VEGA VEGASEL 543, 544, 545, 546, 547 - Manual (Page 12)

12 VEGASEL
Set-up
Signal lamps
LEDs in the front panel indicate the operating status
and switch condition.
Green
- Operation control lamp(14)
- Mains voltage ON, instrument operates
Yellow
- Relay control lamp (12 and 13)
- The yellow control lamp reacts acc. to the adjusted
mode (A/B).
- Generally the relay control lamp indicates the
activated condition of the relay.
- An unlit control lamp means the relay is de-
energized.
Coded key
In the front panel the coded keys are located, by
which the switch point (single level switches) as well
as the switching hysteresis (two-point level switches)
can be adjusted. The values are stated in % and relate
to the current or voltage input. By pushing the "+" or "–"
key the falling or raising values are adjusted in 1 %- or
10 %-steps swiitch block.
DIL-switch block
The DIL-switch blocks are located on the circuit board
of VEGASEL:
-
1 … 4 DIL-switch blocks for the output (outputs
acc. to VEGASEL-type)
- 1 DIL-switch block for the input
The function label beside the DIL-switch block
describes the function of the individual switches.
Explanation of the function label
Mode B = protection against dry
running of pumps;
A = overfill protection
Hysteresis = 1 % or 3 %
Mode B = protection against dry
running of pumps;
A = overfill protection
without function
Input: 0 … 10 V/0 … 20 mA or
2 … 10 V/4 … 20 mA
U = voltage input
I = current input
The demonstration as example relates to VEGASEL
545. This type includes a single point level switch as
well as a two-point level switch.
The operation of the other level switches is the same.
The outputs can be adjusted independently.
