Switching functions
Level switch
The built-in relay can be pre-set to
either energise or de-energise when
the probe is in contact with the
liquid. Sensitivity must be adjusted
according to the conductivity of the
liquid.
Level control for filling
A minimum of 2 probe rods are required.
Set internal switch to "max"
(H). The relay energises when the
min. probe loses contact with the
liquid. The relay de-energises when
the liquid reaches the max. probe.
