LED INDICATORS
DS101 TRIP 1 - Front-panel indicator; lights when the TRIP 1 relay contacts are carrying trip cur-
rents of at least 0.2 amperes. This indicator is latched in non-volatile memory, and can only
be reset by pressing RESET switch SW302 on the display controller board.
DS102 TRIP 2 - Front-panel indicator; lights when the TRIP 2 relay contacts are carrying trip cur-
rents of at least 0.2 amperes. This indicator is latched in non-volatile memory, and can only
be reset by pressing RESET switch SW302 on the display controller board.
DS103 LOR 1 - Front-panel indicator; lights when the LOR 1 dc trip circuit carries currents of at
least 0.2 amperes. This indicator is latched in non-volatile memory, and can only be reset
by pressing RESET switch SW302 on the display controller board.
DS104 LOR 2 - Front-panel indicator; lights when the LOR 2 dc trip circuit carries currents of at
least 0.2 amperes. This indicator is latched in non-volatile memory, and can only be reset
by pressing RESET switch SW302 on the display controller board.
