INSTALLATION
A. Location
The location or placement of the paddle switch must first be determined. The location should be se-
lected such that the product to be monitored is allowed to freely flow both into and away from the rotat-
ing paddle. However, the paddle should not be placed directly under the free-falling path of the product.
Shaft misalignment or paddle vane damage could occur as a result of direct impact or loading from the
product. If the location of the paddle must be very close to the free falling path of product, then the use
of protective baffles is recommended.
B. Surface Preparation
The mounting surface must be prepared for paddle switch installation. The switch can be installed in
two ways. The first method (standard) is to utilize a circular mounting flange that is shipped with the
unit. To use the flange, the mounting bolt pattern of the flange must be transferred to the installation
location on the bin wall and then drilled and tapped for ¼-20 bolts. Centered, within the bolt circle, a 5-
1/2" diameter opening must be cut out of the bin wall to allow for clear passage of the paddle. See be-
low an illustration of the required surface preparation.
The other option for mounting the paddle switch is to use only the threaded portion of the lower head
assembly. To do this, the mounting flange is discarded and a 1-1/4" female NPT threaded section shall
be provided. Ensure bin wall thickness is a minimum (1/4"), then tap for the 1-1/4" NPT threads
(coupling is not required). If the bin wall is too thin to drill and tap, then a pipe coupling must be used. A
hole large enough to accept the OD of the coupling must be drilled or cut into the wall and the coupling
is then welded in place.
