Locate the regulator on outfeed of saw near the bottom of the outside of the saw cabinet and check the pressure. Adjust the regulator. Defective air cylinder Listen for air escaping from the cylinder. Check for free motion by disconnecting the air and manually move the system connected to that particular air cylinder. Replace air cylinder. Trouble moving the system indicated mechanical blockage. Remove the mechanical blockage and repeat the check. Air leak Listen for air leaks inside and outside the saw cabinet. Repair any air leaks immediately as they will cause the saw to drop below the required operating pressures. Defective solenoid valve Listen for leaks as the solenoid valve actuates. A leaking valve could indicate damage to the seals. Replace solenoid valve. Mechanical binding Disconnect the air and manually move axis in question. If difficult movement is experienced a bearing may be near the end of its life, call Alpine Equipment Customer Service for further assistance. 6.13 Blade Motor will not Start Breaker tripped Check CB 202 breaker in the main electrical cabinet. Reset breaker if tripped. Servo drive error Check codes on the blade motor servo drive in the electrical cabinet. It should display "bb" or "run." Locate the blade reset button on the inside of the main electrical cabinet. Hold this reset button for 10-15 seconds. This will reset the blade motor servo drive and clear the fault code. After resetting, if the drive does not display "bb" or "run" call Alpine Equipment Customer Service. Damaged power or feedback cables Visually inspect power and feedback cables. Replace damaged cables. Call Alpine Equipment Customer Service if further assistance is required. 6.14 Machine Stops during Cutting Operation Axis is blocked Visually inspect A1, T1, Z1, B1 (if equipped) for blockage. Remove blockage and restart homing process. Low Air pressure (Air pressure should read between 80-90 psi.) Locate the regulator on outfeed of saw near the bottom of the outside of the saw cabinet and check the pressure. Adjust the regulator. Cut out of range Setup the piece in semi-auto mode and run the cut. If the cut cannot be completed in semi-auto call Alpine Equipment Customer Service for assistance.
