Troubleshooting 135
Flow Chart 0-20 E131 Error Code
E131
UNABLE TO CONTROL SHEAR WHILE HOMING
This error only occurs while the tyer is in its homing sequence. It indicates either of two similar conditions.
E132 indicates that the controller detected the shear’s home prox turning “ON”, but it cannot drive the
shear past the prox to turn the prox “OFF”. E133 indicates that the controller detected the shear’s home
prox turning “OFF”, but it cannot drive the shear 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 holder shear from moving as needed. With power turned
“OFF”, turn the holder shear motor thru its complete range of motion (MTR3)
≥ 360°, check for debris, is a jam present?
With power turned “ON” (do not press “RUN”), rotate holder shear past its prox, verify H/S
PH A, PH B and Home LEDs on FTB are turning both “ON” and “OFF”, are they working?
Check Aux board, then
MTR3, then CPU, replace
parts as necessary.
Troubleshoot prox
