Commands
You can set the behaviour of the circuit-breaker directly via
the Command submenu. The Trip command is currently
available.
Trip causes the circuit-breaker to trip irrespective of the
actual currents present and the set parameters. A current of
f40 % I
r
on at least one phase is necessary for the
execution of this command.
Remote operator
The assignment of the outputs Q4 and Q5 for the remote
operator of the NZM can be selected using this submenu.
If the remote operator is activated, both of the outputs are
mutually-exclusive, i.e. with Q4 “ON”, Q5 is “OFF” and vice-
versa. In the quiescent state Q4 is “ON” and Q5 is “OFF”.
Both outputs are “OFF” after activation of the remote
operator via the menu as well as after each time the DMI is
switched on. As a result, the remote operator will retain its
position until a control command is issued via the fieldbus.
Q Assignment
In the Q Assignment submenu you can assign specific
functions to the six digital outputs Q0 to Q5 of the DMI.
X In the Q Assignment menu use the cursor buttons Í or Ú
to select Q0 to Q5.
X Confirm your selection by pressing OK.
