PB-500 Primary Brake Normal
Duty Pin Drive Armature
Installation Instructions
A. Installing the Conduit Box
Please follow instructions supplied with conduit box.
B. Mounting the Magnet
The brake magnet is mounted to a stationary machine
member by a flange. Extreme care must be taken in
selecting the location for the mounting of the magnet.
Proper positioning is very important for the unit to function
correctly.
1. A pilot diameter on the mounting surface is essential
to hold the magnet within the required tolerances.
(Figure 1)
2. A machined pilot diameter is provided on the magnet
mounting flange (refer to illustrations) to aid in the
proper positioning of the magnet.
3. Once the mounting surface has been prepared,
the magnet is bolted in place with capscrews and
lock-washers. (Figure 2)
Figure 1
Figure 2
Figure 3
C. Assembling the Armature Hub
Assemble the armature to the armature hub with the
autogap mounting accessory. Refer to Figure 4. The hub
is reversible. The side on which the armature is mounted
will depend on the direction in which the taperlock bushing
must enter.
The autogap assembly is a double spring device which
allows for automatic armature clearance and adjustment
for wear. The smaller or conical spring pushes the armature
from the rotor face, leaving the gap of about 1/32 inch,
while the straight spring automatically follows up for
wear. This combination maintains maximum performance
efficiency throughout the life of the unit.
4. Use a dial indicator to check the unit for concentric-
ity and squareness to the shaft. The unit should be
concentric within .010 T.I.R. and square within .006
T.I.R. (Figure 3)

4. Securely fasten the armature assembly to the shaft
by alternately tightening each setscrew. During the
tightening process, the bushing should be tapped
lightly to make certain it seats-in properly.
Step 4
Insert assembled drive pins through armature hub and
straight springs and into the threaded armature bosses.
Apply grade “AA” Loctite Sealant on drive pin threads.
(Figure 8)
Step 5
Tighten drive pins until shoulders of pins are against
face of armature bosses. Since threads are class No. 3
fit, pins may seem to bind.
Step 6
Compress the retainers against the armature hub and
check to see that the armature hub is held tightly to the
armature bosses.
Note: This position must not be disturbed during
completion of assembly. (Figure 9)
Figure 9
Figure 8
Figure 10
D. Mounting the Armature Assembly
The armature and armature hub are mounted on the
shaft with a taperlock bushing. All parts must be clean
and free from burrs and chips before assembling.
1. Place the bushing into the hub and insert the key.
The key is a side-to-side fit and should not contact
the top of the keyway.
2. Insert the locking setscrews into the bushing and
slide the assembly onto the shaft.
3. Place the face of the armature approximately 1/32”
from the face of the magnet. Once this gap is set, it
will be automatically maintained throughout the life of
the unit. (Figure 10)

C. Assembling the Armature and Hub
Scan to watch!
Setting the Autogap for a Heavy Duty Clutch Coupling
or Brake in sizes 500 & 650
https://p.widencdn.net/mqwdke/V-0100-WE
The heavy duty units contain spline drive armatures and
hubs. The armatures are shipped with a built-in autogap
spring accessory. This device automatically maintains a
gap of about 1/32” between the armature and magnet
faces for the life of the unit.
Follow these instructions to assemble the armature and
splined hub.
Step 1
Place the splined hub on a flat surface. The extended
portion of the hub, where the set screw holes are locat-
ed, should be down.
Step 2
Check the detent ring in the armature assembly to
make sure it is centered evenly around the spline. This
ring moves freely, but it should be centered for easier
assembly of the hub.
Step 3
Holding the armature with the segmented side up, press
the armature onto the splined hub. This is most easily
done by applying firm back-and-forth pressure. (Figure
4)
Step 4
Push the assembly up against the retainer ring.
Figure 4
Figure 5
D. Mounting the Armature-Hub Assembly
1. Slide the armature-hub assembly onto the shaft
until the armature face touches the magnet face.
2. Move the assembly back to allow a gap of about
1/16” between the two faces.
3. Secure the armature-hub assembly in this posi-
tion by tightening the two setscrews in the hub.
4. Check the assembly by pressing the armature
into contact with the magnet face and then
releasing it. The armature should spring back
about 1/32”. This gap will be automatically main-
tained throughout the life of the unit. (Figure 5)

