Incorporated in the design of the PL is a magnetic drive that is time proven by
decades of use in our Mark Series valve position indicator product line. A synchro-
nous motor rotates the paddle utilizing a magnetic drive. As product builds up the
paddle is impeded from moving and the resulting motor torque activates the output
switches and stops the motor. A spring mechanism reactivates the motor and returns
the switches to normal state when the product no longer impedes the paddle rota-
tion. Weatherproof models include a bright red ED switch status indication light.
Standard construction is weatherproof with explosion-proof optional, and the unit can
be side or top mounted. A high temperature option is available for use with media up
to 500°F (260°C). The P S is designed with the industry standard 1-1/4˝ male NPT
connection and mounting flanges.
FEATURE
•Magnetic drive that isolates and completely seals the control head from the
process and environment preventing material or dust from entering the control
head.
•Motor shuts-off when paddle stalls increasing motor life, preventing motor
burnout, and decreasing power usage.
•lip clutch design enabled by the magnetic drive that prevents damage to motor
and drive mechanism from sudden or excessive loading on the paddle.
•tatus indication light on weatherproof models. ight is on the side of the enclo-
sure making it easy to view.
•crew cover on the enclosure for easy access with no worries about losing bolts
or screws.
•Modular design to allow field installation of any paddle, flanges, shaft extensions,
or shaft guards.
•Flexible coupling available for protection of the paddle and drive from side loads,
surges or impacts. Recommended for top mount applications with shaft extension
and applications with large or heavy materials.

Mounting Location
Select a location where the paddle is out of the direct flow of media/material, and
where media does not accumulate permanently. It may be necessary to protect the
paddle with a protective shield or baffle protection.
Protection provided by the equipment may be impaired if the equipment is used with
accessories not provided or recommended by Proximity, or is used in a manner not
specified by Proximity.
Mounting Accessories
Shaft Extensions and Flexible Shaft/Coupling
A standard paddle extension is supplied with all controls that is used to connect the
stub shaft of the control head to a paddle or to an extension shaft constructed of 1/4˝
pipe. Shaft extensions may be purchased from Proximity Controls in carbon steel and
stainless steel. Shaft extensions may also be constructed from 1/4˝ pipe, which is
threaded with 1/4˝ male NPT connections on both ends. Drill .152˝ diameter holes
through the pipe at a distance of .170˝ from each end. These holes should accept a
1/8˝ diameter roll pin. Shaft extensions should not exceed 48˝ in length. Multiple cou-
plings may be connected using coupling model number CP -1.
Note: All joints should be secured with the 1/8˝ diameter roll pins supplied. Care
should be taken to press pins flush without damaging the bearings of the control.
A flexible shaft/coupling, model number CP -F X, may be substituted for the stan-
dard extension. The flexible coupling helps protect the control by absorbing side load-
ing, heavy loading, or loading caused by material surges. It is also recommended for
top mount applications when shaft extensions are used.
Shaft Shields
Shaft shields are recommended for use with shaft lengths over 12˝ to protect the shaft
from side loading. Shaft shields are available from Proximity Controls in carbon steel
and stainless steel. Shields may also be constructed from 1-1/4˝ pipe, which is
threaded with a 1-1/4˝ male NPT connection on one end. Shield pipe should be cut to
cover the shaft length while allowing sufficient clearance between the paddle and bot-
tom of shield. The shaft shield should be securely threaded into a full coupling weld-
ed to the bin or a full coupling mounting flange attached to the bin. Shaft should not
contact the inside diameter of the shaft shield.
