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

material 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).
