– 19 –
CONTROL BOARD POWER UP
Each time power is applied to the control board, the bootloader is launched. The bootloader looks at the
ash conguration to choose which of the three conguration modes to use.
During the boot up process, the conguration mode number 1, 2, or 3 is displayed in the HUMIDITY display
for several seconds.
This function is used to help the technicians verify the proofer control board is congured correctly.
