the machine. If the weight of ground coffee

was 6.5 grams, enter 0-0-6-5 using the

drink selection keypad. Empty the

2. Auger Calibration: This menu enables the engineer to calibrate the

auger settings (stored in the machines memory) to the type of coffee

dispensed and converts gram settings to run times (seconds). This

procedure must always be carried out by the engineer before the B2C

machine is used for the first time, when the type of coffee dispensed is

changed and before adjusting the water compensation.

Important! Before commencing the following procedure, ensure that you have

a set of accurate gram scales and a cup with which to catch the freshbrew

ingredient. Using the ‘tare’ function, calibrate the empty cup with the gram

scales. Ensure that the CoEx® brewer is removed from the machine, the

brewer waste bucket is in position, the freshbrew container contains ingredient

and the container outlet slide is open. To configure the Auger Calibration

proceed as follows:

1. From the Co-Ex Setup menu highlight Auger Calibration and press the ↵

(Edit) key to access the menu screen as shown. The procedure is the same

as for Grinder Calibration (see page 42), follow the on screen instructions

weighing the dispensed freshbrew ingredient and entering the weight.
