14 VEGAKON 66
Pump control, mode A
• Fill the vessel until the shortest electrode is
immersed approx. 1 cm.
• Switch on the power supply.
• Set the A/B switch to mode A.
• Set the rotary switch to position "TEST min".
• Turn the rotary switch slowly clockwise until
the red LED lights.
• The instrument is adapted to the medium,
i.e. the relay deenergises at max. level. The
relay energises again only when the level
drops below the lowest point of the min.
electrode.
Example:
A filling pump is switched on when the min.
signal is reached, fills the vessel until the
max. signal is reached and is then
switched off.
Pump control, mode B
• Empty the vessel until the min. electrode is
immersed approx. 1 cm.
• Switch on the power supply.
• Set the A/B switch to mode B.
• Set the rotary switch to position "TEST
max".
• Turn the rotary switch slowly anticlockwise
until the red LED lights.
• The instrument is adapted to the medium,
i.e. the relay energises at max. level. The
relay deenergises when the level drops
below the min. electrode.
Example:
An emptying pump is switched on when the
max. signal is reached, empties the vessel
until the min. signal is reached and is then
switched off.
Setup
Dry adjustment
• With several identical measurement loop
(the same medium), the adjustment of one
instrument with the medium is sufficient, the
determined switch position can be trans-
ferred to all further instruments.
• If the conductance value is known, the
switching point adjustment can be carried
out acc. to the schedule "Rotary switch
position" (under "4.2 Switching point adjust-
ment").
• When exchanging the sensor electronics, it
is sufficient to carry over the settings from
the previous unit.