Mounting Procedure
Mounting without a Flange
Paddles PD -1 and PD -3 will fit through a 1-1/4˝ coupling making a mounting flange
unnecessary. A mounting flange may also be avoided for applications where there is
access to the inside of the bin to attach the paddle from the inside once the switch
control head is installed.
ocate the desired mounting point and cut a hole in the bin of the proper diameter to
insert a 1-1/4˝ pipe coupling. For mounting without a shaft shield weld a 1-1/4˝ half
pipe coupling to the bin wall so that the coupling is flush with the interior wall. For
mounting with a shaft shield weld a 1-1/4˝ full coupling so that the coupling is halfway
into the bin. If using a PD -1 or PD -3 attach the paddle to the switch control head,
if not already connected, by screwing into the 1/4˝ NPT connection on the shaft and
inserting the roll pin. Attach the switch control head to the pipe coupling buy inserting
the paddle through the coupling and screwing in. If attaching the paddle from the
inside then first attach the switch to the coupling and then attach the paddle from the
inside of the bin as described above.
Mounting with a Flange
Paddles PD -2 and PD -4 will require flange mounting if the interior of the bin is not
accessible. Half coupling flanges (Models F G-CSH and F G-SH) should be used on
installations not requiring a shaft guard. Full coupling mounting flanges (Models F G-
CSF and F G-SSF) should be used with installations requiring a shaft guard.
If the mounting flange is used on a flat surface, layout a 7˝ bolt circle. The flange is
designed with clearance holes for 1/4˝ bolts or screws. Drill and tap 6 holes equally
spaced, on the bolt circle, of the appropriate thread type. At the center cut a hole of
sufficient clearance diameter to allow insertion of the paddle selected. It may be nec-
essary to tack weld bolts or screws to the flange or inner surface of the bin. On bins
with curved surfaces it may be necessary to create a template, which will follow the
contour of the bin wall, in order to locate the hole positions. Use the gasket supplied
if required between the bin wall and flange.

General
If a control is mounted on the side wall of a bin, the conduit entry should be directed
downwards. Also there should be ample clearance for cover removal. Paddles are
secured to the extensions with a 1/4˝ NPT and 1/8˝ diameter roll pin. Care should be
taken to press pins flush without damaging the bearings of the control.
Electrical
Make electrical connections per the wiring diagram for output switch options select-
ed. Wire in accordance with local codes. For hazardous locations, a sealing fitting
must be located within 18˝ of the control.
Wiring
An external switch or circuit breaker should be added to during the installation as a
disconnecting device. The switch or circuit breaker must meet the requirements of
IEC 60947-1 and IEC 60947-3, shall disconnect all current carrying conductors, and
shall not interrupt the protective earth ground. The disconnecting switch or circuit
breaker must be marked or labeled with the symbols “I” for on and “O” for off, per IEC
60417-5007 & IEC 60417-5008 and shall be marked as “Disconnecting Device”. Do
not position the P S in a space where it is difficult to operate the disconnecting device
that provides power. 300V @ 105°C 18 AWG/0.75 mm2wiring with PVC or equivalent
insulation with 94-V0 or FV-0 flammability rating is recommended for the switch out-
puts and power.
As a permanently installed piece of equipment, a power disconnect
switch, circuit breaker, or other approved disconnect device must be
installed in close proximity to the installed board and within easy reach
of the operator. This disconnect device must include a label indicating
its function as a mains disconnect. A 15amp circuit breaker or fuse
device is recommended.
Time Delay
With the DIP position 1 set to “off” the delay is upon energizing of the relay, and with
it set to “on” the delay is upon de-energizing of the relay. Select delay range wanted
from the chart and set the dip switches to the appropriate positions. Then adjust the
one-turn (360˚) potentiometer for the exact time interval required within the selected
delay range. Example: If a 5 minute delay is required, set DIP switches to 0-7 minute
position. Then use potentiometer to adjust to 5 minute period.
MAINTENANCE
Upon final installation of the Series P S Paddle evel Switch, no routine maintenance
is required. A periodic check of system calibration is recommended. The Series P S
is not field serviceable and should be returned if repair is needed (field repair should
not be attempted and may void warranty). Be sure to include a brief description of the
problem plus any relevant application notes. Contact customer service to receive a
return goods authorization number before shipping.
