5.5.1
Automatic
Automatic mode starts as soon as you connect the device to the battery.
The device monitors the battery voltage independently.
The EFOY Pro fuel cell switches on automatically if the battery voltage
drops below 12.3 V / 24.6 V (factory setting: Lead batteries). The battery is
then charged until the cut-off threshold of 14.2 V / 28.4 V is reached (fac-
tory setting: Lead batteries).
When the device is started, it goes through a start phase, which may last
up to 20 minutes. It only reaches its full rated output after this phase.
During normal operation, the EFOY Pro fuel cell briefly interrupts power
generation several times each hour. A charging current of 0.0 A is dis-
played when this occurs. This interruption lasts maximum 30 seconds.
INFO:
If the device fails to start, check that the cap is not still attached to the ex-
haust hose connector. Remove the cap.
INFO:
To ensure optimal battery maintenance, the charging current must not be
stopped abruptly when the cut-off threshold is reached. For this reason,
the EFOY Pro fuel cell continues charging the battery for up to three
hours at a reduced current after the configured cut-off threshold is
reached (factory default lead batteries: 14.2 V / 28.4 V). The length of the
recharging period depends on the battery voltage and power consump-
tion.
