Introduction
This service manual provides information
required for installing, wiring, and maintaining
Warner Electric Magnetic Particle clutches and
brakes. Dimensions and specifications are also
included. The models covered in this service
manual include POC and PHC-R clutches and
POB and PTB brakes. For selection information,
please refer to your Warner Electric Tension
Control Sytems Catalog.
Warner Electric Magnetic Particle clutches and
brakes provide smooth and controllable torque
for a variety of torque and tension control applications. They also provide excellent performance for cycling and positioning applications.
Quick response is achieved by applying full
rated voltage. Lower voltage can be applied for
softer engagements. Extremely accurate tension
control can be achieved with an appropriate
Warner Electric tension control for electric
brakes and clutches.
Failure to follow these
instructions may result in product damage,
equipment damage, and serious or fatal
injury to personnel.
Make sure all power is turned
off to this equipment when installing, as
injury (or even death) may result from contact
with live wires or rotating shafts.

Installation Instructions
Introduction
Verify the model of your clutch or brake by
checking the label before proceeding with these
instructions. POC and PHC-R designate clutch
models and POB and PTB are brakes. All models of POC clutches are face mounted (except
size 80, which is foot mounted) and have male
input and output shafts. See Figures 1 and 2.
The PHC-R clutch is designed to be shaft
mounted and is ideal for "parallel shaft" applications. It has a hollow bore and slides on the output shaft. An input hub with flange is provided
for mounting a pulley or sprocket. An integral
fan rotates with the input for additional cooling.
See Figure 3.
POB and PTB-BL3 brakes are face mounted
with male input shafts. Like the POC's, only the
size 80 is foot mounted. The major difference
between PTB-BL3 and POB brakes is that PTBBL3's utilize a patented heat pipe cooling
method that provides heat dissipation several
times greater than conventional cooling. See
Figures 4, 5, and 6 for mounting information on
POB's and PTB-BL3's.
Pre-Mounting
Note: Unit performance can be affected by
prolonged exposure to humid environments.
Please store in a dry location.
Note: The equipment covered by this service
manual must be installed in accordance with
these instructions. Failure to do so may damage the equipment and void the warranty.
1. Remove the Magnetic Particle unit from its
shipping carton and inspect it thoroughly to
ensure that it has arrived in good condition.
When handling, please take care not to damage the unit’s lead wires or terminal block.
2. Check the input shaft/hub to make sure it
can be rotated by hand. On clutch assemblies, hold the output stationary while turning
the input. The powder inside the unit may
settle due to shock and vibration incurred
during shipping, making rotation difficult. This
is easily remedied by turning the unit upside
down and gently tapping the housing to
loosen the powder. Do not hit shaft. See
page 10 for nominal drag torque values.
3. Make sure the location chosen for mounting
will not expose the unit to water or oil. If
water or oil enters the powder cavity, performance may be affected. If the unit is
mounted next to a gearbox, special care
should be taken to prevent oil from working
its way into the unit.
4. If couplings are to be used in the drive system, the mounting surface must properly
locate the housing to ensure alignment is
within coupling tolerances.
5. When connections are made with pulleys or
sprockets, the overhung load must be verified to be within rating. See page 8 for allowable overhung load information.
Mounting
Note: Do not use excessive force when mount-
ing couplings, pulleys, or sprockets on shafts.
Note: For proper function, magnetic particle
units must be mounted so the shaft is horizontal.
Use the proper mounting method described for
the model being installed.

POC Clutches
For mounting dimensions, see pages 12-13 of
this service manual.
Step 1: Bolt Clutch in Place
Mount the clutch to a vertical surface, using
customer supplied fasteners. For models larger
than size 5, the housing must be secured on
both input and output sides. See Figure 1. A flat
horizontal mounting surface is required for foot
mounted size 80 clutches. See Figure 2.
Step 2: Make Mechanical Connections
Mount couplings, pulleys, or sprockets to the
male shafts per the manufacturers' recommendations. The pulleys, sprockets, and couplings
are customer supplied.
PHC-R Clutches
For mounting dimensions, please refer to page
11 of this service manual.
Step 1: Secure Clutch to Shaft
Slide the clutch on the shaft that is being driven
by the clutch. Secure the clutch with customer
supplied locking collars or other suitable means.
(Mounting the clutch on the shaft that is driving
the clutch is acceptable, but doing so increases
total load inertia.)
Step 2: Attach Antirotation Restraint
Since this is a shaft mounted unit with a stationary field supported by bearings, the field must
be restrained to prevent bearing drag from
pulling on the lead wires. Restraining device
must not preload the bearing.
The field can be restrained with a holding arm
attached to the tapped holes in the field housing
or with capscrews through a mounting bracket
as shown in Figure 3. If bolts are used, first
hand tighten the bolt just enough to take out the
clearance under the head of the capscrew. Then
tighten the locking nut while preventing the bolt
from turning.

