3.1 Connection instructions
Note the following instructions for electrical
connection:
- The connection must be made acc. to the
local installation standards (e.g. in Germany acc. to the VDE-regulations).
- The wiring between VEGAMET and sensor
can be done with standard two-wire cable.
- If strong electromagnetic interference is
expected, screened cable is recommended. The screening must be earthed
on both ends.
- The line resistances stated in the technical
data must not be exceeded.
- If overvoltages are expected, we recommend a sensor electronics with integrated
overvoltage protection or the installation of
VEGA overvoltage arresters.
- The voltage supply of VEGAMET must
provide extra-low voltage to ensure protection class II. When using VEGASTAB
593, a reliable separation from the mains
circuits acc. to DIN VDE 0106, part 101 is
ensured.

Adjustment
4.1 Indicating and adjustment
elements
A rotary switch is located on the circuit
board. It is used for adjustment of the instrument address on DISBUS. This setting is
necessary if measured values are to be
transmitted via the DISBUS cable to external
instruments, e.g. VEGADIS 174 indicating
instrument, VEGACOM 557 interface converter or other VEGAMETs. With these external instruments, a received measured value
can be associated with a specific measurement loop by means of the address.
The adjustment range 1 … F corresponds to
the DISBUS addresses 1 … 15.
Factory setting: 1
Note:
With address 0, the VEGAMET does not
participate in the DISBUS communication.

4.4 Configuration and parameter adjustment
No matter whether you set up your
VEGAMET via the keys of the adjustment
module or via a PC with the software VVO,
the procedure is always the same.
Proceed in the following sequence:
- configuration (if not already configured as
factory setting)
- parameter adjustment.
In this operating instructions manual, the
adjustment steps are described which are
carried out directly on the keys of VEGAMET.
The adjustment via the software VVO is described in a separate manual.
Configuration
Configuring means assigning or setting functions (once). VEGAMET requires a basic
configuration (usually once) that determines
the applications and the assignments of the
inputs and outputs. Choices can be made
from existing functions and options. This
procedure is called configuration. The signal
conditioning instruments are delivered with a
configuration which only needs to be
changed in special cases.
The basic configuration includes the following
steps:
1 Configuration measurement loop
• Choose the kind of application (level,
gauge…)
• Choose sensor type (capacitive, hydro-
static…)
• Determine application (standard, level
difference…)
• Determine options (no option, correc-
tions…)
2 Configuration inputs
• Specify from where your VEGAMET receives the input data (sensor, other
VEGAMET)
• Enter sensor characteristics values (meas.
range, current range)
3 Configuration outputs
• All outputs (except fail safe relay) can be
assigned to one sensor or can be switched
off.
After basic configuration, VEGAMET goes
into operating mode and indicates the actual
measured value. The other configurations
should be carried out after the parameter
adjustment.
Parameter adjustment
Parameter adjustment means changing the
values. Signal conditioning instruments have
many parameters, the values of which can be
modified, such as, for example, the integration time of 0 … 600 s. The modification of
these values is called parameter adjustment.
The parameter adjustment does not influence
the configuration. Take notice that parameter
adjustment is only possible after a configuration has been carried out (e.g. set values of
the current input after the current output has
been assigned).
Note:
The measurement loop configuration can only
be modified if a "Reset to single measurement“ or "Reset to linked measurement“ has
been carried out before (under "Additional
functions“).
VEGAMET 515V15
5 Setup
• Adjust the VEGAMET instrument address
with the rotary switch on the circuit board
(if measured values are to be transferred
via the DISBUS cable to external instruments, e.g. to VEGADIS 174 indicating
instrument, VEGACOM 557 interface converter or other VEGAMETs).
• Install VEGAMET.
• Connect sensor and power supply.
• After switching on, the display indicates for
approx. 10 secs the instrument type and
the software version, e.g. "MET 515V
V1.12“.
• If no measurement loop has yet been
configured, the display shows "Configuration“, the red fault indicator LED also lights.
In this case, proceed as described under
"6.1 Configuration measurement loop“.
• If a measurement loop has already been
configured, the display shows a value, e.g.
"TAG-No. 1 21.8 %“.You can now carry out
the settings, e.g. adjustment settings.

The measurement loop configuration is usually provided as a factory setting. Should a
general modification of the measurement loop
configuration be necessary, "Reset to single
measurement“ or "Reset to linked application“
should be carried out first (with "Reset to
single measurement“ the VEGAMET is prepared for configuration of two independent
single measurements. With "Reset to linked
application“ it is prepared for configuration of
linked applications). Only then can setting in
the menu items Application, Sensor type,
Mode and Option be modified. Proceed in
the menu items in the given sequence. The
adjustment or selection options always depend on what was set in the previous menu
item. When e.g. in the menu item Application
"Level“ is set, only one sensor type suitable
for level detection can be selected in the
menu item "Sensor type“.

As soon as you have made an adjustment in
the menu item "Option“ and confirmed it, the
display shows the message: "TAG being

In the following illustrations, different types of
applications are shown. In addition, you will
see which adjustments you have to carry out
in the menu items "Sensor type“ and "Mode“.
The menu item "Position D“ only appears
when in the menu item "Option“ either "Offset
correction“ or "Real value correction“ has
been set. The menu item "Position E“ only
appears when in the menu item "Option“
"Density correction“ has been set.
VEGAMET 515V17
Configuration
In the menu items "Pos. D“ and "Pos. E“ you
can determine if "Correction input 4“ or "Correction input 5“ is to be used for one of the
stated corrections. You then have to enter
under "Parameter adjustment“ – "Special
functions“ in the menu items "Real value correction at…“ or "Density correction at…“ a
value at which the correction should be carried out.
Note!
For tare and monitoring it is also possible to
assign input 4. However, a correction input
must not be used for tare, monitoring and
e.g. density correction at the same time!
In the menu item "TAG-Name“ you can enter
an individual name for the measurement loop.
If you choose "Fault signal off“, the fail safe
relay and the fault indicator LED in the front
plate do not function. For a description of the
correction modes, see the following pages.
