4.4.- OPERATING ERROR DETECTION
The
eHome
is capable to detect the following operating errors:
Ventilation required error.
Pilot error.
Proximity error.
Negative PWM error
Maximum output current DIP switch error.
Temperature error.
Whatever the error case is, the unit will stop charging and technical assistance will be required,
except from the temperature error. In this last case, the unit starts charging when the operating
temperature is reached again.
In the
Table 13
it will be explained how the
eHome
shows the above mentioned errors and the
actions taken by the device.

LEDs bar
Ventilation required error (D status)
(1)
In some old EVs, this state means that there are some gases com-
ing out from the batteries. So, an external ventilation in the car park
might be required.
Red, 1 blink
sequence
Pilot error ( E status)
(1)
When the device is connected to the EV, a Pilot short-circuit to eath
may occur.
Red, 2 blink
sequence
Proximity error
When the device is connected to the EV, a Proximity short-circuit to
earth may occur.
Red, 3 blink
sequence
Negative PWM voltage error
When the device is connected to the EV, the PWM signal, used to
communicate the device with the EV, can be negative.
Red, 4 blink
sequence
Maximum output current DIP switch error
If this on board current limit selection is not setup according to the
hardware features, the device detects it and shows this error.
Red, 5 blink
sequence
