Setup
4 Setup
4.1 General adjustment
In the setup procedure, the electrode must be
adjusted to the medium which will later be
measured.
In certain cases, a dry adjustment is also
possible.
The electrode can be adjusted in three differ-
ent ways:
• with the integrated oscillator
• with the adjustment software VEGA Visual
Operating (VVO from version 2.30)
• with a HART ® handheld
CAP E 32 Ex
Adjustment - directly on the oscillator.
CAP E 32 H Ex
Adjustment - directly on the oscillator
- via PC with the adjustment
program VVO 1)
- via HART ® handheld
Oscillator
The capacitive electrodes EK can be adjusted
directly on the oscillators CAP E32 Ex and
CAP E32 H Ex.
All basic sensor functions can be executed via
the two keys and the rotary switch.
PC with adjustment program VVO 1)
The capacitive electrodes, in conjunction with
oscillator CAP E 32 H Ex, can be very conven-
iently operated with the adjustment program
VVO (VEGA Visual Operating). Additional
functions are available beside the basic sen-
sor functions.
For this, you require an interface adapter
VEGACONNECT 2 which you can connect
directly to any position on the signal cable or
directly to the sensor.
System requirements:
- IBM compatible PC with a free serial port.
We recommend a PC with Pentium proces-
sor with a clock frequency of
100 MHz.
- Memory: 16 MB
- Software requirements: Windows 95
HART ® handheld
The capacitive electrodes EK with oscillator
CAP E32 H Ex are HART
® protocol capable
and can be adjusted with a HART ® handheld.
All relevant sensor functions can be executed
with the HART
® standard menus. A manufac-
turer-specific DDD (Data-Device-Description)
is not necessary.
1) If you want to adjust a sensor with the PC, you have
to connect the PC cables to the signal cable outside
the Ex zone.
The intrinsic safety must not be impaired by this
connection. Use a suitable interface converter, e.g.
