Enabling passage through tension pulse is shown in the image below. It is necessary
to observe the polarity of the Vcc voltages and to use an external resistor for high
voltages (110V and 220V).
The control board also has inputs for optical sensors (CN11) that monitor rotation
without mechanical wear, and two opto-isolated inputs to clear the
CATRAX Master
if required.
6.7. Outputs
2
CATRAX Master's
board has outputs for return signals, electromagnets, pictogram,
collecting box, and sound alarm.
6.7.2.1 Return signals
Return signals indicate the moment and direction of passage and are originated at the
relay
–
normally open contact (NO) or normally closed contact (NC). Connect the
outputs according to the image below:
6.7.2.2 Electromagnets
Electromagnets are activated for blocking the turnstile. Opposite to the traditional
solenoids, electromagnets do not cause abrasion between the coil and the locking
device, avoiding malfunctions. Moreover, the activation is done through a transistor,
and not a relay, avoiding the electromagnet to be blown due to the
“
contact wielding
”
(there is no mechanical wear).
6.7.2.3 ound alarm
S
The sound alarm output is activated by a NPN transistor (maximum 500 mA) every
time that
:
CATRAX Master
-receives a clearance signal (two short rings)
-is not cleared and is forced during 1 second (1-second rings)
-is stuck mid-turn for over 2 seconds (1-second rings)
