POWER WAVE R450
Error Code #
331 Instantaneous Input Current Limit
334 Startup Current Check Failure
335 Startup Voltage Check Failure
336 Thermal Fault
337 Precharge Timeout
338 Input Power Limit
341 Input Voltage Dropout
346 Transformer Primary Overcurrent
347 Average Input Current Limit
349 Bus Undervoltage
Persistent errors require power to be cycled for the error to clear.
Temporary faults will go away on their own if the error condition is removed.
Error Code #
81 Motor Overload
82 Motor Overcurrent
83 Shutdown #1 Is Open
84 Shutdown #2 Is Open
If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, contact your
Lincoln Authorized Service Facility for technical troubleshooting assistance before you proceed.

Observe all Safety Guidelines detailed throughout this manual
INPUT CONTROL BOARD
Instantaneous input current limit has been exceeded. Typically indicates short
term power overload. If problem persists contact Service Department.
Input current limit was exceeded during machine power-up. If problem per-
sists contact Service Department.
Input voltage was too high or too low during machine power-up. Verify that
the input voltage is between 200V and 650V.
Thermostat on primary module tripped. Typically caused by a fan malfunction
or blocked air vent.
The DC bus voltage was not charged to a certain level at end of precharge. If
problem persists contact Service Department.
The input power drawn by the machine exceeded a safe level. If problem per-
sists, contact the Service Department.
The input voltage momentarily dropped out. Check connections and verify
quality of input power.
Transformer current too high. Typically indicates short-term power overload. If
problem persists, contact the Serivce Department.
Average input current limit has been exceeded. Typically indicates short term
power overload. If problem persists contact Service Department.
The DC bus voltage dropped below the allowable limit. If problem persists,
contact the Service Department.
WIRE DRIVE MODULE
Long term average motor current limit has been exceeded. Typically indicates
mechanical overload of system. If problem continues consider higher torque gear
ratio (lower speed range).
Absolute maximum motor current level has been exceeded. This is a short term
average to protect drive circuitry.
1.This refers to the 'green' I/O connector on the bottom of the controller.
If not being externally accessed, verify the integrity of the connector and jumper.
If accessed through a remote circuit, verify the integrity of that circuit.
