System Recovery
Under certain conditions you will be required to clear an alarm or error. The
paragraphs below describe the different types of alarms and errors you may
encounter and how to remedy them when you do.
5.3.1
Alarms and Errors
Alarms and errors will cause the program to stop. There are three levels of alarms
and errors: Error Messages, Minor Alarms, and Major Alarms. For more detailed
information about alarm recovery, refer to manipulator manual that came with
your system.
Error Messages
These are simple errors such as pressing the START button when the robot is not in
PLAY mode, or enabling the programming pendant without the servo power being
live. Errors like these are cleared by pressing the CANCEL button on the
programming pendant.
Minor Alarms
Minor alarms are usually programming errors. Minor alarms might occur if a circle
has been programmed with fewer than three circular points, etc. These alarms are
cleared by pressing the SELECT soft key on the programming pendant.
Major Alarms
Major alarms are hardware failures. Major alarms might occur because of a servo
tracking error or an abnormal speed and are usually associated with crashes. To
clear these alarms, you must turn off the controller and then turn it on again.
5.3.2
Error Messages
Door Time Out Error:
A time function has been built into the CIO of the controller. If the door fails to
reach the intended position within the allotted time, the alarm will occur and stop
the system operation. This condition would occur if the door motor fuse is blown,
or if the time has been improperly set.
Gas Flow Error:
A gas flow input has been implemented in the controller CIO. This input will
trigger an alarm in PLAY mode only. User must attach contact to input for proper
operation.
Water Flow Error:
A water flow input has been implemented in the controller CIO. This input will
trigger an alarm in PLAY mode only. User must attach contact to input for proper
operation.
5.3.3
Door Default Settings
The door default function is coded into the CIO of the controller. This function will
detect if the Door Open and Door Closed switches are both on at the same time. If
this fault occurs either the door up or door down switches have failed and should
be replaced before system operation continues.that
