8.8.3 Fault during the teach operation
The teach operation is cancelled in case of a fault:
> LEDs are flashing green/yellow with 8 Hz�
> The unit returns to the operating mode with unchanged settings�
Possible faults:
• Time error (teach time too long / too short)
• Internal sensor signal not clear
• Wrong output function: (→ 8.8 Parameter setting via the teach input)
• Process value too low (< 9 %, e�g� for powders), SPx/rPx must be set manually
(→ 8.1 Parameter setting via PC and IO-Link interface)�
9 Operation
When the supply voltage has been applied, the unit is in the operating mode�
It carries out its evaluation functions and switches the outputs�
Outputs OUT1 and OUT2 complement each other�
The following table shows the factory settings� In this state OUT1 = Hno
and OUT2 = Hnc�
► Check whether the unit operates correctly�
