FOTO30SDE
1. GENERAL DESCRIPTION
The photocell FOTO30SDE has been designed and created for use on power operated doors (gates, doors,..). It has autotest function,
usable with control units able to manage it (e.g. EURO1MF or EURO2MF). The autotest function is carried out as follows: before any
manoeuvre the station inhibits the transmitter by sending a voltage between +5 and +24 V dc on terminal N° 3. The absence of the
infrared beam thus brought about generates, with a 20 ms. delay, opening of the receiver's N.C. contact. The station checks that the
described procedure is properly carried out before each manoeuvre. It complies with european directive 98/336/EEC (EMC).
2. APPLICATIONS

6. FUNCTIONING
Align the beam with the receiver using the relevant adjustment screws "A" (fig. 2) on the receiver and transmitter. Interruption of the
infrared beam generates opening of the normally closed contact of the relay on the receiver and the turning off of the red LED.
7. NOTES
Alignment is checked by voltmeter measuring of tension at the receiver test-point (fig.3). This value varies in accordance with various
parameters, among which the distance between the photocells. The higher the voltage value at the test-point, the better the alignment.
This value can range between 0 and 5 Vdc.Optimun voltage should be between 0,5 and 0,6 Vdc.
