5.5.1 How to use the pass relays
There are 2 directional pass relays on the turnstile control card. Normally open (NO) poles
of these relays are extended to terminal XL9. The pass information relay contact is available
separately for A and B directions. At each rotation of the turnstile arm to direction A, the A
direction pass contact 500mS is activated, and it becomes passive again. In the same way, every
time the turnstile arm rotates to direction B, the B direction pass relay is activated, and it becomes
passive again. A maximum of 500mA (30VDC) current can pass through the pass relay contacts,
external relays should be used if more current is desired. Directional pass relays work
independently of A/B direction opening and emergency inputs. They detect the rotation of the
arm, even if the turnstile is in A/B direction, free or emergency mode, and send the pass
information. Pass relays give a normally open (NO) contact output as standard, and if desired,
jumpers J3 and J4 can be switched from normally open (NO) to normally closed (NC) to obtain
contact information.
Directional pass relay can be used with the reader control system as well as for counter
connection if desired.
5.5.2 Pass relays and counter connection

Figure 5.9 shows the mechanical counter
connection using directional pass relays.
It is located on pin 1 of the XL9 terminal
(+ 24VDC), this output can be used as the
switching voltage to counters. For this
purpose, pins 1, 2 and 4 of terminal XL9
must be short-circuited.
Pin 6 of the XL9 terminal (GND) is
connected to the negative (-) poles of the
counters. The diode (1N4007), which is
connected in parallel to the poles of the
counter, must be fitted in order to prevent
interference. Note the direction of the diode
in the connection, as the reverse connection
may cause malfunction of the turnstile
adapter.
Finally, pins 3 and 5 of terminal XL9 are
connected to the plus (+) poles of the
counters. Once the connection is completed,
the corresponding counter will increase by
one (1) value at each turn of the turnstile.
