Pattern

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.

7I/O Fault

This error indicates a shorted sensor, shorted input device, or wiring input mistakes. If this fault occurs, the

offending problem should be isolated or removed prior to restarting the system. This fault can be disabled

and is disabled by default.

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 DNet Power Loss

DeviceNet power has been lost or has dropped below the 12V threshold. Check the state of the network

power supply and look for DeviceNet media problems. This fault can be disabled and is disabled by default.

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 Armor Start may need to be replaced. (Hdw Flt is the factory-enabled default

setting.) This fault cannot be disabled.
