type vsa12, vsa12b, vsa16, vsa20, and vsa20a operation and installation instructions

  MN280063EN   May 2017

iii.  Check that the recloser is open. The contact 

position indicator in the operator cabinet should 

read OPEN. The RESET-TRIP knob should be in 

the RESET position and the spring chargestate 

indicator should read SPRINGS DISCHARGED.

a. If the recloser is closed, trip the recloser 

following the Manual Tripping instructions in 

this section. This will release a latch in the 

tripping mechanism, and energy stored in 

the opening springs will drive the operating 

mechanism to open the recloser contacts. 

The contact position indicator will read OPEN. 

Return the RESET-TRIP knob to RESET.

b. If the spring charge state indicator shows 

SPRINGS CHARGED, close the recloser 

following the Manual Closing instructions 

in this section. This will close the recloser 

contacts and charge the opening springs. The 

contact position indicator will read CLOSED. 

Repeat procedure in Step 3A above.

iv.  Insert the manual closing crank (stored on the 

inside of the operator cabinet door) through the 

hole in the right-hand side of the operator cabinet 

(sealed with a bolt-nut-seal) and onto the drive 

shaft (see Figure 15).

v.   Crank the motor in a counterclockwise direction 

until the springs charge: approximately 150 

revolutions of the motor shaft are required. 

The spring indicator will rotate to the SPRINGS 

CHARGED position.

vi.  Push up the manual closing lever to manually 

close the recloser. This will close the contacts 

and charge the opening springs. The contact 

position indicator will read CLOSED and the 

spring charge-state indicator will show SPRINGS 

DISCHARGED.

vii.  Move the RESET-TRIP knob to TRIP. The recloser 

contacts will trip open and the contact position 

indicator will read OPEN.

viii. Replace the fused disconnect if it was removed. 

4.  To close the recloser contacts with the control:

A.  Apply specified motor voltage (see page 10)
B.   First, push the yellow manual open handle up.
C.  Close the recloser using the microprocessor-based 

control.

5.  To trip the recloser contact using the control:

A.  Trip and lockout the recloser using the 

microprocessor-based control.
