Power LED
State Description Corrective Actions
Green LED
Power is on and
CME-LW01 works
LED is OFF
Power on or program is
abnormal
1. Check if power is 24V or
plug is loose.
2. Check if flash memory IC is
well-inserted to the socket.
SP LED
State Description Corrective Actions
Green LED
It communicates to AC
drive
Blinked Green
LED
CME-LW01 reads default
setting from AC drive
Red LED Disconnect or time-out
1. Check if cable is loose.
2. Check if the communication
protocol is properly set.
Service LED
State Description Corrective Actions
LED blinks at
1/2 Hz rate
This is the normal
situation for an
un-configured device
LED is OFF Bad hardware device
Check if anything wrong with
power supply, clock or
Neuron chip.
LED is ON
continuously,
even when
power is first
applied to the
device.
Bad hardware device
1. Check if anything wrong
with power supply, clock or
Neuron chip.
2. Check if there is a short
circuit between pin 17 and
18.
LED blinks at
power-up,
goes OFF,
then ON
solid.
This is the normal
situation for an
application-less device.
If the device is not an
application-less, then it could
be memory problems or
application code errors. A
self-test failure can also turn
the LED ON solid.
