Figure 1, Figure 2 , and Figure 3 show the location and designation of the NCE25, NAE35, NAE45, and NAE55 LEDs that indicate the status of the engines. Some models do not have all the LEDs shown in these figures. Table 1 describes their Normal Status and Function.

LED Label (Color)

NAE Series

Normal Status

Descriptions/Other Conditions

POWER (Green)

NCE25, NAE35, NAE45, NAE55

On Steady

On Steady = Unit is getting power from either the battery or 24 VAC power. Also see the 24 VAC LED. Off Steady = Unit is shut down.

ETHERNET (Green)

NCE25, NAE35, NAE45, NAE55

Flicker

Flicker = Data is transferring on the Ethernet connection. Ethernet traffic is general traffic (may not be for the NAE).

Off Steady = No Ethernet traffic, probably indicates a dead Ethernet network or bad Ethernet connection.

10/LINK (Green)

NCE25, NAE35, NAE45, NAE55

On Steady

On Steady = Ethernet connection is established at 10 Mb/s.

100/LINK (Green)

 

On Steady

On Steady = Ethernet connection is established at 100 Mb/s

100/1000 Link (Green/Yellow)

 

On Steady

On Steady (Green) = Ethernet connection is established at 100 Mb/s.

On Steady (Yellow) = Ethernet connection is established at 1,000 Mb/s.

FCA (Green)

 

Flicker

On Steady = Controllers are defined to FC A (Trunk 1) in the NAE55, but none are communicating. (NAE55 transmitting only)

Flicker = Normal communications; FC A port is transmitting and receiving data. Flickers are generally in sync with data transmission but should not be used to indicate specific transmission times. Also, the flicker rate for the MS/TP bus is different from the rate for the N2 Bus.

Off Steady = No controllers are defined to FC A (FC Bus 1 or N2 Trunk 1) in the NAE55.

FCB (Green)

NAE55

Flicker

On Steady = Controllers are defined to FC B (Trunk 2) in the NAE55, but none are communicating. (NAE55 transmitting only)

Flicker = Normal communications; FC B port is transmitting and receiving data. Flickers are generally in sync with data transmission but should not be used to indicate specific transmission times. Also, the flicker rate for the MS/TP bus is different from the rate for the N2 Bus.CR83936

Off Steady = No controllers are defined to FC B (FC Bus 2 or N2 Trunk 2) in the NAE55.

FC BUS or LON 1

NCE25, NAE35, NAE45

 

Flicker = N2 controllers are defined to FC BUS in the NAE35/45, but none are communicating. (NAE35/45 transmitting only)

Fast Flicker (may appear Steady on) = Normal communications; FC BUS port is transmitting and receiving data. Flickers are generally in sync with data transmission but do not indicate specific transmission times.

Off Steady = No field controllers are defined to FC BUS in the NAE35/45.

SA BUS (Green)

NCE25

Blinking

Blinking - 5 Hz = Data Transmission (normal communication) Off Steady = No Data Transmission On Steady = Communication lost, waiting to join communication ring

PEER COMM (Green)

NCE25, NAE35, NAE45, NAE55

Varies (see next column)

Flicker = Data traffic between NAE devices. For an NAE that is not a Site Director, this LED indicates regular heartbeat communications with the Site Director. For a Site Director NAE, flashes are more frequent and indicate heartbeat communications from all other NAE devices on the site. For a single NAE on a network without an ADS/ADX, there is no flicker.

RUN (Green)

NCE25, NAE35, NAE45, NAE55

On Steady

On Steady = NAE software is running.

On 1 second, Off 1 second = NAE software is in startup mode.

On 0.5 seconds, Off 0.5 seconds = NAE software is shutting down.

Off Steady = Operating system is shutting down or software is not running.

24 VAC (Green)

NAE55

On Steady

On Steady = 24 VAC power present

Off Steady = Loss of 24 VAC power. In the Off Steady condition, the NAE may be running on battery power. Also see the POWER LED.

MODEM RX

NCE25, NAE35, NAE45

Flicker

Flicker indicates modem is connected and receiving data.

MODEM TX2

NCE25, NAE35, NAE45

Flicker

Flicker indicates modem is connected and transmitting data.

BATT FAULT (Red)

NCE25, NAE35, NAE45, NAE55

Off Steady

Off Steady = Normal operation.

On Steady = Battery fault. Replace the battery. Battery not connected or cannot be charged. The BATT FAULT LED may remain On for up to 24 hours after initially powering on the NAE. If the BATT FAULT LED remains on longer than 48 hours after initially powering on the NAE, check the battery connection or replace the battery.

GENL FAULT or FAULT (Red)

NCE25, NAE35, NAE45, NAE55

Off Steady

Off Steady = Normal operation.

On Steady = General Fault. Fault conditions are user configured in software. Pre-configured fault conditions include excessive CPU use, flash or memory use, excessive CPU or PWB temperature, or battery fault. In normal operation, the GENL FAULT LED stays on steady for the first half of the startup sequence.

Blink - 2 Hz = Download or Startup in progress, not ready for normal operation.

Blink Rapidly - 5 Hz = One or more defined SA Bus devices are offline. Check SA Bus devices for problems, including low batteries on wireless sensor.

Note: On NCE25 and NAE35/45 models, the GENL FAULT LED label designation is FAULT.
1 LED labeled FC BUS on models that support MS/TP Bus or N2 Bus, and labeled LON on models that support LonWorks network.
2 Modem LEDs are only on NCE25 models with internal modems. Modem functionality not supported at Release 9.0.7 or later.
