You can find further information in the supplementary instructions manual "Safety Manual - Functional safety (SIL) VEGAVIB series 60". 2.7 Safety information for Ex areas Please note the Ex-specific safety information for installation and operation in Ex areas. These safety instructions are part of the operating instructions manual and come with the Exapproved instruments. 2.
Product description 3 Product description 3.
Product description Typical applications are overfill and dry run protection. Thanks to its simple and robust measuring system, VEGAVIB 66 is virtually unaffected by the chemical and physical properties of the solid. It functions even when exposed to strong external vibration or changing products. Solid detection in water If VEGAVIB 66 was ordered for solid detection in water, the tuning fork is to the density of water. In air or if covered by water (density: 1 g/cm³/0.
Product description On the electronics module you will find the following indicating and adjustment elements: l l l signal lamp for indication of the switching condition (green/ red) potentiometer for adaptation to the product density Mode switch for selecting the switching condition (min./ max.) 3.4 Storage and transport Packaging Your instrument was protected by packaging during transport. Its capacity to handle normals loads during transport is assured by a test acc. to DIN 55439.
Mounting 4 Mounting 4.1 General Switching point In general, VEGAVIB 66 can be mounted in any position. The instrument must be mounted in such a way that the vibrating element is at the height of the requested switching point. Moisture Use the recommended cables (see chapter "Connecting to power supply") and tighten the cable gland. You can give your VEGAVIB 66 additional protection against moisture penetration by leading the connection cable downward in front of the cable entry.
Mounting Warning: The housing must not be used to screw in the instrument! Applying tightening force on the housing can damage its internal mechanical parts. To screw in, use the hexagon above the thread. 4.2 Mounting information Tensile load Make sure that the max. permissible tensile load of the suspension cable is not exceeded. The danger of this happening exists particularly with very heavy solids and large meas. lengths. The max. permissible load is stated under "Technical data" in the "Supplement".
Mounting d 6 1 d 2 3 Fig. 1 2 3 4: Filling in the center, emptying laterally VEGAVIB 66 Emptying opening Filling opening Socket The vibrating element should protrude into the vessel to avoid buildup. For that reason, avoid using mounting bosses for flanges and screwed fittings. This is mainly applicable for adhesive products. Inflowing material If VEGAVIB 66 is mounted in the filling stream, unwanted switching signals may be generated.
Mounting Fig. 5: Inflowing material Flows To minimise flow resistance caused by the tuning fork, VEGAVIB 66 should be mounted in such a way that the surfaces of the fork are parallel to the product movement. 1 29289-EN-060508 2 Fig.

Set up 6 Set up 6.1 General The numbers in brackets refer to the following illustrations. Function/Configuration On the electronics module you will find the following indicating and adjustment elements: l l l Potentiometer for switching point adaptation (1) DIL switch for mode adjustment - min./max. (2) Signal lamp (5) Note: As a rule, always set the mode with mode switch (2) before starting the setup of VEGAVIB 66 . The switching output will change if you set the mode switch (2) afterwards.
Set up Switching point adaptation (1) With the potentiometer you can adapt the switching point to the solid. It is already preset and must only be modified in special cases. By default, the potentiometer of VEGAVIB 66 is set to complete right position (>0.02 g/cm³ or >0.0008 lbs/in³). In case of very light-weight solids, you have to turn the potentiometer to the complete left position (>0.008 g/cm³ or >0.0003 lbs/in³).

Maintenance and fault rectification 7 Maintenance and fault rectification 7.1 Maintenance When used as directed in normal operation, VEGAVIB 66 is completely maintenance-free. 7.2 Fault rectification Checking the switching signal Causes of malfunction VEGAVIB 66 offers maximum reliability. Nevertheless faults can occur during operation. These may be caused by the following, e.g.
Maintenance and fault rectification à Check if there is buildup on the vibrating element, and if so, remove it. l Unfavourable installation location à Mount the instrument at a location in the vessel where no dead zones or mounds can form. à Check if the vibrating element is covered by buildup on the socket. l Wrong mode selected à Set the correct mode on the mode switch (max.: overfill protection; min.: dry run protection). Wiring should be carried out acc. to the quiescent current principle.
Maintenance and fault rectification 1 2 Fig. 13: Loosen the screws 1 Electronics module 2 Screws (2 pcs.) 6 Remove the old oscillator 7 Compare the new oscillator with the old one. The type label of the oscillator must correspond to that of the old oscillator. This applies particularly to instruments used in hazardous areas. 8 Compare the settings of the two oscillators. Set the adjustment elements of the new oscillator to the settings of the old oscillator.
Maintenance and fault rectification 7.4 Instrument repair If a repair is necessary, please proceed as follows: You can download a return form (23 KB) from our homepage www.vega.com under: "Services – Downloads – Forms and Certificates – Repair form". By doing this you help us carry out the repair quickly and without having to call for additional information.
Dismounting 8 Dismounting 8.1 Dismounting procedure Warning: Before dismounting, be aware of dangerous process conditions such as e.g. pressure in the vessel, high temperatures, corrosive or toxic products etc. Take note of chapters "Mounting" and "Connecting to power supply" and carry out the listed steps in reverse order. With Ex instruments, the housing cover may only be opened if there is no explosive atmosphere present. 8.
