Alignment check
Once the photocells are powered, the LED flashing on
the RX receiver indicates the reception level:
Slow flashing LED: weak reception
Fast flashing LED: good reception
LED on: excellent reception.
If reception is not excellent, correct orientation of
the photocells.
Synchronism (PUPILLA only)
To avoid interference in the event of use of the two
pairs of close photocells, activate synchronism by
removing the metal gear NT2, highlighted in Figure
5, with a screwdriver or drill bit.
Synchronism works exclusively with 22÷30 Vac
power supply
with polarity inverted between the two
pairs as indicated in Fig. 7/8.
IMPORTANT: To prevent infiltration of humidity
and condensate phenomena, seal with utmost
care, using a silicone product. Seal both the cable
in the duct and the fastening base at the entrance
hole of the duct.
