FadalMaintenance Manual• Spindle must be off (Drawbar Interlock relay energized; this passes120V power to Drawbar SSR and floats Drawbar enable to AND gate).• Drawbar SSR must be energized.For Tool Up or Tool Down solenoid to be energized:• Board must have 120V power (see above).• SSR for Tool Up or Tool Down must be energized.• Logic on the 1330 will disable Arm Up if Arm down is on and vice versa.For Turret Fwd or Turret Rev to be active (turret in motion):• Board must have 120V power (see above).• Board must have 3-phase power (see above).(Spindle may be one. Turret motion with the spindle on is allowable but not armmotion.)• Overcurrent latch must be reset by microcontroller.• Turret Fwd or Turret Rev (not both) must be active (low).For Arm Fwd or Arm Rev to be active (arm in motion):• Board must have 120V power (see above).• Board must have 3-phase power (see above).• Spindle must be off (Drawbar Interlock relay energized; this pulls armenable to OR gates low).• Z-axis must be at tool change position (LED D20). If head is not at toolchange position, K9 will not be energized which will disable K8. (If thereis no head position sensor (J11) then J11 pins 2 and 3 must be jumpered.Shunt ELE-0088 is recommended for this.)• If CE machine, 120V output from 2000 or 1310 board must go to J6 pin7 (doors must be closed);• If not CE, J6 pin 7 must be jumpered to J6 pin 3. (CNC should not allowarm movement with doors open).If all the above is true the Arm Power relay will be energized.Overcurrent latch must be reset by microcontroller.Arm Fwd or Arm Rev (not both) must be active (low).176 Section 05: Automatic Tool Changers March 2003
