VEGA VEGATOR 532 Ex - Manual (Page 23)

l Empty the vessel until the min. electrode is covered approx. 1 cm
by the product
l Turn the potentiometer slowly anticlockwise until the yellow signal
lamp extinguishes
The min. electrode is now adapted to the conductivity of the medium, i.
e. the relay deenergises at min. level and the transistor blocks.
Prerequirements
l First of all, connect only ground and max. electrode to the signal
conditioning instrument (terminals d28 and d30)
l Set the selection switch to mode A
l Connect the signal conditioning instrument to power supply
l Turn the potentiometer (channel 1) to position 0
l Fill the vessel until the max. electrode is covered approx. 1 cm by
the product
l Turn the potentiometer slowly clockwise until the yellow signal
lamp extinguishes
l Connect the min. electrode to terminal d32 of the signal
conditioning instrument
The two-point control is now adapted to the conductivity of the
medium, i.e. the relay deenergises at max. level and the transistor
blocks.
This switching condition remains until the level falls below the position
of the min. electrode, i.e. the relay energizes at min. level and the
transistor conducts.
The relay deenergises again at max. level and the transistor blocks.
Prerequirements
l First of all, connect only ground and max. electrode to the signal
conditioning instrument (terminals d28 and d30)
l Set the selection switch to mode B
l Connect the signal conditioning instrument to power supply
l Turn the potentiometer to position 10
l Fill the vessel until the max. electrode is covered approx. 1 cm by
the product
l Turn the potentiometer slowly clockwise until the yellow signal
lamp extinguishes
l Connect the min. electrode to terminal d32 of the signal
conditioning instrument
