39 Actuators with AS Interface
Installation, Operation and Maintenance Instructions
DESCRIPTION
Worcester/McCANNA Access I Series 39 actuators are pneumatic
quarter-turn valve actuators with solenoid and limit switches or
Namur Proximity Sensors integral to the actuator end cap. The design
utilizes a double-rack, single-pinion concept, with each rack integrally
cast to a piston. Both pistons are supported and centered by large,
stainless steel guide rods. In double-acting units, both pistons are
pressurized on both strokes of the actuator. Ambient temperature
range of the Access unit is 0°F to 160°F.
Standard units feature an extended top shaft for manual override
capabilities and a completely modular design which allows simple
attachment of a variety of accessories. The units feature a control
block (with spool valve) which properly directs supply air to the
actuator. The control block provides independently adjustable speed
control for both opening and closing strokes of the actuator on
double-acting units, and for the closing stroke on spring return units
(standard mounting configuration).
The ASI, or Actuator Sensor Interface, feature of this equipment
permits simple two-wire connection and communication as either a
digital stand-alone device on an ASI network or as an additional
device to the more common digital protocol networks via the
appropriate “gateway”. Solenoid power, actuator opening, actuator
closing and electronic position indication are all accomplished via this
two-wire connection. Integral Light Emitting Diodes (LEDs) display
the status of all inputs and outputs.
The ASI Board has one Output and three Inputs:
The output is used to control the solenoid. When the output (Bit
Ø) is set to 1, the solenoid will be energized. When the output is
set to 0, the solenoid will be de-energized.
Input 1 (Bit 1) is used to monitor whether a fault exists with the
solenoid output (short or open).
Input 2 (Bit 2) is used to monitor whether the switch/Namur
proximity sensor to which it is connected is closed. A 1 indicates
the switch/sensor is closed and a 0 indicates the switch/sensor is
open. Input 2 is normally used to indicate the full clockwise (CW)
or closed end of travel (Switch 2).
Input 3 (Bit 3) is used to monitor whether the switch/Namur
proximity sensor to which it is connected is closed. A 1 indicates
the switch/sensor is closed and a 0 indicates the switch/sensor is
open. Input 3 is normally used to indicate the full counter-
clockwise (CCW) or open end of travel (Switch 1).
a WARNING: SERIES 39 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, 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.
CAUTIONS: When actuator is installed in outdoor conditions,
water can enter the exhaust hole(s) of the control block and
then freeze. Flowserve suggests a cover be used, or mount
the actuator such that the block exhaust hole(s) will not fill
with water.
Flowserve recommends that all products, which 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.
IMPORTANT: INCLUDED IN ALL 39 ACTUATOR ACCESSORY AND
REPAIR KITS IS A REBUILD/ACCESSORY ADDITION LABEL,
WHICH IS TO BE MARKED WITH A PERMANENT MARKER AND
THEN APPLIED TO THE ACTUATOR AFTER AN ACCESSORY KIT
HAS BEEN INSTALLED OR AN ACTUATOR HAS BEEN REPAIRED.
INSTALLATION
NOTE: The Series 39 actuator is normally installed with its major axis
parallel to the pipeline. This is mandatory when mounting actuator to
90° V1 diverter/three-way (D44 and T44) valves and CPT valves. The
actuator can be oriented above, beside or beneath the valve without
affecting its operation.
