When the unit is on, an alarm icon flashes
and the alarm message appears. The possible alarm messages are listed below:
NOTE
The alarm relay switches status for all alarms.
7.10.2 Alarm relay
The Electronic Control Unit has an alarm signalling relay. Its contact is closed during normal operation and is opened in the
case of an alarm or a power blackout.
Refer to the wiring diagram for the relative connections.
In TAEevo Tech MINI 08-10 models a green light remains on to indicate that there are no alarms in the unit.
If an alarm occurs, the light turns red to indicate its presence.
