Page 4: Safety
The 762 VITO Interface is an instrument with intrinsically safe output/input circuits. Modification to the instrument may only be carried out by trained personnel which is authorized by Honeywell Enraf. Failure to adhere to this will invalidate the approval certificate. -
Page 5: Personal Safety
Safety Warning Improper installation of cable glands, conduits or stopping plugs will invalidate the safety approval of the 762 VITO Interface. “For electrical data see certificate”. Personal safety The technician must have basic technical skills to be able to safely install the equipment. When a probe is installed in a hazardous area, the technician must work in accordance with the (local) requirements for electrical equipment in hazardous areas. -
Page 6: Mechanical Installation
Mechanical installation Mechanical installation The mechanical installation is divided into the following sub-chapters: Installation of 764/767/361/MRT temperature probe (section 2.2) Installation of 765 water probe, 766/768/365 Combi probe (section 2.3) Installation of 762 VITO Interface (section 2.5) Caution The VITO Interface and probe may be installed in hazardous areas. - Page 7 Mechanical installation Notes: We do not recommend using liquid filled thermowells in tanks with heated products. Due to the heating at the lower end, the liquid may circulate in the well which results in a temperature mismatch. We do not recommend using liquid filled thermowells on floating roof tanks. Due to ambient temperature influence at the higher end, the liquid may circulate in the well which results in a temperature mismatch.

When anchor weights are attached, maximum static load is: 9 kg (20 lb) for 361 probe (when Honeywell Enraf anchor weight – p/n 0815524 – is used, only use 3 weights); 23 kg (50 lb) for 76x probes. Refer to figures 2 and 3. -
Page 9: Mechanical Installation Of 765/766/768/365 Vito Water (And Temp.) Probe
Caution When anchor weights are attached, maximum static load is: 9 kg (20 lb) for 365 probe (when Honeywell Enraf anchor weight – p/n 0815524 – is used, only use 3 weights); 23 kg (50 lb) for 76x probes. Note: The 765 VITO water probe, 766/768 VITO and 365 MPT water and temperature probe cannot be installed in a closed well. - Page 10 Mechanical installation Note: There should be at least 50 mm (2”) free space between the sensitive part of the water probe and the tank shell (or any other large metal part in the tank, i.e. stilling well). Figure 4 Installation methods for 765 VITO water probe, 766/768 VITO and 365 MPT water &...
- Page 11 Mechanical installation Installation: Refer to figures 2 and 4. Remove optional lower IP adapter (7), nuts (3 pc.), instrument label(s) (5) and lock washers (2 pc.) from the adjusting pipe (1); Screw the flange (2) with G ½ threaded hole on the adjusting pipe till the marked position.

Page 12: Removing Vito Temperature Probe On Cryogenic Tank
Mechanical installation Removing VITO temperature probe on cryogenic tank Warning Open the vent screw when removing the VITO temperature probe from a cryogenic tank. This must be done to prevent the hose of the VITO temperature probe to shrink in an uncontrolled matter, which can harm persons. -
Page 13: Installation 762 Vito Interface
Mechanical installation Installation 762 VITO Interface The VITO interface is typically installed directly on top of the VITO probe / MRT (refer to section 2.5.1) For installations where the VITO interface cannot be installed directly on the VITO probe / MRT (e.g. -

Page 16: Installation Of Vito Interface In Close Proximity Of Vito Probe / Mrt
Mechanical installation 2.5.2 Installation of VITO Interface in close proximity of VITO probe / MRT In some cases there is not sufficient space to install the VITO interface on top o f the VITO probe / MRT. In these cases a (preferable flexible) metal conduit is advised, although also a set of matching coupling and unions can be considered. -
Page 17: Electrical Installation
Electrical installation Electrical installation The entire electrical installation shall be in accordance with the International Standard IEC EC 60079-14 (Selection and Installation). Warning Make sure that all power to the associated instrument is switched off before opening the cover of the 762 VITO Interface. Failure to do so may cause danger to persons or damage the equipment. -
Page 18: Vito Interface Wiring To Tank Level Gauge
Electrical installation VITO Interface wiring to tank level gauge The VITO-MTT/LT/MRT Interface connection to associated Honeywell Enraf instrument is by a single twisted pair cable. The single pair provides both intrinsically safe supply to the interface as well as data communication between the interface and the associated gauge. -
