<strong>SVI</strong> <strong>II</strong> <strong>AP</strong> Instruction Manual<br />
Optional Display <strong>and</strong> Pushbuttons<br />
The optional display <strong>and</strong> buttons are mounted on the <strong>SVI</strong> <strong>II</strong> <strong>AP</strong> cover plate. The three<br />
pushbutton switches operating in conjunction with the display permit reading <strong>and</strong><br />
modification of the instrument operating parameters without a PC or HART h<strong>and</strong>-held<br />
communicator. These switches perform generic functions - Increase, Decrease, <strong>and</strong><br />
Accept by movement through a conventional menu structure, see “Using the Digital<br />
Interfaces” on page 71. The switches are operated in a hazardous environment without<br />
compromising the flameproof enclosure.<br />
<strong>SVI</strong> <strong>II</strong> <strong>AP</strong> <strong>Maintenance</strong> <strong>and</strong> Repair<br />
The <strong>SVI</strong> <strong>II</strong> <strong>AP</strong> was designed based on a modular concept. All components are<br />
interchangeable allowing for easy, quick component swapping.<br />
The only maintenance procedures recommended for the <strong>SVI</strong> <strong>II</strong> <strong>AP</strong> are:<br />
Remove <strong>and</strong> install the cover, for upgrade to display<br />
Remove <strong>and</strong> install the I⁄P module<br />
Remove <strong>and</strong> install the Pneumatic Relay<br />
WARNING<br />
Do not remove the instrument cover or connect to an<br />
electrical circuit in a Hazardous Area unless the power is<br />
disconnected.<br />
Repair<br />
Replacement of the Pneumatic Relay, I/P <strong>and</strong> cover (with or without display) are the only<br />
field repairs permitted.<br />
Only qualified service personnel are permitted to make repairs.<br />
Only parts supplied by the factory are permitted. This includes not only the major<br />
assemblies but also mounting screws <strong>and</strong> O-rings. No substitutions with non-<strong>Masoneilan</strong><br />
parts are permitted.<br />
