INSTALLATION
Remove the photocell cover with a screwdriver as shown in fig. 3.
Position the transmitter and receiver in line with each other and fix the
plastic base with at least 2 screws through the fixing holes (detail 2 Fig. 1).
Following fig. 4, make the electrical connection on the terminal block.
Configure the receiver photocell contact as normally closed (N.C., fig. 1
detail 8b) or, if necessary, as normally open (N.O., fig. 1 detail 8a).
If only one pair of photocells is present on the system, the transmitter and
receiver dip-switches must be set to OFF.
See next chapter for systems with 2 or more pairs of photocells (max. 8).
In order for the photocell to work correctly, avoid installing the receiver
close to spotlights, Triac electronic controls or other sources of electric
disturbance.
SYNCHRONISM
On systems with more than one pair of photocells close to one another, the
rays of one pair may interfere with those of the others, leading to
malfunctions.
When using this type of photocell simply connect all transmitter terminals 3
to each other and set the dip-switches of each pair of photocells to the
same setting, but different from other pairs (dip-switch no. 4 must always
be set to OFF) as shown in figure 4.
At least one pair of photocells must have all dip-switches set to OFF.
