INTRODUCTION
This manual contains the information needed for
the operation and maintenance of the Beck 11-483
multi-turn actuator manufactured by Harold Beck &
Sons, Inc. of Newtown, Pennsylvania.
The 11-483 is a rugged, multi-turn addition to
the G11 family of actuators and shares the same
time-proven reliability, features, and performance
advantages. For applications requiring up to 120
lb-ft (163 N•m) of actuator torque, the 11-483 is
available with multiple travel span options, ranging
from 5 turns to 408 turns.

SAFETY PRECAUTIONS
WARNINGWARNING
Installation and service instructions
are for use by qualied personnel
only. To avoid injury and electric
shock, do not perform any servicing
other than that contained in this
manual. Please read and understand
the appropriate sections in this
manual before attempting to install
or operate your actuator.
STORAGE INFORMATION
Beck actuators should be stored in a clean,
dry area where the temperature is between -40°
and 85°C (-40° to 185°F).
Damage due to moisture while in storage is
not covered by warranty.
INSTALLATION—MECHANICAL
See the instructions beginning on page 9 for
details regarding mechanical installation. Refer
to the outline dimension drawings for physical
dimensions and required clearances.
VALVE ACTUATOR INSTALLATIONS
CAUTION
Working with valves installed in a
pipeline can be dangerous. Take
appropriate precautions when
mounting to installed valves.
INSTALLATION—ELECTRICAL
See the instructions beginning on page 10 for
details regarding electrical installation.
CAUTION
For maximum safety, the Beck
actuator body should be grounded.
Use the green grounding screw
in the wiring compartment of the
actuator.
CAUTION
Always close covers immediately
after installation or service to prevent
moisture or other foreign matter
from entering the actuator.
CONDUIT ENTRIES
Conduit entries are provided for power and
signal wiring. Temporary plugs are installed in the
conduit entrances at the factory for shipping only
and are not intended for permanent use. Prior
to actuator operation, all conduit entrances must
be properly sealed in accordance with National
Standards or Regulatory Authorities.
PRECAUTIONARY INFORMATION
80-1100-24, Rev. 1.1
811-483 COMPONENTS
COMPONENT LOCATION
MODES OF OPERATION
There are two basic modes of operation:
• Handwheel—local mechanical control
• Handswitch—local electrical control
Either of these modes can be used to test basic
operation of your actuator during start-up.
HANDWHEEL
The Handwheel permits manual operation
of the actuator without power. The Handwheel is
coupled directly to the motor shaft at the rear of the
motor housing and it rotates when the motor runs.
If power is available, the Handswitch must
be moved to the STOP position before manually
operating the Handwheel.
HANDSWITCH
A Handswitch allows local electric control at
the actuator. In either of the STOP positions, the
motor is blocked from running. In the CW or CCW
positions, the motor runs to move the output shaft
in the corresponding direction. When moving the
output shaft using the Handswitch, the motor will
stop when the limit switches are reached.

INSTALLATION Mechanical
INSTALLATION—MECHANICAL
The 11-483 actuator may be installed in any
convenient orientation, because the gearing
does not require an oil bath. Refer to the outline
dimension drawings for physical dimensions and
required clearances.
VALVE INSTALLATIONS
CAUTION
Working with valves and gates can
be dangerous. Take appropriate
precautions when mounting to
installed valves or gates. Follow
manufacturer precautions.
Whenever an actuator is being mounted
on a valve, refer to the valve manufacturer's
maintenance manual for specific valve-related
instructions. Consult the Beck Valve Mounting
Specification sheet shipped with the actuator for
specific instructions on assembly of the Beck
actuator and mounting hardware to the gearbox
or valve. It is good practice to remove the valve
from service if possible.

POWER QUALITY
Power quality disturbances such as power
outages, transient voltages, harmonic distortions,
and electrical noise will adversely affect your
actuator performance. Protecting your actuator
from these conditions can reduce downtime and
promote longer life for the equipment. Following
the industry accepted standards below will help
protect your actuator.
aSelect wiring materials according to the
correct ampacity ratings dictated by national
and local regulations.
aShielded, twisted pair cables can be used for
signal connections to avoid being affected by
electrical noise. These signal wires, based
on Noise Susceptibility Level (NSL) per
IEEE-518, fall into the level 1 classification.
A braided shield will be more effective than
a wrapped foil shield. Signal wire shields
should be connected to the actuator casting
grounding screw. If grounding at the signal
source is required, then the shield should not
be grounded at the actuator.
aRaceways such as conduits and trays must
be grounded at both ends to properly meet
immunity requirements.
aAn AC power ground connection should be
made between the power source and the Beck
actuator. Grounding connections including
wire and metal conduit are permitted, but the
actuator-grounding conductor may not be
connected to a structured metal frame of a
building.
aSurge suppression equipment that meets
Underwriters Laboratory (UL) Standard 1449
may be used to protect against transient
voltage conditions.
aPower Conditioners may be used to regulate
the supply voltage and maintain a constant
voltage level. They are helpful in protection
against voltage sags and swells, as well as
some measure of electrical noise protection.
aHarmonicltersmaybeusedtominimizethe
eectsofsupplyvoltagewaveformdistortions
and are used in applications that incur a large
amount of high-frequency electronic noise.
CAUTION
Always close covers immediately
after installation or service to prevent
moisture or other foreign matter
from entering the actuator.
ELECTRICAL INSTALLATION
Two 1” N.P.T. conduit connections are provided
for power and signal wiring to the actuator.
Conduits should be routed from below the actuator
so that condensation and other contaminants flow
away from the conduit. All conduit entrances must
be properly sealed in accordance with National
Standards or Regulatory Authorities.
Power and signal wires should be routed to
the actuator separately and be either shielded
cables or installed in conductive conduit and/or
cable trays.
Refer to the wiring diagram furnished with
your Beck actuator for proper AC power and signal
connections. The customer must supply 120 Vac to
power the actuator (standard configuration). The
120 Vac line connects to terminal C and neutral to
terminal B. Other available power options include
208, 240 & 480 Vac.
It is advisable to provide normal short circuit
protection on the AC power line. A copy of the
wiring diagram is shipped with each actuator and
is fastened to the inside of the terminal block cover.
If there is no wiring diagram available, you may
obtain a copy from Beck by providing the serial
number of your actuator.
For maximum safety, the Beck actuator body
should be grounded. Use the green grounding
screw in the wiring compartment of the actuator.
TERMINAL SCREW TORQUES
Each terminal screw should be torqued to the
proper specification upon landing the wire.
