Sequence Coordination (ON/OFF)
ON
•
Select Sequence Coordination ON and OFF using
the CHANGE key.
•
Sequence Coordination automatically advances the
control sequence one step if both of the following
conditions are met:
a.
Line current exceeds the programmed minimum
trip value for a time duration shorter than the pro-
grammed control response time. No trip signal is
issued.
b.
The control is programmed for at least one opera-
tion on TCC1.
•
Sequence Coordination will not advance the control
for those operations programmed for TCC2.
•
The Sequence Coordination feature operates for
both phase and ground faults; however, its program
of advancing the sequence position is controlled only
by the setting of Phase TCC1. If the control is pro-
grammed for all operations on TCC1, the sequence
coordination feature is not operative on the last oper-
ation. The feature will not advance the control if
advancing produces lockout.
•
If non-reclosing is activated, the Sequence Coordi-
nation feature is disabled.

dent of any reclosing.
