Figure 3. Interrupter contact wear inspection
b. If the scribe mark falls below the top of the
upper support plate, when the interrupter is
closed, the interrupter has reached the end of its
useful life and must be replaced. (See “Vacuum
Interrupters”for replacement procedure.)
8. Check the electrical operation of the recloser:
a. Reinstall the fused pullout switch to energize the
motor circuit.
 If this recloser has been manually tripped while
the motor circuit was de-energized (SPRINGS
DISCHARGED), the motor will run to charge the
closing springs (SPRINGS CHARGED).
b. Momentarily apply 24 Vdc to terminals A (+) and E
(-) of the control terminal board, mounted vertically
along the left edge of the panel board.
 The recloser will close, and the motor will run to
recharge the closing springs for the next closing
operation.
c. Momentarily apply 24-Vdc to terminals A (+) and C
(-) of the control terminal board.
 The recloser will trip open.
d. Electrically open and close the recloser several
times to check its operation; leave in the open
iposition.
9. Check operation of recloser with its control. Checkout
procedures for a recloser with a F3A control, and
for the control only, are described in the applicable
control installation manual: Form 3A electronic recloser
controls refer to S280-75-1, Form 4C microprocessor-
based controls refer to S280-77-1.
IMPORTANT
Form 3A electronic control must be equipped with the
KA1175ME fuse accessory. This accessory supplies a
MDQ-2.5 closing coil control fuse which is required to
operate the closing solenoid.
Controls must not be programmed with reclose
delay intervals that are shorter than 0.5 second. The
instantaneous reclose delay plug must not be used.
The KA1177ME-1 reclose delay plug provides a fixed
0.5 second delay. A maximum of one 0.5 second delay
can be used, successive reclosing operations must be a
minimum of two (2) seconds.
10. Refer to the applicable sections of the “Type VSA12,
VSA16 and VSA20/800 Installation Instructions”, S280-
45-1, for procedures to return the recloser to service.
Manual operation
The recloser can be manually closed and tripped with a set
of operating levers on the operator mechanism inside the
cabinet (Figure 4) or a set of pullrings located externally on
the underside of the cabinet (Figure 5).
To close recloser
Proceed as follows:
1. Apply rated voltage to the input terminal block on the
side of the operator cabinet.
ote:N If closing springs are discharged, the motor will
operate immediately to charge the springs.
