Switch
Section
Function
5
When ON (down), inhibits operation of the output relays unless the supervisory contacts
are closed.
6
When ON (down), the output relays are inhibited until both the T1 and T2 timers have
cycled. At this time, a sensed current above pickup will energize the output relay.
7
When ON (down), a BF output will occur after the expiration of Timer 1 if the supervisory
contact is closed, regardless of the presence or absence of sensing current.
8
When ON (down), requires closure of the supervisory contact, and completion of both T1
and T2 timing cycles to energize the BF output relays. In this case, sensed current need
not be present. However, if T1 times out before T2, and if sensing current is above pickup,
a BF output will occur.

NOTE
Switches seven and eight may be used for conducting system tests. Note that a
BFI output can be obtained WITHOUT the presence of line current.
