Possible causes
• The maximum current that should be drawn by a D10 controller is 300mA (momentarily); 200mA (continuous)
• This error indication is displayed in the event of excess current being drawn
• Too many auxiliary components connected to 12V auxiliary output
• One specific auxiliary device that is faulty, typically having a short circuit
•
Charging voltage significantly higher than 28V DC due to faulty charger or
controller
Solutions
• Ensure that the battery charging voltage is no higher than 28V DC.
• Disconnect and reconnect auxiliary component one by one in order to isolate the problem
