24.2.1 LED INDICATORS (See note on page 24-7)
All LEDs are latched targets except DS10, DS11 and DS12. All targets are cleared by pressing the RESET but-
ton on the Display Controller. Terminal block connections for TB1, TB2 and TB3 can be seen in Figures 24-3 &
24-7.
DS10 When “THREE POLE” LED is lit, indicates that all three phases will trip simultaneously if a trip is
commanded.
DS11 When “SINGLE POLE” LED is lit, indicates that if a trip is commanded, only the phase com-
manded to trip, will trip.
DS12 When “TRIP DISABLE” LED is lit, indicates that the single pole chassis (lower chassis) has not
been initialized and all trips are blocked.
DS3 When “PHASE A TRIP” LED is lit, indicates circuit closure between TB1A-1 and TB1A-2, TB1A-3
and TB1A-4, TB1A-5 and TB1A-6, TB1B-1 and TB1B-2, TB1B-3 and TB1B-4, TB1B-5 and TB1B-
6.
DS1 When “PHASE A TC1” LED is lit, indicates circuit closure between TB1B-1 and TB1B-2 and
current flow has been sensed.
DS2 When “PHASE A TC2” LED is lit, indicates circuit closure between TB1B-3 and TB1B-4 and
current flow has been sensed.
DS6 When “PHASE B TRIP” LED is lit, indicates circuit closure between TB2A-1 and TB2A-2, TB2A-3
and TB2A-4, TB2A-5 and TB2A-6, TB2B-1 and TB2B-2, TB2B-3 and TB2B-4, TB2B-5 and TB2B-
6.
DS4 When “PHASE B TC1” LED is lit, indicates circuit closure between TB2B-1 and TB2B-2 and
current flow has been sensed.
DS5 When “PHASE B TC2” LED is lit, indicates circuit closure between TB2B-3 and TB2B-4 and
current flow has been sensed.
DS9 When “PHASE C TRIP” LED is lit, indicates circuit closure between TB3A-1 and TB3A-2, TB3A-3
and TB3A-4, TB3A-5 and TB3A-6, TB3B-1 and TB3B-2, TB3B-3 and TB3B-4, TB3B-5 and TB3B-
6.
DS7 When “PHASE C TC1” LED is lit, indicates circuit closure between TB3B-1 and TB3B-2 and
current flow has been sensed.
DS8 When “PHASE C TC2” LED is lit, indicates circuit closure between TB3B-3 and TB3B-4 and
current flow has been sensed.
