Take note of safety instructions for Ex applications

Please note the Ex specific safety information which you will find on our homepage www.vega.com\services\downloads and which come with the appropriate instrument with Ex approval. In hazardous areas you should take note of the appropriate regulations, conformity and type approval certificates of the sensors and power supply units. Each VEGATOR with Ex approval is an associated, intrinsically safe instrument and must not be installed in hazardous areas.

Conductive – Signal conditioning instruments for level switches

Product description

1 Product description

VEGATOR

VEGATOR signal conditioning instruments power the connected sensor and output level-dependent switching signals via integrated relay outputs.

VEGATOR 256C, 532 and 632 signal conditioning instruments are suitable for level detection in conjunction with conductive probes series EL.

Functional principle

An alternating voltage is connected to two electrodes with the conductive measurement. The medium is in contact with the electrodes and conducts the current according to the resistor. E.g.

reaching of a certain level in a vessel is detected by the sensor and transferred to the VEGATOR signal conditioning instrument for further processing. The measuring system can be adapted to the conductivity with VEGATOR.

Area of application

The instruments are mainly used for level detection or pump control.

The different signal conditioning instruments have various mounting options.

VEGATOR 256C

VEGATOR 256C can be mounted in the following ways: l

Carrier rail 35 x 7.5 according to EN 50022 l

Wall mounting

You can either mount the signal conditioning instrument directly on the wall with 2 screws or plug it onto a carrier rail.

l l l l

Plug connection 2,8 x 0.8 mm

Termi-Point standard connection 1,6 x 0.8 mm

Soldering connection

Screw terminals 2 x 0.5 mm²

You can find further information on mounting in the operating instructions manual of the carrier.

Carrier rail mounting

Place the signal conditioning instrument onto the carrier rail

(35 x 7,5 according to EN 50022) from below and press the instrument against the carrier rail until it snaps in.

Wall mounting

Fasten the instrument directly to the wall by means of two screws

(max. ø 3 mm/0.12 in).

When you are mounting the signal conditioning instrument with Ex approval in a carrier, you have to use a

VEGA Ex module.

In Ex applications, a protection of IP 20 must be maintained. Cover the gaps or free module from the front with appropriate blind covers.

Keep a distance of at least 2 TE (10 mm/0.4 in) to the module cards of other manufacturers.

If you want to mount VEGATOR 532 in the complete left position in the carrier, you have to mount a blind cover with at least 4 TE (20 mm/0.8 in) in front of the module of the signal conditioning instrument.

Selecting connection cable

Power supply of VEGATOR is connected with standard cable according to the national installation standards.

Standard two-wire cable without screening can be used to connect sensors. If electromagnetic interference is expected, screened cable must be used.

Cable screening and grounding

Connect the cable screen on both ends to ground potential. In the sensor, the screen must be connected directly to the internal ground terminal. The ground terminal outside on the housing must be connected to the potential equalisation.

If potential equalisation currents are expected, the screen connection on VEGATOR must be made via a ceramic capacitor (e.

g. 1 nF, 1500 V). The low frequency potential equalisation currents are thus suppressed, but the protective effect against high frequency interference signals remains.

Select connection cable for Ex applications

Take note of the corresponding installation regulations for Ex applications. In particular, make sure that no potential equalisation currents flow over the cable screen.

In case of grounding on both sides this can be achieved by the use of a capacitor or a separate potential equalisation.

Note:

Mutiple rod probes connected to several signal conditioning instruments or to a multiple channel instrument need a ground rod to keep the signal conditioning instruments from influencing each other.

If there are several VEGATOR, it is absolutely necessary that they be connected identically, i.e. the first supply line to all no. 7 terminals and the second supply line to all no.

Fault signal adjustment, bridge

To monitor the electrodes and their circuits, a resistor of 220 kΩ must be mounted between connection 1 and connection 2 in the connection housing of the probe, i.e. with single point control, the measuring and earth electrodes are monitored, and with double point control, the max. and earth electrodes are monitored.

If you want to use both channels for two separate measurements

(no two-point control), the measuring electrodes are monitored, e.

g. ground and max. electrode of channel 1 (connection d30 and d32) and ground and min. electrode of channel 2 (connection z30 and z32).

By doing this, a failure is triggered separately for each channel. In case of failure: l the channel-specific control lamp fault signal lights l l the relay output of the concerned channel deenergises the transistor output of the concerned channel is blocked l

The functions of the inteferred channel remain

For probes with 220 kΩ resistor, a soldering bridge must be closed on the circuit board of VEGATOR.

The set time applies to the switch on as well as the switch off delay.

Fault signal adjustment, bridge

To implement line monitoring, you have to mount a resistor of

220 kΩ between terminals 1 and 2 in the connection housing of the probe. This means that with single point control, the measuring and ground electrode are monitored and with two-point control, the max. and ground electrode.

Operation

When a fault message is generated, the switching output is simultaneously activated.

1 Resistor (220 kΩ)

If a fault message is not wanted, a bridge must be provided on the signal conditioning instrument instead of the resistor in the connection housing of the probe.

Note:

The line monitoring and the fault signal are inactive with this bridge.

If a measuring system is used as part of an overfill protection system, the bridge on the signal conditioning instrument must not be closed. With Ex probes, the resistor in the probe housing is already present.

You can find the electrical connection of VEGATOR in the operating instructions manual of the corresponding signal conditioning instrument.

With Ex versions, this resistor of 220 kΩ is already integrated Ex factory in the connection housing of the probe.

The Ex measuring system (max. and ground connection cable of the probe to the signal conditioning instrument) is generally monitored for line break.
