    BKCOM,

    I dont know the password, but if you send the ladder program to me, its posible i broke the password.

    P.S. This alarm, maybe, inside the turret has 2 sensors. One that count in CW direction and another one in CCW direction. Maybe one this sensors are broken

    you may want to check the proximity switch SQ-9 for turret count A (Input Signal X1004.0) and proximity switch SQ-8 for turret count B (Input Signal X1004.1). Both switches situated at rear of turret face.

    Mori ladder password is usually "L".
    EX alarms are ladder generated, therefore machine sensor, therefore probably a faulty prox inside turret.
    You can check prox status in DIAG screen. Just use the electrical drawings to find the right input.
