1. General instrument description
By choosing the level switch you have acquired a quality
product which is outstanding for its high reliability.
The level can be shown in mm, inch or % on the large
4-position digital display.
The display is easily readable, thanks to the waterproof
housing which can be rotated. The selv-explanatory menu-dri-
ven parameter set-up is chieved with 3 keys. Unauthorised pa-
rameter changes can be prevented by means of a password.
Two programmable switching outputs, each independent of
the other, and a readily programmable analogue output are
available for connection with electrical controls. Each switching
output has two switching points with which the on and off
switching temperatures can be readily set (variable hysteresis).
The switching outputs are switched as opener or closer cor-
responding to the set switching points, hysteresis or window
functions, and indicated on the status display. An apparent
function error will be signalled on the digital display and can be
further processed in accordance with Desina. The electronics,
which are protected against reverse polarity, over-voltage and
short circuits are in a fully cast enclosure, and are thereby
resistant to moisture and vibrations.
2. Safety notes/ choice fo product
