Description:
Worcester Controls UltraSwitch™ limit switch enclosures provide local and remote position indication for
automated valves. They generally feature a visual indicator with “red=closed” and “green=open” for intuitive
local position determination. The UltraSwitch™ is available with a number of limit switch options for remote
indication in a variety of electrical applications. They may also be used as a junction box for direct
installation of solenoid valves.
Installation:
UltraSwitches may be installed to valves or valve actuators with a variety of mounting hardware. For best
results, specify the NAMUR shaft option and NAMUR mounting hardware when installing to NAMUR
compliant actuator. These options allow direct coupling to actuators
without couplings, reducing dead band.
Simply bolt bracket to actuator and UltraSwitch™ to bracket, leaving bolts finger tight. For NAMUR applications
the UltraSwitch™ shaft features an integral alignment pin. This pin must engage the tapped hole in the actuator
shaft. For non-NAMUR applications, make
sure to properly install a coupler between UltraSwitch™ and actuator. Once the UltraSwitch™ is installed with
fasteners loosely tightened, stroke the actuator two or three times to align the bracket. Then tighten all fasteners.
Wiring Instructions:
UltraSwitch™ enclosures feature pre-wired switches. All user connections are made at a numbered terminal
strip. Both external bonding and internal grounding locations have been provided for use in installation. A
wiring diagram is located inside the cover and indicates which terminal numbers correspond to switch
contacts: normally open, normally closed, common, etc. Simply follow the wiring diagram and electric code to
connect switches to your system.
For field wiring: ensure that any excess wire lengths or loops are routed away from any moving parts and are
short enough, or secured to ensure a ¼” clearance between the wire and the inside surface of the switchbox
cover.
Note: for all magnetically tripped proximity switches, the top switch (top and third switches for 4-switch
versions) should only be used to indicate the clockwise position: the bottom switch (second and fourth
switches for 4-switch versions) should only be used to indicate the counter-clockwise position. Any deviation
from these settings may result in erratic indication.
Solenoids may also be wired through the UltraSwitch™ enclosure. At least two auxiliary terminals are included as
standard.
