Error
Number
Error Message
208
ATC limit switch failure. Both ATC IN and OUT limit switches are active. Check that both
ATC limit switches are functioning properly. If ATC was mid tool change when this error
occurs, then use service code 513 to reset the ATC.
218
The ATC timed out moving OUT to the stored location. Check the air pressure and the
ATC limit switches. If ATC was mid tool change when this error occurs, then use service
code 513 to reset the ATC.

Diagnostics Table
There are two types of motion we discuss regarding the automatic tool changer, the inward and outward
motion of the tool changer sliding assembly, and the rotational movement of the tooling carousel. The
following table will attempt to simplify problem diagnosis:
Symptom
Possible Cause
Remedy
ATC will not
advance towards
the spindle.
•
The front sliding door is open
•
Compressed air is not being
supplied to the machine.
•
The in-line air switch is in the
closed position
•
Low air pressure
•
The solenoid is not receiving an
electrical signal. Is the solenoid
LED illuminated?
•
The blue polyurethane tube
supplying air to advance the sliding
mechanism toward the spindle
became pinched or obstructed.
•
An obstruction is preventing
movement.
•
Close the door or defeat the
safety interlock limit switch.
•
Supply 90 psi air to the machine
•
Make certain the in-line air switch
is in the open position (upward)
please refer to pneumatic
assembly drawing 26930 found at
the rear of this manual.
•
Find the cause of the low air
pressure. Pressure should be 90
psi at the
machine’s
regulator.
•
Check that the solenoid has not
been manually over ridden.
•
Replace and re-route pinched
tubing.
•
Remove the obstruction
ATC will not retract
away from the
spindle
Automatic Draw Bar has failed to
release the tool from the spindle
Re-set the air gap between the
automatic draw bar actuator, and the
automatic draw bar (5mm)
The ATC is
commanded “In”,
however, the ATC
advances towards
the spindle, pauses
then retracts on its
own.
•
The ATC “IN” limit switch is not
being recognized.
•
Air pressure is too low
•
Low air pressure sensor is not set
or functioning properly
•
The ATC “IN” limit switch is not
functioning properly
•
Remove the obstruction that is
preventing the ATC from reaching
the limit switch
•
Check the system air pressure at
the regulator, it should read 90 psi
•
Check the Low air pressure
sensor, it is set at the factory to
trigger at 60 psi
•
Replace the ATC “IN” limit switch
