Safety Equipment; A) Polarity Reversal Protection; B) Error Notification; C) Anti-Spark Protection - VOLTCRAFT 1340001 Bedienungsanleitung

• If a battery to be charged is completely discharged, the charger first starts with a special restoration programme
(pulse charging). During this time, the value "25" flashes in the display (15).
• During the initial phase of the charging process, the development of the voltage is monitored. If the voltage of a
12 v battery is more than 10.5 v (24 v battery over 21 v), the charger switches to the charging programme
selected previously.
• The charger detects automatically if you connected a 12 v or 24 v battery. A battery with a voltage between 4.5 v
and 10.5 v is recognised as 12 v battery. A battery with a voltage between 16 v and 21 v is recognised as 24 v
battery.

9. SAfETy EqUIPMENT

a) Polarity reversal protection

The charger has an integral reverse polarity protection. If a battery is connected with incorrect polarity, the LED with
the exclamation mark (17) is lit. Check the polarity of the battery and the connection cable in this case.

b) Error notification

The charger continuously monitors the charging process. If a defective battery, battery voltage is too low or too
high, the charging duration too long (more than seven hours for the restoration programme or more than twenty-one
hours during charging) or a short-circuit is detected, the electronic system switches the charging process off. The
device is then in standby mode (only the POWER LED (1) is lit).
If a battery is definitely detected as defective, "FAL" is shown in the display (15). Dispose of these batteries as
described below in these operating instructions.

c) Anti-spark protection

The charger is still deactivated during connection to a battery. Therefore, unlike with conventional chargers, sparks
do not normally form due to a charge equalization when the charger is being connected to the battery. After the
connection, the charge state of the battery is checked first. Only after this test of the already connected battery does
the charging process start automatically.

d) Overheating protection

An overheating protection is built into the charger, which reduces the charging current automatically if the tempera-
ture in the charger is too high. When the internal temperature has dropped again, the charging process continues
completely normally.

e) housing protection type

The housing of the charger is designed protection type IP44 and thus serves to protect the charging electronics built
into the housing against dust and moisture. The plugs and connections do not meet this standard. The charger is
therefore approved for operation in dry, closed rooms only.
