E112-113
ONLY ONE EDGE OF NEEDLE'S HOME PROX IS DETECTED
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?
Initiate another homing sequence, does the motor move
in both directions while searching for home prox?
Does prox light turn “ON”
and “OFF” when activated
by hand?
Does prox LED on FTB
turn “ON” and “OFF” when
activated by hand?
