carried out for 20 minutes (factory setting). During such a charge cycle the LED 14 is
lit and during equalizing it is blinking. Charge cycle with equalization can be started
independently from the actual program. For this purpose the slide switch must be slid
from “OFF” to the “ON” position. The LED 14 will light up. If the periodic equalization
is not required, slide switch must be slid back to the „OFF“ position after the
completion of the manual cycle.
The equalizing voltage can be changed. How to proceed is explained in chap. 5.3.
Batteries not designed for equalize should never been charged this way.
CAUTION: During the equalization process, the batteries produce a lot more
gas. DANGER OF AN EXPLOSION !! The battery room must be well ventilated.
Equalization mode should never be used when using Gel-Batteries.
4.6.4 Input current repartition (Power sharing)
To manage the power available on the AC INPUT (depends on the supply use) the
HP-COMPACT is equipped with a system usually called “Power sharing” or INPUT
power distribution. With this function it is possible to limit the AC INPUT current
assigned to the charger. The more current it uses on the OUTPUT the less it gives to
the charger. Priority to the OUTPUT. When the power sharing is used the LED 200%
(red) is lit to point out that the charge is limited.
Caution: if the power use on the OUTPUT is higher than the value of the INPUT
LIMIT (26) the HP-COMPACT cannot limit the current, then the generator means
to stop or the circuit breaker means to break before.
4.6.5 Set the INPUT LIMIT (26)
The current available for the HP-COMPACT
depends on the supply used from a motor
generator, the network of a camping or of a shore
connection. The value of the turning knobs INPUT
LIMIT (26) must be adjusted lower or equal to the
current available from the source.
For example if you have a generator of 2kW you
must adjust the turning knobs 26 to a max. 8.5A. To
calculate this, one divides the nominal power
(2000W) by the voltage (230V). If you have a circuit
breaker (i.e. 6A) before the HP-COMPACT, then
you set this value on the turning knobs (26) (i.e. 6A).
This adjustment can be done remotely with the optional RPS-01 (see section 3.6.7).
In that case the smallest values will be taken into account.
4.6.6 Charging current
The maximum charging current for the battery can be adjusted with the Turning Knob
22 (CHARGER). The charging current of the battery should be set to approximately
10 – 20% of the battery capacity (at C10). This means that the charging current for a
battery with 300Ah should be set between 30 – 60A.
The charging current is displayed on POWER MONITOR (25) of the front panel
or on the Remote Control.
4.6.7 Battery Condition
Built-in microprocessor with a specially developed algorithm calculates the actual
state of charge of the battery and displays it on LED 15 – 18. The LED 14 is lit when
the system is carrying out a charge cycle with equalization.
Notice: the exact measure of the battery state of charge with electrical parameters is
al-most impossible. The display of the state of charge is always more or less precise.
