.2.1
The controller is assembled on
board
(104х68) and designed for installation inside the
turnstile body or power supply box. The controller appearance is shown in
Figure 6
. 19 LEDs are
installed on the controller board. Their purpose is as follows:
•
LED “POWER” initiates availability of power supply voltage 5V;
•
LED “OPERATE” initiates operability of microprocessor;
•
7 LEDs initiate state of outputs for peripheral connections “OUT1» ÷ «OUT7”;
•
3 LEDs “SENSOR” initiate state of rotor position sensor;
•
LEDs «RX» and «TX» initiate respectively reception and transmittance in serial port.
40 terminals are installed on the board: 14 of them are designed for external connections, the rest
are designed for connection to the turnstile units or are standby.

Description of operation
The controller operates according to the program entered into microprocessor memory. The
turnstile mechanism and LED displays are controlled according to control commands and status
of rotor position sensors based on the logic downloaded into program. Control commands can be
transmitted via RS485 (from control panel) or logical inputs (by closing and opening of inputs
“INP1” ÷ “INP5” on “GND”).
The controller (along with the turnstile) can be in the INITIAL STATE (closed for access) or in
the following access modes:
