Repair and maintenance
– Repairs are subject to checking
and can be carried out only at
Denver. In case of defect or func-
tional trouble, please contact your
local Denver dealer for repair.
When returning the instrument for
repair, an exact and complete fault
description must be supplied.
Only a trained technician aware
of the hazards involved may carry
out maintenance work, during
which the relevant precautions
must be taken.
Important note:
– Make sure that the construction
of the instrument is not altered to
the detriment of safety.
In particular, leakage paths, air
gaps (of live parts) and insulating
layers must not be reduced. The
manufacturer cannot be held
responsible for personal injury or
damage caused by an instrument
repaired incorrectly by user or
installer.
– Only authorized service techni-
cians who have been trained by
Denver and who follow Denver’s
standard operating procedures for
maintenance and repair may open
the scale. If you see any indication
that the scale cannot be operated
safely (for example, because of
equipment damage), turn off the
scale and lock it in
a secure place so that it cannot be
used for the time being.
– If you use suction lifting equip-
ment to lift the load plate, always
wear gloves, hard-toed safety
boots and protective clothing.
Warning: This procedure can
cause personal injury! Only
reliable personnel who are quali-
fied to perform such work are
allowed to use suction lifting
equipment.
– Always make sure the scale
is disconnected from AC power
before performing any installation,
cleaning, maintenance or repair
work.
– Check the pin assignment if
you use cables purchased from
a different manufacturer. Before
connecting such a cable to Denver
equipment, check the pin assign-
ment on the corresponding wiring
diagram or chart and disconnect
any wires that are assigned
differently from those specified
by Denver. The operator shall be
solely responsible for any damage
or injuries that may occur when
using cables not supplied by
Denver.
