In addition to the speed signal, the following information is provided by varying the

length of the output pulses in Figure 3 (PWM modulation):

Airgap Warning range = Warning

Warning information is issued in the output pulse length when the magnetic field is

below a critical value. (E. g. the airgap between the Hall Effect IC and the target

wheel exceeds a critical value). The device works with reduced functionality.

Assembly position range = EL

EL information is issued in the output pulse length when the magnetic field is below a

predefined value (the airgap between the Hall Effect IC and the target wheel exceeds

a predefined value). The device works with full functionality.

Direction of rotation right = DR-R

DR–R information is issued in the output pulse length when the target wheel in front

Direction of rotation left = DR-L

DR–L information is issued in the output pulse length when the target wheel in front
