Series 71 – Electric Actuator
Installation, Operation and Maintenance Manual
 ELECTRICAL OPERATION
The motors used in the Bray Series  are of either permanent split capacitor
(PSC) design for single phase line applications or permanent magnet (PM)
design for ACDC power Travel limit switches are mechanical form
(SPDT) with contact rated at A  VAC
The PSC motor is designed for impedance protection such that the current
and self-heating will be limited in cases where the torque capacity of
the unit is exceeded to the point where the motor stalls The PM motor
controllers implement self-resetting over-current protection which will also
limit the current and torque capacity of the motor
 MECHANICAL OPERATION
Mechanically the ratio of the gearing determines the output speed of
the unit The actuator utilizes high efficiency spur gears Positioning is
determined by an indicatorcam shaft which is linked to the output shaft In
the declutched position the manual override drives the output
7.0 ACTUATION
 MANUAL OPERATION
The Bray Series  actuators are provided with a declutchable manual
override system To manually operate the actuator push in the manual
override button and rotate the declutchable lever counter-clockwise until it
reaches the  o’clock position Once the declutchable lever is in position
turn the handwheel until the valve reaches the required position The motor
does not shutoff during manual operation and will continue to rotate the
upper gearing if being commanded by the process Push in the manual
override button and rotate the declutchable lever clockwise until it reaches
the  o’clock position to re-engage the upper gearing and motor drive

 REMOTE OPERATION
CAUTION
 Verify that the main electric power supplied to the actuator is in compliance with
the specifications on the actuator label
 Engaging the handwheel before or during the application of a supply voltage will
prevent the actuator motor from driving the valve to the position commanded by
the process

The back feeding of one actuator by another one wired in parallel is
eliminated by using the S IRB If the actuator is running Open and the
customer switches “instantaneously” to run Closed the Open relay will take
time to “drop-out” and the Close relay will take time to “pull-in” This time
lapse is ~ms The time delay provided by the S IRB will protect the
switches and gears from the controller’s instantaneous command signal
reversal Current draw and field wiring are not affected by the IRB
NOTE The host controller should use a one second time delay for command
signal reversal

• The standard mounting position for the actuator orients the unit with its handwheel
in a vertical plane and parallel to the pipeline
• If the actuator is mounted on a vertical pipe it is recommended that the unit be
positioned with the conduit entries on the bottom to prevent condensation from
entering the actuator through its conduits
• In all cases the conduit should be positioned to prevent drainage into the actuator

Follow the steps below to mount the actuator onto the valve.
• Manually operate the actuator until the output shaft of the actuator is in line with the
valve stem. If possible, select an intermediate position for both the valve and actuator.
• If required, place the proper adapter onto the valve stem. It is recommended that a
small amount of ‘anti-seize’ lubricant be applied to the adapter to ease assembly.
• Mount the actuator onto the valve stem.
• Install the furnished mounting studs by threading studs all the way into the actuator
base. It may be necessary to manually operate the actuator to align the valve and
actuator bolt patterns.
• Fasten the mounting studs in place with furnished hex nuts and lock washers.

WARNING
• Ensure a ground wire is attached to one of the two ground wire locations and
follow proper grounding techniques as required by applicable codes standards and
safety regulations
Standard factory setting of the travel limit switches allows 90° travel between open and
close positions. Cams for each switch are adjustable for applications where less than
90-degree travel is desired between the open and closed positions.
.
•
Manually operate the actuator to the closed position.
• Using a hex key, loosen the set screw on the Close limit switch cam.
• Adjust the cam until it activates the limit switch. The limit switch will “click” when
activated.
• Tighten the set screw.
• Adjust the Closed auxiliary switch such that it advances slightly past the closed limit
switch.
• Repeat in the open position with the open cams.
• Take the actuator cover o. The cover should be kept on hand for reference.
• Wire the actuator as per the wiring diagram attached to the inside of the actuator cover.
NOTICE
• Power and control wiring should use separate conduit entries
• A minimum of  AWG wire is recommended for all field wiring
• Field wiring terminals are push button type with wire clamps and can accept wire
gauge from  to  AWG

11.0 INSTALLABLE OPTIONS
 HEATER
Bray offers an optional heater as a factory installable option for the Series 
actuator to prevent condensation from forming inside the actuator
Units with OnOff actuation use a positive temperature coefficient (PTC)
style heater which has a unique temperature – resistance characteristic The
heater self-regulates by increasing its electrical resistance relative to the
internal temperature The heater does not require external thermostats or
switches to control its heat output VACVAC OnOff units require
dedicated live to power the heater
Modulating units use a resistive element controlled by an on-board
thermostat
NOTICE
The heater must have a constant power supply to be effective
WARNING
The heater surface can reach temperatures in excess of F (C)
