4.12 Memory backup

4.12.1 Memory backup
When changing the internal battery for the memory, all settings will be lost. The memory backup feature gives
the possibility to back up the controller settings, and after replacing the battery the settings can be restored.
DEIF recommends that a backup is made at least when the commissioning is tested and done. The following
settings will be stored in the backup:
Type
Identifiers
Counters
Views configuration
Inputs configuration
Outputs configuration
Translations
M-Logic configuration
AOP-1 configuration
AOP-2 configuration
Application configuration
Parameters
Modbus configuration
Permissions
Logs
If new firmware is flashed to the controller, the backup will be erased.
The controller will reboot after a backup has been restored.
The backup is found in parameter 9230 Memory backup with the jump menu. In this parameter you are able
to backup or restore.
Internal battery alarm
If the internal battery is dismounted during operation, a failure will appear on the display.

4.13 Load sharing

4.13.1 Load sharing
The analogue load sharing line enables the unit to share the active load equally in percentage of the nominal
power. The analogue load sharing is active when the genset is running in P load sharing mode and the gener-
ator breaker is closed.
A voltage signal equal to the load produced by the genset is sent to the load sharing line. When the generator
load is 0 %, 0 V DC is sent to the load sharing line. When the load is 100 %, the voltage will be 4 V DC.
