Charging current indicator
The present charging current is being
indicated by 5 LED’s.
At the start of the charging process all
5 LED’s illuminate. With proceeding
charging the charging current will decrease
and the LED’s will extinguish from the top to
the bottom one.
When only the last LED (I
N
= 0%) is still
illuminated, the battery is charged.
When in addition the green LED (3) =
floating charge is on, the
HS
has switched
over to floating operation.
Maximum charging current:
For 12 V:
I
N
= 30 A
For 24 V:
I
N
= 15 A
For being charged the battery can
stay in the vehicle and does not
have to be disconnected from the
vehicle electrical system.
Absolute protection of the on-board
electronic system, as no current
and voltage peaks occur.
Backup mode
The
HS
replaces the vehicle battery in case
it has to be changed. The on-board voltage
will be maintained.
Floating mode
In the floating mode the
HS
ensures
optimum charging and floating charging of
the battery.
Wrong polarity protection
The
HS
detects wrong polarity connection
and will not commence the charging
process.
Release of clips
The
HS
surely detects, when clips become
detached from the battery during the
charging process.
- 3 -
Exhausted batteries
The
HS
also detects exhausted batteries
and will commence the charging process
carefully.
The
HS
will adjust the charging current
automatically.
3.0 Start-up
Observe the precautions in the
safety notes!
Observe the handling instructions
of the battery manufacturer!
Determine the battery type.
Set the battery type with
changeover switch (5):
2.35 V/cell for gel batteries
2.4 V/cell for standard batteries /
AGM-batteries
3.1 Charging
Attention: Check the correct position of
the switch S1 12V-0-24V when setting
the charge voltage.
Connect charging clips to battery
terminals with correct polarity
. Red
clip (+) to the positive terminal,
black clip (-) to the negative
terminal!
Set charging voltage with switch (1).
Charging indicators (2) illuminate.
When only the last LED (0%) is still
illuminated, the battery is charged.
Switch off the
HS
with switch (1).
Detach the clips from battery
terminals.
Charging exhausted batteries
The
HS
detects exhausted batteries.
The
HS
will commence the charging
process carefully with low charging
current and will subsequently adjust
the charging current to the battery
condition.
Battery voltage has to be at least 0,6 V.
3.2 Backup
mode
Set battery type with changeover
switch (5).
Set backup mode with changeover
switch (6).
Connect charging clips to battery
terminals with correct polarity.
Red clip (+) to the positive
terminal, black clip (-) to the
negative terminal!
Caution!
During battery change the
charging clips must not come
loose from the battery terminals.
Select required voltage with
switch (1). The yellow LED (7) will
illuminate.
During backup mode the current is
limited to 5 A.
A minimum load current of 0.6 A
must flow, e. g. the parking light of
the vehicle must be switched on.
Otherwise backup charging is not
possible.
With changeover switch (6) set back
the
HS
to „normal operation“.
3.3 Floating mode/trickle charge
Connect charging clips to battery
terminals with correct polarity.
Red clip (+) to the positive
terminal, black clip (-) to the
negative terminal!
Select required voltage with
switch (1).

Charging indicators (2) illuminate.
When only the last LED (0%) is still
illuminated, the battery is charged.
If in addition the green LED (3) = floating
charge illuminates, the
HS
has switched
over to floating mode.
If the battery is being discharged by a
consumer during floating operation, the
HS
automatically provides suitable
charging.
Floating mode can be carried out during
an unlimited period of time.
Observe the maintenance instructions
of the battery manufacturer.
Fault indicator (8) flashes:
- If temperature in the charger is too high
Is the air outlet at the rear panel of the
charger free?
Are the air intakes at the bottom of the
charger free?
After cooling down the
HS
automatically
continues the charging process.
- If charging clips have been connected
with wrong polarity
Connect the clips with correct polarity.
After elimination of the fault the fault
indicator (8) extinguishes.
- When battery voltage is too high
Determine voltage of the battery and set
accordingly with switch (1).
After correction of the voltage setting the
fault indicator (8) extinguishes.
- If battery is not correct or faulty
Check:
- the battery for defective cells
- the charging voltage which
has been chosen.
Connect new battery, switch
off the
HS
and subsequently
detach the charging clips.
