VEGA VEGATOR 521, 522, 523, 527 - Manual (Page 12)

12 VEGATOR
DIL switch block
One DIL switch block (14 and 15) per output
with 6 switches each is located on the circuit
board of VEGATOR. The individual switches
are assigned as follows:
1 A/B mode
A - max. detection (overfill protection)
B - min. detection (dry run protection)
2 Switch off delay (za)
3 Switch on delay (ze)
4 Integration time 2 s
5 Integration time 6 s
6 Integration time 12 s
You can set the mode (A - overfill protection,
B - dry run protection) with switch 1. When
used as part of a certified overfill protection
system, switch 1 must be set to A.
With switches 2 and 3, the switch on and/or
off delay can be adjusted independently. The
switch on or off delay relates to the switching
conditions of the relay and transistor outputs.
As example in the following illustration, mode
A (max. detection or overfill protection) is
selected (switch 1). The switch on delay is
activated (switch 3) and the integration time
is set to 8 seconds (switch 4, 5 and 6).
1 A/B mode
2 Switch off delay
3 Switch on delay
4 Integration time +2 s
5 Integration time +6 s
6 Integration time +12 s
Setup
Potentiometer
The switching point of VEGATOR or the
hysteresis (VEGATOR 522) can be changed
via potentiometer (3 and 6). For
potentiometer setting, use a small
screwdriver.
Signal lamps
LEDs in the front plate indicate, operation,
switching conditions and failures.
Green
- operation control lamp (9)
- mains voltage on, instrument in operation.
Red
- failure lamp (5 und 8)
- failure on the respective sensor current
circuit by sensor failure or cable breakage.
- if the fail-safe relay is deenergised, the red
signal lamp lights.
Yellow
- relay control lamp (4 and 7)
- the yellow control lamp reacts according to
the adjusted mode (A/B).
- in general, the relay control lamp signals
the activated (energised) condition of the
relay.
- a dark signal lamp means that the relay is
deenergised.
Min./Max. switch
(only on VEGATOR 527)
The min./max. switch (12) is used for
connection of both sensor inputs to one
common min./max. signal.
