596 Ex.M or in a single housing type 505.

Mounting in carrier

Mount the respective module (standard or Ex version) in your carrier. Wire the terminals of the multipoint connector according to the wiring plan.

Module

Multipoint connector DIN 41 612, series F, 33pole (d, b, z) with coded pins and mounting material for mounting in carrier BGT 596 or BGT 596 Ex.M.

Module Ex

Multipoint connector DIN 41 612, series F, 33pole (d, b, z) with coded pins, Ex separating chamber and mounting material for mounting in carrier BGT 596 Ex.M.

The multipoint connector is available in the following versions:

-Wire-Wrap standard connection

1.0x 1.0 mm

-Plug connection 2.8 x 0.8 mm

-Termi-Point standard connection

1.6x 0.8 mm

-Soldering connection

-Screw terminals 2 x 0.5 mm2

For further mounting information, see the operating instructions of the carrier.

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.

Electrical connection

3 Electrical connection

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 recommend 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.

3.2Connection 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.

Reduced menu - extended menu

Two menu modes are available: the mode "reduced menu" and the mode "extended menu".

Note:

VEGAMET 514 is preset to automatically place in the menu mode "reduced menu"!

In the majority of all 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 underlying menu 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 underlying menu item. Parameters can be recognised by the absence of the 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 back 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 back to the next higher menu level with [ESC] is possible from each menu item , even if no connecting line is shown in the menu schematics.

4.4Configuration 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, hydrostatic…)

•Specify 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 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).

Setup

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.

Push [+] or [–] once. The first character of the measurement loop name, in this example the letter T, flashes (editing mode). Continue pushing the

[+] or [–] key, by doing this you scroll through the alphabet, through the row of numbers and through a list of characters.

When you have reached the requested character, push [–>]. The next character is activated and begins flashing. Scroll again with [+]

and [–] to the requested character. With [–>] you again move to the next character.

When you have finished the last position of the name and you have "written" the name of the measurement loop in this way, you have to

push [OK] to save the setting. If you quit the menu item without saving, the name of the measurement loop is again "TAG-No. 1".

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".

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.

Adjustment example

You know that your vessel is actually filled up to 80%. Move to the menu

100,0 item "Max. adjust at % 100.0". Push the [–] key briefly, so that the figure

100.0 flashes (editing mode).

Max-	Continue pushing [–] until the figure
adjust	80.0 appears on the display. Now
at %	push [OK] to save the adjustment.
80,0
Min-	Later, when your filling is, for exam-
adjust	ple, 10 %, go to the menu item
at %	"Min. adjust at % 0.0". Briefly push

	[+], until the figure 0.0 flashes
	(editing mode).
Min-	Continue pushing [+] until "10" ap-
adjust	pears on the display. Now push [OK]
at %

10,0 to save the adjustment.

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.
