4.4 Ready Check
The system undergoes a Ready Check operation at every startup, the end of every weld,
and at the exit of Setup mode. This procedure checks the height encoder position. If an
incorrect height value is returned, an alarm occurs.
Some of the possible causes of a Ready Check alarm are:
• The horn is stuck in the closed position
• Maintenance has moved the height encoder to an out of limit condition
• Defective encoder or electronics
• Encoder not plugged in to its connector
