TECHNICAL OFFICE
The power board incorporates the electronics for programming the optimal operating settings
and storing the set parameters. The parameters are set by default directly in the factory.
However, it may be necessary to verify that these settings are correct or change some
parameters to adapt the machine to the user’s needs. To verify or modify the parameters,
with the exception of the technical settings that have a number between the letter and the
dot (example: U1.X, U2.X, y0.X, y1.X, y2.X, y3.X) and should not be modified, see the “User
Programming” and/or “Technical Programming” operating instructions.
When replacing the power board, it is always recommended to check the factory values and, if
necessary, modify the settings based on the user’s needs.

D1.3 Power board programming
The programming procedure is divided into two parts: a simpler part, for users, to set the brush
pressure in the two programs (however it is not recommended to modify these), and the filter
shaker activation times. There is then another more technical part: to change some essential
parameters, such as the type of battery installed or check current draw of the brush motor;
in this case too, it is not recommended to change the values of parameters indicated as non-
modifiable.

The display shows the information in a predefined order: at start-up, it first displays any
ERRORS, followed by the BATTERY VOLTAGE indicated with two whole numbers and one
decimal XX.X, then the TOTAL HOURS of machine operation, three whole numbers XXX, and
MINUTES with two decimals .XX. If the “Technical Display” function (UB.1) is enabled, the
CURRENT DRAWN BY THE BRUSHES, the HEAT SINK TEMPERATURE, the CURRENT SETTING
and the MAXIMUM HEAT SINK TEMPERATURE will be displayed flashing, following the
standard indications.
The possible errors shown on the display are C22 - problems with the brush MOSFETs, C14 -
heatsink MOSFET high temperature, FS0 - centre brush worn, SP1 - brush motor overcurrent,
and CP (cP) - communication error between the display board and the power board. For
troubleshooting, see the corresponding paragraph.