Electrical Connections
To avoid injury (or even death),
always make certain all power is off before
attempting to install or service the control or
any electrical equipment.
The clutch and brakes operate on DC voltage.
Warner Electric offers a full line of AC powered
controls to meet the needs of almost every
application. The service and installation instructions included with each Warner Electric control
show the proper electrical connections for the
units. Do not use the varistor supplied with the
unit if you are using a Warner Electric control.
Warner Electric controls have built in suppression.
Each PTB-BL3 brake has a cooling fan and a
thermal switch. Connect these items according
to Figure 7.
Use appropriate terminal connectors when
wiring to the terminal block. After connecting the
terminal, cover it with the attached rubber cap
so that no bare wire is exposed.
After wiring your Magnetic Particle clutch or
brake, confirm that the control circuit is functioning. Without rotating the input shaft, check
for voltage at the unit when the control output is
turned on. If appropriate, set the current for the
proper output. Your magnetic particle unit is
now ready for operation. For additional information on start up and maintenance, see page 9 of
this manual.
PTB-BL3 Wiring
The PTB-BL3 units are offered with a normally
closed thermal switch. This switch can be used
to protect the unit from overheating. It is not
recommended that this switch be connected in
series with the unit, because the opening of the
thermal switch on the output side of the control
may damage the control.
Figure 7 shows one possible way of using the
switch in a shutdown circuit. Under normal
operation, when power is applied to the circuit,
voltage is applied to the interval-on-relay, K
S
.
This momentarily closes contacts K
SA
. This in
turn applies voltage to relay K
T
. This double pole
double throw relay closes contacts K
TA1
, and
K
TB1
and opens contacts K
TA2
and K
TB2
. These
contacts will remain in this state unless power is
removed or the thermal switch opens. If the
switch opens, the thermal shutdown indicator
will be activated and the state of K
TB1
and /or
K
TB2
will shut down the system. After correcting
the cause of the thermal shutdown, the thermal
reset button will reset the shutdown circuit and
power up the system.

Overhung Load Data
Note: Shaft extensions are not recommended.
When an overhung load (side load) is applied to
the shaft, verify that this load does not exceed
the maximum allowable. You will need to know
your operating speed and where your load is
applied to the shaft (See dimension 'A', Figure
8). For your speed, determine the speed coefficient from the coefficient table. Also, determine
the allowable overhung load from the chart
based on dimension 'A'. Multiply the load from
the chart times the speed coefficient to determine the allowable load for your application.

Note: This table is based on 1000 rpm and
6000 hours bearing life. Also, this table
assumes that no thrust load is applied.
For most applications, the overhung load is
caused by pulleys or sprockets. The smaller the
pitch diameter (P.D.) of the pulley or sprocket,
the higher the belt tension, and therefore the
higher the overhung load. To determine the minimum pulley diameter for your application, use
the following equation:
Min. P.D.(in.) = 24 T K
C R
T - Torque (lb. ft.) This is the torque actually
being transmitted, not necessarily the maximum
torque capacity of the unit.
K - Safety factor for the tension in the type of
drive.
Use: 1.2 to 1.5 for sprockets
2 to 4 for belts
C - Speed coefficient from table.
R - Allowable Overhung Load from table.
Example: Determine the minimum sprocket
diameter that can be used on a POB-5.
Dimension A is 1.11 inches, required torque is
20 lb. ft. and the speed is 600 RPM.
Min. P.D.(in.) = 24 x 20 x 1.5
1.2 x 136
= 4.4 inch minimum P.D.

Start Up
The powder in magnetic particle units sometimes settles during shipping and will need to be
redistributed. A simple run in procedure should
be performed to ensure proper performance.
Run in Procedure
Notes: 1. Before running in the unit, make
sure it does not bind. See step 2
(Page 3) of the Premounting instructions.
2. For clutches, the output must be
secured properly to prevent turning
if full torque is accidentally applied.
Set the control output voltage for 5 to 6 volts.
Turn off the control and run the input for one
minute. Then run the input at a speed close to,
but not exceeding, 1000 RPM. Cycle the unit at
5 or 6 volts for five seconds on and ten seconds
off. Repeat for 20 cycles.
When the powder is redistributed properly, the
torque will be consistent and proportional to
current.
Maintenance
Heat
Overheating occurs when the heat generated
exceeds the heat dissipation of the unit. Please
refer to the following table for maximum allowable surface temperatures.
Slip Applications
The heat generated is proportional to torque and
slip rpm. Care must be taken when adjusting
torque on the control to make sure that unit heat
dissipation capacity is not exceeded. Refer to
the sizing procedure in the catalog to make sure
the unit has adequate heat dissipation capability. Do not increase slip speed or torque without
verifying that the unit can dissipate the heat
generated.
Cycling Applications
In cycling applications, the speed and inertia of
the load and the frequency of starting and stopping determines the heat generated. Refer to the
selection procedure in the catalog to verify that
the unit can handle the thermal energy generated in your application. Do not increase the input
speed, cycle rate, or inertia without checking the
units ability to dissipate the heat generated.
