CHARGING CYCLE
Setting: 14.4 V or 14.7 V
MULTI XS 7000 performs a 5-step fully automatic charge cycle,
IIUoIUp. Lamp B for 14.4 V or Lamp C for 14.7 V.
Start:
Starting phase for charging. The current is restricted to 3 A.
It ends when the voltage is above 10.5 V. There is a time-out after
6 hours and the charger switches to Error indication, (lamp 0). This
indicates a faulty battery or an undersized charger for the battery
pack. Lamp 1 indicates this phase.
Bulk:
Main part of the charge cycle when about 80% of the charge
is returned. The charge is carried out at maximum charge until full
voltage is achieved. Lamp 2 indicates this phase.
Absorption:
Final part of the charge. The voltage is kept constant
until the current has dropped to a very low level. The phase is also
ended if the total time for bulk and absorption exceeds 40 hours. Lamp
3 indicates this phase.
Pulse Maintenance charge:
The state of charge is between 95% and
100%. A pulse at 5 A is sent out if the voltage drops. This gives mini-
mum water loss and maximum life. The charger could be connected
for years without problems. The charger measures the voltage every
10 minutes to decide whether a new pulse should come. This means
that these pulses can’t come more often than every 10 minutes.
If the battery is charged and/or the battery's terminal voltage drops
below 12.7 V (Mode 14.4 V) or 12.9 V (Mode 14.7 V), the charger
starts a charge pulse of 5A until the terminal voltage has reached the
set level, 14.4 V or 14.7 V. The charge pulse is then interrupted and
the cycle is repeated as long as the charger is in pulse maintenance
phase. Pulse maintenance phase is indicated by lamp 4.
If the terminal voltage drops below 12.1 V, the charger automatically
reverts to the beginning of the charging curve.
Setting : Supply 13.6 V
MULTI XS 7000 has a Supply mode setting which has a constant volt-
age at 13.6 V and current up to 7 A. It could be used for maintenance
charge using the Float approach. This approach keeps the battery
at 100 % State of Charge, but the constant small overcharge also
increases water loss. Note that there is no need for a battery to be
connected at this mode. Note that the Spark Free function and the
indication of Reverse Polarity is suppressed in this mode. The protec-
tion is still working.
It is not advisable to charge a discharged battery in Supply mode as
this will not provide a complete charge.
In this mode, MULTI XS 7000 can also be used as a power-generation
unit for operating equipment that requires 13.6 V and a maximum of
7 A. If the selected current exceeds 7 A, the output voltage will drop at
an increasing rate. The charger has electronic overload protection in
this mode, which is activated if the charge is so great that the output
voltage from the charger falls below around 3.5 V and the current to
around 7 A. In the event of an overload, the charger transfers to error
mode (lamp 0).
Setting lamp D indication lamp 5.
Setting: Boost 16 V / 1.5 A / 4 h
MULTI XS 7000 has a Boost-setting which gives a constant current
at 1.5 A, maximised at 16 V for 4 hours. It will automatically go over
to 14.4 V pulse setting after a completed cycle. This mode is used for
batteries that have been deep discharged. Start by charging at either
the 14.4 V or 14.7 V setting until the battery is in Pulse maintenance
phase. Setting lamp E indication lamp 6.
BULK CHARGING TIME
TEMPERATURE PROTECTION
The charger is internally protected from being overheated. The power
will be reduced if the ambient temperature is increased.
MAINTENANCE
A MULTI XS 7000 doesn’t need any specifi c maintenance. Observe
that disassembly of the charger is not allowed and will void the
warranty.
A defective power cord has to be replaced. Keep your charger clean.
It could be wiped of with a soft tissue, after disconnecting the power
supply.
EQUIPMENT
MULTI XS 7000 is delivered with a set of battery leads with battery
pole clamps.
LIMITED WARRANTY
CTEK SWEDEN AB, Rostugnsv. 3, SE-776 70 VIKMANSHYTTAN,

or its representative with transportation cost prepaid. This warranty is
void if the unit is abused, handled carelessly or repaired by anyone
other than CTEK SWEDEN AB or its authorized representative. CTEK
SWEDEN AB makes no warranty other than this limited warranty and
expressly excludes any implied warranty including any warranty for
consequential damages. This is the only expressed limited warranty
and CTEK SWEDEN AB neither assumes nor authorizes anyone to

*) Back Current Drain is what drains the battery if the charger is con-
nected without the power cord connected.
**) Quality of the current and voltage is very important. High current
ripple heats up the battery and makes the positive electrode age pre-
maturely. High voltage ripple could harm other equipment connected
to the battery. MULTI XS 7000 produces a high quality current and
voltage with very low ripple.
