Conditions for Installation
Before putting the system into
operation for the first time, make
sure there is no hazard of explosion
present at the place of installation.
If there is any indication that the
equipment does not function
properly (e.g., display remains blank,
or no display backlighting) due to
damage during transport, disconnect
the equipment from power and notify
your nearest Minebea Intec Service Center;
see also: "Safety Inspection" in
the chapter entitled "Care and Main-
tenance."
Take all equipment specifications
into account (see "Documents for
Hazardous Areas"). The explosion-
protected scale must be installed and
operated in accordance with
acknowledged rules of engineering.
Read
the chapter entitled "Warnings and
Safety Precautions" carefully and
observe all instructions.
Shock Resistance
Even though the EC1XS.-......-L scales
feature highly rugged construction,
there are some limits. Avoid exposing
the system to falling objects, side
impact, or shocks.
IP Rating
The display and control unit is
rated to IP65, and the stainless steel
weighing platform has IP68 protec-
tion. These ratings indicate the
following levels of protection:
First digit: rating 6 indicates that
the equipment is dust-tight; i.e.,
completely resistant to penetration
by solids. Second digit: rating 5 indi-
cates resistance to penetration
by water, including powerful jets of
water; rating 8 indicates resistance
to ingress of water during complete,
continuous submersion in water to
a depth of up to 10 meters (approx.
32 feet).
IP65 or IP68 protection is guaranteed
only if:
– the seals on the junction box are
installed correctly in accordance
with industry standards, and
– the connecting cables, protective
caps and cable glands were installed
and connected by a qualified
technician.
Notes on Integration into
Conveyor Systems
Any moving or rotating parts per-
manently attached to the
EC1XS.-......-L scale must be
designed so that they cannot affect
the weighing results.
For example, rotating mechanisms
must be properly balanced.
The EC1XS.-......-L must be clear on
all sides during weighing so that any
dirt or parts that fall will not create
a connection between the weighing
platform and any permanently
mounted preload components. Make
sure there are no cables or other
objects exerting force on the load
plate. Avoid generating static
electricity.
Conditioning the Weighing System
Moisture in the air can condense
on the surface of a cold weighing
instrument or other device whenever
it is moved to a substantially warmer
place. Condition the equipment for
about 2 hours at room temperature,
leaving it unplugged from AC power.
Afterwards, if you keep the equip-
ment connected to AC power,
the constant positive difference in
temperature between the inside of
the equipment and the outside will
practically rule out the effects of
moisture condensation.
