the opening cycle, the operator stops moving.
The photocells should be installed about 50 cm (1.65 ft) above the ground (in
accordance with the manufacturer's recommendation), in such a way that the
both the transmitter and the receiver are aligned between each other. The
electrical connections must be as follows:
Terminal block 2: 15V (positive "+");
Terminal block 1: GND (negative "-");
Terminal block 4: FAB (Contact of the Photocell).
CAUTION: This control unit is compatible with any kind of photocell
(Normally Open, Normally Closed or Resistive). In order to set the pho-
tocell intended to be used, one must connect all photocells and press
the "RAMPA" (Deceleration zone) button, with all photocell aligned, i.e.,
with no obstacle between them. One can also calibrate the photocells
by using the PROG programmer (programming tool). To do so, one
must enter the "Calibration" function and press the "+" button on the
device's keypad.
There are LEDs used for checking the commands by the opening ("FA")
and closing ("FF") photocells.
The control unit acknowledges (recognizes) a pushbutton command when the
BOT Terminal block is connected to the GND, i.e., a pulse to the GND.
Terminal block 1: GND (Negative "-");
Terminal block 4: BOT (NO Contact).
There is a LED used for checking the pushbutton commands ("BOT").
2.11 – CONNECTING THE "ABR" OPENING-ONLY PUSHBUTTON
The control unit acknowledges an opening command when the "ABR" Termi-
nal block is connected to the GND, i.e., a pulse to the GND.
Terminal block 1: GND (Negative "-");
Terminal block 5: ABR (NO Contact).
There is a LED used for checking the pushbutton commands ("ABR").
2.12 – CONNECTING THE "FEC" CLOSING-ONLY PUSHBUTTON
The control unit acknowledges a closing command when the "FEC" Terminal
block is connected to the "GND" and then released, i.e., a pulse to the GND
and the the button must be released.
It makes it easier using the control unit in access control systems that use pho-
tocells or inductive loops to automatically close the gate or automatic barrier.
Terminal block 1: GND (Negative "-");
Terminal block 6: FEC (NO Contact).
There is a LED used for checking the "FEC" terminal block commands.
