INSTRUCTIONS FOR MOUNTING Before to mount VEGA T the following recommendations have to be considered: 1. VEGA T mounting position has to be chosen to allow easy opening and wiring 2. The position must avoid damages caused from the passage of the trucks but also to assure good visibility of the indications 3. Avoid exposing the device to the rain and to the solar beams directly: a simple canopy of protection is to be forecast 4. Mounting has be done by using the 4 silent blocks located under the housing (see fig.2) 5. Before opening the device read the safety instructions at paragraph 2 6. The opening is done by removing the 14 screws that close the cover (see fig.2) – Take attention that the gasket remains in its own position.
WARNING: VEGA T MUST BE PROTECTED FROM DIRECT SUNLIGHT SUNLIGHT

WARNING 5.
In order to prevent VEGAT buffer battery from being completely depleted, it is necessary to connect VEGAT to power network for 24 hours straight at least once per month. Buffer battery is used to maintain in memory the delivery data and parameters par ameters customization.
ELECTRICAL CONNECTIONS VEGAT is provided with 7 cable entries. The five left side entries are foreseen for power supply, pulses from encoder, output for valves, etc. The two right side si de cable entries can be used only for the intrinsically safe connections (PT100, digital inputs). Take care to choose accessories threaded ISO 7/1 (UNI 6125-74) . VEGAT is delivered with gland en entries tries closed by plastic threaded screw-caps. These threaded screw-caps must be removed and the not utilized entries must be closed with metallic screws-plugs conforming to EN60079-1 norm.

SUGGESTIONS: The cables can be different types but with the same characteristics Suitable anti over-voltages protection devices must be considered aga against inst atmospheric (Suggested: ISOIL PL360/2) PL360/2) The communication lines must be segregated from power leading cables. Ducts must be separated For W&M reasons is preferable that communication lines for SPD and for other systems (PC, PLC, DCS…) are separated. Using the same multi-cable can occur
problemsthe in case a sealing the path is required. Limiting number of theofdevices connected in multi-point; avoid for example to connect together all the VEGAII for the same product. Consider to use more SPD and printers. Choosing cables suitable as electrical characteristics and mechanical strength.

ISOIL PULSE EMITTER “EM6422”
Pulse emitter “Encoder EM6422”, developed by ISOIL IMPIANTI, converts the rotary motion of a Positive Displacement Meter into electric pulses representing the delivered volume. It allows the pdmeter to interface with an electronic control device (electronic register, flow computer). The pulse emitter can be factory installed directly on to the front cover af any new Isoil pdmeter. By the use of suitable flanges it can be retrofitted onto any existing ISOIL pdmeter, in place of the mechanical register or other pulse emitters. Installation on most other manufacturer’s pdmeter is possible as well by means of specialutilizes adaptors. Unlike most similar devices, which use optical sensors, the EM6422 a state-of–the-art method, that detects the rotary motion of the pdmeter’s shaft through a thin separating wall. The electronic circuit is placed in a sealed housing completely insulated from the process fluid in the pdmeter. The housing is closed by a cover with o-ring seal and there is a threaded female inlet for cable glands or counduit entrance. In the following tables are included the nominal number of pulses for litre emitted by EM6422 when is mounted directly on the relative ISOIL METER. The “number of pulses” must be programmed inside the parameter K-FACTOR of the VEGAT.
