TrueBlend™ Maintenance and Repair
Edition: February 2008 131
NOTE
Under a strong static charge the sensor can also be screwed 2-3 mm further
into the mixing chamber. This will wipe the material from the probe during
mixing.
Do not place the probe too close to the mixing blades. This may destroy it!

units built after September 2007.)

The level sensor switches when material passes in front of the active area. The
level sensor adjustment depends on the type of material and must be adjusted
accordingly.
1 Efector sensor should be installed into the rear of the blender chassis until
it just comes flush with inside of the rear of the mixing chamber. This
should be as close as possible to being flush and still allow access to push
button and indicator light (should be facing away from mixing motor – to-
wards outside of unit).
2 Once sensor is set into position install supplied nut on the back of sensor
until it tightens against the weld coupling on the back of chassis – tighten
to lock into place.
3 Once unit is powered make sure that all mixing components are in place in
chassis and close door.
4 Use a small screwdriver or pen and press the OUT OFF adjustment push
button until the yellow LED ring flashes at a rate of 1Hz – this should take
about 2 seconds. Release the OUT OFF button and the yellow LED ring
will turn off. The sensor is now set for the empty mixing chamber and
should need no further adjustement. IMPORTANT: Do not adjust the OUT
ON LED, this will switch the operation of the level sensor.
