Worcester Controls/McCANNA ACCESS M/AS-Interface is an add-on
accessory to the Series 39 pneumatic quarter-turn valve actuator. The
ACCESS M package adds a single housing to the actuator which
contains limit switches or Namur proximity sensors and integral
solenoid. The Series 39 actuator utilizes a double-rack, single-pinion
concept, with each rack integrally affixed 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.
Standard actuators feature an extended top shaft for manual override
capabilities and a completely modular design which allows simple
attachment of a variety of accessories. The ACCESS M unit features 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).
