EDR Safety Concept: Notes
A pre-drive check of the EDR system is carried out every time the ignition is switched On (KL 15). The MS S52 control module briefly opens the throttles and checks the following:
- The zero set point of the feedback potentiometers - throttle valve closed position.
- Free movement of the throttle valves.
- Operation of the EDR actuator motor.
- Operation of the return springs in the EDR actuator motor.
