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
