Quick Reference
Troubleshooting
There are four LEDs on the front of the ArmorStart that can provide an
indication as to the health of the device. The following is a brief explanation
of the operation of each LED.

LED Status Indication

Network LED Status Indication
LED
Definition
Power
This LED will be illuminated solid green when control power is present and
with the proper polarity.
Run
This LED will be illuminated solid green when a start command and control
power is present.
Network
This bi-color LED is used to indicate the status of the DeviceNet network. See
the Network Status LED table below for additional information.
Fault
This LED is used to indicate the fault status of the ArmorStart. When the unit is
faulted, the unit will respond with a specific blink pattern to identify the fault.
See the Fault LED table below for additional information.
Network Status LED
Definition
Possible Causes
Off
The device has not completed the initialization, is not on an
active network, or may not be powered up.
Check to make sure the product is properly wired and
configured on the network.
Flashes green-red-off
While waiting to detect the network baud rate, the LED will
flash this pattern about every 3 seconds.
If the product stays in this state it means that there is no set
baud rate. Insure that at least one device on the network
has a set baud rate.
Solid Green
The device is operating in a normal condition, and is
communicating to another device on the network.
No action required.
Flashing Green
The device is operating in a normal condition, is on-line, but
with no connection to another device. This is the typical
state for new devices.
The device may need to be mapped to a master scanner,
placed in a scanlist, or have another device communicate to
it.
Flashing Red
Recoverable fault has occurred.
Check to make sure the PLC and scanner are operating
correctly and that there are no media/cabling issues. Check
to see if other networked devices are in a similar state.
Solid Red
The device has detected a major error that has rendered it
incapable of communicating on the network (Duplicate
MAC ID, Bus-off, media issue).
Troubleshooting should be done to ensure that the network
is correct (terminators, lengths, etc.) and there is not a
duplicate node problem. If other devices on the network
appear to be operating fine and power cycling the device
does not work, contact Technical Support.
Flashing Red and Green
The device is in a communication faulted state.
Power cycling the device may resolve the problem;
however, if the problem continues, it may be necessary to
contact Technical Support.
