Features
Description
A1
Current monitoring Pump is turned off instantaneously if this
value exceeds a peak that can damage the
electronic components
- high starting current
- short-circuit on motor.
A2
Surge protection
Pump is turned off if the voltage exceeds a
maximum instantaneous limit (+15%Vn)
A3
Undervoltage
Pump is turned off if the voltage falls under
15%Vn.
A4
Temperature
protection
If the temperature of the pump controller
exceeds 85°C the integrated temperature
protection is activated and power reduced.
The motor will run at 90% of the value
imposed (F2)
A5
Current overload
protection
The current overload is limited over a period
of time (defined by I2t algorithm) to protect
the motor insulation (for correct functioning,
the rated current must be set (F2)).
A6
Pressure switch
malfunction
In case of a problem or failure of the pressure
switch, the controller turns off the pump. A
restart must follow manually (press STOP
followed by START).
A7
Minimum
Flow
Flow rate
monitoring
This monitoring stops the pump if all the
fixtures are closed and the flow rate returns
to zero (normal operation).
A8
Dry
Working
Dry running
If no water is supplied, the red LED will blink
and stop the pump after 40 seconds. After 5
trials of automatic restart without success,
the pump will permanently stop and the
ALARM LED will light up.
All alarms messages are displayed on the segmented LED indicator. The alarm indicator blinks if
the alarm message is accompanied by an automatic restart (i.e. Dry running). The alarm indicator
does not blink if, for protection, a manual restart is necessary (press STOP, then START).
