1 Description
Flowserve Worcester Controls Series 75 actuators are reversible
electric quarter-turn actuators. Standard units can provide up to
1200 in-lb of torque and have capacitor-start, capacitor-run motors
and permanently lubricated gear trains. These actuators are equipped
with integral thermal overload protection with automatic reset and
internal adjustable limit switches. In the event of electrical power
failure, W, X and Z models feature manual override capabilities.
c WARNING: Series 75 actuators are electromechanical
devices subject to normal wear and tear. Actuator life is
dependent upon application and environmental conditions.
If applied in hazardous services such as, but not limited
to, media temperature extremes, toxins and flammables
(or other services where improper or incomplete operation
could produce a safety hazard), it is incumbent upon the
system designer and the user to provide proper warning
devices such as temperature sensors, oxygen sensors
and flow sensors. At elevated temperatures the duty cycle
has to be derated; consult factory. Flowserve also recom-
mends that the optional auxiliary limit switches be used
for monitoring and/or electrical interlock. A heater with
thermostat as well as drain/breather fitting (V53 option) are
recommended for humid environments when moisture may
condense inside the housing. Please note that weatherproof
enclosures will “breathe” over time and condensation within
the housing will result.
a CAUTION: Flowserve recommends that all product that
must be stored prior to installation be stored indoors, in
an environment suitable for human occupancy. Do not
store product in areas where exposure to relative humidity
above 85%, acid or alkali fumes, radiation above normal
background, ultraviolet light, or temperatures above 120°F
or below 40°F may occur. Do not store within 50 feet of any
source of ozone.
a CAUTION: For wiring of actuator, please refer to wiring
diagram(s) located inside of actuator cover. Wiring dia-
grams are also included in this manual for reference.
a CAUTION: The PLC/Process Controller logic should never
set bits 5 & 6 on (1) at the same time in output word 1.
These bits control actuator CCW and CW rotation, and dam-
age to the relay interface module and motors will result if
these bits are set on (1) simultaneously. The output word 1
corresponds to an actuator at Address 1.
The DeviceNet Interface feature of this equipment permits simple
DeviceNet bus connection and communication. Position indication
is accomplished via the DeviceNet bus, and integral Light Emitting
Diodes (LEDs) display the status of inputs and outputs.
The DeviceNet Board has two outputs and three inputs. Each output
is used to control the CW or CCW direction of rotation of the actua-
tor via integral interface relays. When a CW or CCW output is set to
1 or ON, the respective relay wilI be energized and the actuator will
rotate in that direction. The actuator will rotate until that output is set
to 0 or OFF, or until the actuator reaches the end of travel (0° or 90°)
limit switch.
