INTRODUCTION
Beck’s Group 42 actuators are designed to
meet the actuation needs of long stroke linear
applications. Typical applications include burner
air registers and OFA port dampers, but they can
be used on any application requiring up to 18
inches of linear stroke. Employing Beck’s unique
design characteristics, reliability and quality into
a long stroke linear actuator design lls a much
requested slot in the Beck family of products.
As with all Beck actuators, the Group 42 is
designed for simple installation, no duty cycle
limitations, excellent performance and little or no
required maintenance.
Ideally suited for harsh industrial environments,
the Group 42 handles long stroke applications
requiring up to 1,000 lbs. (4 450 N) of thrust. The
design employs a highly e󰀩cient ball screw coupled
with a time-proven Beck motor and o󰀨ers consistent,
repeatable positioning as precise as 0.25% of span.
Like all Beck actuators, the Group 42 incorporates
a heavy-duty, weather-proof, cast aluminum body.

POWER AND SIGNAL WIRING
The Group 42 actuator has a pair of 3/4"
NPT threaded holes for signal and power
conduit connection. 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 must be routed to the
actuator separately and be either shielded cables
or installed in conductive conduit and/or cable
trays.
All signal and power connections are made
on the terminal board. Typical wiring connections
for each Group 42 control option are described
on the following pages. A specic wiring diagram
is a󰀩xed to each actuator shipped.
All actuators are furnished with two auxiliary
switches. Wiring connections for these are
described separately. In addition, a safety
ground is required for all actuators and is located
on the baseplate of the control module.
NOTE: Customer wiring inside the control
module must be properly dressed and routed
to prevent damage to wires from the control
module cover.

Auxiliary Switches
Customer connections to the auxiliary switches are on the terminal board. Switch 1 connects to terminals
6, 7 and 8. Switch 2 connects to terminals 3, 4 and 5. Each switch is form C, rated for 1 amp at 120 V ac.
There is no electrical connection between the two switches. S1 is factory set to operate 2% of the travel
range before the Retract travel limit. S2 is factory set to operate 2% before the Extend travel limit. See page
14 for additional information about setting the auxiliary switches.
Option 7, Modulating
Analog Position Control with Loop Powered Position Feedback Signal
Customer must supply two wires to power the drive: One 120 V ac line (terminal 1), and one neutral (terminal
2). Customer must supply two wires for the analog input control signal: Connect to terminal 11 (-) and to terminal
12 (+). The loop powered position feedback signal must be connected to a “2-wire” type analog input that
provides a dc voltage over the signal wires (a dc voltage power supply must be wired in series with the signal
wiring). If the dc supply is 24 to 35 volts, connect to terminal 14 (-) and to terminal 15 (+). If the dc power supply
is 36 to 45 volts, reverse polarity and connect to terminal 14 (+) and to terminal 15 (-).
Analog Position Control with Drive Powered Position Feedback Signal
Customer must supply two wires to power the drive: One 120 V ac line (terminal 1), and one neutral
(terminal 2). Customer must supply two wires for analog control: Connect to terminal 11 (-) and to terminal
12 (+). Customer may supply two additional wires to monitor the analog position feedback signal: Connect to
terminal 13 (-) and to terminal 14 (+). The drive’s feedback circuit power supply is derived from the 120 V ac
line, therefore the feedback signal must be wired to a "4-wire" type, non-powered analog input.

Option 5, Modulating
Direct AC Control with Loop Powered Position Feedback Signal
Customer must supply three wires to directly control the actuator motor direction: One 120 V ac line
to run Extend (terminal 10), one 120 V ac line to run Retract (terminal 9), and one neutral (terminal 2).
Customer may supply two additional wires to monitor a loop powered position feedback signal. The loop
powered position feedback signal must be connected to a “2-wire” type analog input that provides a dc
voltage over the signal wires (a dc voltage power supply must be wired in series with the signal wiring). If
the dc supply is 24 to 35 volts, connect to terminal 14 (-) and to terminal 15 (+). If the dc supply is 36 to 45
volts, reverse polarity and connect to terminal 14 (+) and to terminal 15 (-).
Direct AC Control with Actuator Powered Position Feedback Signal
Customer must supply three wires to directly control the actuator motor direction: One 120 V ac line
to run Extend (terminal 10), one 120 V ac line to run Retract (terminal 9), and one neutral (terminal 2).
Customer may supply two additional wires to monitor the analog position feedback signal: Connect to
terminal 13 (-) and to terminal 14 (+). If position feedback monitoring is desired, a 120 V ac line must
be connected to terminal 1. The drive’s feedback circuit power supply is derived from this 120 V ac line,
therefore the feedback signal must be wired to a “4-wire” type, non-powered analog input.
Option 3, Open/Close
Direct AC Control
Customer must supply three wires to directly control the actuator motor direction: one 120 V ac line to run
Extend (terminal 10), one 120 V ac line to run Retract (terminal 9) and one neutral (terminal 2).

80-0042-00, Rev. 06.9
Power and signal wires must be routed to the
actuator separately and be either shielded cables
or installed in conductive conduit and/or cable trays.
Shielded, twisted pair cables should be used
for signal connections to avoid being a󰀨ected by
electrical noise. These signal wires, based on Noise
Susceptibility Level (NSL) per IEEE-518, fall into the
level 1 classication. A braided shield will be more
e󰀨ective 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 drive. Raceways such as conduits and trays
have to be grounded at both ends to properly meet
immunity requirements.
A large, clearly labeled terminal block in the
actuator is enclosed in a separate, gasketed metal
enclosure. Terminals will accommodate up to 12
AWG (3.31 mm2) wiring.
CAUTION
Always close covers immediately
after installation or service to prevent
moisture or other foreign matter
from entering the actuator.
Refer to the wiring diagram furnished with your
Beck actuator for proper AC power and signal
connections. 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 drive.
Your Beck actuator has been supplied to match
the signal source in your control loop. If it does not
match, a 250 ohm input resistor may be added or
removed to obtain the proper match. Consult the
factory for details.
For maximum safety, and to comply with
national and international standards, the Beck
actuator body is required to be grounded. Use
one of the two grounding terminals in the wiring
compartment of the actuator to make this
connection. Wire size 12 AWG (3.31 mm2) is
recommended for this purpose.
CONDUIT ENTRIES
Conduits are provided for power and signal
wiring. Temporary plugs are installed in the
conduits 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.
