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. The parameter is settable from 0.5 to 16 A by means of the keys
"+" and "-". To deactivate the current control protection of the motor, press the key "-" until the text
"OFF" appears on display. CAUTION: the factory setting is OFF and therefore a maximum current value
must be set to activate the protection.
Aux. Con. Descri ption
0 No function activated for auxiliary contacts
1 Enables communication between two Brio Top units within a twin booster set with
automatic alternation of pumps
2 Sets up the auxiliary contact for an external enable signal (e.g. float, timer, irrigation
controller) and enables the relay output (terminals 5 and 6 on the terminal board) for any
error signals. The relay contact closes in the event of an alarm.
3 Sets up the auxiliary conta ct for an external enable signal (e.g. float, timer, irrigation
controller) and enables the relay output (terminals 5 and 6 on the terminal board) for
pump operation signals. The relay contact closes while the pump is running.
4 Enables communication between a Brio Top unit and an inverter Sirio or Sirio Entry
within a twin booster set.
falls below Pmin. The secondary pump is shut down when the required flow falls below a limit set in this
parameter. The factory setting is 20 and the parameter can be set from 10 to 50. The setting of this
threshold depends on the type of pumps used, considering that a higher value of this parameter
corresponds to a quicker shutdown of the auxiliary pump, while a lower threshold value maintains the
auxiliary pump in operation even when the flow rate falls to low values.
Imax : this optional parameter enables entry of the maximum current
absorbed by the electric pump in routine conditions, to enable shutdown of
the motor in the event of excessive absorption. The motor is also shut down
event if the current read during operation is below 0.5 A following
interruption of the connection between the motor and Brio Top. The trip
Auxi liary Contact: this parameter enables the user to assign a specific
function to the auxiliary contacts available on Brio Top according to the
scheme below:
Limit pressure: this parameter defines a pressure threshold over which the
overpressure protection is activated. The fa ctory setting is OFF, to indicate
that the protection is disabled. To set a limit pressure, use keys "+" and "-".
To disable the function, press the "+" key until the text OFF is displayed.
Deactivati on threshold: when Brio Top is configured to operate in
conjunction with an inverter device Sirio (mode set to P+P and Aux. Con. set
to "4"), this parameter can be set to define the secondary pump deactivation
threshold. The secondary pump where the Brio Top is installed, is started up,
on request of the inverter controlling the primary pump, when the pressure
Alarm log "1" : in this screen the user can read the number of alarms that
have tripped due to activation of the dry-running protection (DR) and the
pressure overload device (OP). These data can be checked in the event of a
malfunction.
