been activated (is operational).
The relay will drop out if zone selective interlocking has
been deactivated.
0x0024
ZSI input signal has been
received
(0 -> 1): safety - ZSI input is active
(1 -> 0): safety - ZSI input is not active
The relay will respond if the Zin input of zone selective
interlocking is active. The subordinate switch will
receive a blocking signal.
The relay will drop out once the device has been reset or
a reset command has been issued via the
communication interface. This function can be used to
check the ZSI functionality.

ZSI output signal has
been sent
(0 -> 1): safety - ZSI output is active
(1 -> 0): safety - ZSI ouput is not
active
The relay will respond if the Zout output of zone
selective interlocking is active. This breaker will send a
blocking signal.
The relay will drop out once the device has been reset or
a reset command has been issued via the
communication interface. This function can be used to
check the ZSI functionality.
