DESCRIPTION OF OPERATION
0740 800 144 - 29 - © ESAB AB 2018
The first version of the control board, 0486 205 886: When wire feed starts, the power source
generates welding voltage.
13AP1:13 Processor, Starting sequence, Motor type
Processor
The processor stores the machine program. It monitors the power supply voltages. If the
voltages drop to too low a level, wire feed is stopped, as described in section 13AP1:1
above.
The processor also monitors speed. If the wire speed deviates from the set value by more
than 1.5 m/min for more than 5 s, wire feed will be stopped.
Starting sequence, circuit board 0487 166 8xx
The circuit board displays the starting sequence from power-up.
1. LED1 lights red during 5 s. The software is in the boot mode.
2. LED1, LED2 and LED3 lights green. The software has started the application mode.
3. LED1 flashes continuously with a green light. The board is initiated, and the wire feed
unit is in the application program.
The starting sequence above applies to boards with software version 2.00A and later.
Boards with software version 0.27A have LED indication as described in paragraphs 2 and 3
above.
Boards with software version prior to 0.27A have no LED indication. The software version is
indicated by a label on the processor, IC1.

Motor type
The wire feeder mechanisms MEM 30 (for Feed 304) and MEL 48 (for Feed 484) need
different software for the motors. On the first version of the control board (0486 205 886) the
motor type is selected by the hardware. On the new versions the motor type is selected by
the software.
The new version of the control board, 0487 166 8xx:
When the board is tested, the software is set up for one of the motor types.
Feed 304 before serial no. 917-xxx-xxxx, motor with tachometer.
Feed 304 from serial no. 917-xxx-xxxx, motor with pulse generator.
Feed 484 all serial numbers, motor with tachometer.
