La Marzocco FB-80S Installation Manual

La Marzocco Technical Bulletin #46

New GB/5, FB/80 and GS/3 FIRMWARES

Dear La Marzocco Family Member,

Herewith we would like to inform you about the latest firmware modifications on our machines.

After machine SN 3262, on ALL GB5 AV & FB80 AV we are installing new standard firmware.

The actual version is v.1.30.

The only difference with the previous version is the delay of the FLOWMETER ALARM, which formerly was
appearing after 5 seconds from the flowmeter error and is now appearing after 15 seconds from the
flowmeter error.

This modification will make the ALARM go on strictly in case of actual flowmeter malfunction.

Furthermore, after machine GS1106 (produced in June 2010), ALL GS/3 models have new firmware v.1.05
(MP) and v.1.15 (AV), which improves the control of the CPU on heating elements.

We remind you that all firmware can be installed through a SOFTWARE UPDATE USB KIT (# E.4.025) that
can interface any personal computer with the machine’s CPU.

Please do not hesitate to contact me if you need further clarification.

Sincerely yours,

Enrico Wurm
