2.1 Address RFID modules

The number of LED flashes indicates the currently selected address number.

RFID modules enable contactless identification of parts of a coffee machine or system. For this, the RFID
modules must be correctly addressed - this is already done during production. Manual addressing is
therefore only necessary in the case of defective RFID modules.

Currently, RFID modules are used for SB1200 and A300. However, the latter contains only a single copy.
Since each replacement RFID module is factory-programmed for address 1, the A300 does not require
manual addressing in the event of an RFID defect.

1 Switch for RFID addressing 2 LED

ü The SB1200 is connected to the power grid.
ü The affected assembly or appliance is disconnected from the power grid.

1. Connect the affected assembly or appliance to the power grid and simultaneously hold down the
switch [1].

ð The switch produces a clicking sound.
ð The RFID module starts the addressing mode.
ð The LED [2] flashes once every 5 s.

2. Briefly press the switch [1] for a higher address number (max. 1 s) or press and hold (2 s) for a lower ad­dress number.

ð The address number increases or decreases by the value 1.
ð The LED [2] generates a flashing signal every 5 s corresponding to the currently selected address

number.

3. Press switch [1] briefly or hold it until the desired address number is reached.

4. Disconnect the affected assembly or appliance from the power grid.

ð The RFID module exits the addressing mode.

5. Connect the affected assembly or appliance to the power grid.

6. Perform all work steps for the remaining RFID modules.
