5.4.3 Programming a new main circuit board
If the main circuit board is replaced, the new main circuit
board must be programmed. The main circuit board
includes information about the product's serial number.
Note: A new main circuit board may for safety reasons
only be assigned one serial number which is never
changed. It is therefore very important that the new main
board gets the correct serial number.
There are 3 options when programming a new main
circuit board:
• Select product from the Log book
Select product from the Log book and the serial
number and operating data is transferred
automatically to the new main circuit board. This
requires that the product previously has been
connected to Autocheck.
• Enter the serial number manually in Autocheck
If the product never was connected to Autocheck,
the serial number must be entered manually in the
Actions - Unit replacement menu. It is then very
important to enter the correct serial number.
• Use Service mode
If the main circuit board is replaced when
troubleshooting, and you are not sure if the main
circuit board will be kept in the product, it is possible
to temporarily skip to enter the serial number and
use the main circuit board in a so-called
mode . As long as the product is in the Service
mode , the Service mode text flashes in the display.
WARNING: Do not return the product to the
customer in
