TABLE OF CONTENTS
NOTES & TIPS FOR OPTIMUM
PERFORMANCE
• Confirm your power supply meets the
EEPM requirements.
• Stock is of ferrous metals, or any
grade of steel and cast iron.
• Stock is of sufficient thickness and
material type.
• Smooth clean contact between the
magnetic chuck and the workpiece.
• Your results will vary depending
upon the size, shape, thickness and
material type you are holding.
ELECTRICAL NOTES
• Electricity is NOT required to maintain
magnetic holding power.
• Electricity is used only to reverse the
polarity of the alnico magnets.
• When in a magnetized state, holding
power is secure until demagnetized.
• The chuck will NOT lose holding
power in the event of a power loss.
• To prevent injury never put any part of your body (i.e.
fingers, skin, etc) between a metal object and the chuck
surface. Do not wear rings, watches, necklaces, bracelets
etc., while operating the chuck.
• To prevent damage to the chuck and/or controller wait at
least two (2) minutes after magnetizing or demagnetizing
the a
• Always make sure the power receptacle on the chuck and
the plug on the chuck controller cable are free of moisture,
chips, and any contaminants before connecting the chuck
controller cable to the chuck. Failure to do so could result
in damage to the chuck and chuck controller.
• Always verify that the controller is properly connected to
the chuck before operating the controls.
• Always replace the cap on the chuck power receptacle
when disconnecting the power cable from the chuck.
• Always use workstops when operating the chuck at a
power level lower than 8 to ensure the workpiece does not
move during machining.
• High temperatures (176˚F or above) will cause permanent
decay / loss of magnetic power. Do not operate the chuck
under high temperature conditions.

FACTORS THAT AFFECT MAGNETIC HOLDING POWER
• Higher carbon content in the workpiece reduces the magnetic
attraction between the chuck and the workpiece.
• Thickness of workpiece
a) above 1-1/4” = 100%
b) 3/4” – 1-1/4” = 85%
c) 3/8” – 3/4” =50%
• Contact surface between workpiece and chuck. Chips, burrs, oil,
dirt, rough or uneven surfaces will reduce holding power.
• Contact area with the chuck. Holding power is approximately 1 ton
for every 4 poles.
• Temperatures above 176˚ will reduce holding power.

POWER SUPPLY CHECK PROCEDURE
The EEPM chuck and controller must have the correct
power supply to operate safely. Have a certified electrician
test and verify that your power supply meets the power
requirements listed below. Write the actual readings in the
spaces below, and fix any problems before attempting to
install and operate your EEPM chuck.
ELECTRICAL CONNECTIONS
The chuck controller requires 208-480V/30A single phase
power. For the single phase input, the cable has three leads.
1. Connect the wires as shown in the connection diagram (right).
2 cable leads are provided for phase/neutral, and one for ground.
2. For your convenience we have installed a NEMA L8-30P plug on the
chuck controller power cord. You will need to provide a NEMA L8-
30R receptacle. See drawing of the NEMA L8-30R.
We recommend having a certified electrician make all electrical connections and complete
the Power Supply Check (below) to ensure proper power supply and wiring connections.

