Operating modes
The EFOY Pro fuel cell can be operated in one of the following modes:
Automatic
Manual On
Manual Off
External control on
Hybrid
5.4.1
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 24.4 V / 48.8 V (Lead batteries). The battery is then charged
until the cut-off threshold of 28.8 V / 57.6 V is reached.
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
every 20 minutes for maximal 20 seconds. A charging current of 0.0 A is
displayed when this occurs. The lost energy will be generated afterwards.
INFO:
If the device fails to start, check that the cap is not still attached to the
exhaust 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: 28.8 V / 57.6 V). The length of the
recharging period depends on the battery voltage and power
consumption.
