4.3.10.3 - Manual tests
This function allows the user to test the outputs individually, if
the machine is completely shut down (LOFF). To carry out a
manual test use the arrow keys to access the output to be tested
and press the Enter key (longer than 2 seconds) to activate the
modification mode. The password is automatically requested, if it
has not previously been verified. The Outputs/Test LED on the
user interface begins to flash. Enter the desired test value and
again press Enter to start the test. 'TESt' is displayed on the 4-
digit display alternately with the value tested. The Outputs/Test
LED stops flashing. Press the Enter key or an arrow key to stop
the test.
4.3.10.4 - Automatic tests
The automatic test function verifies the integrity of the analo-
gue entries and activates the outputs in sequence. For each test
't XX' is displayed on the user interface. 'xx' indicates the
number of the test in progress. When a test has been completed,
the following test is automatically activated.
A message may appear, asking the operator for a validation
with the Enter key, if the control cannot automatically verify a
sensor value or an output status. If the value read or the output
status is incorrect, the operator must press a different key (not
the Enter key) to cancel the automatic test procedure.
If a test fails, an error message and an error code are dis-
played. The automatic test procedure is interrupted.
When all tests have been completed, an end-of-test message
appears.
The table below describes the messages shown on the user
interface during the automatic test sequence.
