BRAIN 24 CONTROL UNIT
WIRE DIAGRAM
Wire connections shown in Fig. 1 are described hereunder:
Terminal No. Function Description
1-2 Motor 1 Connection, motor 1: 24VDC 120W max
3-4 Motor 2 Connection, motor 2: 24VDC 120W max
5-6 Flashing light Connection, flashing light 24VDC 15W max.
7-8 Lock Output, 12VAC/10W (5s) power supply for electric lock (7:0V, 8:+12V)
9-10 SCA/SRL
Normally open clean contact. Controlled by “SRL” logic.
With SRL logic Off: SCA contact, open gate indicator.
With SRL logic Off: it performs the contact function of the courtesy light control, see table
of logic.
11-12 24 Vac/dc
Output, accessory power supply, 24VAC/0.5A max.
IMPORTANT: If the battery charger board CB.24V is installed, the output (without mains
power connected) has a 24Vdc polarised voltage.
Make sure the devices are correctly connected (i.e. 11:+24Vdc / 12:-0Vdc).
13 COM Common for limit switches and all control inputs.
14 SWO1 Input, OPEN limit switch, motor 1 (Normally closed contact)
15 SWC1 Input, CLOSE limit switch, motor 1 (Normally closed contact)
16 SWO2 Input, OPEN limit switch, motor 2 (Normally closed contact)
17 SWC2 Input, CLOSE limit switch, motor 2 (Normally closed contact)
18 PHOT Input, photocell activated in both opening and closing phases
19 PHOT C Input, photocell activated in closing phase only
20 STOP Input, STOP push-button (Normally closed contact)
21 OPEN Input, OPEN push-button (Normally open contact).
22 CLOSE Input, CLOSE push-button (Normally open contact)
23 PED Input, push-button for pedestrian use (Normally open contact), it controls the complete
opening of motor 1
24 Step-by-Step Input, step-by-step push button (Normally open contact)
25 COM Common for all control inputs.
26-27 BAR
Input, sensitive edge contact
Resistive edge: “DAS” Jumper closed
Mechanical edge: “DAS” Jumper open
When the edge is activated, the gate movement is stopped and reversed for about 3s.
28-29 RX 2ch Output, second radio channel of the receiver.
N.O. contact, voltage-free.
30-31 Antenna Connection to the insertable radio receiver card (30-signal/31-screen).
JF1-JF2 24VAC/dc Input, 24VAC/24VDC power supply.
If buffer batteries are used, connect the CB.24V card (in option) as indicated in the table.
PROGRAMMING
The programming of the various functions of the control unit is carried out using the LCD display on the control unit and setting
the desired values in the programming menus described below.
The parameters menu allows you to assign a numerical value to a function, in the same way as a regulating trimmer.
The logic menu allows you to activate or deactivate a function, in the same way as setting a dip-switch.
Other special functions follow the parameters and logic menus and may vary depending on the type of control unit or the software
release.
TO ACCESS PROGRAMMING:
1 – Press the button <PG>, the display goes to the first menu, Parameters “PAR”.
2 – With the <+> or <-> button, select the menu you want (PAR>>LOG>>NMAN>>RES).
3- Press the button <PG>, the display shows the first function available on the menu.
4 - With the <+> or <-> button, select the function you want.
5 - Press the button <PG>, the display shows the value currently set for the function selected.
6 - With the <+> or <-> button, select the value you intend to assign to the function.
7 - Press the button <PG>, the display shows the signal “PRG” which indicates that programming has been completed.
NOTES:
Simultaneously pressing <+> and <-> from inside a function menu allows you to return to the previous menu without making any
changes. Hold down the <+> key or the <-> key to accelerate the increase/decrease of the values.
After waiting 30s the control unit quits programming mode and switches off the display.
