setting value
01 Language
02 Motor rated current (Amp) 8,0
03 PF alarm 0,50
04 Time 1st restart (minute) 10
05 Time 2nd restart (minute) 20
06 Time 3rd restart (minute) 40
07 Time 4th restart (minute) 80
08 Air alarm time (second) 5
09 Minimum voltage alarm (Volt) 360
10 Maximum voltage alarm (Volt) 440
11 Audible alarm no water (yes - no) yes
12 Parameters protection (yes - no) no
01 Language:
Used to select the message language. Italian,
English, French and Spanish are available.
02 Motor rated current:
(from 1 to 18A). The motor rated current value
must be input in Amps.
03 PF (Power Factor) alarm:
(from 0.20 to 0.95. Factor setting 0.50).
Normally this value is valid for all motors. For a
better setting, start the pump and read the PF
value, set it at 20% less.
04 Time 1st restart: (see note 1)
All the times go from 0 (exclude attempt) to a
maximum of 250 minutes. The time in minutes
is input in this parameter between when the
pump stops due to lack of water and the first
restart.
05 Time 2nd restart: (see note 1)
Input the time in minutes in this parameter
between the second time the pump stops due
to lack of water and the second restart.
06 Time 3rd restart: (see note 1)
Input the time in minutes in this parameter
between the third time the pump stops due to
lack of water and the third restart.
07 Time 4th restart: (see note 1)
Input the time in minutes in this parameter
between the fourth time the pump stops due to
lack of water and the fourth restart.
08 Air alarm time:
A time must be input between 0 (exclude
alarm) and 12 seconds.
When the pump working time is greater than
the set time, the function is considered normal.
When the pump working time reduces and
becomes less than the set time (due to a
reduced air cushion in the tank), after three
starts the control unit stops the pump due to
lack of air cushion in the tank and sends the
message NO AIR IN THE TANK ( patented
system). Install a tank of sufficient capacity to
prevent the pump performing an excessive
starts number. Remember that the 4” (100 mm
diameter) submerged pumps are dimensioned
for around 20 starts per hour.
09 Minimum voltage alarm: (see note 2)
(from 340 to 390V). The minimum power
voltage must be input, below which the pump is
stopped.
10 Maximum voltage alarm: (see note 2)
(from 410 to 460V). The maximum power
voltage must be input, above which the pump is
stopped.
11 Audible alarm no alarm:
Select YES to activate the alarm if there is no
water; if NO is selected the alarm is not
activated. If YES is selected, the alarm is
activated when the low PF guard triggers, and
remains activated when the time is being
counted before restarting.
12 Parameters protection:
By selecting YES, all the data entered into the
programming parameters are displayed. To
modify them, enter again into programming by
pushing PROG button. The word PASSWORD
_ _ _ _ _ _ is displayed. Press the 6 buttons of
the PASSWORD in the right sequence
(),
select the desired parameter and change the
data previously set. By selecting NO (Factory
setting value) it is possible to enter and exit
from the programming parameters and freely
change the set values.
