Fault
Code
Failure Possible
Causes
2 DC Bus Under Voltage 1. Low AC line in.
2. Transformer feeding AC in on the MLD is
undersized for the load.
3 DC Bus Over Voltage 1. High AC line in.
2. Regen circuit is not operating correctly.
3. Regen resistor not connected correctly or has
failed.
4 IGBT Fault 1. Too much weight being lifted by the unit (applies if
weight limit set greater than 185 pounds on a 150
pound unit).
2. Loss of an internal power supply voltage.
3. PWM logic error.
4. Over current detected through IGBT.
5 IGBT Over Temperature 1. IGBT is greater than 85 degrees C.
6 Over Current 1. Over current detected through the current sensor.
2. Too much weight being lifted by the unit (applies if
weight limit set greater than 185 pounds on a 150
pound unit).
3. Wire Rope is bound.
4. The motor is wired incorrectly.
5. IGBT failure (applies if code will not reset with the
cycling of power).
7 Motor Over Temperature 1. Motor has exceeded its upper temperature limit.
8 Safety Relay Failure 1. Relay timing closing the motor brake and opening
the motor windings does not meet specified timing
requirements.
9 Unknown Source Reset 1. CPU was reset, but not by power down or via the
JTAG programming port.
10 Missing Clock Caused Reset 1. 16 Mhz clock stopped.
11 Watchdog Timer Caused Reset 1. The CPU has stopped running code feeding
watchdog timer.
12 XTAL Oscillator Startup Error 1. The external 16 Mhz oscillator did not start.
13 Unexpected Hardware Configuration 1. Mode switch does not match jumper or software
configuration.
2. Handle pulled in during power up.
3. Power interruption during operation.
