OPERATING MANUAL
PSEN op2H-A series
A. Hold the receiver in a stable position and align the transmitter until the yellow SYNC1
LED goes out. This state confirms that the first synchronisation beam has been
aligned.
B. Rotate the transmitter around the axis of the lower lens until the yellow SYNC2 LED
goes out.
C. For precision adjustment, make minor movements of the transmitter and receiver to
achieve the optimum quality
D. Attach both units firmly using the mounting brackets. Check that the LEVEL of the
receiver does not decrease in quality and that the light axes are not interrupted. Then
check that all LEDs on the LEVEL display go out, even if only one beam is
interrupted. This test is conducted using a test object TP-30 corresponding to the
resolution (see Chapter 2.2.5).
E. Switch off the light curtain pair and then switch it back on in normal operating mode.
The alignment level is also monitored by the display during normal operation (see
Chapter 8.1). Once the light curtain has been aligned and fastened appropriately, the
LED display proves perfect for checking the alignment and displaying any change in
the ambient conditions (e.g. dust).
