Operation indicators
The operation indicators serve as a function check during operation, as well as for the calibration and adjustment process
The following information is displayed:

Potentiometer for output pulse width(
)
This potentiometer allows the output pulse width to be modified in stages, whereby turning to the left / right effects an increase / decrease
of the output pulse width (left limit stop: Maximum pulse width = 512ms or right limit stop: Minimum pulse width = 0.5ms). If the
dynamic
pulse adaptation (DPA)
function is activated, the function of the potentiometer changes. See sections 4.3 and 4.5 for details regarding
setting of the potentiometer.
Sensitivity potentiometer (Sens)
This potentiometer allows adjustment of detection sensitivity. To increase / reduce sensitivity, turn the potentiometer to the left or right
accordingly. See section 4.3 for details.
Control button for calibrating the working distance (CAL)
Once mounted, the device must be calibrated to the specified maximum working distance. Push this button once to initiate the automatic
calibration process. See section 4.1 for details.
The settings will be saved even after power off/power on.
Control button for dynamic pulse adaptation (DPA)
Pressing this button will activate / deactivate the dynamic pulse adaptation DPA (see section 4.4).
The
DPA active
LED indicates that the DPA program is active when it remains illuminated.
In case of supply voltage breakdown the selected state is stored securely.

STATUS
1)
1) This indicator has
three
functions:
1.During installation, the device is calibrated to a specified working distance. The indicator is illuminated during the calibration process.
2.The indicator is active (illuminated) while an output pulse is being generated.
3.If no output pulse is generated within 3s, the device switches to standby mode.
This is signaled by a flashing LED.
