WTX110
- Keep to the rated voltages of the connecting cable.
- Double-shielded cable is advantageous (braided shield)
- The length and cross-section of the individual wires must meet the
following conditions:
Cable length (m) / cross-section (mm
@
)
v
270 (m/mm
@
)
- Maximum line length between load cells and weighing terminal: 200 m
S
The shield of the load cell cable must be fitted across a large area all-round
in the screwed cable gland of the weighing terminal. This can be done with
all WTX110 variants. An additional connection for potential equalization is
located on the bottom of the WTX110.
S
The load cells and load receptors, terminal boxes and weighing terminal
must be integrated into the equipotential bonding system. To do this,
depending on the local conditions, it may be necessary to lay a separate
equipotential bonding line with a corresponding cross-section (e.g. 16mm
@
).
S
Use only metal terminal boxes to extend cables, and fit the shielding for
both cables in the screwed cable glands.
S
Cable laid a minimum of 50 cm away from power lines. Lay cable in
grounded steel conduit, metal tubing or metal cable ducts.
S
When load cells are under tension rather than compressive load, the +
and – signal connections must be swapped.
4.5.2 Saving calibration data for legal for trade applications
The calibration data can be saved on the ADM motherboard with jumper W1.
In the factory settings W1 is always set to calibration enabled!
