11. Parameters to check when
starting up the unit
There are 4 programming parameters that need
to be checked when the unit is started up:
• Parameter UP02 NOMINAL PUMP CURRENT
The nominal current of the pump must be set.
If the value input is inappropriate there is
the risk of pump damage or to have an
unexpected overcurrent alarm.
• Parameter
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 SET POINT PRESSURE
The working pressure of the pump must be set.
If the value input is inappropriate for the needs
of the system, the value can be increased or
decreased using the
(plus) or
(minus)
keys.
If during the first start-up of the unit, filling
the system takes longer than 1 minute and
the unit signals a dry-running alarm,
Increase the parameter AP06, until the
pressure rises above the set value and the
pump remain on. (Make sure the pump
are primed).
11.1. Vessel pressure
Once the new working pressure is entered,
the tank pre-loaded pressure must be
changed to be 2/3 of the working pressure
(i.e. 4 bar working pressure,tanks to be
pre-loaded at 2.7 bar).
