Preform Pre-start Checks

To ensure that the drive is not unexpectedly started, turn OFF and lock out or tag
out the power source before proceeding. Failure to observe these precautions
could result in bodily injury.

Failure to perform any or all of these pre-start checks may cause damage to the
equipment and/or cause SERIOUS INJURY or DEATH to those in the work area.

Failure to perform any or all of these pre-start checks may also be a misuse
of the equipment. Any misuse of the equipment may void the warranty.

1. Make sure ALL shields are in place.

ALWAYS keep ALL guards and shields in place, until all the power is
disconnected and locked out.

2. Inspect the collector ring for any problems or potential problems.

5. Start-up

3. Be aware of any emergency shut down procedures. Two (2) people must always be in a position
where the operation of the equipment can be monitored.

4. Before starting the auger for the first time, make sure that all parts are assembled correctly
according to the instructions in this manual.

Make certain ONLY trained operators are in the work area before operating or
moving the machine. Two (2) people must always be in a position where the
operation of the equipment can be monitored.

PNEG-1722 Series II Sweep Protected Cord Slip Ring Sump 21

6. Maintenance

Phone: [phone]

3. Make sure ALL electrical wiring is not damaged and that it meets proper wiring codes.

4. Make sure ALL components are in good working condition before use.

5. Grease the center pivot tube at least two (2) times each season.

Slip Ring Maintenance

Lubrication

All bearings are lubricated for life at the factory. Additional lubrication should not be required.

Do not apply any lubricants or solvent cleaning agents to any part of the
slip ring.

Brush Holders

Make the first inspection shortly after installation and before operation. Make continuing inspections on
a regular basis after every 200-400 hours of operation under normal conditions.

Brush Holders

1. Inspect brush holders for proper alignment. Locate brush holders so that the entire brush contact
surface rides squarely on the ring with the brush moving freely in the brush holder. Position brush
holders so that the brush makes contact with the middle of the conductor and is not offset.

2. Check brush holder clamps for tightness. Set clamp bolts at 10 in-lbs. maximum.

3. Inspect brush terminations at the holder to assure that no external force is imp osed on the holder.
We recommend flexible or soft wire leads for these terminations. Use external clamps to support
the entire weight of the leads.

22 PNEG-1722 Series II Sweep Protected Cord Slip Ring Sump

6. Maintenance

Brushes

1. Inspect for wear. If the distance from the top of the insulator to the lower part of the brush spring is

0.093" or less, replace the brush.

Figure 6A

2. Inspect brush contact surface by removing the brush. Remove surface dirt, oxidation, pitting or
other contaminants (with a wire brush).

3. To remove and replace the brush:

a. Remove the clamp screw from the brush holder.
b. Remove the screw from the brush lead.
c. Remove the brush holder.
d. Replace the brush.
e. Re-assemble.

Brush Fit Inspection

1. Brushes must run at 90° ± 3° square on the rings. If brush is not square, adjust position of brush
holder on brush post.

2. Brushes need not run on the center of the rings, but there should be no forceful friction against
the insulators.

3. The brush spring cross-bar must be seated in the brush slot.

PNEG-1722 Series II Sweep Protected Cord Slip Ring Sump 23

6. Maintenance

Figure 6B

Brush Springs

1. Inspect and test brush springs to assure uniform brush pressure. If brush springs fall below
recommended pressure, replace entire brush holder.

Brush Spring Tension

Brush Amperage Spring Pressure

15 1.0 lb. min
35 1.5 lbs. min
75 3.0 lbs. min

Figure 6C

24 PNEG-1722 Series II Sweep Protected Cord Slip Ring Sump

6. Maintenance

Rings

1. Inspect the ring surface for dirt, oxidation or other contaminants. A properly operating ring will have
a film that appears burnished in color with a darker surrounding color where the brushes track.
If the ring requires cleaning, order slip ring polishing kit #41286.

Electrical Connections

1. Inspect all electrical connections for corrosion and tightness. Clean corroded parts with a wire
brush and/or muriatic acid. Loose and/or corroded terminations will cause a concentration of
excessive heat.

Brush Rigging

1. Brush posts are supported between two (2) outboard bearings. The brush posts extend to the
outboard bearings and are secured by a notch in the outboard.

2. Spacing between the outboard bearings is critical to assure the free rotation of the brush rigging.
The brush posts are cut to an exact length in order to provide the proper spacing. Locate the
outboard bearings against the insulator and have a 0.20" clearance without deformation of
the material.

Do not over-tighten the outboard brush post jam nuts. Make a final check to
assure there is no binding of the outboard brush rigging or binding of brushes
with insulator barriers.

Enclosure Inspection

1. Moisture is a major cause of slip ring deterioration. Water will corrode parts and breakdown
insulation. Dust and dirt present within the enclosure will effect the proper operation of the
assembly. Most dusts cause excessive brush and slip ring wear and conductive dust, if allowed
to accumulate, will form a path for short circuiting.

2. A properly designed NEMA 4 enclosure will be dust tight and watertight. However, NEMA 4
enclosures do not eliminate internal condensation. Condensation can be eliminated with the
addition of a breather, drain and a thermostatically controlled heater.

3. Periodically perform an inspection by removing the enclosure and checking for condensation, water
and dust collection. If contaminants are found, wipe the enclosure and the assembly with a lint free
cloth. If the problem persists, take steps to remedy the leakage or condensation problem.

Slip Ring Storage

1. When storing the slip ring, keep it at room temperature in a clean, dry, protective place. Place
self-contained or bagged absorbent material in the collector ring enclosure during extended periods
of storage. Remove absorbent material before putting collector ring into operation.

Serial Number

1. Make the following information available when ordering replacement parts or discussing the slip
ring with the factory by recording the information in the spaces provided here. This information is
located on the packing slip, factory invoice and serial number tag.

Catalog No. Slip Ring:_________________________
