16 Fault Recovery
16.1 Recovering From Emergency Stop and Other
Machine Errors
If the Emergency Stop button is engaged or the machine encounters a system error, do
this procedure to return the machine to normal operation.
WARNING! If the Emergency Stop was engaged because of system failure, DO
NOT disengage the Emergency Stop button. Shutdown the system and have
qualified personnel repair the machine.
Do not operate the workcell again until the cause of the failure has been repaired.
1. Open the front doors and remove all parts/PCBs from the work area.
2. Close the doors and disengage the “Emergency Stop” button if it was not
engaged because of a system failure.
3. Push “Continue”.
4. Press “Continue” to return the head to the standby position. The screen returns
to Cycle Stop.
NOTE: All functions are disengaged until the “Emergency Stop” button is
disengaged.
Figure 93: Emergency Stop
5. Correct the fault which caused the operator to engage the “Emergency Stop”
button.
6. Open the access door.
7. Remove all parts from the work area. Find the parts that can still be used and
put them in the input queue.

8. Close the access door.
9. Do the Startup Procedure.
If a door is open while the DOOR BYPASS switch is in the OFF position, or any machine
state besides manual mode or calibration, it will cause a door error. Recovery from a
door error is like the recovery from an Emergency Stop.
Other workcell errors can occur, such as: low air pressure, low material flow or
insufficient exhaust air flow. You must correct these errors first, and then do the startup
procedure to continue. Refer to the section that relates to your error.
