1.1.2 Alarm Outputs for Installation and Maintenance
There are also several alarm states to show the status of the system during start-up, fault,
or configuration.
•
At system start-up the buzzer display will perform the following start-up sequence:
Red visual warning -> Yellow visual warning -> On (green LED). Each visual
warning is accompanied by a beep. This confirms the visual and audio functions of
the buzzer display are working correctly.
•
If the system is not configured, the power/fault LED will illuminate red.
•
When the system self-diagnoses a fault with a sensor or vehicle data input, the
power/fault LED will illuminate amber.
•
When the buzzer display is powered but receiving no data, the power/fault LED will
flash alternately green and amber.
•
When the system is connected to the configuration software there will be a flashing
green light on the power/fault LED.
See the troubleshooting guide in Section 7.3 for dealing with these faults.
