2 Mounting and installation instructions
Mounting
Each series 600 signal conditioning instrument consists of a plug-in socket for carrier
rail mounting DIN 46 277 and a module unit.
The supply voltage can be connected to
terminals 17 and 18.
For neighbouring series 600 signal conditioning instruments, it is possible to continue the
connection L1 and N directly via the supplied
jumpers. The same is valid for the connection
of VEGAMET voltage output 0 … 10 V (terminals 15 and 16) and for DISBUS output (terminals 9 and 10).
Note!
The jumpers must never be used with single
instruments or at the terminating end of an
instrument row. If this is not observed, there
is danger of coming in touch with the operating voltage or causing a short-circuit.
VEGAMET 614V Ex signal conditioning instrument is intrinsically safe and must not be
installed in hazardous areas.
Before setup, the Ex separating chamber
must be plugged into VEGAMET 614V Ex as
shown in the illustration.
Safe operation is ensured only if the operating instructions manual and the EC type
approval certificate are observed. VEGAMET
614V Ex must not be opened.

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 614 V and
sensor can be made with standard twowire cable.
- If strong electromagnetic interferences are
expected, we recommend the use of
screened cable. 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.
Connection instructions for Ex
approved applications
When wiring between VEGAMET 614V Ex
and an explosion protected sensor, the installation rules, in Germany acc. to VDE 165
and the EC type approval certificate must be
observed. The official documents are supplied with the respective instrument.

4.1 Indicating and adjustment elements
A rotary switch is located on the upper side
of the housing. It is used to set the instrument
address on DISBUS. This setting is necessary if several VEGAMET signal conditioning
instruments are linked via the DISBUS or if
you control a VEGADIS 174 indicating instrument via the DISBUS.
The adjustment range 1 … F corresponds to
the DISBUS addresses 1 … 15.
Factory setting: 1

"Reduced menu" – "Extended menu"
Two menu systems are available: the „reduced menu“ and the „extended menu“.
Note:
VEGAMET 614 V is preset to „reduced menu“
mode!
In the majority of applications, you can carry
out the necessary settings in this menu mode
(see also chapter 4.5 Comparison of the
menu modes).
Adjustment structure
The adjustment is made via 6 keys in conjunction with the text display. The jump from
the measured value display to the next lower
menu item is made with [OK]. Use [–>] or
[<–] to change within this menu level from
one menu item to the other. A branching point
is indicated by the symbol ▼ and enables
with [OK] a jump to the next lower menu item.
Parameters are indicated by the missing
symbol ▼. The value of the parameters can
be modified with [+] or [–] or chosen out of a
list. The modified value can be saved with
[OK]. To interrupt a setting (without saving
the modification), you have to push [ESC]. A
jump up to the next higher menu item is

Adjustment
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 with
a factory setting)
- parameter adjustment.
In this operating instructions manual, the
adjustment steps are described which are
directly carried out on the keys of VEGAMET.
The adjustment via the software VVO is described in a separate manual.
Configuration
Configuration means initially assigning or
setting functions. VEGAMET requires a
(mostly once) basic co-ordination 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 (hydrostatic, ultra-
sonic…)
• Determine application (standard, level
difference…)
• Determine options (no option, correc-
tions…)
Note:
The measurement loop configuration can only
be modified, if a „Reset to single measurement“ has been carried out previously (under
„Additional functions“ in the extended menu).
If you only want to modify the sensor type,
you first have to carry out „Reset TAG 1“
(under „Additional functions“ in the reduced
menu).
2 Configuration of inputs
• Determine from where your VEGAMET
receives the input data (sensor, other
VEGAMET)
• Enter sensor characteristics values (meas.
range, current range)
3 Configuration of outputs
• All outputs (except fail safe relay) can been
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 note 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).
