The control unit has three main LEDs for indication:
l
POWER indicates power on. Flashes when low voltage.
l
WARNING indicates one or more* active alarm. Flash-
es when not acknowledged.
l

automatic stop. The LED is lit until the engine has
stopped completely.
Three of the buttons (START, STOP and CHANGE VIEW)
also contain LEDs. The LED in the START button is lit
when the engine is starting. The LED in the STOP button
is lit when the engine is stopping. The LED in the
CHANGE VIEW button is lit if more than one alarm is ac-
tive at one time.

ing LED will immediately start to flash/lights* and the
