Vicon SurveyorVFT, Quick Manual, Page: 19 / 25

Alarm Handling — Configures the SurveyorVFT’s four alarm inputs.
Relay Driver — Adjusts and configures the relay output for control of external devices.
Source Titling — Programs and displays the various titles available to the SurveyorVFT.
Note: All titles are disabled from the factory and will not be displayed upon initial startup.
Preset/Tour Handling — Programs preset events into the camera dome. It also allows
programming a series of events or actions into a script called a Tour and Autotour and on
23X/35X versions, Motion Detection zone set up.
Scheduler/Time of Day — The Scheduler provides a means of programming events to occur at
specific times of the day. The Time of Day feature allows programming of the time display
format. It allows selection of daylight saving time, 12/24-hour format and actual setting of the
time and date.
Language — Programs language format for titles and menus. Language choices are English,
Spanish, French, German and Italian. The word “Language” will continuously change between
the five translated words, Language, Idioma, Langue, Sprache and Lingua, to alert an operator
that this prompt is related to changing the language. When selected, the menus will immediately
display the new language.
Install Defaults — Resets the SurveyorVFT to the factory default settings. All previously
programmed titles and settings are lost when this function is accessed, so keep a record of
programmed settings. The main default settings are listed in the Install Defaults section. Some
default settings are camera dependent; those are not listed.
Note: On unit power up, when DIP switch SW2 positions 2, 6, 7 and 8 are all set to ON, the unit will perform
an Install Defaults.
Pressurization
Pressurizing the Housing Assembly (SVFT-PRS)
1. Reattach the previously removed service cover to the service opening using the four (4) captive screws.
2. Using a regulated source of dry Nitrogen gas with the proper Schraeder type fill fitting, as shown in
Figure below, regulate the gas pressure to 10.0 psi (0.68 atm or bars).
3. Attach the fill fitting to the housing assembly’s fill valve located at the lower side of the housing and
pressurize the housing assembly. When the relief valve opens (gas will hiss from the top of the relief
valve), allow this to purge for a minimum of 5 minutes to assure that all the enclosed air is replaced by
nitrogen; then remove the fill fitting. The relief valve is rated at 5 psi +/- 0.5 psi (0.34 atm or bars +/-
0.03 atm or bars). Monitor the actual pressure for the next hour. If, in one hour the pressure has not
dropped below 4.5 psi (0.31 atm or bars), it is assumed that the housing assembly is sealed and the
relief valve is seating properly.
4. Reinstall the cap on the fill valve.
Caution: Pressurizing the housing assembly beyond 10 psi, or with an unregulated gas source, can
cause severe injury to personnel and permanent damage to the assembly. When connecting
a gas source to the housing for pressurization and initial purging, it is critical to ensure the
gas source is regulated to a maximum of 10 psi. Failure to regulate the inlet pressure to this
value can result in an over pressure condition, which can result in a housing failure. This
could potentially lead to personal injury and damage to the housing.
