The controller is switched to “SINGLE ACCESS IN ONE DIRECTION”, if in the INITIAL STATE
it receives “TO BE OPENED А/В" command (i.e. active level of signal is sent to input “INP4” or
“INP5”). In this case the turnstile is open within action period of signal. The command can also be
sent delay of WAITING FOR START OF ACCESS.
Sequence of the controller operations after reception of "TO BE OPENED А/В"command is as
follows:
•
Delay of WAITING FOR START OF ACCESS is initiated (Factory setting 5 sec.).
•
Controller deenergizes solenoid and rotor is unlocked in the relevant direction.
•
LEDs are switched from red to green according to the authorized access.
Then two alternatives of events are possible.
1) First alternative: If within active status of "TO BE OPENED /В" (“INP4”/“INP5”) or during
delay of WAITING FOR START OF ACCESS rotation of rotor is not started, then controller is
reset to ”INITIAL STATE”;
2)Second alternative: If in the above mentioned cases rotation of rotor is started, then further
behavior of controller depends on angle of rotor rotation.
•
When rotor is rotated to 6º, LEDs are switched from green to red, indicating that access is
occupied. Output signal START OF ACCESS "А/В" ((“OUT1” or “OUT2”) becomes active.
•
When rotor is rotated to 54º the output signal “START OF ACCESS "А/В” (“OUT1”or “OUT2”)
is removed. Delay of WAITING FOR START OF ACCESS is reset;
•
When rotor is rotated to 64º, ACCESS DETECTION (OUT3 or OUT4) signal is generated.
•
When rotor is rotated to 120º, OCCUPIED ACCESS А/В and ACCESS DETECTION(OUT3 or
OUT4) signals are reset and then availability of "TO BE OPENED А/В" (INP4 or INP5)
command, conforming to the current, is checked. If by this moment the command remains active,
the controller switches to FREE ACCESS mode and if not, then it is reset.
1.6.3.3.2 FREE ACCESS IN ONE DIRECTION
In this mode rotor can easily rotate in free access direction . In the FREE ACCESS mode green LED
of the relevant direction is blinking.
The controller is switched to this mode in two cases:
•
First: when "TO BE OPENED А/В" (input INP4 or INP5) command is maintained in active
status at the moment of rotor crossing the point 120º upon termination of SINGLE ACCESS.
•
Second: after reception of FREE ACCESS command in the relevant direction via RS 485.
After the controller
is
switch
ed
to FREE ACCESS mode, output signals of “OCCUPIED
ACCESS”, “ACCESS DETECTION” of the relevant direction are generated as described in Table
8.
Exit from this mode into INITIAL STATE is taken place after cancellation of "TO BE OPENED
А/В" command or reception of FREE ACCESS CANCELATION command via RS485. But it will
happen not instantly and only when rotor reaches one of the starting points 0º, 120º or 240º, i.e. if
free access
is
cancel
ed
during started access it will be completed as free.
