18.1 List of Fault Displays
The meaning of fault messages displayed by the Sunny Island 3324/4248 are
explained in the following table:
Fault display Cause Fault correction
CBT-Open The battery temperature sensor is
missing or not correctly connected. Connect the battery temperature sensor
(see section 5.4.2 "Battery Temperature
Sensor" (Page 46)).
The battery temperature sensor cable is
defective. Change the battery temperature sensor.
Warning: Do not shorten the battery
temperature sensor cables!
CBT-Short Short-circuit in the battery temperature
sensor. Change the battery temperature sensor.
Warning: Do not shorten the battery
temperature sensor cables!
The battery temperature sensor cable is
defective. Change the battery temperature sensor.
Warning: Do not shorten the battery
temperature sensor cables!
ChargeLow This fault occurs when the battery state
remains in the critical area for an
extended period of time ("Critical"), i.e.
the batteries have not been charged in
time (see section 11.3 "Deep Discharge
Protection/Battery State" (Page 105)).
Possible causes: The Sunny Island 3324/4248 can be
started to charge the batteries after the
fault has been confirmed.
Requirements:
The system has enough energy available
for charging the batteries from a
generator or the public grid.
The generator does not start when
requested by the Sunny Island 3324/
4248. Check the generator fuses.
Check the fuel supply (diesel).
Energy consumption is higher than that
provided by the power generator (e.g.
PV generator). Switch off the energy consumers/loads.
CHS-Open Device fault Please contact the SMA hotline (see
section 20 "Contact" (Page 151)).
CHS-Short Device fault Please contact the SMA hotline (see
section 20 "Contact" (Page 151)).
CTR-Open Device fault Please contact the SMA hotline (see
section 20 "Contact" (Page 151)).
CTR-Short Device fault Please contact the SMA hotline (see
section 20 "Contact" (Page 151)).
FailSet Device fault Please contact the SMA hotline (see
section 20 "Contact" (Page 151)).
HotACout The Sunny Island 3324/4248 will not
start because voltage already exists on
the AC output terminals. Check for installation faults at the AC
connections (see section 5.3 "AC
Connection" (Page 40)).
Installation fault in the stand-alone grid.
Remove all voltages from the AC output of
the Sunny Island 3324/4248. Repeat the
start process.
