6.3 Additional installation instructions
Additional installation instructions which, from experience, reduce the effect of
electromagnetic interference:
Make line connections as short as possible
Use shielded lines (e.g. LIYCY 4 x 0.5 mm²)
The cable shielding must be fitted by qualified personnel, subject to the environmental
conditions and with the aim of suppressing interference.
Keep the instrument well away from the electrical supply lines of power equipment, as
well as from any electrical or electronic equipment causing interference.
Always
connect the
earthing screw
of the ENS 3000 to the earthing rail (e.g. in the
control cabinet). We recommend using a cable with a diameter of 1 mm² and as short a
line length as possible.
The level switch ENS 3000 should be mounted vertically inside the tank.
If not mounted vertically, the accuracy of the ENS 3000 may decrease with increasing tilt
angle
•
additional inaccuracy at a tilt angle of 5 °: approx. ±0.5 %
•
additional inaccuracy at a tilt angle of 10 °: approx. ±1.5 %
Caution
The ENS 3000 electronic level switch is not suitable for operation at pressures
exceeding atmospheric pressure. Short-time peak pressures up to 3 bar will not
cause damage to the device if not exceeding 1 minute of time.
