Commissioning the EFOY fuel cell
Page 60
To use the EFOY fuel cell, transportation protection must be deactivated using the EFOY app
or the operating panel.
4.2 Operation
The EFOY fuel cell indicates its status by way of the status LED on the device (see
S
ECTION
2.2, I
TEM
11
). A detailed overview of the LED color codes can be found in
S
ECTION
8
.
The EFOY fuel cell can be operated in two different operating modes:
• Automatic (see
S
ECTION
4.2.1
).
• Sleep (see
S
ECTION
4.2.2
).
For optimum operation of the EFOY fuel cell, we recommend always using the
Automatic operating mode.
The following functions can be carried out in both operating modes:
• Begin charging (see S
ECTION
4.2.3 ).
• Restart (see
S
ECTION
4.2.4
).
• Reset to the factory defaults (see
S
ECTION
4.2.6
).
For information on changing the operating mode using the button (see
S
ECTION
2.2, N

), refer to the overview in
S
ECTION

.
4.2.1 Automatic operating mode
Following the initial configuration and deactivation of transportation protection, the device is
in Automatic mode. The LED flashes green.
The EFOY fuel cell monitors the battery voltage by itself.
If the battery voltage drops below the switch-on voltage or switch-on threshold (see
S
ECTION
2.3
), the EFOY fuel cell switches on automatically.
The battery is charged until the switch-off voltage or switch-off threshold is reached (see
S
ECTION
2.3) . The EFOY fuel cell then switches off. The switch-off duration depends on the
switch-off current and absorption time (see S
ECTION
9 ).
In normal operation, the EFOY fuel cell interrupts current generation for
approx. 30 seconds several times per hour. A charging current of 0.0 A is
displayed here.
For optimum care of the battery, the EFOY fuel cell does not cut off the
charging current abruptly when it switches off. The EFOY fuel cell continues
charging up to the maximum absorption time (see
S
ECTION
2.3
) at a reduced
current. The duration of recharging depends on the battery voltage and
