12.4_ CONNECTING THE RECEIVER AND TRANSMITTER CAPSULES
To prevent interference due to direct sunlight, it is advisable to position the receiver sensors on the side most sheltered from the sun’s
rays.

12.5_ TRANSMITTER AND RECEIVER SENSITIVITY ADJUSTMENT
Once the sensors have been positioned, their sensitivity must be regulated by
means of the potentiometer on the board. Proceed in the following way:
1) Calibrate the potentiometer depending on the distance between the
sensors (see figure alongside).
2) The sensitivity is correct if the leds of the sensors selected in the mini dip
are off.
3) If the leds are on, turn the potentiometer slowly towards the maximum
setting until the leds go out.
4) Check to make sure that the relative leds come on when the infrared beam
from the photocells is broken.
12.6_ OPERATING FAULTS
The photocell module constantly checks the photocells to guarantee their
reliable operation. In the event of capsule malfunction, the motherboard emits
one, two or three beeps according to which pair of capsules has generated the
malfunction. Moreover, in order to prevent the automatic door from being locked in the open position and to guarantee its proper closing,
the door slows down during the closing manoeuvre until the normal operation of the photocells has been restored.
12.7_
DOOR STOP WITH STOP BUTTON
A STOP button with N.C. contact can be connected between terminals FT3 and FR3 in order to stop the movement of the door.
In order to exploit this possibility it is necessary to enable FT3/FR3 on the photocell card and to make it operational as a door crash
sensor (see TABLES 1 and 2).
