Parameter "Aux. Con." = 2 – External enable and
alarm signal.
In this mode, an external electrical device (e.g. float,
timer, switch, etc.) can be connected between terminals 1
and 3, to enable remote operation of the pump. In this
mode the motor is only started up if the external contact
between terminals 1 and 3 is closed.
Terminals 5 and 6 provide a relay output that is
activated in the event of an alarm.
Jumpers must be wired onto terminals 2 and 4.
Parameter "Aux. Con." = 3 – External enable and
pump operation si gnal.
In this mode, an external electrical device (e.g. float,
timer, switch, etc.) can be connected between terminals 1
and 3, to enable remote operation of the pump. In this
mode the motor is only started up if the external contact
between terminals 1 and 3 is closed.
Terminals 5 and 6 provide a relay output that is
activated when the pump is runni ng; this signal
enables the control of external devices that have to
operated in conjunction with the electric pump (for
example a batching system for chlorine, fertilizer,
detergents etc.).
Jumpers must be wired onto terminals 2 and 4.
Parameter "Aux. Con." = 4 – Combi nation with
inverter device "Sirio"
When the parameter "Aux. Aus." is set to 4 Brio Top can
be interfaced with an inverter in the range Sirio or Sirio
Entry to produce a hybrid pressurisation unit, i.e. a
variable speed pump and a fixed speed pump that
intervenes as a backup to the main pump only in the
event of increased water demands by the system.
During routine operation, the system demands are
normally met by the pump with the Sirio inverter, which
is always started up first. When the demand for water
increases to such a point that the first pump is no longer
sufficient, the fixed speed pump, installed together with
Brio Top is then started up. Terminals 1 to 4 are used for
the connection of two devices while terminals 5 and 6
provide a relay output that is activated in the event of an alarm. The parameter "Aux. Con." can only be
set to "4" if the current operating mode is " P+P" (pressure+pressure).
CAUTION: incorrect connections of the auxili ary contact could cause i rreparable damage to
the device! Take great care when making the connection.
