20Ap1 Control Board - ESAB Aristo Origo Arc 4001i Service Manual

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 is controlled by a board fitted in the MMC panel.
There are two hardware versions of the control board, for identification see page 31.
Spare part boards
There are two boards, one for power source mode and one for combi mode.
When replacing the board, do not forget to move the "terminal D jumper" and the "Y2-Y3
jumper" to the new board. See pages 27 and 29.
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
Arc 4001i and Mig 4001i, power source unit
The control board has a machine ID, a hardware ID and a unit type number. To read this
you need the ESAT service kit, see page 46.
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 Arc 4001i and Mig 4001i are:
Machine ID = 43
Hardware ID = 5 valid for version 1 of 20AP1.
Hardware ID = 9 valid for version 2 of 20AP1.
Unit type = 2
Arc 4001i A22, welding data unit and MMC
The ID numbers above refers to the power source control and are valid for power sources
both in combi mode and power source mode. For the Arc 4001i with MMC unit A22 there
are additional ID numbers:
S
The machine ID for the MMC part of the board determines which type of control panel
that is used. The machine ID can be changed by ESAT.
The ID numbers of the MMC unit are:
Machine ID = 38
Hardware ID = 5 valid for version 1 of 20AP1.
Hardware ID = 9 valid for version 2 of 20AP1.
Unit type = 0
