Mounting kits
For compact/low profile installation - use mounting kit KL01 or KL02. Use with shaft type ”S” only. These
kits allow the user to install it on actuators with a shaft height of 20, 30 or 50mm. The kits also adapt
easily to both 80/30mm actuator top pattern as well as 130/80mm actuator top pattern (see table below
for reference). Standard NAMUR mounting brackets are also available.
The WS/WM Ultraswitch™ 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 fitting to a
NAMUR compliant actuator. These options allow
direct coupling to actuators without couplings,
reducing dead band.
Bolt bracket to actuator and WS/WM
Ultraswitch™ to bracket, leaving bolts finger tight.
For NAMUR applications the WS/WM Ultraswitch™
switch 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 the WS/WM
Ultraswitch™ and actuator. Once the WS/WM
Ultraswitch™ is installed with fasteners loosely
tightened, stroke the actuator two or three times
to align the bracket. Then tighten all fasteners.
Ambient temperature working conditions.
The WS/WM Ultraswitch™ switch box is tested
and operational in following temperature range:
-40° – 180°F
-40° – 80°C
Note! Shaft type ”S”
only!
