3. OPERATION OF WINCH
3.3. The electric brake is a disc type, normally set by me-
chanical spring pressure. It is released automatically when
electric power is supplied to its solenoid. In other words,
brake release occurs simultaneously with the powering
of the motor and the brake locks automatically when the
motor's electric power is turned off.
3.4. REEL-IN: Depress the IN/FORWARD push-button.
Continue to reel in wire rope at rated load and speed until
motor reaches stall. To stop the winch, release the IN/
FORWARD button and the brake will engage.
WARNING! FAILURE TO STOP POWERING THE WINCH
AFTER MOTOR REACHES STALL CAN RESULT IN
MOTOR BURNOUT.
3.5. REEL-OUT: Check to see if the Locking Dog is engaged.
If it is not, depress the OUT/REVERSE push-button. This
will allow for the pay-out of the wire to the desired length.
To stop the winch, release the OUT/REVERSE button and
the brake will engage. If the Locking Dog is engaged,
manually rotate the counterweight towards the back of the
winch. Depress the IN/FORWARD push-button until the
counterweight rotates the locking dog out of engagement.
Release the IN/FORWARD push-button and depress the
OUT/REVERSE push-button. This will allow for the pay-out
of the wire to the desired length. To stop the winch, release
the OUT/REVERSE button and the brake will engage.
3.5.1. If the counterweight does not rotate the locking dog
out of engagement the usual cause is that tension on the
wire rope exceeds the stall pull of the winch. In this case,
reposition the vessel to decrease the tension on the wire
rope.
WARNING! FAILURE TO DISENGAGE THE LOCKING
DOG PRIOR TO REELING OUT CAN RESULT IN MO-
TOR/WINCH FAILURE.
WARNING! KEEP ALL FINGERS, LOOSE CLOTHING
AND ANY FOREIGN OBJECTS AWAY FROM WINCH
WHILE IN OPERATION.
3.1. The W. W. Patterson electric winch is designed for
easier operation and longer life. If sized correctly, installed
properly and maintained regularly, this winch will last many
years.
3.2. The electric brake, electric motor and gearhead are
integrally mounted to the winch frame. Normally, a two
button (IN/FORWARD and OUT/REVERSE) control sta-
tion is used to operate the winch. Each button should be
wired in such a way as to provide for automatic stopping
the moment either button is released.
WARNING! ONLY A QUALIFIED ELECTRICIAN SHOULD
BE ALLOWED TO WIRE CONTROL BOX AND REMOTE
STATION OF A WINCH.
