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 clear
them.
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
DX200 controller and MH24 robot documentation that is included with
your EcoTrim ET-1024 System (refer to section 1.3).
4.4.1.1 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 robot is not in PLAY mode.
Clear errors of this type by pressing the CANCEL button on the
Programming Pendant.
4.4.1.2 Minor Alarms
Minor alarms usually involve programming errors. Clear alarms of this
type by pressing the CANCEL button on the Programming Pendant.
4.4.1.3 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 DX200 controller (switch the
Power ON-OFF switch on each controller to OFF, then back to ON).
An E-STOP (emergency stop) will occur under any of the following
conditions:
• An E-STOP button is pushed in (activated).
• A work-cell access door is opened while the robot is not in TEACH
mode.
• The safety light curtain system is triggered while the MSR positioner
is sweeping.
