14.3.1 Train Part Faults
There are two types of faults that can occur when training a part:
1. Train Part Timeout: A timeout fault that occurs when the user clicked the “Train
Part” button to request a PartCode, but the system did not respond within the 10
second timeout period.
Figure 113: Train Part Timeout Error
2. Train Part Failed: This fault occurs when the system returns a Negative
Acknowledge (NAK) when asked to read the PartCode. This means that the device
could not successfully read the PartCode.

Faulty Recovery
15.1 Recovering From Emergency Stop and Other
Machine Errors
If the Emergency Stop button is engaged or the machine encounters a system error,
perform the following procedure to return the machine back to normal operation.
Note: If the Emergency Stop was engaged because of system failure, DO NOT
disengage the Emergency Stop button. Shut the system down 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. Press the “Continue” button to return the head to the Standby Position. The
screen will return to the Cycle Stop mode.
Note: All functions are stopped until the “Emergency Stop” button is disengaged.
Figure 114: Emergency Stop Screens
4. Correct the fault that caused the operator to engage the “Emergency Stop” button.
5. Open the access door.
6. Remove all parts from the work area. Find any parts that can still be used and put
them in the input queue.
7. Close the access door.

8. Perform the Startup Procedure. Refer to Section 10.1 for more information.
If a door is open while the Door Bypass switch is in the OFF position, or the workcell is in
any machine state besides the Manual or Calibration modes, it will cause a door error.
Recovery from a door error is similar to the recovery from an Emergency Stop.
Other workcell errors can occur, such as:
• Low air pressure
• Low material flow
• Insufficient exhaust air flow
These errors must first be corrected, and then the Startup Procedure can be performed
to continue. Refer to the section that relates to the error. Refer to Section 10.1 for more
information on the Startup Procedure.
Below are examples of the other possible error screens:
