Troubleshooting 125
Flow Chart 0-10 E111 Error Code
E111
UNABLE TO CONTROL NEEDLE WHILE HOMING
This error only occurs while the tyer is in its homing sequence. It indicates either of two similar conditions. E112
indicates that the controller detected the needle's home prox turning “ON”, but it cannot drive the needle past the
prox to turn the prox “OFF”. E113 indicates that the controller detected the needle's home prox turning “OFF”, but
it cannot drive the needle back over the prox to turn the prox “ON”.
SAFETY WARNING:
The following troubleshooting procedure may require that tests be made with the electrical
enclosures open and power turned “ON”. These tests should only be conducted by authorized
personnel who are aware of the electrical and mechanical hazards present.
Clear jam.
The most likely reason for this error is a mechanical obstruction or
jam which is preventing the needle from moving as needed. With
power turned “OFF”, turn the needle motor thru its complete range of
motion (MTR1) < 360°, check for debris, is a jam present?
With power turned “ON” (do not press “RUN”), rotate needle past its prox, verify needle PH
A, PH B and Home LEDs on FTB are turning both “ON” and “OFF”, are they working?
Check Aux board, then
MTR1, then CPU, replace
parts as necessary.