CONTROLLER-TO-CHUCK CONNECTIONS
Place the chuck controller next to the CNC machine’s control panel
in a location away from chips, oil, coolant, and any moving parts of
the machine, but near enough to the machine bed and EEPM chuck
for convenient operation.
1. Connect the chuck controller power cable to the correct power source
(208-480V/30A single phase)
2. Connect the standard or touch screen remote cable to the controller.
3. Remove the cap from the EEPM chuck power receptacle and gently spray the
with dry shop air to knock out any unseen contaminants.
4. Connect the power supply cable from the controller to the power receptacle on
the chuck. Make sure it is properly secured.
INTERFACING WITH A CNC MACHINE CONTROL
The EEPM magnetic chuck controller can interface with most CNC
controls via the 9-pin connection on the back of the controller,
allowing the magnetic chuck to be operated from the CNC control
panel.
The magnetic status of the EEPM chuck (demagnetized or
magnetized) is indicated with a set of dry contacts connected to
pins 1, 2, & 3 of the CNC control connector. When the contacts close
between 3 & 1, the chuck status is “demagnetized.” When the same
contacts are open, the chuck status is “magnetized.” The contacts
between 2 & 1 operate in reverse of 3 & 1.
To magnetize the chuck, connect the negative of an external 5-26
VDC supply to Pin 9 and connect the positive 5-26 VDC to Pin 7 for 0.8
to 1.5 seconds. To demagnetize the chuck, connect the negative of an
external 5-26 VDC supply to Pin 9 and connect the positive 5-26 VDC
to Pin 5 for 0.8 to 1.5 seconds.
The pin assignments are as follows:
Pin 1 – Status Relay COM
Pin 2 – Status Relay N.O. Chuck is magnetized
Pin 3 – Status Relay N.C. Chuck is demagnetized
Pin 5 – Demagnetize command
Pin 7 – Magnetize Command
Pin 9 – Command Negative (0V)

STANDARD REMOTE OPERATION
DEMAGNETIZING THE CHUCK
1. Press the blue and the red buttons on the remote
simultaneously for 1 second and release.
2. Check that the red light above the red button on the
chuck controller is lit. This indicates the chuck is
demagnetized (OFF).
3. Verify that the chuck is demagnetized by touching
the surface of the chuck (touch test) with a ferrous
object (screwdriver). You should not feel any magnetic
attraction as the tip of the screwdriver comes in close
proximity to the chuck surface.
POWERING UP THE CONTROLLER
1. Turn the power switch on the chuck controller to “On”
2. Watch mag/demag light on controller is activated.
MAGNETIZING THE CHUCK
1. Press both the blue and green buttons on the remote
simultaneously for 1 second and release.
2. Check that the green light above the green button is lit.
This indicates the chuck is magnetized (ON).
3. Perform a Touch Test to verify magnetization. With a
small ferrous object (screwdriver) you should feel a
magnetic attraction.
ADJUSTING THE MAGNETIC HOLDING POWER
1. Adjust the power level as needed using the + or - keys.
Magnetize the chuck and verify that it is magnetized.
3. Perform the touch test to verify that the magnetic field
is no longer strong at the surface of the workpiece.
POWERING DOWN THE CONTROLLER AND CHUCK
1. Demagnetize the chuck and verify it is demagnetized.
2. Turn OFF the power switch on the chuck controller.
3. Disconnect the power cable from the chuck and gently
blow out the receptacle with dry shop air to remove
any contaminants. Replace the power receptacle cap
making sure it is properly secured.
The controller has 8 power levels. Level 1 is the weakest, and 8 is strongest. We recommend using level 8 for general operation. Using
the control panel or hand-held remote, you can adjust magnetic power levels to compensate for stock thickness or to provide better
chip evacuation.
You only need to adjust the holding power if a strong magnetic field extends beyond the surface of the workpiece. This is more likely
when workpieces are under ¾” thick. Perform a touch test to determine if it is necessary to reduce the magnetic power.

