5.5 Control card terminal descriptions (XL9)

XL9 terminal has direction A and B pass relay
contacts. (Figure 5.8) Relay contacts are
normally open (NO) when the turnstile is at
idle.
The pins 2 and 3 of terminal XL9 are
connected to the relay RL1. The relay RL1 is
active in passing to direction A. The pins 4 and
5 of terminal XL1 are connected to relay RL2.
The relay RLw is active in passing to direction
B.
The signal duration of the relays giving the
pass information is 500mS. The corresponding
relay pulls and releases at 500mS in each pass.
The normally open (NO) and common (COM)
poles of the RL1 and RL2 pass relays are
removed in the factory as standard. If normally
closed (NC) contact outputs are to be taken, J3
and J4 jumper should be removed from the
normally open (NO) side, and connected to the
normally closed (NC) side.
