IDEC SG4 Type 4 Finger & Hand - Manual (Page 2)

 The presence of intense electromagnetic disturbances could jeopardise device operation. This condition
has to carefully evaluated with the support of the DATASENSOR Technical service.
 The operating distance of the device can be reduced in presence of smog, fog or airborne dust.
 A sudden change in environment temperature, with very low minimum peaks, can generate a small
condensation layer on the lenses and so jeopardise functioning.
 Reflecting surfaces near the safety light curtain light beam (above, under or lateral) can cause passive
reflections that can jeopardise functioning.
 The safety device must be installed at a distance which is major or equal to the minimum safety
distance S to ensure that the operator can not reach the dangerous area until the moving dangerous
object has been blocked by the ESPE.
The failure to respect the safety distance reduces
or cancels ESPE the protection function.
For more detailed information about calculation of safety distance,
please refer to the complete manual contained in the CD supplied.

ALIGNMENT PROCEDURE
The alignment between the emitting and the receiving units is necessary to obtain the correct functioning of
the light curtain.
A good alignment prevents output instability caused by dust or vibrations.
The alignment is perfect if the optical axes of the first and the last emitting unit beams coincide with the
optical axes of the corresponding elements of the receiving unit.
The beam used to synchronise the two units is the first after the connector. SYNC is the optics connected
with this beam and LAST is the optics connected to the last beam after the SYNC unit.
