9.6.1 Calibrate/adjust a sensor with no material present.
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.
Instructions:
Î
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 – towards out-
side of unit).
Î
Once sensor is set into position install supplied nut on the back of sensor un-
til it tightens against the weld coupling on the back of chassis – tighten to lock
into place.
Î
Once unit is powered make sure that all mixing components are in place in
chassis and close door.
Use small screwdriver or pen and press the adjustment push button until the
green LED flashes at one Hz or 1 flash per second (a maximum of 5 seconds).
Release the button as soon as the flashing starts, and after a short time, the
green LED lights solid. This means the unit is set and is in operating mode. Unit
is set and should need no further adjustment.
IMPORTANT
Do not hold longer than 5 seconds.
Holding 10 seconds locks the sensor.
Î
Once unit is installed hold a finger over the sensing part of the sensor and
make sure that the LED changes state from green to red – this indicates that
the unit is working properly.
