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 614 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 614 Ex as shown in the illustration.
Coding
To avoid interchanging the various signal conditioning instruments, the plug-in socket is provided with pins and the signal conditioning instruments with corresponding gaps (mechanical coding).
Instrument coding ensures through differently positioned coding pins that the various series 600 signal conditioning instruments are not interchanged.
An Ex coding with inserted coding pins ensures that the non-Ex and Ex instruments are not interchanged.
On VEGAMET 614 Ex, the supplied coding pins (instrument coding pin
and Ex coding pin) must be inserted by the user according to the below table.

Mounting and installation instructions
Transparent cover
To protect the instrument against unauthorized adjustment, the front plate of VEGAMET can be equipped with two lockable transparent covers after setup. To remove the transparent cover, see illustration.

Electrical connection
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 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.
When wiring between VEGAMET 614 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.

Ex version
Before connecting Ex certified instruments, please note the instructions in the attached official documents as well as the valid installation regulations. Make sure that the Ex separating chamber is plugged in on the left instrument side before setup (see illustration Coding).

Adjustment
Position of the rotary switch
Rotary switch
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
Note:
If address 0 is set, the VEGAMET does not participate in the DISBUS communication.

Note:
VEGAMET 614 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 made with [ESC]. 15 minutes after pushing a key
for the last time, an automatic reset to the measured value display is triggered. A jump up to the next higher menu level with [ESC] is possible from each menu item, even if no connection is shown in the menu schematics.

If you are in the utmost right menu item of a menu row and push the [–>] key, you will immediately reach the utmost left menu item of this row. You also reach immediately the right menu item from the left one, if you push the [<–] key.
The connections (shown with a broken line) are not shown in the menu schematics in order to provide a clearer overview.

Adjustment
Formatting examples the menu schematic
White letters indicate parameters which can be modified with the [+] or
[–] key and saved with the [OK] key. Examples:
-In the menu item "Language“ you can change from German to English.
Setup
-directly via the keys of the adjustment module
-or with a PC, equipped with VVO software (VEGA Visual Operating) and an interface adapter VEGACONNECT.
Bolt print/italic inputs, e.g. the measurement loop name "TAG-No. 1" can
▼show a different text if you have carried out a parameter adjustment
or configuration of the measurement loop. In the menu schematics, you will see the factory setting.

at played if necessary (depending on

Changing the menu mode:
Move from the display of measured value (TAG-No.1) to the menu item "Menu mode reduced“. Now push [+] twice until "Menu mode Extended“ appears, then push [OK]. You can now return to the measured value indication by pushing [ESC] twice.

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 initial 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 (capacitive, hydrostatic…)
•Determine application (standard, level difference…)
•Determine options (no option, corrections…)
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).
