Imax:
this parameter enables entry of the maximum current absorbed by the electric pump in routine
conditions, to enable shut-down of the motor in the event of excessive absorption. The motor is also shut down
if the current read during operation is below 0.5 A following interruption of the connection between the motor
and
the inverter. The trip time of the current overload safety device is inversely proportional to the entity of the
overload in progress; therefore a slight overload will lead to a more delayed trip time while a more significant
overload will accelerate the trip time. On activation of the device, if the Imax parameter is set at 0.5 A (factory setting), the display
automatically shows the settings page of the maximum current and no action is permitted until the absorption limit value is set.
Rotation direction: this screen enables the user to invert the direction of rotation of the electric pump without
modification to the electric motor wiring. To modify the direction of rotation of the motor, use buttons "+" and
"-"; the direction indicated by the arrow has a purely indicative value and does not reflect the actual sense of
rotation which must be verified by the installer.
ADVANCED PARAMETERS:
The advanced parameters are accessible only to the technical assistance service. For access to these parameters, it is necessary to contact the
re-seller, a technical assistance centre or the manufacturer.
