6.3 Connecting Sensors
6.3.1 Non Aseptic Port Sensor Attachment
NOTE: Sensor ports are specific to certain Allegro SUS designs. Check that the
sensor being used is compatible with the attachment method. Only use approved
sensors. The non-aseptic port is supplied with a plug that will provide a fluid seal
should a sensor not be required for the specific activity.
NOTE: Sensors must be installed in the Allegro single-use mixer system before fluid
is added.

14. Check all lights are on and the variable
s
peed drive is energized (shows ‘STOP’
o
n the display)
1. Turn the BAG INFLATION switch to the 'OFF' position.
2. Unscrew the plug from the non-aseptic sensor
port on the Allegro mixer biocontainer.
3. Insert appropriate sensor (e.g. conductivity) into the
sensor port and screw in to ‘hand tight’. Note: this
should be sufcient to create a uid seal during
operation (typically 0.5 Nm). If the port leaks, tighten
further. Contact Pall for recommended sensors.
4. Connect the sensor cable to the sensor to allow
display of the values (either locally on the mixer
via the optional sensor transmitter, or via a remote
system such as the Allegro MVP automated system).
