- 1. Local opening of breakers is accomplished as follows:
- a. For electrically operated types, disaita the breaker closing ability by positioning the charging power switc on the breaker front to OFF.
- b. Depress the TRIP pushbutton (left pushbutton where two exist),
- c. Verify the breaker trips and remains open.
- 2. Local closing of manual type breakers (large closing handle) is accomplished as follows:
- a. Pull down the closing handle,
- b. Verify the breaker closes and remains closed.
- c. Investigate the cause if the breaker does not remain closed.
- 3. Local closing of electrically operated type breakers is accomplished as follows:
- a. Open the panel directly behind the breaker on back of the switchgear,
- c. Verify the breaker closing springs are cilarged.
i i
- d. If the breaker closing springs are discharged, perform Step 1) or 2) for l the appropriate size breaker as follows:
- 1) For 2000 or 3000 amp frame sizes, charge the springs as follows-L a) Insert a manual spring charging handle into the slot in the breaker front.
b) Pump the handle until the breaker indicates charged.
- 2) For 600 and 1600 amp frame sizes, charge the springs as follows:
a) Open the door on the breaker cubicle.

NOTE 3.d.9)c)
The pawl carrier is located on the breaker, on centerline, between the silver colored charging motor on the right and the black auxiliary switch assembly on the left. Occasionally, the charging motor will coast to a stop in such a position that the driving pawl does not engage the next tooth on the ratchet wheel.
When the driving pawlis not engaged on the ratchet wheel, a screwdriver blade should be inserted along the right side of the pawl carrier against the roller on the charging motor output eccentric and the roller should be pushed to manually rotate it. The charging handle should then be inserted.
c) Operate handle until the breaker indicates charged.
- e. Lift (or pull) the manual CLOSE lever.

l REMOTE OPERATION OF VALVES FROM 440V MOTOR CONTROL CENTERS NOTE 1 l MVG-8133B is a Power Lockout valve. Power Lockout valvos require both l
Power Lockout and Valve Motor starter relays to be actuatsd simultaneously for remote operation. MVG-8133B starter relays are located in XMC1DB2Y 06EH and XMC1DB2Y 15CD.
- 1. Locate the Motor Control Center Cubicle (s) for the valve to be operated.
- 2. Position the breaker (s) to OFF(RESET).
1
- 3. Open the cubicle door (s).
- 4. Remove the control power fuse for motor starter with fuse pullers. l l
S. Locate the two motor starter relays in the appropriate cubicle.
A V 6. Place a clamp-on ammeter around one of the following:
- a. One heavy wire connected between the top of the motor starter relays and the circuit breaker.
- b. One field motor lead.
- 7. Perform Step 7.a for digital ammeters or Step 7.b for analog ammeters as l follows:
- a. When using digital ammeters, perform the following:
- 1) Ensure switch on face of meter is in C position.
- 2) Depress and hold the red pushbutton on the meter side.
- 3) Verify the display lights up.
- b. When using analog ammeters, perform the following:
l
- 1) Ensure meter pointer is unlocked (switch to left).
- 2) Set Meter Scale to 0-6A.

- 11. Observe current on the ammeter for the following:
- a. If current remains high, release contactor; valve is in the required position already.
. b. If low, release contactor when current begins to rise sharply.
- 12. If applicable, release the Power Lockout relay contactor.
- 13. Re-open the circuit breaker (s).
