If you have this error:
• Confirm the voltage of your CH3 Start Battery is above the corresponding Start-Up voltage above
•
Check you
have not left the “Priority” (Override) feature activated (Manual or Auto), when having
no engine and so its alternator not running.
•
Check the battery cable from the Start Battery is properly sized, to avoid excessive voltage drop.
• Make sure there is not any loose terminal or blown fuse.
• Check if there are DC loads drawing current from the CH3 Start battery, resulting in a net
discharging current.
E03 CH2 High Input Voltage Shutdown
This means the input from the CH2 Solar input has gone above 50V. This error will clear once the
input drops below 48.0V.
If you have this error:
•
Check the specification of your panels
– the Volts Open Circuit (VOC) should not exceed 50Voc.
•
If having panels in series for 24V nominal, make sure its voltage in open circuit (Voc) does not
exceed the 50V when having maximum sunlight condition. Otherwise, consider connecting the
solar panels in parallel (i.e. + to + and
– to -) for a 12V nominal panel array.
E04 CH2 Low Input Voltage Shutdown
The unit has detected the input from the Solar Array cannot sustain voltage above 14.5V.
If you have this error: This is not necessarily a malfunction.
• Check that you are not in a low light/non- direct sunlight situation i.e. early morning /late
afternoon, or even at night.
•
This may also happen if your solar panels are inside of a shed with a skylight or outside under
Flood Lights.
If you find this is happening with your unit when stored, we recommend fitting a DC breaker to the
output of the Charger and turning it off when the unit is not in use.
E05 CH1 High Input Voltage Shutdown
This means the unit has detected that the CH1 Main/House battery has gone above 16.0V/32V on
DMT1230-DMT1250 / DMT2430 respectively. This error will clear once the input has dropped
below 15.5V/31V respectively.
This may be due to charging from another charging source (i.e. Another solar controller or AC
battery charger) with either an excessively higher voltage regulation setting or a malfunction.
E06 Over Temperature Shutdown
When the charger
’s internal temperature rises above 65°C, the charger will shutdown. It will
recover automatically when the environmental temperature drops below 40°C.
• Check to make sure the fan is working.
• Make sure the unit has good ventilation.
E07 BTS Over Temperature Shutdown
This means the Battery Temp Sensor has detected that the batteries are too hot > 60°C and have
shut down to not over charge the batteries. The unit will return back to normal charging once the
battery temperature sensor is < 56°C.
If this occurs, check the temperature of the batteries.
•
If the Batteries are Hot
– you may have a dropped cell or faulty battery. Stop all charging and see
your local battery shop to get your batteries tested.
• Check the batteries and the charging current. The charging current may be set too high.
• If the Batteries/Terminals are still cool or only warm, you may have a bad temp sensor. Unplug
the temp sensor and contact KISAE.
A01 Over Temperature Warning
When the charger’s internal temperature is > 60°C, the unit will show ‘
A01
’. If the ventilation of the
unit is not improved, it will leads to
‘
E06
’-
Unit Over Temperature Shutdown .
The
‘
A01
’ warning code will disappear when the internal temperature drops to < 58°C.
•
Check if there is an object has blocked the air ventilation of the unit.
• Check if the fan is working.
• Make sure the unit has good ventilation.
A02 BTS High Temperature Warning
When the battery temperature sensor is > 58°C, the display will show
‘
A02
’. If the ventilation of the
battery environment is not improved and the temperature continuously rises, it will lead to
‘
E07
’-
BTS Over Temperature Shutdown.
The
‘
A02
’ warning code will disappear when the measured temperature drops to < 56°C.
• Check the batteries and the charging current. The charging current may be set too high.
•
Make sure the batteries have good ventilation.
