ENGLISH
These ampere ratings apply to the cold current drawn by a magnet when its
internal temperature is 68–77 °F (20–25 °C). Do not use the controller with a
magnet above or below the controller rated ampere range.
Type MF controllers include a slow-discharge fanning (dribble) control
feature.
1. Unpack the controller carefully. Remove the shipping tape from the
contactors.
2. Check the nameplate data for the correct equipment. Check that the
contactor operating coils are the correct voltages.
3. Check that all parts are undamaged and secure.
4. Bolt the controller securely into position. Provide adequate clearance in
front of the controller for opening the door, inspection, and maintenance.
Allow at least 1.5 in. ventilation clearance below the controller.
5. With all power disconnected, pivot the arc chutes upward and manually
operate the contactors. The power contact tips should meet squarely. If
they do not, refer to “Contact Tip Alignment” in the “Adjustment” section
of the contactor instruction bulletin.
6. Pivot the arc chutes back to their proper position.
7. Wire all external circuits to the disconnect switch in accordance with the
wiring diagram on the inside of the door.
NOTE: Drop contactors 1D and 2D and drop relay DR do not operate with the
magnet disconnected.
1. Place the pilot device in the “Drop” position.
2. Apply voltage to the controller. For the best performance, ensure that the
voltage is between 230–250 V.
HAZARD OF ELECTRIC SHOCK, BURN, OR EXPLOSION
• This equipment must be installed and serviced only by qualified
electrical personnel.
• Before working on or inside the equipment, turn off all power
supplying it.
• Always use a properly rated voltage sensing device to confirm the
power is off.
• Before turning on the power to this equipment, replace all devices,
doors, and covers.
Failure to follow these instructions will result in death or serious
injury.

INSTALLATION
ARCING HAZARD
• Electrical interruption produces an arc and hot particles.
• Do not stand directly in front of the controller when operating it with the
door open.
• Service personnel should wear personal protective equipment.
Failure to follow these instructions will result in serious burns.

3. Check the polarity with a voltmeter.
NOTE: The controller does not operate if the polarity is reversed.
4. With voltage applied to the controller, place the pilot device in “Lift“
position. Lift contactors 1L and 2L (also fanning contactor F in Type MF
controllers) should close freely.
5. On Type MF controllers only, hold the FAN push button down. Lift
contactors should open. Release the FAN push button. Lift contactors
should re-close.
6. De-energize the controller by placing the pilot device in the drop position.
The contactors in step 4 should re-open.
1. Disconnect power from the controller.
2. Make certain that all the arc chutes are pivoted to their fully down
position.
3. Connect the magnet.
4. Apply power to the controller.
5. Repeat steps 4–6 as listed in “Preliminary Startup”. Note that when drop
is initiated, drop contactors DR, 1D, and 2D should close for
approximately 1–3 seconds.
To adjust the controller for a clean drop without repicking, the controller has
a reverse current rheostat and monitor light. To obtain the best setting for a
given magnet, start with the rheostat knob set near MIN, then make lifts and
drops at successively higher settings until the light blinks at the end of the
drop cycle (see Monitor Light Operation nameplate), or until a clean drop is
obtained. Do not set the knob higher than necessary to get a clean drop on
all types of loads being handled. Reset the rheostat when the magnet is
changed.
Inspect contact tips on the lift and drop contactors on a regular basis for wear
and excessive pitting (see “Maintenance” in the contactor instruction bulletin
for instructions). Square D recommends that replacement contact tip kits be
kept on hand. Each kit contains two contact tips and mounting hardware.
Replace
both tips together.
During operation, periodically inspect for abnormal conditions. In particular,
inspect for the following conditions while the device drops a load:

• Excessive or unequal arcing when the two lift contactors open.
• Excessive or unequal arcing when the two drop contactors open.
Should either condition occur, shut down the system to prevent further
damage, and check the following items:
• Contact tips and pigtail connectors on all contactors
• Electrical continuity of all fuses, resistors, and the reverse current rheostat
• Electrical continuity of all electrical interlocks
• Shorts and grounds in the system, including the generator, cable, reel,
and magnet. Because ohmmeters may not detect grounds, use a 500 V or
1000 V meg-ohmmeter.
