Mode of Operation
Functionality - example
The diagram shows the level
control system connected as
max. and min control, i.e. reg-
istration of 2 levels + 2 alarm
levels. The relays react to the
low alternating current creat-
ed when the electrodes is in
contact with the liquid.
The reference (Ref) must be
connected to the container or
if the container are made of a
nonconductive material, to an
additional electrode. In the
diagram this electrode is
shown by the dotted line.
Electrodes
Cut or extend the electrodes
to the desirable length. If
using extended electrodes,
place the enclosed isolation
tube over the extension joint,
and heat it with a heat gun.
Mount the electrodes in the
probehead by means of the
M4 screw inserts. Take care
not to damage the isolation
m
aterial of the isolated elec-
trodes.
Connection cable
2, 3, 4 or 5 conductor PVC
cable, normally screened.
Cable length: max. 100 m.
The resistance between the
cores and the ground must
be at last 200k. In normal
cases it is recommended to
use screened cable between
probe and controller, e.g.
where the cable is placed in
parallel to the load cables
(mains). The screen has to be
connected to Y5 (reference).
