Publication 280E-QS001B-EN-P – February 2011
Troubleshooting Introduction
The purpose of this section is to assist in troubleshooting the ArmorStart®
Distributed Motor Controller using the LED Status Display and diagnostic
parameters.
13 No EEprom
(PF Drive Code
Reference 100) The checksum read from the board does not
match the checksum calculated. Set Parameter 141 (Reset to Defaults) to
Option 1 “Reset Defaults”.
14 No Hdw Flt (PF Drive Codes
Reference 70 and 122) Failure has been detected in the drive power
section or drive control and I/O section. 1. Cycle power.
2. Replace drive if fault cannot be cleared.
15 Drive
Controlled
Restart Retries (PF
Drive Code Reference
33) Drive unsuccessfully attempted to reset a fault
and resume running for the programmed number
of Parameter 192 (Auto Rstrt Tries). Correct the cause of the fault and manually
clear.
16 Drive
Controlled
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. Check for blocked or dirty heat sink fins. Verify
that ambient temperature has not exceeded
40°C (104°F).
1. Clear the fault or cycle power to the drive.
2. Program the drive parameters as needed.

ATTENTION: Servicing energized industrial control equipment can be
hazardous. Electrical shock, burns or unintentional actuation of controlled
industrial equipment may cause death or serious injury. For safety of
maintenance personnel as well as others who might be exposed to
electrical hazards associated with maintenance activities, follow the local
safety related work practices (for example, the NFPA70E, Part II in the
United States). Maintenance personnel must be trained in the safety
practices, procedures, and requirements that pertain to their respective
job assignments.
ATTENTION: Do not attempt to defeat or override fault circuits. The
cause of the fault indication must be determined and corrected before
attempting operation. Failure to correct a control system of mechanical
malfunction may result in personal injury and /or equipment damage due
to uncontrolled machine system operation.
ATTENTION: The drive contains high voltage capacitors that take time to
discharge after removal of mains supply. Before working on drive, ensure
isolation of mains supply from line inputs (R, S, T, [L1, L2, L3]). Wait three
minutes for capacitors to discharge to safe voltage levels. Failure to do so
may result in personal injury or death.
Darkened display LEDs is not an indication that capacitors have
discharged to safe voltage levels.
