26 VEGACAP
Setup
Vertically mounted electrodes
( with oscillator CAP E30… , fig. 4.1
)
(VEGACAP 11, 21, 31, 33, 34, 42, 52, 53, 60,
61)
Mode A
(Max. detection)
• Make sure that the test switch (outside on
the housing - option) is set to position 0.
• Set the A/B-switch (4) to mode A.
• Set the changeover switch (6) to position 1.
• Fill the vessel to the requested level.
• Turn the potentiometer (5) to 10; the control
lamp (2) extinguishes.
• Turn the potentiometer (5) very slowly
anticlockwise until the control lamp (2)
lights. If the control lamp does not light, set
the changeover switch (6) to the next
higher stage and repeat the adjustment
with the potentiometer until the control lamp
lights. The measuring system is ready for
operation.
Mode B
(Min. detection)
• Make sure that the test switch (outside on
the housing - option) is set to position 0.
• Set the A/B-switch (4) to mode B.
• Set the changeover switch (6) to position 1.
• Lower the product down to the requested
min. level.
• Turn the potentiometer (5) to 0; the control
lamp (2) extinguishes.
• Turn the potentiometer very slowly clock-
wise until the control lamp (2) lights. If the
control lamp does not light, set the
changeover switch (6) to the next higher
stage and repeat the adjustment with the
potentiometer until the control lamp lights.
The measuring system is ready for opera-
tion.
Adjustment-free electrodes for adhe-
sive products
( with oscillator CAP E31 R , fig. 4.2)
In general, the measuring probes VEGACAP
27, 35 and 98 (up to max. 3 m) in conjunction
with oscillator CAP E31 R no longer require
adjustment (see exceptions on the following
pages). The vessel must not be filled for the
adjustment.
With the A/B-switch (4) you can choose the
mode of VEGACAP, whether the level switch
should be used as max. detection A (overfill
protection) or as min. detection B (protection
against dry running of pumps).
These measuring probes have an active
length and a screening segment. Due to this
screening segment, the standing capaci-
tance caused by the vessel after the installa-
tion of the electrode is almost completely
compensated.
