8.6. Factory reset

This parameter allows to reset the frequency
converter to factory settings.
WARNING: Before resetting the frequency
converter, make sure that the system is Off,
and that the pump/s are stopped.Once the
reset is done it's possible to configure the
previous settings only manually setting all
the modified parameters.
To reset the frequency converter it is necessary
change the value of the parameter AP50 from no to
yes, and push the button

9.1. Parameters to check when starting up the unit
Check that the motor voltage is matching or
i
it's lower than the Mains Supply voltage.
If the motor Voltage is different from 400V set the
parameter SA01 "Nominal Motor Voltage" in order
to match the value written in the motor label.
Once the frequency converter is turned on for the
first time, after a short check phase on the display
it's shown Er13.
If the entered rated current value is not
correct there is the risk of pump damage
or to have an unexpected overcurrent
alarmParameter
frequency
The nominal frequency of the pump must be set.
If the entered rated frequency value entered
is not correct there is the risk of higher
current absorption or pump damage.
If the selected programmed mode is different
from the purpose of the plant there is a risk
of pump damage and/or plant damage.
9.2. Constant pressure operating mode
Constant pressure operating mode keeps constant
the pressure at a point of the system.
In this operating mode the frequency converter
keeps constant the pressure at a set-point value
decided by the user through parameter UP06.
It is possible to have different configurations of this
operating mode related with the different types and
number of transducers installed:
- Constant pressure with 1 pressure transducer
(absolute or differential transducer)
- Constant pressure with 2 pressure transducers
in differential mode.
For detailed program settings see the following
configuration sections.
9.2.1. Constant pressure mode with single
transducer (absolute or differential)
This configuration uses a feedback given by a
pressure transducer (connected as shown in
section 6.7).
