The plate electrode is fitted with two separate electrodes in the form of two electrode plates: 
1 control electrode and 1 earth electrode. As soon as a trace of a conductive liquid creates 
a conductive path between the two electrode plates, a control current flows from the 
corresponding electrode relay. The latter is then energised and a contact made.

The PE-Z10 or PEK-Z10 plate electrode or the plate electrodes combination PE + PE-Z10 or 
PE + PEK-Z10 may only be connected to the Leckstar 101 electrode relay. The connection 
must be made in line with the circuit diagrams.

Max. length of connecting cable between plate electrode and electrode relay: 1,000 m.
