Setup & Operation
Diagnostics Mode
The diagnostics mode is provided to allow the operator to check the input status of the
index sensor, the grinder motor thermostats and the start/stop buttons. From the mode
selection menu, press the #3 key or scroll to the Select Mode Diagnostics menu and
press the enter key. Scroll to the desired function and press the enter key or press the
corresponding number key. The control will timeout back to the mode selection menu
after one minute of inactivity. The three functions available in diagnostics mode are:
1. Index Sensor:
A proximity sensor located behind the index cam detects the position of
the cam to allow the control to count revolutions of the cam. Operate the index motor to
rotate the cam so it is positioned over the sensor. The sensor is equipped with a light that
should come on when it senses the cam. Enter diagnostic mode as described and select
the Index Sensor menu. The status should display as ON. Press the escape key to exit
the menu.
2. Grind T-Stat:
Under normal operating conditions, the status of the grinder motor thermo-
stats is ON. If the status is OFF, there is a problem with the motor or wiring and the
grinder motor will not run. Press the escape key to exit the menu.
3. Start/Stop:
The status is always OFF unless the corresponding button on the control is
pressed. Press the escape key to exit the menu.
