VEGATOR 536 Ex 11
Signal lamps
LEDs in the front plate show operation,
switching condition and failures.
Green
- Operating control lamp (6)
- Mains voltage on, instrument in operation.
Red
- Failure lamp (5)
- Failure on the individual sensor current
circuit by sensor failure or line defect.
- When the fail safe relay is denergised, the
red signal lamp lights.
Yellow
- Relay control lamp (4)
- The yellow signal lamp reacts depending
on the adjusted mode (A/B).
- The relay control lamps indicate the acti-
vated (energised) condition of the relay.
- A dark relay control lamp means that the
relay is in denergised condition.
DIL-switch block and potentiometer
Mode and integration time
A DIL-switch block with 6 switches (9) is
located on the circuit board of VEGATOR.
The individual switches are cordinated as
follows:
1 A/B-switch
A - max. detection or overfill protection
B - min. detection or dry run protection
2 Switch off delay
3 Switch on delay
4 Integration time 2 s
5 Integration time 6 s
6 Integration time 12 s
The mode can be adjusted (A - overfill pro-
tection or B - dry run protection) with
switch 1.
The switch on and/or off delay can be ad-
justed independently with the switches 2 and
3. The switch on or off delay refers to the
switching conditioning of the relay and tran-
sistor outputs.
On 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 adjusted
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
The integration time can be adjusted appro-
priately with the switches 4,5 and 6. The
times of the activated time switches. When
the switch on (ze) and off delay (za) are
switched on at the same time, the adjusted
time applies to both delay modes.
Switch 1 2 3 4 5 6
Time za ze 2 s 6 s 12 s
0,2 s A/B off off off off off
0,5 s A/B off off off
2 s A/B on off off
6 s A/B off on off
8 s A/B on on off
12 s A/B off off on
14 s A/B on off on
18 s A/B off on on
20 s A/B on on on
Optionally switch 2 and/ or 3 to "on“. The times are valid for the appro- priately adjusted delay mode.
