TURNED ON.
C. DISPLAY LAMPS
TURN OFF RAPIDLY.
TROUBLESHOOTING
Possible cause
1) To operate the magnet, make sure the lift bail is in a relaxed postion. Then press the LIFT
button on the Front Panel or the I.R. remote. If no display indicators turn on, then the battery
voltage may be below the minimum acceptable operating level 11.6 volts. Charge the battery
until the voltage is at an acceptable level.
2) Check the battery terminals for corrosion and clean if necessary. Dirty terminals reduce the
voltage to the magnet.
3) Check the LED on the remote to assure it lights when the buttons are pressed. If not, change
he battery in the remote or try operating using the Front Panel Controls.
1) When the magnet is turned on, the alarm will normally sound for a few seconds while the mag-
net energy builds to the proper level for safe lifting. If the alarm continues sounding after several
seconds, then the battery level may have fallen below the danger level after the magnet was
urned on.
NEVER ATTEMPT TO LIFT A LOAD WHILE THE ALARM IS SOUNDING OR THE
RED DANGER INDICATOR IS ON.
The danger level is 11.6 volts and the magnet should not
be operated once the battery falls below this voltage. If the battery voltage is below 11.6 volts, it
must be recharged before further use.
2) The alarm will also sound if there is a break in the magnet coil, the magnet cord, or the con-
rol circuit, causing lack of current flow. Check to see if the magnet is securely connected to
he terminals on the control PCB. If the alarm persists, do not attempt to use the magnet. Call
1-800-W-MAGNET and ask for technical assistance.
3) Check the label located on the back of the control unit (inside the battery compartment) to be
certain it is the correct control for your magnet model. Controls are configured for use on specific
models.
1) After a complete battery charge, ALL the charge level lamps should light when the LIFT button
on the Front Panel or I.R. remote is pressed. The green lamps will turn off as the battery dis
charges, and will turn off faster with higher power consumption lift magnets. (BM

last green lamp(s) turn off minutes after the magnet has been turned on, this does not neces
sarily indicate a problem with the charger. Instead, it could be indicating the battery's inability to
accept its original full charge level.
2) As lead acid batteries age or become damaged internally, they become unable to accept the
full charge storage capacity, the lamps will begin to turn off sooner for the same previous "on
ime".
With increase aging and/or damage causing even less charge storage capacity, the lamps will
progressively turn off faster. Replacement batteries of lower reserve capacity than recommended
will result in the lamps turning off more rapidly and providing less usage time between charges.
Therefore, the user is cautioned to: OBSERVE THE BATTERY CHARGE LEVEL LAMPS FRE
QUENTLY DURING EACH LIFT. IF THE RED LAMP GOES ON AND/OR THE ALARM SOUNDS
DURING A LIFT, SET THE LOAD DOWN IMMEDIATELY.
3) Check the condition of the battery. Remove the battery from the magnet, and fully charge on
an external charger. After completing the charge, check the battery voltage using a voltmeter.
The battery voltage should read approximately 12.7 volts at a full charge. Let the battery sit for
15-20 minutes and re-check the voltage. If the voltage has dropped, replace the battery.
