6.4.4 Examples of some configurations
1 - Configuration of controller to receive a relay pulse (normally open contact), clear the
turning and wait to turn for 10 seconds
2 - Configuration of controller to leave the clockwise direction always cleared and, when
the HAB2 (anti-clockwise) clearance signal is received, clear passage for undetermined
period
3 - Configuration of controller to clear the turning while the relay has the contact closed
and, as soon as the relay contact is open, remove clearance

6.4.3.2 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).
6.4.3.3 Sound alarm
The sound alarm output is activated by a NPN transistor (maximum 500 mA) every time
that
:
CATRAX Plus
-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)
Connect the outputs according to the following image:
