Control lamps
LEDs in the front plate indicate the operating
status, switching condition and faults.
Green
- operating control lamp (9)
- mains voltage On, instrument in operation.
Red
- signal lamps (5 and 8)
- failure of the respective sensor circuit
through sensor failure or line defect.
- when the fail safe relay deenergises, the
red control lamp lights.
Yellow
- relay control lamp (4 and 7)
- the yellow control lamps react according to
the adjusted mode (A/B).
- the relay control lamps indicate the ener-
gised condition of the relay.
- an unlit control lamp thus means that the
relay is deenergised.
DIL switch block and potentiometer
Mode and integration time
On every output of the circuit board of
VEGATOR there is one DIL switch block (13
and 14) with 6 switches each. The individual
switches are assigned as follows:
1 A/B mode
A - max. detection or overfill protection
B - min. detection or 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
With switch 1, the mode (A - overfill protection
or B - dry run protection) can be adjusted.
When used as part of a certified overfill pro-
tection system, switch 1 must be set to posi-
tion A.
With switches 2 and 3 you can adjust inde-
pendently the switch off and/or the switch on
delay. The switch on or off delay relates to the
switching status of the relay and transistor
outputs.
In the illustrated example, 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
With switches 4, 5 and 6 the integration time
can be adjusted respectively. The time inter-
vals of the activated time switches are
summed. In case the switch on (ze) and
switch off delay (za) are activated together,
the adjusted time is valid for both types of
delay.
