4.3
System Recovery
When a system error or alarm occurs, you must clear the error or alarm to return the system to normal operation. The paragraphs below describe the different types of alarms and errors you might encounter and how to remedy them when you do.
4.3.1
Alarms and Errors
There are three levels of alarms and errors that will stop the program:
• Error messages
• Minor alarms
• Major alarms
For more detailed information on alarm and error recovery, refer to the maintenance and DX100 controller documentation that is included with your Modular FabWorld
®
system (refer to Section 1.3).
4.3.1.1
Error Messages
Error messages are usually the result of simple, easily cleared operation errors. One example of this type of error is pressing the START button when the robots are not in PLAY mode.
Clear errors of this type by pressing the CANCEL button on the
Programming Pendant.
4.3.1.2
Minor Alarms
Minor alarms usually involve programming errors. Clear alarms of this type by pressing the CANCEL button on the Programming Pendant.

Major Alarms
Major alarms usually involve hardware failures. Examples of this type of error include an overload condition and abnormal speed.
Clear alarms of this type by cycling the DX100 controller in accordance with the following steps:
1. Rotate the DX100 controller’s power ON-OFF switch to OFF.
2. Allow the controller’s power ON-OFF switch to remain in the OFF position for approximately 10 seconds.
3. Rotate the controller’s power ON-OFF switch to ON.
4.3.2
E-STOP Recovery
An E-STOP (emergency stop) will occur under any of the following conditions:
• An E-STOP button is pushed in (activated).
• The work-cell access door is opened while the robots are not in
TEACH mode.
• The safety light curtain system is triggered while the positioner is sweeping.
• A welding torch collision triggers a shock sensor output (refer to
Section 4.3.3).
After an E-STOP condition occurs, restart the Modular FabWorld
®
system as follows:
1. To clear the E-STOP condition, perform any of the following actions that apply:
• Release the activated E-STOP push button
• Close the work-cell access door
• Clear the area in front of the positioner that is protected by the safety light curtain system
• Clear the shock sensor condition (refer to Section 4.3.3).
CAUTION
If an E-STOP condition occurs while the positioner is sweeping, the positioner will continue the sweep when the Modular FabWorld
® system is restarted.
2. Press the SERVO ON button on the Programming Pendant.
3. Select REMOTE mode on the Programming Pendant’s Mode Select
Switch to transfer control of the system to the Operator Station.
4. Press the green START button on the Operator Station.
The Modular FabWorld
®
system is now ready to continue operation.
