The pages are scrolled using the "PAGE" key. Each time the key is pressed, the screen
moves up to the next page. After page 4, page 1 appears again.
For the display of current alarms and warnings, an alarm screen has been included. This
is called up using the "ALARMS" key. If there is no alarm, the message "no message"
appears on the screen.
A1 > no message
If an alarm is activated, the device switches automatically to the alarm screen. Each new
entry is made in the top line. Any messages that might already be present shift one line
downwards. In a column to the right of this, the code and current time are added. Al-
though a warning (message without alarm) is entered in the alarm screen, there is no au-
tomatic switch to that screen, e.g. in the case of a programmed ship alarm or ship-spe-
cific warning, see page 34.
The following codes are distinguished:
Warnings:
Warnings (preliminary alarms): WA
Main alarms:
Sensor error alarms:
Example:
Message text
A1 Coolant temperature
Charge-air temperature
Coolant level
Oil pressure, engine
Bilge pump ON
If there are more than 5 alarms (e.g. during commissioning in the shipyard), the alarms
can be displayed in groups of five (A2 to An) by pressing the "ALARMS" key again.
All alarms are always displayed in reverse order of their occurrence. The alarm gener-
ated last is therefore located in the first line of the alarm screen. As long as at least one
alarm is active, the red LED "Alarm" to the right of the display lights up.
