VEGA VEGATOR 521, 522, 523, 527 - Manual (Page 19)

VEGATOR 19
Setup
Turn the potentiometer (3) very slowly
clockwise until the relay control lamp (4)
lights (mode A) or extinguishes (mode B).
Note the value adjusted now.
Set the potentiometer (3) to the average
value of the two noted values.
Channel 2
Carry out the adjustment like for channel 1.
Then repeat the adjustment with the
adjustment elements for channel 2.
If necessary, choose the following
adjustments on the DIL switch blocks (14
and 15):
- switch off delay, switch on delay
- integration time (0.2 … 20 s)
VEGATOR is now ready for operation.
VEGATOR 527
Double point control with 2 sensors
For switch point adjustment also note "4.1
Indicating and adjustment elements" (the
numbers in brackets refer to the illustration).
Horizontally mounted meas. probes or
meas. probes for very adhesive products
Here, signals of two measuring probes, e.g.
mounted to min. or max. levels, can be linked
to one common pump control signal.
Choose on the DIL switch blocks (14 and 15)
the mode (A - overfill protection, B - dry run
protection). Make sure that switch 1 of the
two DIL switch blocks (14 and 15) is
adjusted to the same mode (both the mode A
or both the mode B)
Set the min./max. changeover switch (12) to
off.
After having selected mode A, make sure
that the meas. probe of channel 1 is always
mounted in a higher position than the meas.
probe for channel 2.
In mode B, the meas. probe of channel 1
must be mounted lower than the meas. probe
of channel 2.
Make sure that the integration time is
switched off. The switches 2 - 6 of the DIL
switch blocks (14 and 15) must be in Off
position. Set the potentiometer (3) to 0.
Channel 1
Lower the level at least 100 mm below the
measuring probe 1.
Turn the potentiometer (3) very slowly
clockwise until the relay control lamp (4)
lights (mode A) or extinguishes (mode B).
Note the adjusted value now.
Fill the vessel until the measuring probe is
covered completely. With measuring probes
for very adhesive products, the sensitive tip
(standard 100 mm) must be covered
completely.
Turn the potentiometer (3) very slowly
clockwise until the relay control lamp (4)
lights (mode A) or extinguishes (mode B).
Note the adjusted value now.
Set the potentiometer (3) to the average
