 INTRODUCTION
The Bray Series  is a quarter turn electric actuator with manual override for use on
any quarter turn valve requiring up to  lb-in [ N m] of torque Operating
speeds vary between  to  seconds
 Principle of Operation
The Series  actuator is divided into two internal sections the power center below
the switch plate and the control center above the switch plate Below the switch
plate the gear motor with its spur gear train drives a non-backdriveable worm gear
output The override mechanism for manual operation is also housed here Above
the switch plate is where user required readily accessible components are placed
The indicator shaft assembly limit switches terminal strips torque switches heater
and electronic controllers are all placed here for easy access
External to the unit are adjustable mechanical travel stops a large and easy to read
indicator the unique manual override handwheel and dual conduit entry ports The
external coating is a high-quality polyester powder coat which has exceptional UV
protection and chemical resistance
 Electrical Operation
The gear motors used in the Bray Series  are of either permanent split capacitor
(PSC) design (single phase AC power) or permanent magnet (PM) design (DC
power) Travel limit switches are mechanical form (SPDT) with contacts rated at 
Amp ( PF)  HP  VAC
In cases where the torque capacity of the unit is exceeded to the point where the
motor stalls a thermal protector switch built into the PSC motor windings will
automatically disconnect the motor power and prevent overheating Once the motor
cools suciently the thermal protector switch will reset automatically
Optional torque switches are available in all units to prevent the possibility of stalling
the motor thus reducing the possibility of an inoperable thermal cool down period
Torque switches installed by Bray are factory adjusted to the output torque rating
of the unit using electronic torque testing equipment
 Mechanical Operation
Mechanically the ratio of the gear motor determines the speed of the unit The gear
motor utilizes high eciency spur gears with various ratios for the dierent speeds
Initial gear reduction through the spur gears is then transferred to the worm shaft
The final gear reduction and output is through a non-backdriveable worm gear set
Positioning is determined by an indicatorcam shaft which is linked to the output
shaft In the declutchable condition the manual override drives the worm shaft
when engaged

 STORAGE
WARNING
Actuators are not weatherproof unless they are properly installed on the valve or
prepared for storage Bray cannot accept responsibility for deterioration caused
on-site
Bray Series  is not weatherproof until the unit is properly installed or all conduits
and applicable port connections are sealed o and prepared for storage The units
may be shipped with temporary covers to prevent foreign matter from entering
through the conduit openings however the user is responsible for replacing with
the proper sealing plugs to support its NEMAIP ratings
To prevent condensation from forming inside the unit maintain a near constant
external temperature and store indoors in a well ventilated clean dry room
The temperature shall be between F (C) and F (C) with a relative
humidity less than 
Store units away from vibration and direct sunlight exposure and place units on a
shelf or wooden pallet in order to protect against dampness
Keep units covered to protect against dust and dirt if storing for long term placing
the unit inside a plastic sealed bag may be preferred
Bray cannot accept responsibility for deterioration caused on-site once the cover is
removed or due to improper storage
For units with an internal heater power should be supplied to the heater via conduit
entry with an appropriate sealing gland

 ACTUATION
 Manual Operation
The manual override operates similar to a watch adjusting knob To engage the
manual override simply pull the handwheel to its outermost position A yellow stripe
is revealed to visually indicate manual override engagement as shown in Figure 
The two handwheel positions engaged and disengaged are held in place with the
use of spring plungers The handwheel remains in position until physically moved
Yellow Stripe
Figure  - Handwheel is engaged revealing the yellow stripe
Once the manual override is engaged rotating the handwheel in the clockwise
direction will rotate the output shaft in the clockwise (close) direction and vice-
versa
To disengage the manual override the handwheel needs to be pushed towards the
actuator until the ‘yellow stripe’ is hidden
CAUTION
A label on the handwheel hub warns users not to exceed a specific ‘rim pull’ force
for each size of actuator
If the ‘rim pull’ force is exceeded the roll pin securing the handwheel onto the
manual override shaft is designed to shear thus preventing serious internal gearing
damage
 Remote Operation
CAUTION
1. Verify that the main electric power supplied to the actuator is in compliance with
the specifications on the actuator label.
2. Engaging the handwheel before or during the application of a supply voltage
will prevent the actuator motor from operating.
3. If torque switches are installed in the actuator, an over-torque condition will
prevent the actuator motor from operating in the direction of fault.
