In cases where the generating set is equipped with a differential protection (with communication) or with a constant insulation checking device (with
communication), this menu is used to view the settings, fault current or insulation resistor.
Note: Press the M button for three seconds to bring up that same GENERAL screen, followed by the first welcome screen (see paragraph 1.6), where
the language, date and time can be changed at any time.
This can only be done when the generating set is running. All engine protection shutdowns stay active while these two welcome screens are accessed.
Generally, in all menus and submenus offered, if neither V or Esc is pressed the " overview " screen (see paragraph 1.7) appears after three minutes.

MENU
After validation using the V button, when the cursor flashes over the o sign next to Alarm/Flt, the ALARMS/FAULTS screen appears as follows.
This screen is used to view the list of the time and date stamped alarms and faults.
Any one screen can have up to two alarm and/or fault messages.
Each message on two lines comprises:
- One chronological number (from 1 to 50)
- Time (hour/minute/second) and date (day/month/year)
- Nature of the fault or alarm
- One asterisk (*) or dash (-) (see paragraph 11.1)

2 18h28m40s 12/01/00
alarm water temp.
Fifty alarm and fault messages can be recorded into the interface board CB or CB12 memory.
These messages cannot be erased. When the list is full (fifty messages), the fifty first message will make the first recorded message disappear
and so on.
On screen, alarms and faults are displayed in real time. If the cursor flashes next to number 1 (top of list), the appearance of an alarm or
fault is viewed straight away. If the cursor flashes next to a number other than 1, the new alarm or fault can be viewed after pressing , once
or several time depending on the cursor position.
Press
to view the list in ascending order (from number 1 to number x, x being the biggest number) or in other words, from the newest
to the oldest message.
Press
to view the list in descending order (from number x to number 1, x being the biggest number) or in other words, from the oldest
to the newest message.
The messages are always displayed two at a time (see the two screens below). The left-hand side screen shows messages number 5 and
6. The right-hand side screen shows messages number 6 and 7, after button
was pressed.

Just to the right of the chronological number of a fault (number x), appears an asterisk or a dash alternately with the cursor.
The asterisk (*) systematically appears as long as the fault is active (emergency stop not unlocked, breaker not reset, CAN bus disconnec-
ted, etc ...). This asterisk disappears as soon as the logical input associated with the fault is no longer active (logical status 0).
A dash (-) will then replace the asterisk to inform the operator that the fault has not been reset via the Reset button (see also paragraph
8.2).
A fault not reset which gets to the end of the list (x=50), is repositioned to the top of the list (x=1) as soon as another event appears (alarm
or fault). In this case, it will be time stamped again while repositioning itself to the top.

If an alarm always changes status (going from 0 to 1, then from 1 to 0, etc ...) with a frequency of less than two minutes, it is then only recor-
ded on the first occurrence and this for two minutes. After this period, the alarm is recorded again if it continues to change. However, keeps
the alarm displayed on screen even if the alarm keeps on appearing and disappearing. If another alarm or fault appears between two acti-
vations of the alarm previously mentioned, the recording will be made twice.

For all faults which are not linked to the status change of a logical input, it will not be possible to see the asterisk change into a dash.
Physically acknowledging the fault will not make the asterisk disappear and the dash appear. Press Reset to remove the asterisk and to ack-
nowledge the fault.
The faults concerned by this specific management are:
- Module 3CAN
- Module 4CAN
- Low alternator frequency
- High alternator frequency
- Low alternator voltage
- High alternator voltage
- Low battery voltage
