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 4 Fig. 1).
Following fig. 1, make the electrical connection on the terminal
block.
Make sure that the correct power supply is selected by means of the
jumper (detail 1 Fig. 1).
The contact of the receiver photocell is normally closed (N.C.) when
powered and aligned with the transmitter.
If the contact needs to be normally open (N.O.), remove the
electronics from the plastic support and cut track A and carry out
welding B as shown in figure 4.
In order for the photocell to work correctly, avoid installing the
receiver close to spotlights, Triac electronic controls or other
sources of electric disturbance.
OPTIC ALIGNMENT
The VEDO180 photocells can be horizontally adjusted to over
180°.
Slacken screw 8 in figures 1 and 2, rotate the internal parts of the
photocells until they are out of alignment, then carefully tighten the
screws.
The red led of the receiver (detail 7 fig. 1) is off when the photocells
are aligned.
Slight vertical alignment differences are compensated by a self-
centring lens system.
SYNCHRONISM
The beams from a pair of photocell in a system with two pairs of
photocells that are close together could interfere on the other pair
causing malfunction; in this case it is advised to activate the
synchronism
if an alternating power supply is available.
To activate the synchronism, cut the jumpers in both transmitters
(detail 5 fig. 1) and invert the power supply on one of the photo-
cell pairs, see figure 5. If it is not possible to activate the synchro-
nism, then avoid positioning the two receivers on the same side
and the transmitters on the other, and alternate the receivers and
transmitters, fig. 6.

prior to having isolated the power supply.
The non-observance of the said instructions could prejudice the
correct function of the equipment.
