HEADY 24 3B CONTROL UNIT
AUTOSET FUNCTION
IMPORTANT: The control unit is equipped with the Autoset function to automatically set the main functioning values based on the type of
installation.
The AUTOSET function must be repeated at every function parameter change or upon change of automation conditions. See the AUTO
menu for further information.
WIRE DIAGRAM
Wire connections shown in Fig. 1 are described hereunder:
Terminal No.
Function Description
1-2 Motor 1 Connection, motor 1: 24VDC 2.5A max
3-4 Motor 2 Connection, motor 2: 24VDC 2.55A max
5-6 Flashing light Connection, flashing light 24VDC 15W max.
9-10
SCA/
PHOTO TEST/
2 CH
Normally Open, voltage-free contact, configurable as open gate indicator light, photocell test or
second radio channel (see Fig. 4).
For use as “Open gate indicator” the TEST1 and TEST2 logics must be OFF
For use as photocell test it is sufficient to activate one or both TEST logics and connect the
photocells as indicated in Fig.3.
11-12 24 Vac/dc
Output, accessory power supply, 24VAC/0.5A max.
IMPORTANT: If the battery charger board 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).
13-25 COM/ENC+ Common for limit switch and all the command inlets or encoder power supply.
14 SWO1/ENC1 Motor 1 OPEN limit switch input (N.C. contact) or Motor 1 Encoder connection.
15 SWC1 Motor 1 CLOSE limit switch input, (N.C. Contact)
16 SWO2/ENC2 Motor 2 OPEN limit switch input, (N.C. Contact) or Motor 2 Encoder connection.
17 SWC2 Motor 2 CLOSE limit switch input, (N.C. Contact)
18 PHOTO/BAR
Input, photocell activated in both opening and closing phases
As an alternative, the PHOTO input can be used to connect a safety edge (see BAR logics).
19 PHOTC Input, photocell activated in closing phase only (Normally closed contact)
20 STOP Input, STOP push-button (Normally closed contact)
23 PED
Input, pedestrian push-button (N.O. (Normally Open) contact). It controls the total opening,
motor 1.
24 Step-by-Step Input, step-by-step push button (Normally open contact)
26 ENC- Input for GND Encoder connection (see Fig.2).
31-32 Antenna Connection to the built-in radio receiver card (31-signal/32-screen).
+ / - 24VAC/dc
Input, 24VAC/24VDC power supply.
In case of use of plug batteries connect the battery charging card as indicated in the specific
installation instructions.
U11
CONFIGURATION
MEMORY
Extractable Eprom Memory. Contains all the control unit configurations (logics, parameters, etc.),
including the radiotransmitters. In case of faults it is possible to extract Eprom and insert it into
a different control unit, avoiding reprogramming.
ENCODER WIRING
In case the motor is with Encoder and one wished to connect it to the control unit, carry out the connections indicated in Fig.2, in this case
the SWO1 and SWO2 inputs may not be used as Limit switch inputs.
It is not possible to use the Encoder and the closure Limit switch simultaneously.
Leave SWC1 and SWC2 shorted.
TO CHECK CONNECTIONS
1) Cut-off power supply.
2) Manually release the wings, move them to approx. half-stroke and lock them again.
3) Reset power supply.
4) Send a step-by-step control signal by pressing the <-> push-button.
5) The leeaves must move in OPENING.
In case this does not happen, it is sufficient to invert among them the motor run wires. (1<>2 for M1 motor, and 3<>4 for M2 motor) and,
if used, the relative Limit switch inputs (14<>15 for M1 motor, and 16<>17 for M2 motor).
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.
