INTENDED USERS

This Instruction Manual is to be made available to all persons who are required to configure, install or service the
equipment described in this manual or any other related activity.

ADDITIONAL INFORMATION

ATTENTION: The following information is provided merely as a guide for proper installation. Cleveland Motion
Controls cannot assume responsibility for the compliance (or failure to comply) to any code (national, local or other)
that prescribes the proper installation of this electro-mechanical device or associated equipment. A hazard of
personal injury and/or property damage can exist if applicable codes are not adhered to.

CE EMC RESPONSIBILITY

The Cleveland-Kidder Ultra Transducer may be used by a manufacturer as a component of a larger system, along
with other components, which may or may not bear the CE mark. The system assembler is responsible for the
compliance of the system as a whole with the EMC Directive.

Before installing the Transducer you must clearly understand who is legally responsible for conformance with the
EMC Directive. Misappropriation of the CE mark is a criminal offense.

1 IMPORTANT INFORMATION

1.1 ORDER NUMBERS

Use the following example and Tables A to determine order numbers for:

• Ultra Series Under Pillow Block Transducers

• With or without mounting Plate

Figure 1 – Example for Determining Transducer Order Numbers

If you needed to Purchase a Transducer corresponding to
following description:

• Size 1 Under Pillow Block Transducer.

• With Blank mounting plate.

• Maximum Working Force (MWF) of 100 lbs.

Then, you would use Catalog Numbers:

Ultra Series Transducer = M846-13523-100 (Refer to
Table A)

Having the following information at hand will help you to easily determine which of the Ultra Series Under P illow
Block Transducers is right for your application:

• The size of the pillow block bearing used

• Pillow block mounting plate requirements

• Maximum wor k in g for c e

Use Table A to determine the catalog number for the proper Under Pillow Block Transducer.

Table A – Determining a Catalog Number for the Ultra Under Pillow Block Transducer with Stainless Steel mounting plate.

Order Code Suffix, M.W.F.

Size Base Part Number

-000 -100 -200 -300 -400 -500

UPB1 M846-13523 25 lb. 50 lb. 100 lb. 250 lb. 500 l b. 1000 lb.

UPB2 M846-13510 1000 lb. 2500 lb. 5000 lb. 10000 lb. 20000 lb.

For units without the blank Stainless Steel mounting plate, change the last digit of the ending suffix from a zero “0”
to a “1”. Example: use M846-13523-001 instead of M846-13523-000

Disassembly by improperly trained personnel may result in additi onal damage to t hese units. Should repairs
be required or for warranty repairs, contact the Customer Service Department for a return authorization
number before returning the units.

1.3 RECEIVING AND UNPACKING

After receiving the Ultra Under Pillow Block Transducer you should:

• Carefully, unpack and inspect the equipment

• Compare the received shipment with the packing list

• Report any damage to the carrier and your CMC representative

• Store equipment that will not be used in a clean, dry location

• Take appropriate precautions to prevent moisture, dust and dirt from accumulating in storage and

installation areas

1.4 PRE-INSTALLATION PRECAUTIONS

1.4.1 SHIPPING

Shock and the vibration transmitted to the transducers by the sensing roll during transpor tation can damage the
transducers. It is essential that you remove the sensing roll when the machine is shipped with the transducers
mounted.

1.4.2 ROLL BALANCE

The sensing roll should be adequately balanced. Understand that the balance of the sensing roll will be more
demanding than that typically needed in general rotating machinery. The goal goes beyond just limiting the force to
which bearings will be subjected, but rather to minimize the generation of an unintended noise component in the
transducer tension signal. The centrifugal force caused by imbalance can be estimated using the following formula:

F = (1.77 x 10

Where:

F = centrifugal force (in units of lb-f)
W = weight imbalance (in units of ounces)
R = radius of displacement, distance of imbalance weight from roll axis of rotation (in inches)
RPM = Revolution per minute

The force increase is equal to the square of the RPM, or in other words, doubling the RPM causes four times the
imbalance force. Because rolls tend to have a high length-to-diameter ratio, two-plane (dynamic) balancing is
recommended. Balancing is particularly needed where higher RPMs and lower web forces are involved.

To illustrate how much imbalance induced “noise” could be generated, the following table shows the force
disturbance for various ISO balance grades for an illustrative case of a 20 pound roll (4” diameter x 36” long,
aluminum ) rotating at 1500 RPM.

Balance Grade
(ISO 1940/1)

G16 1.25 oz-in +/- 5 lb-f at 25 Hz
G6.3 0.5 oz-in +/- 2 lb-f at 25 Hz

G2.5 0.2 oz-in +/- 0.8 lb-f at 25 Hz
G1 0.08 oz-in +/- 0.3 lb-f at 25 Hz
