Commands
The selection of a command (see page 30) results in the immediate execution of the command
or the opening of an intermediate confirmation window.
Proper execution is accompanied by a confirmation window that disappears from the display on
its own.
There are some commands that immediately activate test sequences without any confirmation
window:
 Self-test
 Ekip Signalling 2K module commands
IMPORTANT: the confirmation shown on the display refers to the launch of the
command and not to the verification of the operation requested, which is the
responsibility of the user, whatever the command: reset parameters, display,
opening/closing contacts
Exceptions

to certify that there is no conflict or incorrect condition.
 If the Trip unit detects an incorrect condition, the details are shown on the display and
the parameter change is canceled.
Even before executing a command, the Trip unit checks all its parameters to certify that there is
no conflict or incorrect condition.
 If the Trip unit detects an incorrect condition, the details are shown on the display and
the command's execution is interrupted.
