NOTICE
S&C Electric Company programs the Global Settings (Nominal Frequency,
Continuous Current, Interrupting Rating, and Trip Mode) at the factory to match
the configuration of the Vista switchgear. The Factory Default Reset setting
will restore the settings back to the overcurrent control pre-programmed state.
You MUST reprogram the Global Settings for the overcurrent control after
performing a factory reset to match the configuration of the Vista switchgear
that the overcurrent control is monitoring and controlling. Improper operation
of the control and/or switchgear may result if global settings do not match the
Vista Switchgear model. See “Programming the Control Settings” on page 28 for
instructions on how to reprogram the Global Settings.
The Factory Default Reset setting, which is available under the Control Settings tab,
will restore the control to its pre-programmed state. When a Factory Default Reset
command is initiated, the following settings will be restored:
• Global Settings:
• Continuous Current: 600 A
• Fault Interrupting Rating: 12.5 kA
• Trip Mode: Single-phase trip/single-phase lockout
• All protective settings under the Interrupter 1 and Interrupter 2 menus (These will be
restored to the “Factory Default Protective Settings.” See Figure 4.
• Both the admin and user passwords will be reset to the factory-default values.
