This
course has been designed
to familiarise Maintenance
Engineers with the many
different aspects associated
with the operation and
maintenance of GEM 80
programmable controllers.
Where
possible, application
specific exercises, actual
drawings and programs
listings are used to allow
the students to gain the
greatest possible benefit
from the course.
