24 V DC POWER
Used for supplying power to the weighing platform version of the Allegro 50 L Mixer.
MOTOR COMMS
Used to link the Allegro 50 L mixer to the Pall Allegro MVP automated system to enable control
of the mixer remotely from the Allegro MVP system (either manually or as part of a defined
automated phase programed in the Allegro MVP system Phase Step Configurator).

Mixer remote operation: The mixer impeller can be controlled remotely by connecting it to the
Pall automated Allegro MVP systems via the ‘motor comms’ port (see Figure 6). When the
blanking plug fitted to this port is removed, the UCI for remote operation is enabled.
NOTE:
Local operation of the mixer is not possible if the motor comms plug is removed.
NOTE:
If the remote control cable is removed, the motor comms plug must be re-connected
to the UCI to enable local operation of the mixer from the UCI keypad.
The ‘Stop’ button will always stop the impeller regardless of system settings.
• Fitting the remote cable into this port and connecting the other end to the Allegro MVP system
allows the impeller to be started and stopped, the speed adjusted and the motor direction to
be reversed remotely. For further information on how to operate these functions please refer to
the instructions for use of the Allegro MVP system.
• Note: If the remote control cable is removed, the port plug must be re-attached to enable
normal operation from the UCI keypad.
5.2 Connections to the Allegro Jacketed 50 L Mixer
Connecting and disconnecting the recirculation loop from the Allegro jacketed mixer tote
1. Ensure the mixer tote is on level floor and the wheels are locked.
2. Initially set up the thermal circuit, which includes the thermal control unit/utilities supply unit
and recirculation loop for the heat transfer fluid. Connect this thermal circuit to the inlet and
outlet nozzles of the Allegro jacketed mixer tote.
3. After the tote is connected to the thermal circuit via the inlet and outlet nozzles, the heat
transfer fluid is filled in the heat exchanger and circulated through the jacket. Either site utilities
or a thermal control unit can be used to establish the flow in the thermal circuit. The differen-
tial pressure between the inlet and outlet shall be used to establish the desired flow rate for
the thermal transfer fluid.
