Appendix C – Error codes
This table lists the error code shown on the Skylla-i Control panel.
Error nr. Description Action
E 2 Battery voltage too high This error will reset after the battery voltage has
dropped.
This error can be tripped if the battery is charged
by several independent chargers that have other
battery voltages programmed.
E 3
E 4
Remote
connected to BAT+
Remote
connected to BAT-
Check if the Temperature sensor connector is
properly connected to a remote temperature
sensor.
E 5 Remote temperature
sensor broken during
operation.
Switch off the charger and check the sensor
cabling, if the cabling is ok replace the sensor.
Warning:
After a power-up with a suspected faulty sensor
(open connection) the error will be gone. The
charger will not see a remote temperature sensor
because the connection is open, and will assume
that no sensor is connected and will charge the
battery without temperature compensation!
After replacing a suspected temperature sensor,
DO NOT just apply a new power-up, but power-
up and directly check if the Temperature sensor
OK LED is lit!
E 6
E 7
is low
Vsense- is high
Check the wiring between battery and Voltage
sensor connector. Check for polarity.
E 8 Voltage sense connection
to battery lost during
charging.
Check the wiring between battery and Voltage
sensor connector.
Check the FUSE in the lead near the
battery.
Attention:
After a power-up with a suspected broken
voltage sense-lead (open connection) the error
will be gone. The charger will not see a remote
voltage sensor because the connection is open,
and will assume that no voltage sense leads are
connected to the battery, and will charge the
battery without voltage compensation.
After replacing a suspected voltage sense lead,
DO NOT just apply a new power-up, but power-
up and directly check if the Voltage sensor OK
LED is lit!
E 9 Too large voltage drop
over battery cables during
charging.
Check if the charge-cable wire size is large
enough to handle the charging current.
This error can also be generated by corroded
connections of the battery poles.
Check poles. Tighten if necessary. Check wire
size.
