2. To signal the dwell position for a cycle on de-
mand application. In cycling, the input is signaled
tostop somewhere in dwell position. This stopping may
be done either by stopping the motor or using a clutch
brake to disconnect the motor from indexer input. Ei-
ther, these methods allow operation of the Index Drive
near its rated capacity (shortest motion time) and, by
controlling the time the indexer stops, give the cus-
tomer his desired dwell time.
CAUTION: There are several ways to misapply the
limit switch. One of the most common problems is fail-
ure to stop the unit in dwell. Starting and stopping in
motion may overload the indexer and open up the
overload clutch (if supplied).
The dwell position can be found by checking the in-
dexer output for movement by means of an indicator
or by observing the appropriate notes in our CAMCO
assembly drawings.
