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.

Table 8 Network LED Status Indication
Fault Definitions Some of the Bulletin 284G ArmorStart Distributed Motor Controller faults
are detected by the internal hardware of the ArmorStart, while others are
detected by the internal drive. For internal drive faults, the internal hardware
of the ArmorStart simply polls the drive for the existence of faults and
reports the fault state. No fault latching is done by the internal hardware of
the ArmorStart for these faults. The Pr FltReset Mode parameter
(Parameter 23) determines the Auto Resettability of only the faults that are
detected on the main control board. These faults are listed as “param 23”
autoresettable in Table 9. The Auto Resettability of the faults that are
detected in the internal drive is controlled by internal drive parameters.
These faults are listed as drive controlled in Table 9.
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 are 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.
