MPI-16 & MPI-16H POCKET INDEXERS
Operation 4-1
4 Operation
Regardless of whether you will be running the MPI-16 in Manual or Automatic mode, be
sure that you have read Section 3 and have set up your Pocket Indexer correctly. The
Configuration Switch settings dictate how the MPI-16 operates.
Setting up for automatic operation is more involved than manual operation, but it can
ultimately lead to greater automation and significant timesaving.
4.1 Controlling the MPI-16 Manually
Controlling the MPI-16 manually requires the Remote Panel. On your Remote Panel, flip
the switch labeled Auto / Man. to the Man. setting. This activates the Pocket Select and
Speed Select knobs on the Remote Panel instead of allowing input from an external
source, such as a Deposition Controller. Also, on the MPI-16 itself, make sure that the
Speed Select switch is set to Remote, indicating that the speed setting is to come from
the Remote Panel.
Regardless of whether you will be running the MPI-16 in Manual or Automatic mode, be
sure that you have read Section 3 and have set up your Pocket Indexer correctly. The
Configuration Switch settings dictate how the MPI-16 operates.
Manual operation is very straightforward. Upon reset (unless Circular Mode was set), the
MPI-16 finds Home (locates the first pocket). After Home is found, you are free to move
the Pocket Select and Speed Select knobs to any position you desire. The Rotation
Mode Configuration Switch determines the method that is used to get to the selected
pocket (see Section 3.3).
Note that in the standard version MPI-16, the Speed Select setting only applies to Banana
Pocket and Circular Mode, and not the seek home speed (fixed at 16 RPM). However, in
the high torque version MPI-16H, the Speed Select setting applies to all modes: seek
home, Banana Pocket and Circular Modes.
If you select a pocket out of the range set by the Number of Pocket switch, the Pocket
Indexer will continue to go to the last valid pocket that it sensed, but it will not consider
itself “In Position,” nor will the Interlock relay be turned on.
The Abort/Reset button on the Remote Panel serves two purposes. Pressing it once will
cause the indexer to pause and the Interlock to turn off. Pressing it again causes the
process to continue from where it left off. At any point, though, if you hold the
Abort/Reset button for two seconds, the system will reset itself as if the power were
turned on.
4.2 Controlling the MPI-16 Automatically
Controlling the MPI-16 automatically requires an external Deposition Controller or PLC.
Combining external control with the MPI-16 Pocket Indexer provides a fully automated
solution for your deposition process. Although not required when controlling the MPI-16
automatically, the Remote Panel is still a very useful add-on. Having a Remote Panel in
