StepF
Place the selector handle in the coupled position. Operate
the switch operator electrically to open and to close the
Alduti-Rupter Switch. Observe the toggle mechanisms (if
applicable) and the open stops on the switch. It is likely
that full opening and closing travel will not have been
attained because the travel-limit discs were adjusted to
limit the extent of output-shaft rotation while the switch
operator was in the decoupled position-i.e., a no-load
condition. To attain full stop positions (and overtoggle
positions, where applicable), perform the following:
(a)
If
full opening of the Alduti-Rupter Switch was not
attained, replace the motor-circuit fuseholder and
operate the switch operator electrically to close the
Alduti-Rupter Switch. Remove the motor-circuit fuse-
holder. To increase travel in the opening direction,
retard the opening-stroke travel-limit disc one indica-
tor-plate number. Keep in mind that the direction of
d'isc rof,ation is al:ways the same as that of the output
shaft. Repeat this procedure until full opening travel is
attained.
(b)
If
full closing of the Alduti-Rupter Switch was not
attained, replace the motor-circuit fuseholder and
operate the switch operator electrically to open the
Alduti-Rupter Switch. Remove the motor-circuit fuse-

holder. To increase travel
in
the closing direction,
retard the closing-stroke travel-limit disc one indica-
tor-plate number. Keep in mind that the direction of
disc rotation is always the same as that of the output
shaft. Repeat this procedure until full closing travel is
attained.
StepG
When travel-limit disc adjustments have been completed,
it may be necessary to realign the Alduti-Rupter Switch
position indicators on the switch operator output-shaft
collar with the alignment arrow.
With the switch operator in the fully open position and
then the fully closed position, check the corresponding
switch operator position indicator. In each position, the
corresponding position indicator should be readily visible
from the front of the enclosure.
If
adjustment of either
position indicator is necessary, remove the motor-circuit
fuseholder, loosen the two set screws on the position
indicator, and rotate the position indicator to the desired
position. Retighten the set screws. See Figure 8.
Proceed to Step 18 in the "ADJUSTMENTS"
section.
