LED indicators are provided for AC OK (green), inputs active (red), system fault (yellow), ground fault (yellow),
and NAC 1-4 troubles (yellow).
Refer to
Figure 1
on page 5 for the location of each LED on the board. Refer to

The FPP-RNAC-8A-4C has a TROUBLE RESET momentary switch to clear latched trouble
conditions. The TROUBLE1 - 4 LEDs (refer to
These trouble LEDs indicate open or shorted outputs and a low or missing battery. A trouble
condition registers if the AC main voltage goes below the stated threshold. The output of the power
supply is monitored for excessive output voltage, ground fault, and so on.

Description
Red
Input Active – This corresponds to active INPUT commanding outputs to turn on.
This active input signal can come from either on-board input (or from both
inputs), or can be controlled by an option bus command.
Alternate function:
Reprogramming operation: The LED should be off.
Reprogramming complete: The LED blinks the number of the software
revision when the programming process completes successfully.
The green LED lights to indicate that the user can now read the value. A series
of blinks indicates the primary revision number, followed by the secondary
revision number. The green LED turns off to indicate the end of the sequence.
The display continues until the Flash module is removed from the programming
port. For example, revision number 2.04 has two blinks followed by a pause
and then four blinks.
Revision number display:
and held longer than 2 sec, the revision number shows. (Refer to
Reprogramming complete, above.)
Green
AC input is OK; the power supply is operating from the AC line.
When LED 2 extinguishes, the AC fault relay activates after a programmed delay.
Alternate function:
Reprogramming operation: This LED should blink during the operation
Reprogramming complete: This LED remains on through one sequence of
indicating the revision number. After showing the revision number, the LED
turns off briefly and then turns on again to indicate that counting the revision
should start again.
Reprogramming failed: This LED continues to blink at a constant rate
whenever the Flash module is connected to the Programming port. The
programming process typically takes less than 20 sec. If this LED blinks for
longer than 30 sec, a problem exists.
Revision number display:
and held longer than 2 sec, the red LED shows the revision number. (Refer to
Reprogramming complete in the description of the red LED in this table, above.)
