CP.BULL8 CONTROL UNIT
WIRE DIAGRAM 
Wire connections shown in Fig. 1 are described hereunder:
Terminals Function Description
L/N Power supply 
CP.BULL8: Input, 230Vac 50Hz (L-Phase/N-Neutral)
CP.BULL8 115: Input, 115Vac 60Hz (L-Phase/N-Neutral)
GND GND Earth (compulsory)
ANT/SHIELD Antenna
Connection of the antenna to the integrated radio-receiver module
(ANT-signal/SHIELD-screen).
COMMON +12V Common for control inputs.
PP Step-by-Step
Input, step-by-step push-button (N.O. contact)
Presettable as Input, OPEN with OPCL logics.
PED PEDESTRIAN
Input, pedestrian push-button (N.O. contact). It controls the partial opening, 
configurable through parameter TPED. At end of TCA time (if activated), closure 
control signal is sent. Presettable as Input, CLOSE with OPCL logics.
STOP STOP Input, STOP push-button (N.C. contact)
PHOT O PHO
Input, (N.C. contact) for safety devices (e.g. photocells).
During closure: if the contact is opened, the motor stops. With OPCL logics, when 
the photocell is no longer obscured, the motor reversion occurs (gate opens).
During opening: if the contact is opened, the motor stops. with OPCL logics When 
the photocell is no longer obscured, the motor restarts opening.
PHOT C PHA
Input,  (N.C. contact) for safety devices (e.g. photocells).
During closure: it can be preset by PHTC logics.
During opening: it can be preset by PHTC logics.
+12V COMMON Common for control inputs.
BAR/BAR
SENSITIVE 
EDGE
Input, safety edge (Normally Closed contact).
Resistive edge: Jumper “DAS” closed
Mechanical edge: Jumper “DAS” open 
If the edge is activated, the gate stops and a movement reversion occurs for about 
3 sec.
If the edge is not in use: Jumper “DAS” open, jumper between terminals BAR/
BAR.
SCA 
Service light 
RX 2° Ch
PHOTO TEST
Free, N.O. contact. Presettable as: 
- SCA (open gate indicator lamp): open contact when gate is closed, 
fast flashing light when gate is closing, slow flashing light when gate is 
opening and closed contact when gate is open. See wire diagram,  Fig.2).  
(Logics 2CH:OFF, SERL:OFF, TST1:OFF, TST2 :OFF);
-  Timed service light (see SERL logics and diagram in Fig.2);
-  Output, second radio channel (see 2CH logics and diagram in Fig.2);
-  PHOTO TEST to power the transmitters of photocells in TEST mode (see TST1, 
TST2 logics and diagram in Fig.3).
