DCF
INSTALLATION
Make connections as shown in Fig. 1 (RX) Fig. 2 (TX). Secure and power the photocell 12 - 24 Vac-dc.
Power the photocell and adjust the angle as required. Cover the photocell with the front part and secure
with the screws provided. Pass across the photocell range several times, to check relay response.
FUNCTIONING
The DCF180DB photocell has been designed mainly for use with sliding gates, which eliminates the need
for a mobile frame. The device can also be used as a normal photocell in all cases where the transmitter
cannot be wired. The receiver must be positioned so that it is not disturbed by other photocells.
Transmitter operation
The transmitter has a jumper (J1) for power selection. To decrease the photocell range (down to 10 m)
open the jumper(J1). The flashing red LED L1 indicates proper transmitter operation.
The transmitter must be powered with 3V alkaline batteries. Each battery lasts on average 24 months in
normal power conditions (jumper (J1) disabled) or approximately 12 months in high power conditions
(jumper enabled). This duration is valid for optimal climatic conditions and optimal conditions of
use; variations in climatic conditions and improper use will reduce battery life.
Receiver operation
The receiver has 2 LEDs. The first LED (L1), indicates proper signal reception (the signal is being received
if the LED is on ), while the second LED (L2) only flashes when the signal is present (otherwise it is off). The
time the LED is on indicates signal quality. So the longer the LED is on, the better quality signal.
The receiver must be powered with a 12 or 24 V DC (check polarities are correct), or AC power supply.
If this photocell is used for a range of less than 2 m, the lens should be removed and the J1 power jumper
on the transmitter opened.
IMPORTANT: transmitters of other photocells must be positioned so that their band does not
directly face the receiver of the battery-operated photocell. If the above is not observed, normal
operation is not guaranteed.
