Once in the menu, it is then possible to test the voltage and
frequency protections by varying the thresholds and checking
that they disconnect correctly. To do so, access the start self-
test function
Start Autotest
with keys
and
and then
the results function
Results
. The process progress is displayed
on the lower part of the screen. The phase shown on the title bar
is the one being tested (the figure shows Phase 1 tests) whilst
the phase shown in the
Results
function line is the phase for
which the results of the last self-test have been saved (Phase 2
in the figure). The memory only has sufficient capacity for the
data for one complete self-test, therefore when each self-test is
executed, the data for the prior test are automatically deleted.

Status: Start
The different statuses of the
Autotest
algorithm are shown on the lower part of the screen as follows:
Start
An
Autotest
process is starting.
NotDone
There is no
Autotest
underway.
Vmax
The upper threshold limit of the voltage protection is being tested. The voltage protection value is
shown, which is gradually changed by the algorithm until disconnection is verified.
Reconnection
Each time a
Vmax, Vmin, Fmax
or
Fmin
status is completed, the connection status appears as an
indication that the following
Autotest
measurement is commencing.
Vmin
The lower threshold limit of the voltage protection is being tested.
Fmax
The upper threshold limit of the frequency protection is being tested.
Fmin
The lower threshold limit of the frequency protection is being tested.
Completed
When the
Autotest
has been completed.
The
Autotest
process can be interrupted at any time by selecting
the end self-test option
Stop Autotest
which appears in place
of the start self-test prompt
Start Autotest
whilst the test is in
progress.
Once a self-test has been completed, the results can then be
viewed by selecting
Results
. To do so, click on
OK
to access
the results and you can then scroll from one of the four screens
to another to view the results available. As an example, shown
below are the results for the
Vmax
and
Fmax
screens.
