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 56.
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.
Current limitation
The charger incorporates a current limitation feature.
Charge time monitoring
All phases of the charge process are time monitored, but in particular the first
stage, the bulk phase. If this phase lasts longer than 14 hours with a lead-acid
battery, the charge will stop and the 'power' indicator will light up red. With a
LiFePO4 setting, this time limit is 24 hours. 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
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.
Temperature sensor protection
If the charger is set for the T-Sense1, but during use the charger fails to detect
the sensor, then the charger will stop charging and the red ‘power’ LED will
illuminate.
If the temperature sensor has not been activated, but while in use the charger
detects the temperature sensor, then the charging process will stop and the
