Channel 8
Byte 1
Switching status
"1" = The corresponding output channel is
activated.
"0" = The corresponding output channel is
deactivated.
Error status
"1" = The corresponding output channel is still
activated, but with over-current
(output current < nominal current, longer than
1 s).
"0" = The corresponding output channel has
been deactivated due to over-current.

*) (value transmitted)/16 A
Depending on the valence of bit 12 (byte 2), either the set nominal currents or the
momentary output currents are transferred in addition to the momentary input
voltage (see Table 20).
Electronic circuit breakers without active current limitation supply only the
momentary input voltage and the set nominal currents. Output currents are not
transferred.
