arrow plate, remove the arrow-plate mounting
screws and remount the arrow plate, exposing its
opposite side.
(c) With the manual operating handle in its storage
position and the
selector
handle
in
the decoupled
position,
reinsert the motor-circuit fuseholder.
Open the pushbutton protective cover. and operate
the switch operator by means of the externally
mounted "Open-Close" pushbuttons,
if
provided,
or
in their absence, by momentarily jumpering
terminals
1
and
8
to open, and
1
and
9
to c1ose.v
Note
the direction
in
which
the travel-limit discs
rotate
when theswitch
operator
closes.
The direction
should agree with the temporary direction mark
previously made on the top of the enclosure and
with the direction displayed in the cutaway section
on the outer ring
of
the travel-limit discs. See Fig-
ure
6.
(As
a
matter
of
information, the direction
of
rotation of the travel-limit discs
is
always the
same
as
the direction of rotation of the output
shaft.)
(d) In the event that the direction of rotation of the
travel-limit discs noted in (c) above
is
opposite to
the temporary direction mark previously made in
(a) above,
a
reversal of the motor direction
will
be
necessary.
Remove
the mtordrcuit
fuseholder
to
avoid accidental or remote energization
of
the
control circuit. Interchange the
"Sl"
and
"S2"
motor
leads connected to terminals
4
and
5
on the terminal
block in the switch operator enclosure.
It should be noted particularly that reversal of
the motor direction reverses only the direction
of
rotation 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 direction displayed in the cutaway section on
the outer ring
of
the closing-stroke travel-limit disc,
remove the positioning screws on the outer ring
of the closing-stroke travel-limit disc. See Figure
6.
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 Circuit-Switcher
is
opposite to that displayed
in the cutaway section on the outer ring
of
the
opening-stroke travel-limit disc, change the direc-
tion displayed
as
indicated in (e) above.

The travel-limit switch (coupled to the motor), which
governs the extent of output-shaft rotation in the
opening and closing directions, includes
six
contacts
that are operated by cam-actuated rollers. Positioning
of
the cams to properly engage the rollers
is
facilitated
by the travel-limit discs (upper one
is
the opening-
stroke travel-limit disc; lower one
is
the closing-stroke
travel-limit disc
j.
Adjustment of the opening-stroke travel-limit disc
(and therefore the associated cams)
is
accomplished
as
follows:
(a)
Remove
the motorcircuit
fuseholder.
(b) Place the selector handle in the
coupled
position
and manually crank the Circuit-Switcher to the
open position.
(c)
For
the Circuit-Switcher style installed and its
number of interrupting gaps per pole-unit, deter-
mine from Table
I
the "Indicator-Plate Number" to
which the opening-stroke travel-limit disc
is
to be
rotated. Select the indicator-plate number from the
"Opening-Stroke Adjustment-Clockwise to Open"
column
if
the disc and output shaft rotate in the
clockwise direction to open the Circuit-Switcher,
or
from the "Opening-Stroke Adjustment-Counter-
clockwise to Open" column
if
the disc and output
shaft rotate in the counterclockwise direction to
open the Circuit-Switcher.
(d)Grasp the handwheel and turn it to the extent
possible in
a
direction
opposite
to the direction the
output shaft rotates to open the Circuit-Switcher.
See Figure
6.
(e) With the handwheel held in the position indicated
above, raise the opening-stroke travel-limit disc
approximately
3/16
of an inch and rotate the disc
until the arrow on its outer ring
is
in line with the
number on the indicator plate
as
specified in Table
I.
Lower the disc, make
sure
it
is
engaged, and release
the handwheel.
For
switch operators with optional remotecontrol blocking switch
(suffix
u-Yn),
opening the pushbutton protective cover prevents remote
operation
of
the switch operator.