Conduit Box
Installation Instructions
Conduit Box Kit No. 5200-101-010 contains all com-
ponents needed to assemble a conduit box for PB500
and PB650 brake.
When properly installed, this conduit box is designed
to provide a proper means for field wiring termina-
tions. It conforms to the requirements of Underwriters
Laboratories.
Do not connect rigid conduit
directly to the conduit box. A minimum of
12” of flexible liquid tight conduit or other
suitable flexible wiring with appropriate
fittings is required. Flexible wiring is required
to prevent side loading of bearing on bearing
mounted clutches and possible deformation
or breakage of the conduit box or clutch/
brake components during assembly.
Step 1
Assemble a customer supplied flexible wiring connector
into desired end of conduit box (3). Press protective
plug (5) into unused conduit hole.
Thread green washer head hex screw (9) into round
hole in base of conduit box. Place terminal ring (9-1)
over screw before inserting.
Snap two wire grommets (6) into square holes in con-
duit box base. The grommet crowns should be toward
the outside of the box and the rubber flanges should
be on both sides of the conduit box.
Push two terminal spacers (7) through rubber grom-
mets using the correct terminal spacers. (See Figure
10)

Step 2
Fasten bracket (1) to clutch field/brake magnet with
one No. 10-32 hex washer head screw (2). The screw
is self-tapping, threads are not provided in the magnet
bracket adapter. The square projection on the magnet
fits into the square hole in the bracket. The curved side
of the bracket mounts toward the magnet. The bracket
flange is toward the flange side of the magnet. (See
Figure 11)
Step 3
Mount conduit box to bracket. The conduit box flange
must be toward flange side or the magnet (rear of
bracket). Thread terminal spacers into field/magnet
before fastening conduit box to bracket. Do not over
tighten, excessive torque will pull thread insert out of
magnet/field. Secure conduit box to bracket with two
No. 10-32 hex washer head screws (4). (See Figure 12)
Step 4
Connect electric supply cable to the fitting installed on
the conduit box. If an external power supply is furnish-
ing DC current to the clutch or brake, proceed to Step
5 and skip Step 6. If a Warner Electric CBC-100 power
supply is being installed in the conduit box, skip Step 5
and proceed to Step 6.
Step 5 - DC Connection
Slide one terminal cap (8) onto each of the two supply
conductors, small end first. Connect the two supply
conductors (with rubber caps) to the magnet or field
terminals using two No. 8 brass screws (11) and ring
terminals (9-1). The stripped wires can wrap around the
screw between the terminal ring and the screw head or
other ring type terminals may be used. Electrical supply
connections must conform to local electrical codes.
Install plug (12) into cover hole.
Step 6 - AC Connection
When a CBC-100 power supply is used, refer to instal-
lation sheet P-266-WE provided with the CBC-100, fol-
lowing instructions carefully. To mount the CBC-100 to
the conduit box, place the control into the cover so the
curved surfaces conform, line up the cover hole with
the control mounting hole and fasten with screw pro-
vided in the mounting kit. Connections to the magnet
or field terminals are as outlined in Step 5.
Step 7
A ground wire is recommended for grounding of the
conduit box and brake magnet or clutch field. Connect
this wire with the green ground screw (8) to the hole in
the bottom of the box. Consult electrical local codes
regarding grounding requirements.
Step 8
Install cover (10) by sliding the slot in the cover over
the tab on one end of the conduit box and secure the
cover on the opposite end with one No. 10-32 hex
washer head screw (11).

