ELECTRICAL CONNECTIONS
The LEDs in this block indicate whether the equipment is working by checking the solenoid
outputs. The L19 and L20 LEDs turn green continuously when the solenoid is locked, and they
must turn off in free mode or during passing.
The L8 LED in coin-operated turnstile models show whether the coin unit has an external
+12V power supply connection.
The most important LEDs in this group are sensor LEDs. The operation of 2 direction sensors
located on the mechanism is controlled by these LEDs. The SensA and SensB LEDs are on when
the turnstile arm is in the middle position at idle, and they are all turned off when sensor disc
passes through the sensors while the turntable arm rotates. If the sensor LEDs are all off or on
during arm rotation, there may be a malfunction in the sensors or connection points.
In very dusty environments, the inside of the sensors can be cleaned first with a fine brush
and then with a damp cloth.
4 LEDs (Ain, Bin, Oin, Emr) indicate whether the external inputs are working or not. The
emergency input LED (Emr) must be permanently on unless there is an emergency. Ain, Bin, Oin
will be on as long as there is a signal in the input. If these LEDs on 3 inputs are always on, it
means that NC "normally closed" contact signal is connected to external inputs or that there is a
connection error.
There is a dry corac relay output in the direction of pass after the arm rotation. The LEDs
placed in front of these roles are turned on and off together with the 500mS relay after passing, so
that it is understood that the relay is working and there is contact.
The LEDs in this group show the operation stop of the control LEDs at the entrance and exit
of the turnstile. When the corresponding LED is on, it is understood that the guiding LED is
working. Red / Green LEDs are used for direction A and direction B.
L21 LED is used in turnstiles with drop arm option. It turns on when the arm dropping motor
is powered, and remains off at the other time.
