SPRING RECHARGE AFT ER CLOSING
When the closing cycle has been initiated and the cams
(7, Figure 7) begin to turn, the motor cutoff switch (10,
Figure 3) resets itself. A "b" auxiliary switch of the
breaker opens de-energizing the closing solenoid (13, Figure
7). The close latch
(9,
Figure 7) returns to its reset position
and the close latch check switch (16, Figure 3) closes and
energizes the spring charging motor (1). The closing
springs (6) are then recharged as described earlier.
T R I PPING CYCLE
Energizing the trip solenoid
(17,

will drive
the trip latch (18, Figure 3) a

ay from latch roller (20,
Figure 3)
on the four bar linkage
(12,
Figure
3).
This
allows the four bar linkage to collapse and the breaker
contacts will open. If the closing springs (6) are in t h e
charged position, the linkage reset spring (11, Figure 7)
will immediately reset the four bar linkage (12). If the
closing springs (6)

ELECTRICAL CON TROL
The normal
control for
this
operator
is contained in a
control panel mounted at the. rear of the unit. It consists
of
motor cutoff switch (10, Figure 3), anti-pumping relay
(30, Figure 3), and the close latch check switch (16). The
typical control arrangement's elementary diagram
is
shown
in Figure 9. (Check schematic furnished with switchgear
as
wiring arrangements may vary.)
Spring Charging
The spring charging motor power is supplied through
terminals 3 and
4
(Figure 9). The mechanical interlock is a
switch operated by the breaker release lever (foot lever)
which opens the motor circuit when the lever is depressed.
The close latch check switch is closed when the close
latch
(9, Figure 3) is in the reset position. The 88 switches
are shown with the closing springs discharged. When the
control Is energized, the motor starts to charge the springs.
The
88
switch is operated by
a
roll pin striker
(37,
Figure
3)
mounted in the ratchet wheel
(4,
Figures 3 and 16).
As
the
ratchet wheel and drive blocks charge the springs, the
ratchet wheel revolves to the position of full compression.
dead center. Beyond dead center position, the springs aid
rotation and cause the motor cutoff switch striker to
depress the actuator (35, Figure 3) of the 88·1 s w i tch ,
opening the motor circuit and the 88·3 contact in the anti·
pumping relay
circuit. The
spring
charging
motor coasts
to
a stop with the driving pawl (2, Figure 3) oscillating freely
on the smooth portion of the ra t c he t wh ee l .
