Input voltage protection
If a fault may occur on the input, the charger is protected by means of a fuse.
This fuse can be reached by removing the bottom plate of the charger. It is
located at the input side, where the power cord enters the charger. For
replacement, always use a fuse with the same value as the original one. See
specifications on page 54.
Input voltage monitoring
If the input voltage drops below 180VAC, the charger will protect itself and
pauses the charge process. The 'power' will light up red. The charge process
will be continued automatically if the input voltage has risen to 190VAC again.
Automatic voltage compensation
The charger automatically compensates for the voltage drop over the
connection cables. This compensation is optimized for the standard cable length
of 1 meters. To secure the correct working of the voltage compensation, it is
preferred not to change the length of the cables.
Charge time monitoring
All phases of the charge process are time monitored, but in particular the first
stage, the boost phase. If this phase takes longer than 14 hour, the charge
process will be stopped and the ' power' LED will light up red. Most important
requisite of this feature is that this way is prevented that the charger keeps on
charging a broken battery. But with this feature it also can become clear that
the charger doesn't fit the specific situation. For instance that the charge
current isn't in the correct proportion to the battery capacity (the battery can
become damaged when the charge process takes too long) or due to the
presence of users there is insufficient current left for charging the battery.
Battery voltage protection
After switching on, the charger first monitors the battery voltage. If the charger
doesn't detect a battery, the power led will light up red. If the charger measures
a battery voltage that is too low, so the battery is discharged too deeply, the
power led will light up red for 3 minutes as a warning. The charging process will
not start when the battery voltage is too high. Then the power led will also light
up red.
Temperature-compensated charging system
By connecting the optional temperature sensor T-Sense1, it is possible to adjust
charging process based on the battery temperature. Read more about this in
the relevant chapter.
Level of protection
The indication for
(International Protection) followed by two or three digits that stipulates the
conditions that it complies with.
The first digit refers to the class of protection for density, the second digit to
the fluid density and the last digit refers to the impact resistance. The LBC
500S can be assigned IP 205, which means:
2 = the charger is protected against solid particulate larger than 12mm.
0 = the charger is not protected against water/liquid etc.
5 = the charger can bear an impact force of 2.00 Joule (2Nm) max.
