Fault 11 Detail Parameter 61 provides a more granular description of the faults that occur.
• An F11 protection fault indicates that the internal communication has
stopped
• There is a 10 second delay before an F11 Internal Comm. fault is present
• Common causes of an Internal Comm. fault:
– The local ArmorStart Disconnect switch is in the OFF position.
– 3-Phase line power feeding the ArmorStart is not connected or is
turned OFF.
– Switched Control Power is not connected or is turned OFF.
– Poor power quality (Brown Out)
• First things to check:
– Verify that the local disconnect is in the ON position.
– Verify that the unit has 3-Phase Line Voltage present and it is within
specified tolerances.
– Verify that the ArmorStart unit has Control Voltage present and it is
within specified tolerances.
– Attempt to clear the fault by pressing the local reset or sending the
ArmorStart a network reset.
– Cycle power to the ArmorStart unit and try to clear the fault again.
• If an Internal Comm. fault persists, refer to Parameter 61 – LastPR Fault
for additional details on the last protection fault. Refer to the following
table for troubleshooting information based on what Parameter 61 returns.
Also refer to Parameters 107…109 to get the VFD fault code that can be
referenced below.
14 No Hdw Flt (PF Drive Codes

Misc. Fault (PF Drive Code
Reference 2, 8, 29, 48 and
80) Heatsink temperature exceeds a predefined value. The
drive was commanded to write default values to EEprom.
The autotune function was either cancelled by the user or
failed. If DB1 option installed refer to P61 for additional
diagnostics. Check for blocked or dirty heat sink fins. Verify that
ambient temperature has not exceeded 40 °C (104 °F)
and mounted properly.
1. Clear the fault or cycle power to the drive.
2. Program the drive parameters as needed. Restart
