APPENDIX - Continued
It should be noted particularly that reversal of the
motor direction reverses only the direction of rota-
tion of the output shaft and travel-limit discs. The
identity of the opening-stroke and
closing-stroke
travel-limit discs (which will be adjusted later) will
remain unaffected.
( e) In the event that the direction of rotation of the travel-
limit discs noted in ( c) above is opposite to the direc-
tion displayed in the cutaway section on the outer ring
of the closing-stroke travel-limit disc, remove the posi-
tioning screws on the outer ring of the closing-stroke
I
travel-limit disc. See Figure 10. Rotate the outer ring
until the desired direction is displayed in the cutaway
section. Replace the positioning screws.
(f) Reinsert the motor-circuit fuseholder and operate the
switch operator to the open position.
(g) If the direction of output-shaft rotation to open the
Alduti-Rupter Switch is opposite to that displayed in
the cutaway section on the outer ring of the opening-
stroke travel-limit disc, change the direction displayed
as indicated in (e) above.
