System Functions
4.8 Displays / Outputs (monitoring function)
By means of the digital PWM outputs and depending on the configuration, various signals can be displayed
and output.
Fault lamp (Pin 4 vehicle plug)
A red fault lamp must be placed where it is easily visible at the customer apparatus side. The fault lamp ser-
ves as a rough estimate of the fault that has occurred; here the following means:
!
Lamp 2 s on: Self diagnosis with switched on the voltage supply. Result: There are no faults.
!
Continuous light: There is a fault message; however the system is operational (possibly limited).
!
Flashing: Serious malfunction - engine will be switched off or engine cannot be started.
!
Blink code: Query malfunction locality by means of diagnostic button.
For detailed information see Chapter 7.1.
