7.3.2 VE.Bus error codes
A VE.Bus system can display various error codes. These codes are displayed with the
"inverter on", "bulk", "absorption" and "float" LEDs.
To interpret a VE.Bus error code correctly, the following procedure should be
followed:
1. Is the "inverter on" LED flashing? If not, then there is no VE.Bus error code.
2. If one or more of the LEDs "bulk", "absorption" or "float" flashes, then this flash
must be in phase opposition to the "inverter on" LED, i.e. the flashing LEDs are off if
the "inverter on" LED is on, and vice versa. If this is not the case, then there is no
VE.Bus error code.
3. Check the "bulk" LED, and determine which of the three tables below should be
used.
4. Select the correct column and row (depending on the "absorption" and "float"
LEDs), and determine the error code.
5. Determine the meaning of the code in the tables below.
