Tool Changer Sensors
The automatic tool changer as a system has seven limit switches and/or sensors that monitor its state:
•
ATC Home Position Sensor (proximity switch)
•
ATC Count Sensor (proximity switch)
•
ATC Tool Detect Sensor (optical)
•
ATC “In” (limit switch)
•
ATC “Out” (limit switch)
•
Tool “Unclamp” (limit switch) Found on milling head
•
Tool “Clamp” (limit switch) Found on milling head

ATC Home Position Sensor
Is used to tell the control where home is location as shown in figure 4.4.1. During the Homing sequence,
the carousel will continue to index in the clockwise direction until the home position stud is detected. If
for some reason the stud is not detected, the ATC will simply “time out”. At which point it must be
determined whether or not the sensor is functioning or not.
At the pendent, index the tool changer until it is in the home position. Run service code F to determine
whether or not the sensor is detecting the home position stud.
If it is determined that the stud is not being detected, press the E-Stop and place a steel object, such as
a screw driver beneath the sensor and see if the amber LED illuminates. If not, the sensor is either not
receiving power, is faulty or the home position stud is not properly set.
