Troubleshooting the FlexPak 3000 Drive 13-3
F00005 SUSTAINED OVERLOAD Inverse time overload circuit trip.
Possible causes:
• Incorrect armature current feedback scaling ( MOTOR RATED ARM AMPS ,
MAXIMUM CURRENT , CT TURNS RATIO , and/or J18 not set properly).
• Blown field supply fuse(s).
• Mechanical binding preventing the motor shaft from rotating freely.
F00006 BLOWER MOTOR
STARTER OPEN
The blower motor starter is open. If a blower motor starter kit is not
installed, connector P8 must be fitted with the proper substitute connector
to inhibit this fault.
Possible causes:
• Blown blower motor starter fuse(s).
• Disconnected, loosely connected, or damaged blower motor starter
wiring.
• Blower motor overload.
F00007 OPEN ARMATURE The motor armature circuit is open.
Possible causes:
• Motor armature winding not connected or open circuit.
• Blown inverting fault (DC) fuse.
• Inverting fault breaker tripped.
F00008 MOTOR THERMOSTAT
TRIP
Motor thermostat indicates high temperature. If a motor thermostat is not
used, customer terminal board pins 13 and 14 must be jumpered to inhibit
this fault.
Possible causes:
• Damaged or disconnected motor thermostat wiring.
• Inadequate ventilation.
• Blower motor failure.
• Incorrect blower rotation.
• Blocked ventilation slots.
• Clogged filters.
• Excessive armature current.
• One or more thyristors not operating.
