Safety micro switch
Impeller Micro-switch - 1
This micro-switch is activated
by the impeller disc. The impeller
disc rises upward as coffee
is dosed into the portafilter.
When sufficient coffee has
been ground and dosed, the
impeller rises up far enough to
actuate the micro-switch, which
causes the grinder motor to stop.
Safety Micro-switch – 2
This switch is activated when
the portafilter is engaged in the
bayonet ring.
The grinder will not operate if this switch
is not activated.
Grinder Motor Reostat – 1 & 2
Adjusting this reostat
determines how long the
tamper motor runs after
the grinder motor has shut off.
If the tamper motor stops, the reostat
can be adjusted clockwise
to increase the polish time. The rheostat
determines the maximum amount of time
the grinder motor runs. If the grinder motor
stops before the portafilter is completely
dosed with coffee, the rheostat should be adjusted
clockwise to increase the grind shut-off time.
