Parker PL-8 Manuale utente
Parker’s portable magnetizing
coils are designed for
magnetic particle inspection of
ferrous metal parts. The coils
allow for the use of either dry
powder or wet uorescent
inspection media and may be
used for demagnetizing
as well.
The coils are molded in a
tough, black polyurethane and
come equipped with a 10’
(3.048 m) power cord including
a foot switch or optional hand
switch. The sealed electrical
connection box has a 2”
(50.8 mm) X 5” (127.00 mm)
at base allowing the coil to
stand in a vertical position.
The PL-8, PL-10, PL-8PDC, and PL-10PDC operate from a standard 115VAC, 60
Hz single phase grounded power source.
The PL-8S and PL-10S operate from 230VAC 50-60 Hz single phase grounded
power source. The PL-8S and PL-10S are sold without power cord plugs. Only
locally approved plugs should be used and installed by certied personnel.
Using an approved GFCI is recommended.

General safety rules
Always wear eye protection.
Please read all instructions. Failure to follow all instructions listed below may result in serious injury. If the equipment is used in a
manner other than is specified in these operating instructions, the protection provided by the equipment may be impaired.
Operating & Environmental conditions
Operating temperature: 32 F (0 C) degrees to 104 F (40 C) degrees. Relative Humidity 10% to 95% non-condensing.
Always operate from a grounded power source. Do not operate from a DC output.
General Cleaning
The outside surface of the instrument can be periodically wiped with a clean cloth. Avoid using cleaners such as lacquer thinner,
or mineral spirits that could damage the outside polyurethane housing.
Do not abuse the power cords. Never carry the instrument by the cord or attempt to unplug the instrument using the cord.
Always operate the instrument with the standard installed cable. Changing or using a damaged cord can increase the risk of
electrical shock. The cord should be checked periodically for any damage.
Do not position the instrument such that it would be difficult to operate the disconnect device (plug) on the end of the power cord.
The outside polyurethane housing should remain intact and solid. Any damage or chipping exposing internal wires is a hazard.
Instruments should not be used in this condition. The outside housing should be periodically checked for damage.
Never attempt field service
All PL series coils should be returned to the factory for repairs.
The coils are designed for a 50% duty cycle. All coils are equipped with an internal thermal switch that will shut down the device
if overheated. The instrument will automatically reset itself when the temperature drops. Continuous operation may cause
overheating and damage the coil.
OPERATION
Plug the power cord of the coil into the appropriate outlet. Depress the switch. A magnetic pull will be felt by insertion of a ferrous
metal object into the center of the coil. Inspection is accomplished by placing the part longitudinally parallel to the axis of the coil,
within the coil nearer to the outer circumference. (Fig. 1) Activate the switch and apply the inspection medium while the coil is
energized. This is referred to as the continuous method and will reveal defects at right angles to the coil or object axis.
When using the wet method, allow the coil to remain energized for approximately two seconds after applying the wet medium.
Remove the part for inspection.
To demagnetize a part after inspection, simply place the part within the coil near the outer circumference. While the coil is
energized, remove or pull the part approximately two feet (.609 m) away from the coil before turning the coil off. Larger parts
may be demagnetized by placing the coil directly over the part and withdrawing the coil in the same manner.
CAUTION
For the correct and safe use of this equipment, proper training of operating personnel to required inspection techniques,
specifications and safety requirements is necessary, and is the obligation of the user.
