1.3 Types and versions
VEGATOR 620
Single point level switch (fixed switching hysteresis)
with selectable mode A/B (A = overfill protection, B = dry run
protection) and adjustable integration time
Inputs:
- active
1 capacitive probe,
1 hydrostatic pressure transmitter or
1 process pressure transmitter
- passive
for connection to an active circuit
Output:
1 relay (spdt)
Application:
level detection, overfill protection, dry run
protection
When using two VEGATOR 620 connected to one sensor, it
is possible to provide a dual single point control.
It is possible to connect up to 10 VEGATOR 620 to one
sensor, see „3.3 Connection diagrams“.
VEGATOR 621
Single point level switch (fixed switching hysteresis)
with fault monitoring, selectable mode A/B (A = overfill pro-
tection, B = dry run protection) and adjustable integration
time
Input:
1 capacitive probe or
1 hydrostatic pressure transmitter or
1 process pressure transmitter
Outputs:
1 relay (spdt)
1 transistor
Approval:
[EEx ia] IIC,
as part of an overfill protection acc. to WHG
Application:
level detection, overfill protection, dry run
protection