EEPM CHUCK OPERATIONS
CHUCK CONTROLLER MAINTENANCE
Regular routine maintenance includes keeping the exterior of
the controller, hand-held remote, and cables clean and dry.
Every time you use the chuck make the following inspections.
1. Carefully inspect all electric connections and condition
of the cables between the chuck and controller, and
the hand-held remote too. Make sure that no part of the
power supply circuit or connections has become loose or
show signs of overheating.
2. Make sure all cycle lamps are functioning well and the
keypad covers are all in good shape.
INDUCTION BLOCK MAINTENANCE
1. Holding power of the chuck is greatly influenced by
the contact area between the chuck (or induction
blocks) and the workpiece. Regularly check the
condition of all induction blocks and remove any
gouges, rust, or other signs of wear.
2. Machine the top surface of the inductions blocks as
needed to restore them to a smooth, even surface.
PART SETUP
1. Power Up and Demagnetize the EEPM chuck following the
procedures and CautionS and warningS.
2. If you are using fixed or spring-loaded induction blocks
install these on the chuck before loading your workpiece.
Then, machine flat the top surface of the fixed induction
blocks only.
3. Center your workpiece on the chuck. Position it so it covers
an even number of poles (4, 8, etc.) as evenly as possible.
4. Install workstops as needed. Small or thin workpieces
may require workstops to prevent the part from moving
during machining. For best results we recommend using
workstops whenever possible.
5. Adjust the power level as needed using the + or - keys. We
recommend using power level 8 for standard operation.
Magnetize the chuck and verify that it is magnetize.
6. Perform a touch test to verify that the magnetic field is no
longer strong at the surface of the workpiece. If a strong
magnetic field is present on the top of the workpiece adjust
the power level as necessary following the procedures
listed.
7. Verify that the workpiece is properly secured by gently
tapping it on the side with a soft hammer, or striking a
block of wood with a regular hammer while checking for
any movement.
8. After the machining is complete, Demagnetize the
EEPM chuck. You may now remove the workpiece.
SAFETY PRECAUTIONS
Follow these precautions while servicing the chuck and/or
controller:
• Only qualified personnel should carry out maintenance
operations
• Always make sure the receptacle on the chuck and plug
on the chuck controller cable are free of moisture, chips,
and any contaminants before connecting the chuck
controller cable to the chuck. Failure to do so could result
in damage to the chuck and chuck controller.
• Always replace the cap on the chuck power receptacle
when disconnecting the power cable from the chuck
• Disconnect the equipment from the power supply before
attempting any repairs or maintenance. Never touch
connections or components unless the power supply is
disconnected
• Do not wear rings, watches, necklaces, bracelets etc.
while performing maintenance operations
• Always use protective gloves, safety shoes, and any other
protective gear needed

EEPM CHUCK MAINTENANCE
STORING THE EQUIPMENT
If the need arises to store the equipment for a certain amount of time observe the following instructions.
1. Demagnetize the chuck.
2. Turn the power switch on the chuck controller to “OFF”
3. Disconnect the chuck controller from the power supply
4. Disconnect the controller from the chuck
5. Remove any moisture or debris from the chuck receptacle and replace the cap over the receptacle
6. Clean all components and coat the surface of the chuck in a protective, rust inhibitive solvent.
7. Cover the equipment with a waterproof sheet (plastic)
8. Keep equipment in a dry environment. To preserve all electric parts the room temperature must be between 45°F to 80°F
DISPOSING OF THE EQUIPMENT
If the need arises to dispose of the equipment, it is mandatory to observe a few fundamental rules for the
safeguarding of the environment.
1. Protective covering, flexible pipes, plastic or non-metal material should be dismantled and disposed of separately.
2. The electric components should be disassembled and if in good condition, re-used or recycled, or if that is not possible
properly disposed of according to local municipal regulations.
3. This equipment contains polluting oils that must be disposed of at authorized waste disposal sites.
There are no user-serviceable parts inside the chuck. Chuck maintenance is limited the surface finish of
the chuck face and verifying that the electrical connection is clean and uncontaminated by chips or liquid.
Proper maintenance increases the life expectancy of your chuck and controller and keeps them in safe
working condition.
WEEKLY MAINTENANCE
For proper operation the chuck surface must be clean and smooth. Regularly check the surface condition
of all magnetic poles for damage. Remove any gouges or roughness using 250 grit sandpaper with a
backing block. Finish the surface using 400 grit. Remove any rust or scale deposits with 400 grit sandpaper
and a backing block. Remove all dust or other contaminants before storing the chuck or returning it to
operation.
DAILY MAINTENANCE
Unscrew the cap and inspect the electrical socket connection on the front of the chuck. Make sure there
are no chips or other contaminants in the socket. Gently spray the socket and cap with dry shop air. Make
sure the socket and cap are clean and dry, and the cap functions properly and makes a tight seal. Any
contaminants or liquid in the socket may cause damage during magnetize / demagnetize operations.
