In these cases check the input AC voltage first and insure that the M-227 is set for

the correct input Voltage. Another possible reason for no display or scrambled

displays is RF interference. Although the M-227 is protected against this, certain

conditions are still possible to occur that can cause this

Outside RF from another type or source such as a HF welding machine or a radio

transmitter near by could cause a problem. If these conditions continue contact

the AMI service Dept. for possible solutions.

At Power On the weld schedule memory storage is checked for any type of

corruption. If any of the checks fail the system will display the following:

LIBRARY MEMORY ERROR RELOAD FROM EMM

PRESS PRINT FOR MEMORY STATUS REPORT

NOTE

When the print key is pressed any weld schedule with a directory or link

error will automatically be “DELETED”. Any schedule with a sum check

error will be flagged corrupted on the print out and the user should call

up that weld schedule and verify the parameter values.