Burnishing
Intimate metal to metal contact is essential between
the armature and the metal rings (poles) of the magnet
or rotor. Warner Electric clutches and brakes leave the
factory with the friction material slightly undercut to
assure good initial contact.
Normally, the desired wearing-in process occurs nat-
urally as the surfaces slip upon engagement. The time
for wear-in, which is necessary to obtain the ultimate
torque of the unit, will vary depending on speed, load,
or cycle duty.
If maximum torque is required immediately after instal-
lation, the unit should be burnished by slipping the
friction surfaces together at reduced voltage. It is rec-
ommended that the burnishings be done right on the
application, if at all possible.
Burnishing at high speed will result in a smoother
wear-in pattern and reduce the time for burnishing.
The voltage should be set at approximately 30% or
40% of the rated value.
The unit should be cycled on and off to allow sufficient
time between slip cycles to prevent overheating.
When a Warner Electric brake or clutch is properly
assembled and installed, no further servicing, lubrica-
tion, or maintenance should be required throughout
the life of the unit.
Maintenance
Wear Pattern: Wear grooves appear on the armature
and magnet surfaces. This is a normal wear condition,
and does not impair functioning of the unit. Normally,
the magnet and armature, as a mating pair, will wear
at the same rate. It is the usual recommendation that
both components be replaced at the same time.
Remachining the face of a worn armature is not rec-
ommended. If a replacement armature is to be used
with a used magnet, it is necessary to remachine the
worn magnet face. In refacing a magnet: (1) machine
only enough material to clean up the complete face of
the magnet; (2) hold the face within .005” of parallel
with the mounting plate; and (3) undercut the molded
facing material .001” - .003” below the metal poles.
Heat: Excessive heat and high operating temperatures
are causes of rapid wear. Units, therefore, should be
ventilated as efficiently as possible, especially if the
application requires fast, repetitive cycle operation.
Foreign Materials: If units are used on machinery
where fine, abrasive dust, chips or grit are dispelled
into the atmosphere, shielding of the brake may be
necessary if maximum life is to be obtained.
Where units are used near gear boxes or transmis-
sions requiring frequent lubrication, means should be
provided to protect the friction surfaces from oil and
grease to prevent serious loss of torque.
Oil and grease accidently reaching the friction surfac-
es may be removed by wiping with a rag dampened
with a suitable cleaner, which leaves no residue. In
performing this operation, do not drench the friction
material.
If the friction materials have been saturated with oil
or grease, no amount of cleaning will be completely
effective. Once such a unit has been placed back in
service, heat will cause the oil to boil to the surface,
resulting in further torque loss.
Torque Loss: If a brake or clutch slips or loses torque
completely, the initial check should be the input volt-
age to the magnet or field as follows:
90-Volt Series: Connect a DC voltmeter with a range
of 0-100 or more directly across the magnet or field
terminals. With the power on and the potentiometer
turned up, a normal reading is 90 volts, although 85
to 95 is satisfactory. The reading should drop as the
potentiometer control is adjusted counterclockwise.
24-Volt Series: Use a DC voltmeter with a range of
0-30 volts or more. A normal reading is approximately
22-26 volts.
6-Volt Series: Use a DC voltmeter of approximately
0-15 volt range. A normal reading is from 5.5 to 6.5
volts.
The above checks normally are sufficient. Further
checks may be made as follows: a low range amme-
ter, when connected in series with one magnet lead,
will normally indicate approximately .40 amperes for
the 90 volt units, 1.0 ampere for the 24 volt, and 3.5
amperes for the 6 volt series. These readings are with
the power on and the potentiometer control in the
maximum position.
Ohmmeter checks should be made with the power
off and the circuit open (to be certain, disconnect one
lead to the magnet). Average resistance for the 90 volt
series is 220 ohms; for the 24 volt, 20 ohms; and for
the 6 volt series, 1.5 ohms. A very high or infinite resis-
tance reading would indicate an open coil.
If the above checks indicate that the proper voltage
and current is being supplied to the magnet, mechani-
cal parts should be checked to assure that they are in
good operating condition and properly installed.
