Changing a numerical parameter
A numerical parameter can be changed (only if R/W type),
as follows:
1.
Press the E key when the parameter you want to
change is displayed.
2.
The cursor is activated, with inverted colours, on the
digit of the parameter value corresponding to the unit.
Use the ▼ and ▲ keys to increase or decrease the
3.
digit under the cursor. When a value affecting the left
digit is reached, it is changed even if the cursor posi-
tion does not change. For example, increasing the digit
9 by 1 automatically increases the digit to its left by 1
and 9 becomes 0 without moving the cursor.
By using the ◄ and ► keys, the cursor can be moved
across all digits to set a value more quickly, including
non-significant zeros, which are not normally displayed
when confirming the data.
4.
To save the parameter value after editing, press the
Ekey again. To exit the edit mode without saving the
value, press the ESC key.

Changing a status parameter
To change a status parameter (COMMANDS menu):
1.
Press the E key when the parameter you want to
change is displayed.
2.
The current status description is displayed with invert-
ed colours.
Press the ▼ and ▲ keys to select a status from those
3.
available.
4.
To save the parameter value after editing, press the
Ekey again. To exit edit mode without saving the value,
press the ESC key.

ALARM screen
In the presence of an alarm, the red ALM LED is activated
and the ALARM screen is automatically displayed, show-
ing the details of the first alarm detected by the parameter
scan; the parameters show the status starting from the
least significant bit.
The ▼ and ▲ keys can be used to scroll through the details
of any other alarms that may be present.
When there are no more active alarms, because they have
been reset via the ACK key or reset automatically, the
ALM LED goes off and the HOME screen is automatically
displayed.
If you exit the ALARM screen, for example, by pressing the
HOME or MENU button, and there are still active alarms
(ALM LED lit), you must press the ALARM button to return
to the alarm screen.
If there are no alarms, the ALARM button does not cause
any change to the current display.

Alarm reset
There are two types of alarms:
•
Alarms with memory.
•
Alarms without memory.
To reset an alarm with memory, go to the ALARM screen,
which shows the details of the alarm in question and press
the ACK button. What happens next depends on the cause
of the alarm:
•
if the cause is no longer valid, the corresponding item
is deleted from the alarm list;
•
if the cause is still valid, the corresponding entry re-
mains in the alarm list.
Alarms with no memory are automatically reset when the
cause of the alarm ceases to exist. The ALM LED and
ALARM screen are updated accordingly.
