TROUBLESHOOTING
Observe all Safety Guidelines detailed throughout this manual
INPUT CONTROL BOARD
Indication
Input current limit has been exceeded. Typically indicates short
term power overload. If problem persists contact Service
Department.
+15 VDC supply on Input control board too low. Verify input voltage
is within the acceptable range. If problem persists contact service
department.
Thermostat on primary module tripped. Typically caused by bottom
fan not working.
Problem with start-up sequence. If problem persists contact Service
Department.
Transformer current too high. Typically indicates short term power
overload. If problem persists contact service department.
Contact the Service Department.
WIRE DRIVE MODULE
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).
Absolute maximum motor current level has been exceeded. This is
a short term average to protect drive circuitry.
The Shutdown inputs on the Power Wave R350 have been dis-
abled. The presence of these errors indicates the Feed Head
Control PCB may contain the wrong operating software.
