DMI
40
11/04 MN01219002Z-EN
The set values are retentively stored by the DMI and are
transferred during connection establishment every time the
DMI is restarted and also cyclically in normal data exchange.
Parameter deviation
As it is possible to set parameters both on the circuit-breaker
and on the DMI via a fieldbus, differences may occur
between the two sets of parameters.
Caution!
Selecting a new parameter without confirming the
previous parameter entry with
OK
will cause the previous
one to be lost.
Caution!
Selecting the Parameters submenu causes the DMI to
store all the values currently set on the circuit-breaker. If
the switch position of the circuit-breaker is changed whilst
the Parameters menu is open, these modifications are
not
recognised during the parameter assignment process.
Warning
Parameters that are changed via the DMI or via a fieldbus
are not retentively stored in the circuit-breaker. They are
lost if the power supply to the circuit-breaker is not
sufficient. A DMI is always required for retentive storage.

The

parameter LED flashes on the DMI if the parameter
sets are different (
