varying down or up by +/- 10 Hz, with 1 Hz step.
IMPORTANT: the choice of exceeding the maximum frequency is the responsibility of the installer,
who must realise the consequences of raising the maximum frequency on the risks related to the
motor, to the pump and to the electrical system.
