The unit serves to indicate engine alarms and displays in optical and acoustic form. 

Up to

two engines can be monitored simultaneously

.

The display unit is activated when the ignition is turned on. If there is an alarm not only
the relevant LED but also the integrated buzzer is activated.
In the event of a pre-alarm, only the LED of the associated measuring point flashes. In
the event of a master alarm, the “Alarm” status LED is also activated. If the alarm is a
shutdown or slowdown alarm, the corresponding status LED “Engine slow down” or “En-
gine stop” also lights up.
When the acoustic acknowledgement (Horn Quit key) has been pressed, the integrated
buzzer switches off. With optical acknowledgement (Optic ackn), the flashing LED
switches to being continuously lit. When the fault has been eliminated the LED goes out.
The “RESET” button must also be pressed in the event of alarms which have resulted in
automatic engine shutdown or slowdown by the MMDS central unit. This function is en-
abled for a shutdown alarm only when the engine is at a standstill and for a shutdown
alarm below a speed of 800 rpm.

Dimming

All alarm LEDs are dimmed automatically irrespective of the brightness of the surround-
ings. This function is performed by a photoelement integrated in the front panel.

The lettering is back-lit and can thus be read at night too.
