Front panel LED details:
• Number of LEDs: 17
• Programmability: Any FlexLogic operand
• Reset mode: self-reset or latched
The 869 front panel provides two columns of 7 LED indicators each, and 3 LED pushbutton
indicators. The "IN-SERVICE" (LED 1) and the "PICKUP" (LED 4) indicators from the first LED
column are non-programmable LEDs. The bottom 3 LED indicators from the first column,
and the 7 LED indicators from the second LED column are fully programmable. The
indicators "TRIP" (LED 2), and "ALARM" (LED 3), are also programmable, and can be
triggered by either a selection of FlexLogic operand assigned in their own menu, or by the
operation of any protection, control or monitoring element with function selected as Trip,
Alarm, or Latched Alarm.
The RESET key is used to reset any latched LED indicator or Target Message once the
condition has been cleared (latched conditions can also be reset via the RESETTING menu).

Some status indicators are common while some are feature specific which depend on the
availability in the order code. The common status indicators in the first column are
described below.
• IN SERVICE

ready to serve. This LED indicates that control power is applied, all monitored
inputs, outputs, and internal systems are OK, and that the device has been
programmed.
