MAN. Note that this switch has a locking feature. To change its position, you must
first pull the locking collar out toward you.
8 Set the front-panel thumbwheel to position 1, if it is not already at that position.
9 Using the ON/OFF switch on the control unit’s front panel, switch on the indexer. If
the internal DIP switches are set for a full circle evaporant carousel, the drive unit’s
output shaft will begin rotating continuously at its highest speed. If the DIP switches
are set for any other type of source, the indexer will stop at the factory-set home
position for pocket 1 after proceeding through various rotations involved in its
initialization routine.
10 Change thumbwheel setting to select pocket 2. The indexer rotates to the pocket -2
position after going through rotations that vary depending on the settings of DIP
switches 1-5.
11 Use the thumbwheel to select other pockets and observe the rotation of the output
shaft.
12 When you have completed the bench-test, switch off the control unit, disconnect the
AC power cable from the rear panel, and disconnect the motor cable from both the
control unit and the index drive unit.
Section 3.8: System Installation
The standard unit is designed to be used with the E-Beam source, which has a 4 to 1
reduction within the source or a 4 to 1 reduction between the Indexer output shaft and the
source. Thus 360 degrees of rotation of the Indexer shaft will cause a 4 pocket source to
rotate 90
°.
The most cost effective system installation is accomplished by the purchase of either
the 1” or 2 ¾” Rotary Feedthrough Indexer and Adapter Kits from Sycon. If system
configuration of space does not allow the use of these standard items, the Indexer should be
rigidly mounted and the Indexer drive shaft be appropriately attached (minimum slop and
backlash) to the airside of the Rotary Feedthrough.
A one-to-one directed connector is needed between the output shaft of the Indexer and
the airside of the Rotary Vacuum Feedthrough. Sycon stocks the following items to assist in
making the Mechanical connection from the output shaft of the Indexer to the air side of the
Rotary Vacuum Feedthrough:
