The timer energizes the hopper solenoid; which opens the guillotine on the removable hopper, which allows coffee
beans to drop into the grinding chamber. The timer also energizes the capacitor which energizes the motor.
When the timer finishes its cycle, it removes voltage from the hopper solenoid, which closes the guillotine on the
removable hopper. The capacitor and the motor are on an adjustable delay (See Programming section). This delay
ensures that all beans have passed through the grind chamber, preventing cross contamination of different coffees.
After the delay, voltage is removed from the capacitor and the motor. The grind cycle timed sequence is complete.
The power/stop switch is used only when it is necessary to interrupt the grind cycle before the cycle is finished.
Grinder Foreign Object Protection
FETCO coffee grinders feature two types of overload protection to prevent damage to the unit if a foreign object
enters the grinding chamber and stalls the motor.
•
The control board is equipped with a thermal breaker with an audible alarm that will cut power to the motor
if the control board overheats.
•
The motor is equipped with a thermal breaker (no alarm) that will cut power to the motor if the motor
overheats.
Once the foreign object is removed and the unit cools down, the thermal breakers will automatically reset.
Warning: If this occurs D
O NOT TRY TO FIX THIS PROBLEM YOURSELF
. Immediately unplug the grinder and call a
qualified service technician.
Adjustments
Grind Adjustment
These adjustments are to be made by qualified service personnel only.
The grinder is factory set at medium grind.
If adjustment is necessary:
•
Remove all whole beans from hopper.
™ GR-1: Scoop out as many of the beans as possible.
Then lift the window straight up and sweep out the
remaining beans.
™ GR-2: Remove both hoppers and dump beans out, place both
hoppers back in grinder.
•
Select large portion switch and activate. This will clear grind chamber of all whole coffee beans.
•
Remove the front cover making sure to remove all four screws (2) in front (2) underneath next to coffee
outlet.
•
Using a 7/8” or 22 mm wrench turn retaining nut counter-clockwise at least one turn.
•
Using a 3/8” to 1/2” standard screwdriver turn the adjustment screw clockwise for a finer grind, counter-
clockwise for a coarser grind.
Note: Do not exceed more than a 1/4 turn in either direction.
•
Using a 7/8” or 22 mm wrench turn retaining nut clockwise locking adjustment screw in place.
•
Using a small amount of whole coffee beans test to make sure grind setting is correct if not repeat the
above steps.
Note: It may be necessary to adjust the timer cycle to compensate for the effect that the grind setting can make on quantity of coffee ground per
minute. A finer grind will produce less ground coffee per minute and a coarser ground will produce more ground coffee per minute.
To return grind setting to factory settings:
•
Follow the first four steps of the grind adjustment procedure.
•
Turn adjustment screw clockwise until burrs meet, back off slightly.
•
Using a marker, mark the twelve o’clock position of the adjustment screw.
•
Turn the adjustment screw counter clockwise to just past the four o’clock position.
•
Turn retaining nut clockwise locking adjustment screw in place.
•
Test by running small batch.
