7.2 VE.Bus LED indications
Inverters 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 two groups: OK codes and error codes.
7.2.1 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 will 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 will only be displayed if a device is not inverting!

The "inverter on" LED must flash.

A flashing "overload" LED indicates that the device can perform inverter
operation.

A flashing "temperature" LED indicates that the device is not blocking
charge operation. (This is just a formal indication which originates from the
relationship with the Phoenix Multi. This indication has no special meaning
on a Phoenix Inverter)
NOTE: The "low battery" LED can function together with the OK code that indicates
that the device does not block charge.
7.2.2 VE.Bus error codes
If a VE.Bus error occurs (example: a broken UTP cable) the system will switch off and
the 'inverter on' LED will flash.
If such an error occurs one should switch all units off, verify all cabling and switch the
units on again.
Additional information about the errror can be retrieved from the Inverter with the
VE.BUS System Configurator or the VE.BUS Quick Configure tool.
