Source Air Pressure Requirements
The
Constellation
®
Vision System is designed to operate using different levels of
source air pressure. The system operates automatically with pressures of 58 (4 bar) to
120 psi (8.3 bar). Between 4 bar and 5 bar, vacuum performance is reduced. Between
4 bar and 5.5 bar, VFC inject performance is reduced.
Accessory equipment connected to or used with this equipment must be certified
according to the respective IEC Standard (e.g., IEC 60950 for data processing
equipment, and IEC 60601-1 for medical equipment). The Constellation
®
is shipped
with English and metric air fittings compliant with EN739:1998. Anyone connecting
additional equipment or otherwise causing a different system configuration than
provided by Alcon is responsible for continued compliance to the requirements
of System Standard IEC 60601-1-1. If in doubt, consult the Technical Services
department or your local Alcon representative.
Settings Restoration
When a loss of power occurs, the Constellation
®
Vision System retains its current
settings and mode in memory. When power is reestablished a System Information
popup window appears asking:
"Do you want to restore the system's previous settings and mode?"
The user can press Yes to restore the previous settings, or No to enter the default
settings. Disconnecting the power cord, or turning the system off using the rear panel
power switch, is considered a loss of power; using the rear panel standby switch is
not.
