the Flash RAM write cycle, the Flash data may be lost or corrupted. If this happens, it is necessary to
reload both the robot PAC files and any user programs that were stored in Flash RAM. This problem
should typically not be encountered by a user unless the user is changing configuration files in the robot
and fails to wait a sufficient amount of time for the flash to be saved before turning off power.
Precise maintains a record of PAC files shipped with each robot Serial Number. If the PAC files have
been corrupted, it is possible to get a backup copy from Precise. The backup copy will contain the factory
configuration and calibration data, but will not contain any changes, including any new calibration data,
made after the robot has left the factory.
In order to allow the controller to recover from corrupted PAC files, a set of recovery boot up PAC files is
loaded in the system area of the Flash.
To configure the controller to boot up in recovery mode the user must:
1.
Obtain a set of backup PAC Files from Precise or local backup.
2.
Remove the screws holding the connector panel in the base of the robot to access
the PCA.
3.
Move Jumper J9 (System Reset) so that it connects the two jumper posts. This will
cause the factory default configuration files to be loaded at controller boot up.
4.
Cycle robot power to reboot the controller.
5.
Follow the procedure above for updating PAC files.
