20AP1 Control board
The processor on the control board monitors and controls the various functions of the power
source. It obtains information on welding data and welding processes from the welding data
unit.
Depending on the type of control panel, the power source control board is set up for combi
mode or power source mode.
In combi mode the board handles the control of the power source, the welding data unit and
the MMC panel.
In power source mode it handles the control of the power source. The MMC panel and
welding data unit are controlled by a board fitted in the MMC panel.
There are two hardware versions of the control board, for identification see page 34.
Spare part boards
There are three boards, one for power source mode and two for combi mode, one for each
control panel.
When replacing the board, do not forget to transfer the “terminal D jumper” and the “Y2-Y3
jumper” to the new board. See pages 30 and 32.
CAUTION!
This circuit board looks identical to the control board used in other power sources, but there
are differences both in hardware and software. If wrong board is used, it might cause
serious damage to the power source. Make sure that the replacement board has correct
article number, see the spare parts list.
Circuit board identity
Mig 3001i and Tig 3001i, power source unit
The control board has a machine ID, a hardware ID and a unit type number. To read them
you need the ESAT service kit, see page 45.
S The machine ID defines which type of power source the board is intended for.
S The hardware ID shows design and type of circuit board.
S The unit type is used for identification on the CAN bus.
The ID numbers of the power source units are:
Mig 3001i Tig 3001i
Machine ID = 46 from software version 1.06P,
see page 34.
Machine ID =45
Hard ware ID = 5 or 9 Hard ware ID = 5 or 9
Unit type = 2 Unit type = 2
Hardware ID 5 is used for version 1 of 20AP1
Hardware ID 9 is used for version 2 of 20AP1
Tig 3001i TA23 and Tig 3001i TA24, welding data unit and MMC
The ID numbers above refers to the power source control. The machine ID for the MMC part
of the board determines which type of control panel that is used.
The ID numbers of the MMC units are:
TA23 TA24
Machine ID = 21 Machine ID =20
Hard ware ID = 5 or 9 Hard ware ID = 5 or 9
Unit type = 0 Unit type = 0
Hardware ID 5 is used for version 1 of 20AP1
Hardware ID 9 is used for version 2 of 20AP1
