MULTIcharger 4010 DC Operating Instructions
Temperature sensor
The use of the temperature sensor, which is stowed in the side of the
charger, is recommended for safety reasons. It should be attached to
the battery with the metal sensor element in direct contact (or as
nearly as possible) with one cell, as this gives the most accurate
temperature measurement. This provides an additional criterion for
charge termination.
Note:
If you do not wish to use the temperature sensor, and leave the sen-
sor inside the charger, it may cause the charge process to be termi-
nated prematurely due to the increase in temperature of the charger
itself. This is most likely to occur in high ambient temperatures, and
when the charger is used to fast-charge several battery packs in rapid
succession. To avoid this always remove the temperature sensor from
the case when charging.
Charge progress indication / charge termination
The progress of the charge is indicated by the red 40% and 80% LEDs.
The charge process is over when the green VOLL/READY LED flashes.
Pulsed trickle charge
At the end of the charge process the charger automatically switches
over to a pulsed trickle charge which continues indefinitely. To avoid
the trickle current overcharging the pack, disconnect the battery
from the charger as soon as possible after the end of the fast-charge
process. This is particularly important with NiMH batteries.
Safety timer
The MULTIcharger 4010 DC features a safety timer which starts when
the charge process is initiated, and breaks off the fast-charge process
automatically after six hours in the interests of safety. This terminates
the charge if for any reason the charger has not cut it off already by
detecting that the pack was full.

ISCHARGING
If you wish to discharge a NiCd pack or set of cells before charging it,
in order to avoid the memory effect (not necessary with NiMH bat-
teries), press the yellow button marked DISCHARGE before you con-
nect the pack. This is not necessary with NiMH batteries. The yellow
ENTLADEN/ DISCHARGE LED glows to indicate that discharging is in
progress. First a test phase lasting a minute is carried out, indicated
by the LEDs 40%, 80% and VOLL/READY flashing alternately. During
this period the charger establishes the final discharge voltage. As
soon as the discharge is complete, the battery is automatically
recharged (see Section 5). The charge current can be adjusted
during the discharge phase. During the discharge phase it is
possible to interrupt the discharge at any time by pressing the yellow
button marked DISCHARGE. The subsequent charge process then
starts immediately.
