MPI-16 & MPI-16H POCKET INDEXERS
4-8 Operation
4.3 System Faults
Several events may occur to the MPI-16 during operation that will cause a run-time fault.
A blinking Fault LED will indicate exactly what error has taken place. This section
describes the various error conditions and what action should be taken if one occurs.
1 Blink – Abort Fault ’
Description:
• One of the Abort buttons has been pressed. The MPI-16 is now paused and
the Interlock has been turned off.
Action:
• If the Abort button that was pressed was the Abort/Reset button on the
Remote Panel (or on the MPI-16 itself), press it again to resume operation.
• If the Abort button that was pressed was connected to an external controller,
take whatever action is needed to remove the Abort signal and resume the
program (on the MDC-360, this button is labeled Reset).
• If you wish to reset the MPI-16, hold the Abort/Reset button for two
seconds.
2 Blinks – Pocket Select Fault ’’
Description:
• The selected pocket has exceeded the maximum pocket number that was
determined by the Configuration Switch settings when the MPI-16 was last
reset. The MPI-16 continues to move towards the last valid pocket number
entered, and the Interlock has been turned off.
Action:
• Select a pocket that is within the correct range. Your program will
immediately resume. If you feel that you should be able to access a pocket
but are unable to, check your Configuration Switch settings.
3 Blinks – Over Temperature Fault ’’’
Description:
• The temperature sensor on the MPI-16 has been activated due to excessive
heat (over 100
° C). The MPI-16 has stopped moving, and the Interlock has
been turned off.
Action:
• Cool the system until it has reached 85° C. The system will automatically
restart. Alternatively, you may manually reset the MPI-16, however it will
still be bound by the same 100
° C temperature limit.
