Scope of delivery	The scope of delivery encompasses:
	• Indicating and adjustment unit
	• Documentation
	- this operating instructions manual
	- Ex-specific "Safety instructions" (with Ex versions)
	- if necessary, further certificates

	3.2 Principle of operation
Application area	The VEGADIS 62 is an external indicating and adjustment unit without
	external energy for 4 … 20 mA/HART sensors. The instrument is used
	for remote measured value indication and adjustment. It is looped in
	any position directly into the signal cable.
	The housing of VEGADIS 62 contains a filter element for ventilation.
	Hence the insturment is also used for atmospheric pressure
	compensation of a connected suspension pressure transmitter
	VEGAWELL 52.

	Fig. 2: Connection of the VEGADIS 62 to a suspension pressure transmitter
	The VEGADIS 62 can be also used as external indication for a four-
	wire sensor or a VEGAMET signal conditioning instrument with active
	4 … 20 mA output.
Operation	The VEGADIS 62 is suitable for operation of all continuously
	measuring VEGA sensors with HART output > 5.0:

•Radar and ultrasonic sensors

•Sensors with guided microwave

•Capacitive probes

•Pressure transmitter

•Previous instrument versions (replacement for VEGADIS 12)

The operation of respective sensors from other manufacturers is also possible.

The VEGADIS 62 acts like a HART handheld with limited functions. The following adjustment functions are available:

•Min./Max. adjustment

•zero/span adjustment (live adjustment)

•Damping

Basic mode: when used in a 4 … 20 mA signal cable, the VEGADIS 62 works as a pure indicating instrument. It measures the current in the current loop and shows it as digital value as well as via a bargraph. All settings of VEGADIS 62 are carried out manually via the buttons in the front.

Adjustment volume: Indication scaling

HART standard: when used with a 4 … 20 mA/HART sensor, the VEGADIS 62 operates as automatic indicating and HART adjustment instrument. The VEGADIS 62 powered via the current loop listens continuously to the HART communication of the control system with the sensor. Changes of unit and/or measuring range are adapted automatically.

The parameter adjustment of the sensor is carried out via HART communication. During the parameter adjustment, the VEGADIS 62 operates as a Secondary Master to the sensor.

Adjustment volume: Sensor functions, indication scaling

HART multidrop: The VEGADIS 62 can also be used as indicator for a bus participant on a HART multidrop system. For this purpose, it is looped into the bus and the address of the participant is set in the VEGADIS 62. The instrument reads out the measured values with unit via the HART signal and displays them.

Adjustment volume: Sensor function damping, indication scaling

3.3 Packaging, transport and storage

Your instrument was protected by packaging during transport. Its capacity to handle normal loads during transport is assured by a test according to DIN EN 24180.

The packaging of standard instruments consists of environmentfriendly, recyclable cardboard. For special versions, PE foam or PE foil is also used. Dispose of the packaging material via specialised recycling companies.

Moisture	Use the recommended cables (see chapter "Connecting to power
	supply") and tighten the cable gland.
	You can give your instrument additional protection against moisture
	penetration by leading the connection cable downward in front of the
	cable entry. Rain and condensation water can thus drain o . This
	applies mainly to outdoor mounting as well as installation in areas
	where high humidity is expected (e.g. through cleaning processes) or
	on cooled or heated vessels.

		5 Connecting to power supply
		5 Connecting to power supply
		5.1 Preparing the connection
Safety instructions		Always keep in mind the following safety instructions:
		• Connect only in the complete absence of line voltage
		• If voltage surges are expected, install overvoltage arresters
Voltage supply		Power supply and current signal are carried on the same two-wire
		cable. The voltage supply range can di er depending on the sensor.
		The data for power supply are specified in chapter "Technical data".
		Provide a reliable separation between the supply circuit and the mains
		circuits according to DIN VDE 0106 part 101.
		Keep in mind the following additional factors that influence the
		operating voltage:
		• Output voltage of the power supply unit can be lower under
		nominal load (with a sensor current of 20.5 mA resp. 22 mA in
		case of fault message)
		• Influence of additional instruments in the circuit (see load values in
		chapter "Technical data")
		Operation of VEGADIS 62 in a HART multidrop system with the signal
		conditioning instruments VEGAMET 625 or VEGASCAN 693 is not
		supported.
Connection cable		The instrument is connected with standard two-wire cable without
		screen. If electromagnetic interference is expected which is above the
		test values of EN 61326-1 for industrial areas, screened cable should
		be used.
		For instruments with housing and cable gland, use cable with round
		cross-section. A cable outer diameter of 5 … 9 mm (0.2 … 0.35 in)
		ensures the seal e ect of the cable gland. If you are using cable with a
		di erent diameter, exchange the seal or use a suitable cable gland.
		We generally recommend the use of screened cable for HART
		multidrop mode.
Cable gland ½ NPT		With plastic housing, the NPT cable gland or the Conduit steel tube
		must be screwed without grease into the threaded insert.
		Max. torque for all housings see chapter "Technical data"
Cable screening and		If screened cable is necessary, connect the cable screen on both ends
grounding		to ground potential. In the sensor, the screen must be connected
		directly to the internal ground terminal. The ground terminal on the
		outside of the housing must be connected to the potential equalisation
		(low impedance).

5 Connecting to power supply

					If potential equalisation currents are expected, the connection on the
					processing side 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 e ect against high frequency interfer-
					ence signals remains.
					Warning:
					Significant potential di erences exist inside galvanization plants as
					well as on vessels with cathodic corrosion protection. Considerable
					equalisation currents can flow over the cable screen if the screen is
					grounded on both ends.
					To avoid this in such applications, the cable screen must be connected
					to ground potential only at one end (in the switching cabinet). The
					cable screen must not be connected to the internal ground terminal in
					the sensor and the outer ground terminal on the housing must not be
					connected to the potential equalisation!
					Information:
					The metal parts of the instrument (antenna, transmitter, concentric
					tube, etc.) are conductive connected with the inner and outer ground
					terminal on the housing. This connection exists either directly metallic
					or with instruments with external electronics via the screen of the
					special connection cable.
					You can find specifications to the potential connections within the
					instrument in chapter "Technical data".
					5.2 Connection technology and steps
Connection technology					The connection of the signal cable is carried out via spring-loaded
					terminals in the housing.
					The indicating and adjustment module is connected via a cable with
					coupling to the housing.
Connection procedure					Proceed as follows:
					1 Unscrew the housing cover

6Insert the wire ends into the terminals according to the wiring plan

Note:

Solid cores as well as flexible cores with cable end sleeves are inserted directly into the terminal openings. In case of flexible cores without end sleeves, press the terminal with a small screwdriver; the terminal opening is freed. When the screwdriver is released, the terminal closes again.

7Check the hold of the wires in the terminals by lightly pulling on them

8Connect the screen to the internal ground terminal, connect the outer ground terminal to potential equalisation

9Attach the indicating and adjustment module again and turn it slightly to the right

10Tighten the compression nut of the cable glands. The seal ring must completely encircle the cable

11Screw the housing cover back on

The electrical connection is finished.

Note:

The terminal block is pluggable and can be removed from the electronics. To do this, lift the terminal block with a small screwdriver and pull it out. When inserting the terminal block again, you should hear it snap in.
