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

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
