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)

prepared, the magnet is bolted in place with capscrews and lock-washers. (Figure 2)

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.

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.

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)

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 10

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.

Armature

Magnet

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 located, 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 4

Push the assembly against the retainer ring.

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 position 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 maintained throughout the life of the unit. (Figure 5)

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)

Conduit Box

Installation Instructions

Conduit box kit No. 5200-101-010 contains all components needed to assemble a conduit box for PB500 and PB650 brake.

Components

When pr

operly installed, this conduit box is designed to provide a proper means for field wiring terminations. It conforms to the requirements of Underwriters Laboratories.

Do not connect rigid conduit

ectly to the conduit box. A minimum of 12”

dir 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 conduit 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 grommets 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 4

Connect electric supply cable to the fitting installed on the conduit box. If an external power supply is furnishing 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

ews (11) and ring terminals (9-1). The

scr 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.

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 6 - AC Connection

When a CBC-100 power supply is used, refer to installation sheet P-266 provided with the CBC-100, following instructions car 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 provided in the mounting kit. Connections to the magnet or field terminals are as outlined in Step 5.

efully. To

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 and Maintenance

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 naturally 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 installation, the unit should be burnished by slipping the friction surfaces together at reduced voltage. It is recommended 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.

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 recommended. 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 r fast, repetitive cycle operation.

equires

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, lubrication, or maintenance should be required throughout the life of the unit.

Foreign Materials: If units are used on machinery wher

e 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 transmissions 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 surfaces 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.

Warner Electric • 800-825-9050 819-0485

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

que completely, the initial check should be the

tor input voltage to the magnet or field as follows:

90-Volt Series: Connect a DC voltmeter with a range of 0-100 or mor

e 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 mor

e. A normal reading is

approximately 22-26 volts.

If the above checks indicate that the proper voltage and current is being supplied to the magnet, mechanical parts should be checked to assure that they are in good operating condition and properly installed.

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 ar

e sufficient. Further checks may be made as follows: a low range ammeter, 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 resistance reading would indicate an open coil.
