Error Code #

Indication

 

 

 

 

 

 

 

 

 

 

331

Peak input current limit

Input current limit has been exceeded. Typically indicates short

 

 

 

 

term power overload. If problem persists contact Service

 

 

 

 

Department.

 

 

 

 

 

 

 

 

 

 

333

Under-voltage lockout

+15 VDC supply on Input control board too low. Verify input voltage

 

 

 

 

is within the acceptable range. If problem persists contact service

 

 

 

 

department.

 

 

 

 

 

 

 

 

 

 

336

Thermal Fault

Thermostat on primary module tripped. Typically caused by bottom

 

 

 

 

fan not working.

 

 

 

 

 

 

 

 

 

 

337

Pre-charge timeout

Problem with start-up sequence. If problem persists contact Service

 

 

 

 

Department.

 

 

 

 

 

 

 

 

 

346

Transformer primary over current

Transformer current too high. Typically indicates short term power

 

 

 

 

overload. If problem persists contact service department.

 

 

 

 

 

 

 

 

 

 

 

Other

 

Contact the Service Department.

 

 

 

 

 

 

 

 

 

 

 

 

WIRE DRIVE MODULE

 

 

 

 

 

Error Code #

 

Indication

 

 

 

 

81

Motor Overload

 

Long term average motor current limit has been exceeded.

 

 

 

Typically indicates mechanical overload of system. If problem con-

 

 

 

tinues consider higher torque gear ratio (lower speed range).

 

 

 

 

82

Motor Overcurrent

 

Absolute maximum motor current level has been exceeded. This is

 

 

 

a short term average to protect drive circuitry.

 

 

 

 

83

Shutdown #1

 

The Shutdown inputs on the Power Wave R350 have been dis-

 

 

 

abled. The presence of these errors indicates the Feed Head

 

 

 

84

Shutdown #2

 

Control PCB may contain the wrong operating software.

 

 

 

 

CAUTION

If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, contact your Local Lincoln Authorized Field Service Facility for technical troubleshooting assistance before you proceed.
