BRAIN 24 control unit
The BRAIN 24 electronic control unit may be used for the control of 1 or 2 motors 24Vdc with power not higher than
120W+120W.
GENERAL WARNINGS
a) The electrical installation and the operating logic must comply with the regulations in force.
b) The leads fed with different voltages must be physically separate, or they must be suitably insulated with additional insulation of
at least 1 mm.
c) The leads must be secured with an additional xture near the terminals.
d) Check all the connections again before switching on the power.
e) The unused N.C. inputs must be bridged.
INPUT/OUTPUT FUNCTIONS
BRAIN 24 Control unit
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, ashing 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.
