26 Capacitive electrodes EL 4 … 20 mA - compact
Set-up
4 Set-up
4.1 General adjustment
The figures in brackets relate to the pictures
under chapter “3 Electrical connection“. With
the set-up the electrode must be adjusted with
the original medium.
In certain cases also a dry adjustment can be
carried out.
The electrode can be adjusted in three different
ways:
• with integrated oscillator
• with operating software VEGA Visual
Operating (VVO from V. 2.30)
• with HART
®
-handheld
CAP E 32 Ex
Adjustment - directly on the oscillator.
CAP E 32 H Ex
Adjustment - directly on the oscillator
- via PC with adjustment
program VVO 1)
- via HART ® - handheld
Oscillator
The capacitive electrodes EL can be directly
adjusted on the oscillators CAP E32 Ex and
CAP E32 H Ex.
All sensor basic functions can be carried out
with the two keys and the rotating switch.
PC with adjustment program VVO 1)
With the adjustment program VVO V. 2.30
(VEGA Visual Operating) on the PC you can
adjust the capacitive electrode in conjunction
with oscillator CAP E 32 H Ex very comfortably.
Beside the sensor basic functions, also additio-
nal functions are available.
You require an interface adapter
VEGACONNECT 2, which you can connect to
any individual position of the signal line or
directly on the sensor.
System requirements:
- IBM-compatible PC with a free standard
interface. We recommend a PC with Pentium-
processor with a clock frequency of
100 MHz.
- Memory: 16 MB
- Software requirements: Windows 95
HART ® -handheld
The capacitive electrodes EL with oscillator
CAP E32 H Ex are suitable for HART
®
-protocols
and can be adjusted with a HART
®
-handheld.
All relevant sensor functions are possible with
the HART
®
-standard menus. A manufacturer
specific DDD (Data-Device-Description) is not
required.
1) When you want to adjust a sensor with the PC, you
have to connect the PC-lines on the signal line
outside the Ex-zone.
The intrinsic safety must be ensured with the
connection. Use a suitable interface converter e.g.
