Explanation
Timer Prohibit Rest. (517)
IntelliTEAM
Active when the Prohibit Restoration timer
for that team runs out. The timer com-
mand only affects the team on which it has
expired. When enabled the timer count-
down will be initiated at the same time a
transfer process begins at a team, usually
at the time a sectionalizing event occurs.
Although it will often be the case that tim-
ers in adjacent teams start simultaneously,
there is no requirement for this to occur.
Each team will decrement its timer inde-
pendently from other teams, and potentially
enter the Prohibit Restoration state asyn-
chronously.
WARNING
: Because teams may asyn-
chronously enter the Prohibit Restoration
state, one or more disconnected teams
throughout a circuit, or a system, may be
prohibited from further automatic restora-
tion activity, while others may continue as
necessary for subsequent events.
For this
reason it is extremely important that
standard safety practices are adhered
to when working on a circuit that has
been involved in automatic transfer and
restoration.
Disabling automatic operation
and tagging devices are strongly recom-
mended before performing any manual
switching or repair.
Xfer in progress (514)
IntelliTEAM
Active while the team is in the process of
reconfiguring the circuit and transferring
load to an alternate source.
Any Phase LOV (336)
UIM
Active when status points from the external
device report voltage losses or the analog
input from the external device is less than
the Auto setup voltage loss threshold.
E.D. Contacts Bad (355)
UIM
Active when the external device is reporting
that the switch open and closed status are
the same.
E.D. Comm Lost (353)
UIM
Active when the external device (E.D.)
stops communicating, e.g. due to a radio
problem.
E.D. Comm Stopped (352)
UIM
Active when BEGIN SETUP is set to
“Stopped”. Cleared when BEGIN SETUP is
set to “Running”.
E.D. Trouble (354)
UIM
Active when trouble status points are
programmed at the UIM and they become
active.
