1.0 Safety notes

 Caution! Explosive gases are

generated during charging of

batteries!

 Only charge batteries in well

ventilated areas. Explosion hazard

on account of generation of

oxyhydrogen gas!

 Avoid all forms of fire, naked light

and sparking!

 Wear protective goggles!

 If acid splashes on to skin or

clothing, wash off immediately

with generous quantities of water!

 Caution!

If there is a pungent smell of gas,

acute explosion hazard is present!

 Do not switch the charger off!

 Do not remove the charging clips!

 Thoroughly ventilate the area

immediately!

After adequate ventilation, switch

the charger off!

 Check the battery!

 Protect the charger from damp and

wet!

 Install the charger such that the air

outlet is free!

 Ensure stable location of the

charger!

Electrical safety:

Mains and charging cable must be in perfect

condition. If these cables are damaged in

any way, contact the authorized workshop or

your expert dealer.

 Before start-up of the unit read the

operating instructions carefully.

Always operate the charger according to

these instructions.

2.0 Description of the unit

With the battery charger HS 12/24-30 (in the

following „HS“) all 12- and 24V wet batteries

(also lead calcium), maintenance-free gel

batteries, fleece batteries and

AGM-batteries can be charged.

The required voltage can be selected with the

„charging voltage switch“ (1).

The unit is switched on, the lower yellow

LED (0%) flashes:

Either there is no battery connected or there is

no contact with the battery.

With changeover switch (5) you choose the

battery type:

2.4 V/cell for wet batteries / AGM-batteries

2.35 V/cell for gel batteries

The microprocessor of the HS controls the

charging current according to the discharge

degree of the battery and automatically

provides optimum charging.

Working on the open

unit may only be done

by an authorized and

skilled expert!

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 (IN = 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: IN = 30 A

For 24 V: IN = 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).

- 4 -

 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.
