7.2 Special LED indications
(for the normal LED indications, see section 3.4)
Bulk and absorption LEDs f lash sy nchronously
(simultaneously ).
Absorption and f loat LEDs f lash sy nchronously
(simultaneously ).
"Mains on" f lashes and there is no output v oltage.
7.3 VE.Bus LED indications
Equipment included in a VE.Bus system (a parallel or 3-phase arrangement) can provide so-called VE.Bus LED indications.
These LED indications can be subdivided into tw o groups: OK codes and error codes.
7.3.1 VE.Bus OK codes
If the internal status of a device is in order but the device cannot yet be started because one or more other devices in the
system indicate an error status, the devices that are in order w ill indicate an OK code. This facilitates error tracing in a VE.Bus
system, since devices not requiring attention are easily identified as such.
Important: OK codes w ill only be displayed if a device is not in inverter or charging operation!
- A flashing "bulk" LED indicates that the device can perform inverter operation.
- A flashing "float" LED indicates that the device can perform charging operation.
NOTE: In principle, all other LEDs must be off. If this is not the case, the code is not an OK code.
How ever, the following exceptions apply:
- The special LED indications above can occur together w ith the OK codes.
- The "low battery" LED can function together w ith the OK code that indicates that the device can charge.
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 follow ed:
1. The device should be in error (no AC output).
2. Is the "inverter on" LED flashing? If not, then there is no VE.Bus error code.
3. 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.
4. Check the "bulk" LED, and determine w hich of the three tables below should be used.
5. Select the correct column and row (depending on the "absorption" and "float" LEDs), and determine the error code.
6. Determine the meaning of the code in the tables below .
Voltage sense error. The v oltage measured at the v oltage sense connection dev iates
too much (more than 7V) f rom the v oltage on the positiv e and negativ e connection of
the dev ice. There is probably a connection error.
The dev ice will remain in normal operation.
NOTE: If the "inv erter on" LED f lashes in phase opposition, this is a VE.Bus error
code (see f urther on).
The battery temperature as measured has an extremely unlikely v alue. The sensor is
probably def ectiv e or has been incorrectly connected. The dev ice will remain in
normal operation.
NOTE: If the "inv erter on" LED f lashes in phase opposition, this a VE.Bus error code
(see f urther on).
The dev ice is in "charger only " operation and mains supply is present. The dev ice
rejects the mains supply or is still sy nchronising.
