Test Switches
Press any of the input buttons on the membrane switch, the display will show which button is being pressed.
Test Servers
Insert or remove a server from each side of the brewer. The brewer indicates if the server is removed or in place
based on the transformer load.
Test Frequency
The funnel sensing circuit is tuned to 125 kHz. If the circuit is not tuned correctly, then the funnel information will not
be transferred to the brewer. Therefore, the microprocessor is constantly
fi
ne tuning to get as close as possible to
125 kHz. It has eight possible tuning steps numbered 0 - 7. When you look at the “TEST FREQUENCY” screen you
see something like (124.7 KHZ .5) The 124.7 is the frequency, and the 5 is the tuning step. The decimal point next to
the 5 indicates the funnel is being detected; if the funnel is removed the decimal point should turn off.
Service Fault Messages

show up on the display.

fl
ow is full. The unit may be over

lling or boiling.
