1. Remove the rear bolt from position (lA) of the spring stop (2)
located on the upper right angle frame. On 1200A switches it may
be necessary to loosen the front bolts of the right hand barrier
to have access to the bolts.
2. Rotate the stop until it is vertical, replace the bolt that had
been removed in the lower location (1) and tighten.
3. The SE-lOOE mechanism must be put into the manual operation con
dition before operating with the manual handle. Disengage the
electrical operator by sliding the yellow pawl block toward the
center hub using a screw driver or other small tool Fig. 10.
When the switch is closed the pawl will appear in the left hole,
when open the right hole.
4. Using the normal operating handle rotate in a counterclockwise di
rection (direction of close) until the spring yoke on the right
contacts the stop.
5.
Remove operating handle and insert maintenance handle (2) Fig. 3
on main square shaft and screw the blocking pins (3) Fig. 3 in the
left and right spring guide at (4) Fig. 2. The springs are now
safely blocked and the maintenance handle will open and close the
switch for adjusting purposes.
Mechanism
The upper buffer stops (3) Fig.
5
located on either side of the mecha
nism at the ends of the main crank shaft, must be adjusted to position
the operating rod cranks when the switch is closed. Operate the switch
to the fully closed position.
The operating rod must go over toggle approximately -k" at the crank
connection when the switch is closed.
A
simple means of measuring
the correct toggle angle is to place a straight edge along the upper
side of the operating rod and extend it until it is over the square
main shaft (10) Fig. 6. The dimension from the straight edge to the
closest corner of the square shaft should be l/4" to 3/8".
If adjustment of the stop is necessary, remove the cotter pin holding
the stop
Fig.

and move washers and metal shims from the front to
the rear
the reverse) until the proper toggle angle is obtained.
Adjust the stops at both ends of the main shaft the same amount to keep
them balanced.
The operating rod must fully close the switch primary blades to obtain
the correct primary finger wipe.
With the switch in the closed position, pull the top of the primary
�
blades to the front with your hands to remove connection clearances.
There should be 1/64" to 1/32" clearance between the buffer (8) Fig. 7
