EXCEL 12 MODULES
1 LED remains OFF after power-up.
2 LED is ON continuously after first power-up.
LED flashes at power-up, goes OFF, then comes ON
3
solid.
4 LED flashes briefly once every second.
5 LED flashes ON and OFF at 0.5 Hz.
OFF duration ≈ 10 sec. Afterwards, the service LED
6a turns ON and remains ON, indicating completion of the
blanking process.
OFF duration ≈ 1 sec. Afterwards, the service LED turns
6b
ON and remains ON.
OFF duration is 1...15 sec, depending on the application
6c size and the system clock. Afterwards, the service LED
begins flashing ON and OFF at 0.5 Hz.
OFF duration is indefinite (1...15 sec to load internal
6d
EEPROM; remains OFF).
7 LED remains OFF after a short ON duration.
LED flashes ON for one second and OFF for one
8 second five times in succession and then remains OFF
for five seconds, after which the pattern is repeated.
LED flashes ON for one second and OFF for one
9 second four times in succession and then remains OFF
for five seconds, after which the pattern is repeated.

Service LED Behaviors and Meanings
Defective device hardware. Suspect power supply
problems, clock problems, or a defective Neuron Chip.
Defective hardware.
Node is applicationless.
This device is probably experiencing continuous
watchdog resets, or the external memory or EEPROM is
corrupt.
Node is unconfigured but has an application.
Using EEBLANK on a Neuron 3150 Chip-based custom
node.
First power-up with a new PROM on a Neuron 3150
Chip-based custom node. Application less firmware
state exported.
First power-up with a new PROM on a Neuron 3150
Chip-based custom node. Unconfigured firmware state
exported.
First power-up with a new PROM on a Neuron 3150
Chip-based custom node. Configured firmware state
exported.
Node is configured and running normally.
Module has received a WINK command from the
network. Other physical outputs are unaffected.
There are two possible causes:
1. Coprocessor identification. After reset (power-up),
the Neuron Chip waits for the coprocessor's ID
message (sent periodically until acknowledged).
While waiting, the application remains OFF. This wait
status will remain if the hardware ID fails e.g.
because the Neuron application does not match the
hardware.
2. NEC/Neuron communication failure. If a NEC failure
(e.g. NEC application too big, sensor break, etc.) is
detected, the service LED flashes as described at
left, and continues doing so as long as the NEC
failure is recognized.
