Alignment aid
During installation, the DSM can provide an adjustment aid for optimal align-
ment of the emitter to the receiver.
If the sensor detects an area of air (yellow LED is lit) the DSM will begin to
display the intensity of the measured amplitude signal after 3 seconds:
If the signal is weak, the yellow LED will flash at a slow rate
As the intensity of the signal increases, the rate at which the LED flashes be-
comes faster
At optimal alignment (maximum signal intensity), the yellow LED is conti-
nuously lit.
The single sheet function (green LED) and double sheet function (red LED)
continues to be active. This makes it possible to check for correct functionality
of the double sheet control.
6.6.2
Program selection
In the program selection mode, the current program is displayed by the green
LED (number of flashing pulses = program number). Applying the adjustment
input (PK) to +U
B
(for > 500 ms) causes the next program to be selected in
cyclic sequence (program 1 follows through to program 4).
