OPERATION
1. Any battery must be recharged
(regardless of how long it’s been
used,) before the next use in order
to maintain the battery’s rated
capacity and cycle life. Typically,
the approximate recharge time is 8
hours after a 8 hour discharge
using the Ultralight lamp with either
the Luminator or Luminator Plus
Batteries. Longer recharge times
can be expected if the ML-2 lamp,
the remote power accessory, or
longer discharge times are used.
2. When power is supplied to the
charger, the power indication light
located on the front panel should
be on. Refer to the troubleshoot-
ing guide if light does not turn on.
3. To charge the cap lamp , the
headpiece should be fitted over
the projecting key on the front of
the charger and rotated clockwise
until it is in the full stop position.
Place the battery between the
guides located directly above the
station being used. To remove the
cap lamp from charger - reverse
the procedure.
After connection of the cap lamp, the
red LED will illuminate after a short
time, the circuitry will wait 5 seconds
then start the constant current charge
(stage 1) while monitoring the charger
voltage. When the charging voltage
reaches 5.3 VDC the charger switches
to a constant potential of 5.0 volts
(stages 2 &3) for a set period of time
(full charge is reached when the green
LED is on only), the charger then
switches to a “float” mode voltage of
4.6 volts (stage 4) until the battery is
removed. The battery state of charge
is indicated by the Charge Indicator
Guide
Note
The charging requirements for individ-
ual batteries are unaffected by the
state of charge of other batteries on
charge. If the battery is removed or
input power is interrupted, the charger
will reset to stage 1 when reconnect-
ed. The charger will quickly read the
level of charge in the battery then go
on to the appropriate stage where it
left off before the interruption. It is not
advisable to leave the battery partially
charged for any extended length of
time. Doing so will reduce the cycle
life and capacity of the battery.
MAINTENANCE
1. Each charger is supplied with an
extra fuse for 230 VAC operation.
Replace any broken fuses with the
following types which are readily
available through most electrical
supply sources:
• 115 VAC - fuse type -10A, T
10A
• 230 VAC - fuse type -5A,
TDC11 5A
The fuse holder is located on the
front, bottom right side of the
frame. To replace a blown fuse,
unscrew the fuse holder cover
counterclockwise. Remove the
blown fuse, place the new fuse in
the end of the cover and place
back into the holder.
2. Refer to troubleshooting guide if
the charger is not working proper-
ly, or to the cap lamp user instruc-
tions for battery operation.
3. Charging Contact Replacement
Remove top. Disconnect wires to
charging contacts.
Pull apart - disconnecting positive
charging key from retainer disk
