There are several fault flags in the database (e.g., DPID 20, 21, 22 which
indicate a cleared fault has occurred on the line). These flags can be
cleared by the SCADA system operator with a reset control (CPID 8) and/
or after a time-out. This setting determines if the fault flags will be
Yes
cleared after a time-out:
Yes, flags will be cleared by time-out.
No, flags will not be cleared by time-out.

See above.
When this setting is false, SCADA controls to Fusesaver are rejected if the
RCU remote control switch is off or a Fusesaver external lever is down.
This setting allows a modification of this behavior so that SCADA trip
controls can always be sent to Fusesavers.
True: The RCU will issue the trip command to the Fusesaver to trip
regardless of RCU remote control switch position and regardless of
Fusesaver external lever position. The Fusesaver will trip regardless of
policy file setting for manual inhibit (see Fusesaver operating
False
instructions IC1000-F320-A170-XX-XXXX).
False: If the RCU Remote Control switch is off or if the external lever
of the Fusesaver is down, then the RCU will reject the trip command
from the SCADA system.
Note: This setting only modifies the handling of SCADA Fusesaver trip
commands.
