Maintenance and repair work must be performed by an experienced person, and electrical
work only by a trained electrician. Use only recommended replacement parts.
This service manual is intended for use by technicians with electrical/electronic training for
help in connection with fault-tracing and repair.
Use the wiring diagram as a form of index for the description of operation. The circuit boards
are divided into numbered blocks, which are described individually in more detail in the
description of operation. Component names in the wiring diagram are listed in the
component description.
Use the spare parts list as a guide to where the components are located in the equipment.
The spare parts list is published as a separate document, see the "SPARE PARTS" chapter
in this manual.
This manual contains details of design changes that have been made up to and including
February 2017.
The manual is valid for:
ESABFeed 30-4 M12, ESABFeed 30-4 M13, ESABFeed 48-4 M12 and ESABFeed 48-4 M13
with serial no. 238-xxx-xxxx, 410-xxx-xxxx, 440-xxx-xxxx, 502-xxx-xxxx
Feed 304 M12 and Feed 304 M13 with serial no. 620-xxx-xxxx, 917-xxx-xxxx, 623-xxx-xxxx
Feed 484 M12 and Feed 484 M13 with serial no. 620-xxx-xxxx
CAUTION!
Read and understand the instruction manual before
installing or operating.
The ESABFeed 30-4 M12, ESABFeed 30-4 M13, ESABFeed 48-4 M12, ESABFeed 48-4
M13, Feed 304 M12, Feed 304 M13, Feed 484 M12 and Feed 484 M13 are designed and
tested in accordance with international and European standards IEC/EN 60974. On
completion of service or repair work, it is the responsibility of the person(s)
performing the work to ensure that the product still complies with the requirements
of the above standard.
