Definitions Possible Causes or Remedies
1
Short Circuit The motor circuit protector has tripped, or the internal wiring protection algorithm has detected an unsafe
current range. Try to reset the protector if tripped. If the condition continues, check the power wiring. This
fault cannot be disabled.
2
Overload trip The load has drawn excessive current and based on the trip class selected, the device has tripped. Verify
that the load is operating correctly and the ArmorStart is properly set-up. This fault cannot be disabled.
3
Phase Loss The ArmorStart has detected a missing phase. Verify that three-phase voltage is present at the line side
connections. This fault can be disabled and is disabled by default.
4 Reserved Not Used
5 Reserved Not Used
6
Control Power The ArmorStart has detected a loss of the control power voltage. Check control voltage, wiring, and proper
polarity. Also check and replace the control voltage fuse if necessary. This fault can be disabled and is
disabled by default.
7 I/O Fault This error indicates a blown output fuse.
8 Over Temperature This fault is generated when the operating temperature has been exceeded. This fault cannot be disabled.
9
Phase Imbalance The ArmorStart has detected a voltage imbalance. Check the power system and correct if necessary. This
fault can be disabled and is disabled by default.
10 Reserved Not Used
11 Reserved Not Used
12 Reserved Not Used
13
EEPROM Fault This is a major fault, which renders the ArmorStart inoperable. Possible causes of this fault are transients
induced during EEprom storage routines. If the fault was, initiated by a transient, power cycling should
clear the problem otherwise replacement of the ArmorStart may be required. This fault cannot be disabled.
14
Hardware Fault This fault indicates that a serious hardware problem exists. Check for a base/starter module mismatch. If
no mismatch exists, the ArmorStart may need to be replaced. (Hdw Flt is the factory-enabled default
setting.) This fault cannot be disabled.
