Service instructions
In case of dubious measuring results please check all external connections carefully. It
is also good practice to check that the desired program has actually been stored in
EPROM. A TAG number can be stored for identification purposes (also see
section "Commissioning"). If there is no doubt about the fault lying with the device, it is
seldom possible to repair the unit on site. Local analysis should be restricted to a check
of the fuses.
Each fuse is tagged with its nominal value. Fuses must always be replaced by their
equivalents. Fuse positions may be taken from section "Technical data" figure device
layout.
Other faults require laboratory tests. Circuit diagrams can be made available at request.
Repairs can be carried out by our service department quickly and efficiently if units are
returned to the factory. Spares help to maintain production in such cases.
