Abstract

An abrasive belt machine including a support housing having a pivoting arm that supports an abrasive belt rotatably coupled to a drive motor; a safety controller operatively coupled with the drive motor; an E-stop operatively coupled to the safety controller; a foot pedal switch operatively coupled to the drive motor; and a 480 volt alternating current 3 phase electrical power supply electrically coupled to the drive motor.

What is claimed is: 
     
         1 . An abrasive belt machine comprising:
 a support housing having a pivoting arm that supports an abrasive belt rotatably coupled to a drive motor;   a safety controller operatively coupled with the drive motor;   an E-stop operatively coupled to the safety controller;   a foot pedal switch operatively coupled to the drive motor; and   a 480 volt alternating current 3 phase electrical power supply electrically coupled to the drive motor.   
     
     
         2 . The abrasive belt machine according to  claim 1 , wherein the safety controller is electronically coupled to the E-stop, a guard door sensor, a vacuum pressure/air flow sensor and the like. 
     
     
         3 . The abrasive belt machine according to  claim 1 , wherein the safety controller is configured to prevent operation of the drive motor responsive to predetermined conditions. 
     
     
         4 . An abrasive belt machine comprising:
 a support housing having a pivoting arm that supports an abrasive belt rotatably coupled to a drive motor;   a guard door coupled to the support housing proximate the abrasive belt, the guard door including a guard door sensor;   an exhaust vacuum coupled to the support housing proximate the abrasive belt, the exhaust vacuum including a vacuum/air flow sensor;   a safety controller operatively coupled with the drive motor;   an E-stop operatively coupled to the safety controller;   a foot pedal switch operatively coupled to the drive motor; and   a 480 volt alternating current 3 phase electrical power supply electrically coupled to the drive motor.   
     
     
         5 . The abrasive belt machine according to  claim 4 , wherein the safety controller is electronically coupled to the E-stop, the guard door sensor, the vacuum pressure/air flow sensor and the like. 
     
     
         6 . The abrasive belt machine according to  claim 4 , wherein the safety controller is configured to detect electrical faults, short circuits, welded contacts and the like. 
     
     
         7 . The abrasive belt machine according to  claim 4 , further comprising:
 a fault light on a panel, wherein the safety controller is configured to provide a signal to the fault light on the panel.   
     
     
         8 . A process for configuring an abrasive belt machine for safety comprising:
 a support housing having a pivoting arm that supports an abrasive belt rotatably coupled to a drive motor;   coupling a guard door to the support housing proximate the abrasive belt, the guard door including a guard door sensor;   coupling an exhaust vacuum to the support housing proximate the abrasive belt, the exhaust vacuum including a vacuum/air flow sensor;   coupling a safety controller with the drive motor;   coupling an E-stop to the safety controller;   coupling a foot pedal switch to the drive motor; and   supplying a 480 volt alternating current 3 phase electrical power supply to the drive motor.   
     
     
         9 . The process of  claim 8 , further comprising:
 electronically coupling the safety controller to the E-stop, a guard door sensor, a vacuum pressure/air flow sensor and the like.   
     
     
         10 . The process of  claim 8 , further comprising:
 configuring the safety controller to prevent operation of the drive motor responsive to predetermined conditions.
