Mounting in single housing

Either screw the housing socket directly to
the mounting plate or plug it onto a carrier rail
(35 x 15 acc. to EN 50 022 or 32 acc. to
EN 50 035). Connect the terminals according
to the wiring plans on the following pages.
For further mounting information see the oper­ating instructions of the housing.

Transparent cover

To protect the instrument against unauthor­ised adjustment, the front plate of VEGAMET
can be provided with a lockable transparent
cover (supplied with the instrment).

Coding

To prevent an interchanging of the different
signal conditioning instruments, the multipoint
connector of carrier or the housing can be
provided with coded pins.

Note:

The coding is absolutely necessary for Ex
instruments!

The multiple plug of the signal conditioning
instrument is equipped with respective holes
(mechanical coding). Instrument coding
ensures that the different signal conditioning
instruments cannot be interchanged. The
appropriate coded pins are supplied with
each module or housing. Equip the multipoint
connector with these coded pins acc. to the
following table.

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 interferences are

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 recom-

mend a sensor electronics with integrated
overvoltage protection or the installation of
VEGA overvoltage arresters.

- The voltage supply of VEGAMET must

provide with 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.

3.2 Connection instructions
for Ex approved applica­tions

The signal conditioning instruments must be
generally mounted outside the hazardous
areas, or special Ex protective measures
must be taken.

Ex separating chamber

To ensure sufficient "air and creep distance",
an Ex separating chamber must be mounted
to the connections of VEGAMET. Lead the
cables through the Ex separating chamber
and connect them. Fasten the Ex separating
chamber with the lower screw. Note the
operating instructions of the carrier BGT 596
Ex.M.

Protection in Ex applications

In Ex applications a protection class of IP 20
must be maintained. To accomplish this,
cover the gaps or free modules from the front
with suitable blind covers.

Mounting in carriers

If you mount your VEGAMET with Ex ap­proval in a carrier, you have to use a VEGA­Ex module. Keep a distance of at least 10
mm (2 TE) to module cards of other manufac­turers. If you want to mount VEGAMET at the
utmost left position in the carrier, you have to
mount a blind cover with at least 20 mm
(4 TE) in front of the module of the instrument.

4.4 Configuration and parameter adjustment

Independent of 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 instruction 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

Configuring means assigning or setting
(once) function. VEGAMET requires a (mostly
once) basic co-ordination, determining 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…)

• Specify 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 previosly (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, inputs

• Determine 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 a sensor or can be switched
off.

After basic configuration, VEGAMET starts
operating 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 done (e.g. set values of the
current input when the current output has
been assigned).

5 Setup

• Adjust the VEGAMET instrument address
on the circuit board by means of the rotary
switch (only necessary, if several
VEGAMET are connected by means of
DISBUS).

• 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 514
V1.12".

• If a measurement loop has not yet been
configured, the display shows "Configura­tion", the red failure LED also lights. In this
case, proceed as described under "6.1
Configuration of measurement loop".

• If a measurement loop is already
configured, the display shows a value, e.g.
"TAG-No. 1 21.8 %".You can now carry out
the settings, as described in the chapter "6
Settings in the reduced menu".

By default, VEGAMET 514 is configured for
connection to a hydrostatic sensor. If, for
example, you use a capacitive electrode, you
have to proceed as follows:
Move to the menu item "Sensor type
Hydrostatic".
Push [+] or [–] once. The word "Hydrostatic"
flashes. You are now in the editing mode.
Continue pushing [+] or [–] until the display
shows "Sensor type capacitive". You are still
in the editing mode.
Now push the [OK] key. By doing this, you
save the settings and quit the editing mode.

6.2 Adjustment with medium

You can either carry out the adjustment with
medium or without medium. Adjustment with
medium means that you carry out the adjust­ment taking the actual level into account. To
carry out an adjustment with medium, it is
necessary to know the percentage value of
the actual vessel filling.

In this procedure, the percentage values
which correspond to the actual min. and max
fillings are entered. The adjustment sequence
of the min. and max. value is unimportant.
When you know, for example, that your filling
is actually 80 %, you can enter in the menu
max. adjustment the value "80". Later when
your filling is, for example, 10 %, you enter in
the menu min. adjustment the value "10".

Adjustment example

You know that your vessel is actually

filled up to 80%. Move to the menu

item "Max. adjust at % 100.0". Push

the [–] key briefly, so that the figure

100.0 flashes (editing mode).

Continue pushing [–] until the figure

(editing mode).

Continue pushing [+] until "10" ap-

pears on the display. Now push [OK]

to save the adjustment.

10,0

You can of course carry out the adjustment
with medium at 0 % and 100 % filling. Note:
The figures 0 % and 100 % must flash (edit­ing mode), before they can be saved with the
[OK] key.

The bigger the difference between the two
adjustment points, the more precise the
measurement over the whole measuring
curve. An adjustment at 0 % and 100 %
would be ideal. For practical reasons, it is not
always possible to completely empty or fill a
vessel. The distance between the two adjust­ment points, however, should be at least
10 % of the sensor range.
