8.6. 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 confi gure the
previous settings only manually setting all
the modifi ed parameters.
To reset the frequency converter it is necessary
change the value of the parameter AP50 from no to
yes, and push the button
During this phase the display is turned off for
few seconds, then it will turn off, and it becomes
possible to reprogram the frequency converter.

9. Operating mode programming

9.1. Parameters to check when starting up the unit
Once the frequency converter is turned on for
the fi rst time, after a short check phase on the
display it's shown Er06, this means which some
parameters common to all the operating modes
need to be set:

Parameter UP02 Nominal pump current.
The nominal current of the pump must be set.
If the value is inappropriate there is the risk
of pump damage or to have an unexpected
overcurrent alarmParameter UP03 Nominal
pump frequency
The nominal frequency of the pump must be set.
If the value input is inappropriate there is the
risk of higher current absorption or pump
damage.Parameter UP05 operating modes
Operating modes must be set.
PC Constant pressure mode
PP Proportional pressure mode
Ct Constant temperature mode
CF Constant fl ow mode
MAn Fixed speed mode
If the operating 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. To enable this
operating mode it is necessary set the parameter
UP05 on "PC". 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 confi gurations 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
confi guration sections.
9.2.1. Constant pressure mode with single
transducer (absolute or differential)
This confi guration uses a feedback given by a
pressure transducer (connected as shown in
section 6.7). To allow this transducer properly work
it is necessary to set parameter AP02 (to defi ne
the supply of the transducer), parameter AP03 to
1 (bar) and the parameters AP03 and AP05 to the
right transducer full-scale (refer to the datasheet of
the transducer).
