1 Product description
1.1 Function and configuration
VEGATOR 620 … 622 signal conditioning
instruments are module units with plug-in
socket, suitable for carrier rail mounting (DIN
46 277). In conjunction with sensors they are
used for level detection and switching com-
mand output, which is triggered by relay and
transistor switches.
Typical applications are double point con-
trols, e.g. pump controls (on/off) and monitor-
ing functions such as overfill or dry run
protection.
The instruments are equipped with adjust-
able integration time. The integrated fault
monitoring (not with VEGATOR 620) detects
short circuit or interruption of the measuring
circuit. In case of failure, a failure LED lights
up. The level relay and the transistor output
deenergise.
To construct a measuring system you need a
VEGATOR … level switch and a sensor with
analogue measured data transmission, i.e.
- capacitive meas. probes,
- hydrostatic pressure transmitters or
- process pressure transmitters.
1.2 Approvals
If measuring systems are installed according
to the following approvals, the appropriate
official documents have to be noted and the
regulations observed. The documents are
supplied with the respective measuring sys-
tem.
WHG approval
VEGATOR 621 and 622 signal conditioning
instruments with capacitive meas. probes or
pressure transmitters as part of an overfill
protection according to WHG.
General type approval
no. Z.-65.13-105
Ex approval
When using measuring systems in Ex and
StEx areas, the instruments must be suitable
and approved for these applications and
explosion zones. The suitability is checked
by approval authorities and certified in ap-
proval documents. VEGATOR 621 Ex and
622 Ex are provided with Ex approval ac-
cording to CENELEC (PTB no.
Ex-96.D.2068).
CE conformity
VEGATOR 620, 621 and 622 signal condi-
tioning instruments see „1.4 Technical data“.
