UNPACKING INSTRUCTIONS
The M185 consists of three or four loose items, depending
upon the style of magnet assembly supplied. These items
are packed inside the NEMA 12 type enclosure.
Style 1:
1. Magnet assembly (plastic)
2. Adjustable fastener
3. Band material
Style 2:
1. Magnet assembly (metal)
2. Magnet retainer
3. Adjustable fastener
4. Band material
MAGNET ASSEMBLY INSTALLATION
If a plastic magnet assembly is being installed, then pass
the band material through the slots of the plastic magnet
assembly so the band is routed under the magnet base.
In the case of the metal magnet assembly, insert the
magnet assembly through the center hole of the magnet
retainer. Pass the band material through the slots in the
magnet retainer so the band passes under the magnet.
Adjust the adjustable fastener so roughly 1-1/2 inch of
the adjustable strap material extends past the adjusting
device. Hook one end of the adjustable fastener strap in
the end rectangular cutout of the band material.
Temporarily position the band around the shaft so it
fits flush against the outer diameter. Select the closest
rectangular cutout for the other end of the adjustable
fastener. Cut and discard excess band material. Remove
the band from the shaft and separate the adjustable
fastener. Hook the loose end of the adjustable fastener in
the last band cutout.
Position the band and magnet assembly around the shaft
and select its operational location. Insure that enough
space is allowed for installing the mounting bracket for the
transducer assembly. Verify that the band is perpendicular
to the machine roll axis, and secure by tightening the
adjustable fastener.
TRANSDUCER ASSEMBLY INSTALLATION
The transducer assembly is designed to be mounted within
0.04 to 0.16 inch from the magnet assembly as shown in
the Outline Drawing, Figure 2.
The transducer must be installed in a manner that
will prevent it from moving due to vibration. Excessive
transducer vibration can affect signal accuracy and may
damage the transducer if it comes in contact with the
rotating magnet assembly.
A solid mounting support must be fabricated and
positioned so it is out of the way, preferably under the
shaft, to prevent it from being used as a step or footrest by
machine personnel. This position also has the advantage
of preventing damage to the transducer should the bracket
flex.
The support stand described below is presented only as
an example of how a support can be fabricated. As each
installation is different, the design and fabrication of the
support are left to the individual user.
For heights less than 12 inches, refer to Figure 1. The
support stand can be made of 1-inch pipe and a standard
pipe flange attached to an 8-inch square, 1/4-inch thick
base plate. The transducer
