IDEC SG2 Type 2 Hand & Body - Manual (Page 6)

A Keep the receiver in a steady position and set the emitter until the yellow LED ( SYNC) is OFF.
This condition shows the effective alignment of the first beam (synchronisation beam).
B Rotate the emitter, pivoting on the lower optics axis, until the yellow LED ( LAST) is OFF.
NOTE: Ensure that the green LED ( NORMAL OP.) is steady ON.
C Delimit the area in which the green LED ( ) is steady through some micro adjustments - for the first
and then for the second unit - so to have the maximum alignment (4) and then place both units in the
centre of this area.
D Fix the two units firmly using brackets.
Verify that the green LED ( ) on the RX unit is ON and beams are not interrupted, then verify that
the red LED turns ON if even one single beam is interrupted ( , condition where an object has
been detected).
This verification shall be made with the special cylindrical “Test Piece” having a size suitable to the
resolution of the device used.
E Switch OFF and ON the device in standard operating mode.
The alignment level is monitored also during device normal operation mode via display (see chapter 7.2
on the manual inside of the attached CD-ROM).
Once the curtain has been aligned and correctly fastened, the display signal is useful both to check the
alignment and show a change in the environmental conditions (occurrence of dust, light disturbance and
so on) via signal level monitoring.
DIAGNOSTICS FUNCTION
The operator can visualise the operating condition of the light curtains thanks to a one-digit display
positioned on both the RX and TX unit.
SG2-E also has four LEDs on the RX unit and two LEDs on the TX unit. The figure below shows all
signalling LEDs modes: OFF, ON and BLINKING.

The operator can evaluate the main causes of the system stopping or failure using the 7-segment display
and LEDs used to visualise the functions. For Receiver:
