About these
operating
instructions
All of the information herein is the exclusive proprietary property
of Maxcess International, and is disclosed with the understanding
that it will be retained in confidence and will neither be duplicated
nor copied in whole or in part nor be used for any purpose other
than for which disclosed.
Copyright 2016, all rights reserved.
Periodically there will be updates to this manual. The latest
version is available on our website or by calling the number on
the back page of this publication.
These load cell devices must not be installed or used in a machine
or system which does not comply with the machinery directive
2006/42/EC.
These load cell devices were designed and manufactured to be
installed as Partly Completed Machinery into a machine or partly
completed machine.
The instructions must be read and used by all persons who have
the responsibility of installing and maintaining these load cell
devices.
These instructions must be retained and incorporated in the
technical documentation for the machine or partly completed
machinery into which the load cell device is installed.
Language
These are the original instructions, written in English.

INTRODUCTION
www.maxcessintl.com MAGPOWR CL Load Cells MI 850A192 J 1
CE marking
Only the 2006/42/EC Machinery directive applies to these devices
and they are not marked with the CE sign.
Electromagnetic Compatibility (EMC)
The load cell device is inherently benign in terms of
electromagnetic compatibility and the EMC directive has not been
applied. The electromagnetic compatibility of the load cell device
can only be assessed in connection with the entire electrical
installation including the control. The machine builder who
installs this partly completed machinery into a machine is
responsible for compliance with the EMC directive.
Conventions used
All dimensions and specifications are shown in the format
millimeters [inches] unless otherwise specified.
Product overview
The model CL load cell is designed to be mounted on the vertical
face of a machine side frame and to incorporate the customer’s
cantilever shaft and roll assembly. The CL load cell can be
mounted on either the inside or outside of the machine side
frame as shown in Figure 1 . The CL load cells are compatible with
all MAGPOWR tension readouts and controls.
Theory of operation
The load cell construction consists of a beam with a metal foil
strain gage bonded at the bending point of the beam. The spring
constant of the beam causes the beam to deflect with the applied
force. The beam deflection causes the strain in the metal below
the strain gage to vary linearly with the applied force. The strain
gage converts the induced strain into an electrical signal which is
proportional to the induced strain.

Mechanical and
electrical installation
CAUTION –Possible damage to load cell.
Do not hammer on the load cell.
CAUTION –Possible damage to load cell.
Do not disassemble the load cell; there are no serviceable parts
inside.
WARNING –Danger of injury from crushing.
Maintenance and repair tasks on the load cell device must be
performed only when the machine has been stopped and has
been secured from being turned on again.
Mounting
1. Remove the envelope containing 4 set screws from the bore
and install into sensor as shown in Figure 1 .
2. Select a clean flat surface where the wrap angle of the web
does not change.
3. Locate the centerline of the CL load cell mounting holes, so
that it bisects the wrap angle of the web.
4. Fasten with two cap screws making sure the cap screw
penetration does not exceed dimension 'N' shown on the
outline dimension drawing ( page 4-1 ).
Figure 1. Mounting

Mounting continued
The force direction arrow should also bisect the wrap angle of the
web, and point in the same direction as the resultant tension
force as shown in Figure 2.
Figure 2. Resultant force alignment
Wiring
See page 3-2 .
Shaft and roll
assembly
(supplied by customer)
1. Insert the customer’s shaft and roll assembly into the CL
Load Cell as shown in Figure 1; page 5-1 .
2. Make sure that neither the shaft nor the roll will interfere
with the CL load cell housing or the machine side frame.
For outside frame mount, the minimum clearance hole
diameter in the machine side frame is:
CL1 models 17.5 mm [0.69 inch]
CL 2 models 26.9 mm [1.06 inch]
3. Tighten all four set screws securely against the shaft.
4. Connect the CL load cell to the control with shielded cable.
