8.4.9 Mode 2: Controlled Entry, Free Exit Mode
If IN4 and IN5 are active and the opening signal at IN3 is maintained
the barrier is setup for free exit (right) and controlled entry (left)
through an access control device.
The barrier is always closed and opens as soon as a person enters
the lane from the “free direction” or makes use of a valid ID card (or
other valid media) at the controlled exit.
If the passage is begun in the correct direction, so after releasing
the high-speed closing and interrupting the light barrier before the
card reader an OFF period of 2 s is set. In this time no wrong way
alarm occurs. Becomes a Safety light barrier active during the clos-
ing time, the time is after-triggered. This can be necessary because
of a rolling suit-case which is pulled afterwards
Direction left (entry):
-
Barrier End Display shows GREEN ARROW
-
Opening input Right is activated
-
Directional beams are active and evaluated based on the walk-
through direction
-
r.f.p.l. is being controlled
-
I.c.r.l. is being controlled
Direction right (exit):
-
Barrier End Display shows GREEN ARROW
-
Opening input Right enabled
-
Directional beams are active and evaluated based on the walk-
through direction
-
r.f.p.r. is on
-
I.c.r.r. is on
As soon one side receives, a valid opening pulse (directional
beams, access card reader, etc.) the end display on the opposite
side will change to a RED CROSS and all opening inputs from the
opposite side are disabled. Upon successful completion of a walk-
through, the end display changes to a GREEN ARROW and both
sides accept opening commands again.
If there is an opening impulse at the controlled side the gate opens
when the PE beam is free at the empty side.
