SA02MA Control unit with microcontroller
The SA02MA control unit with microcontroller can be used with motors having a power not exceeding
750W.
Installation instructions.
a) The electrical installation and functioning logic must comply with current standards.
b) Keep the power cables (for the motor and power supply) away from the control cables (buttons,
photocells, radio). To avoid interference use two separate sheaths (see EN 60204-1 15.1.3).
c) Check all the connections again before supplying voltage.
d) Check that the Dip-Switch settings are as required.
e) The Normally Closed contacts which are not in use should be short circuited.
f) If the direction of the motor rotation is not correct, invert the ”OPEN” - ”CLOSE” wires of the motor.
Input/Output functions
(1) Antenna Signal
(2) Antenna Shield
(3,8) SCA= Indicator lamp, Open gate
(4) P.P.= Input, Step-by-Step push-button (N.O. contact).
(5) Stop= Input, Stop push-button (N.C. contact).
(6) FTC= Input, photocell receiver (N.C. contact).
(7) +V= Common, all control inputs.
(8,9) OUT24VAC= Output, 24Vac auxiliary power supply (100mA max.).
(10,11) ELS.= Connection to 12V Electric lock
(12,13,14) To secondary of the Capacitor
(15,16,17) To primary of the Capacitor
(18,19) INPUT 115VAC= Control unit power supply, 115Vac, 60Hz (keep to phase/neutral).
(20,21) Lamp= Flashing light
(22,23,24) APRE/CHIUDE/COM= To relevant terminals of Motor 2, at 115Vac, 60Hz.
It is mandatory to connect the Ground wire (yellow/green) on the motor frame.
(24,25,26) COM/CHIUDE/APRE= To relevant terminals of Motor 1 at 115Vac, 60Hz.
It is mandatory to connect the Ground wire (yellow/green) on the motor frame.
If the control for the pedestrian entrance is to be used, connect the normally open (N.O.) button between
the +V input (common of controls) and the pin between P.P. and STOP.
The control unit is equipped with a built-in radio module for the reception of both fixed code and vari-
able code remote controls at a frequency of 433.92MHz.
To use a remote control its data should be stored in the unit memory. This procedure is shown hereun-
der. The unit is able to memorize up to 14 different codes.
Dip-switch functions
DSW1= The operation of the “Step-by-Step button” and the remote control can be selected with this
Dip-Switch.
Off= ”OPEN” - ”STOP” - ”CLOSE” functioning
On= ”OPEN” - ”CLOSE” - ”OPEN” functioning.
DSW2= This enables or disables the automatic closure.
Off= Automatic closure disabled
On= Automatic closure enabled
DSW3= It enables or disables the multi-flat function.
Off= Multi-flat function disabled
On= Multi-flat function enabled
DSW4= It enables or disables the forewarning flashing light.
Off= Forewarning flashing disabled
On= Forewarning flashing enabled
Trimmer functions
TCA This allows the automatic closure time to be adjusted when this is enabled by positioning the
DSW2 Dip-switch on ON.
Adjustment can be from a minimum of 1 to a maximum of 250 seconds.
The minimum time is obtained by rotating the trimmer completely anticlockwise.
TL This allows the working time of the automation to be adjusted. If the limit switches fail, the soft-
ware protection will intervene after this time has elapsed. (Add about 4 sec. to the actual stroke
time of the automation).
