4. AUTOCHECK EXP SERVICE PROGRAM
5. The text Loading Language is shown in the
display. Now start Programming in Autocheck
EXP.
Programming blocked main circuit board
If the main circuit board is locked so that it cannot
communicate or be programmed in the usual way it
can be placed in a so-called boot mode. This should
only be used if the usual programming procedure does
not succeed.
1. Put the main switch in position 0.
2. Connect the USB cable and start Autocheck
EXP.
3. Lift and hold the mower by the front edge so
that the lift sensor is activated.
4. Put the main switch in position 1 (while at the
same time lifting the mower by the front edge).
5. Start Programming within 10 seconds.
Programming new main circuit board
If the main circuit board is replaced, the new main
circuit board must be programmed. The main
circuit board includes for instance information
about the robotic lawnmower's serial number. A
new main circuit board may for safety reasons be
only assigned one serial number which is never
changed. It is therefore very important that the
correct serial number is given.
There are three options when programming a
new main circuit board:
•
3020-015
•
•
3020-016
Select lawnmower from the log book.
This is the normal and safest choice.
Select the relevant robotic lawnmower
from the log book and the serial number
and operating data will be transferred
automatically to the new main circuit
board. This requires that the relevant
robotic lawnmower has once been
connected to Autocheck EXP.
Enter the serial number manually
If the relevant robotic lawnmower has
never been connected to Autocheck
EXP, the serial number has to be entered
manually. It is very important to enter the
correct serial number.
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
relevant robotic lawnmower, it is possible
to temporarily program the main circuit
board in a so-called Service Mode. In
Service Mode, a serial number is not
needed and the main circuit board is thus
not locked to just this robotic lawnmower.
In Service Mode most functions can be
tested and used as normal. However,
there is no access to the security menu
in the robotic lawnmower's display. It is
therefore very important never to return
the robotic lawnmower in Service Mode
to the customer. As long as the main
circuit board is in Service Mode, the
Service mode text flashes in the display.
