3.7 DAS+ status
The DAS+ maintenance mode basically comprises five registers:
• DAS+ activation source (0x0FD2)
Indicates the source that was used to activate the DAS+ maintenance mode. It is
important to know the source, as the DAS+ maintenance mode can only be deactivated
again using the source that was used to activate it. For more information, see the section
"Activation source" below.
• DAS+ status (0x0FD4)
Indicates whether maintenance mode is currently activated or deactivated.
• Setting for current setting I
i DAS+ (0x1B5D)
The instantaneous short-circuit release is the most important protection parameter. For
more information, refer to Chapter "DAS+ maintenance mode" in the 3WA Equipment
Manual (Page 5).
• Activation/deactivation of the DAS+ function (0xF619)
This command can be used to activate the DAS+ maintenance mode. If the DAS+
maintenance mode has been activated using this command, it must also be deactivated
using the same command.
• Settings for ground-fault protection (0x2AFC to 0x2F26).
Depending on the implemented ground-fault protection, two protection parameters are
active: Current setting I
g DAS+ and tripping time tg DAS+.
INST DAS+ current setting Ii DAS+
Activation/deactivation of the DAS+ function
Settings for ground-fault protection
