Still EXD-S 20, Original Instructions Manual

Page: 90 / 144

The charger adapts automatically to the bat-
tery discharge situation and therefore allows
any type of partial charging to be carried out
("opportunity charging").
The overcharging calculation takes into ac-
count partial recharging. The mixture is always
sufficient, without needless water consump-
tion, which prevents premature wear of the
batteries (often due to overlong charging peri-
ods) and reduces the need for maintenance.
Protection during charging
Mains micro-break protection
If the mains power is cut off, all the existing
charging parameters are stored in the memory
for 13 minutes. As soon as the mains power
returns, charging resumes from the point (I, U)
at which it was cut off, with the number of Ah
already injected stored in the memory.
If the cut-off period is longer than 13 minutes
(the truck could have been used), a complete
charging cycle is initialised.
Time protection
If the duration of phases I1 + P + U is more
than 16 hours, the charger automatically
stops. This can happen when a battery has a
short-circuited component. Simply reset the
mains to clear the fault.
Temperature safety
As the charger is cooled by ventilation, the air
inlets and outlets must never be blocked.
The fan runs when the mains power is con-
nected. It stops when charging is complete or
when the mains power is disconnected.
The charger supplies reduced power if the
ambient temperature exceeds the usage tem-
perature range in order to protect itself (the
charging period will be extended in this case).
The charger stops if the micro-controller de-
tects a temperature measurement fault.
Using the on-board charger
NOTE
The charger is compatible with wet lead and
gel batteries with a maximum capacity of
400 Ah.
CAUTION
Risk of damaging the battery
Do not disconnect the battery connector during
charging (green indicator light flashes).
The truck cannot be operated during charging.
WARNING
A battery produces explosive gases during charging.
–
Make sure that the area is well-ventilated.
–
Make sure that the battery hood remains open for
the entire time the battery is charging.
