Front Panel Features
1. REDUNDANT MODE LED
Single color LED (Yellow) indicates that the
PCU 2100 is operating in Redundant Mode. If the unit is operating in Dual
Mode, this LED will not be illuminated.
2. ACTIVE LED
Single-color blue LED indicates the presence of primary
power for the supply bank. When the LED is illuminated, the supply bank
is ON.
3. DC STATUS LED
Single-color (Green) LEDs display status for each
supply voltage. There is a bi-polar supply and a single-ended supply in
each bank, with an LED for each leg. Green illumination indicates normal
operating condition. Absence of illumination indicates a loss of voltage on
the corresponding leg.
4. FAULT LED
Single color red LED indicates Fault status. This Fault LED
will illuminate when a primary power supply fault has occurred, or there is
a load short. This LED is activated by the internal fault relay. Under nor-
mal operation, the LED is not illuminated.

Dual-color (Red/Green) LED
indicates the status of each bi-polar output group. Under normal opera-
tion, the LED will illuminate green. Under a fault condition, the LED will be
red. NOTE: This fault condition is monitored in parallel with the master
fault circuit, see number 4, above.
