G.2 HANDWHEEL OPERATION
Accumulator actuators are equipped with solenoid manual override
levers. This feature enables use of the handwheel with electrical power
off or in trip mode. Units are shipped from the factory with the sole-
noid override levers safety wired in the open position (see figure G1).
They must be in this position for normal operation of the actuator. To
use the handwheel during a power off or trip situation both solenoid
override levers must be moved to the closed position (see figure G2) .

Once both overrides are closed, the handwheel may be operated in
a normal manner. After handwheel use and prior to returning the ac-
tuator to normal service, (power restored or trip signal removed) both
solenoid override levers must be returned to the open position. It is
recommended that both override levers be safety wired in the open
position when the handwheel is not in use.
WARNING!
AFTER USING THE HANDWHEEL, THE OVERRIDES MUST BE
RETURNED TO THEIR OPEN POSITION (FIGURE 1) OR THE UNIT
WILL NOT OPERATE CORRECTLY WHEN POWER IS RESTORED
OR TRIP SIGNAL REMOVED. IF ONLY ONE OVERRIDE IS RE-
TURNED TO THE OPEN POSITION AFTER A TRIP, DAMAGE TO
THE POWER MODULE MAY OCCUR.
