Configuration - DGFLOW PRESFLO MULTI Manual Del Usuario

Configuration

Settable parameters:
- Running pressure.
When the pressure in the
system falls below the Pm,
PRESFLO starts-up the pump.
®
The Pm should always be
higher by at least 0.2 – 0.3
bar of the pressure genera-
ted by the column of water
overlooking PRESFLO .
®
The Pm value can be carried
in the field between 1 bar and
5 bar.
- Maximum current
allowed.
PRESFLO is fitted with a cur-
®
rent sensor, which continually
detects the absorption of the
pump. If the current remains
above the set Imax value for
a significant period of time,
PRESFLO stops the pump to
®
protect it from damages (LOCK
condition for OVERCURRENT).
PRESFLO nevertheless allows
®
the Imax to be exceeded for
short periods during the pump
start-up phase.
For correct functioning,
the Imax should be set at
a value higher by approx.
10 – 20% to the maximum
absorption of the pump
(normally indicated on the
rating plate of the motor).
If this rating value is not known,
it s better to leave the standard
Imax value (16A) to avoid that
the pump stops also in normal
absorption conditions.
The Imax value may be varied
in the field between 4A and
16A.
Disposal
When disposing of any
PRESFLO parts, adhere
®
to the relevant laws and
regulations in force in
the country in which the
equipment is being used.
Do not dispose of any
polluting parts in

Manufacturer's setting:
PRESFLO is supplied with the
®
following STANDARD CONFIGU-
RATION:
- Running pressure
Pm = 2 ( bar )
- Max. current allowed
I max = 16 ( A )
Configuration
The adjustment of the starting
pressure (Pm) and the ma-
ximum permissible current (I
max) is done by means of two
trimmers shown in FIG.
