Victron energy Quattro 12/5000/200 User's Manual & Installation Manual page 27

The battery is overcharged.
The charging current drops to
0 as soon as the absorption
phase initiates.
7.2 Special LED indications
(for the normal LED indications, see section 3.4)
Bulk and absorption LEDs flash synchronously
(simultaneously).
Absorption and float LEDs flash synchronously
(simultaneously).
"Mains on" flashes and there is no output voltage.
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 two 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 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 in inverter or charging operation!
For a Multi/Quattro:
A flashing "bulk" LED indicates that the device can perform inverter operation.
•
A flashing "float" LED indicates that the device can perform charging operation.
•
For an inverter:
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 charging operation.
•
NOTE: In principle, all other LEDs must be off. If this is not the case, the code is not an OK code.
However, the following exceptions apply:
The special LED indications above can occur together with the OK codes.
•
The "low battery" LED can function together with the OK code that indicates that the device can charge.
•
The absorption voltage is set to an
incorrect level (too high).
The float voltage is set to an incorrect level
(too high).
Poor battery condition.
The battery temperature is too high (due to
poor ventilation, excessively high
environmental temperature, or excessively
high charging current).
The battery is over-heated (>50° C)
Defective battery temperature sensor
Voltage sense error. The voltage measured at the voltage sense connection
deviates too much (more than 7V) from the voltage on the positive and
negative connection of the device. There is probably a connection error.
The device will remain in normal operation.
NOTE: If the "inverter on" LED flashes in phase opposition, this is a VE.Bus
error code (see further on).
The battery temperature as measured has an extremely unlikely value. The
sensor is probably defective or has been incorrectly connected. The device
will remain in normal operation.
NOTE: If the "inverter on" LED flashes in phase opposition, this a VE.Bus
error code (see further on).
The device is in "charger only" operation and mains supply is present. The
device rejects the mains supply or is still synchronising.
Set the absorption voltage to the correct level.
Set the float voltage to the correct level.
Replace the battery.
Improve ventilation, install batteries in a cooler
environment, reduce the charging current, and
connect the temperature sensor.
Install the battery in a cooler environment
─
Reduce the charging current
─
Check whether one of the battery cells has an
─
internal short circuit
Disconnect the temperature sensor plug in the
Quattro. If charging functions correctly after
approximately 1 minute, the temperature sensor
should be replaced.
