FREE EXIT ON VEHICLE APPROACH
Gate will open when sensed by exit loop and then close once the
close loop is cleared. If the vehicle pulls up to the exit loop and
then backs away, it will close (Figure 1).
Space between loops will be 4' to 10'.
Terminal #7 is backaway (free exit).
Terminal #6 is close input.
ENTRY WITH ACCESS CONTROL DEVICE
Gate will open when activated by an access control device. When
vehicle passes and clears close loop, gate will close (Figure 2).
NOTE: If a second vehicle tail-gates and is sensed at the close
loop, gate will stop its closing motion until loop is cleared again.
Terminal #6 is close input.
Terminals #1, 2, and 3 are open inputs.
DUAL DIRECTION AS ENTRY OR FREE EXIT
Dual direction is a combination of both of the above
configurations to provide the ability for traffic to enter or exit in
the same lane (Figure 3).
Space between loops will be 4' to 10'.
DO NOT ALLOW CONTROL DEVICES TO BE WITHIN 10' OF GATE
OR OPERATOR
RECOMMENDATION 1: If vehicle detectors are used to open or
close the gate, use of the presence contacts are recommended.
Using the pulse contacts will REDUCE the gate’s safe operation.
RECOMMENDATION 2: If closing timer is to be used, use ONLY
on a dedicated free exit.
RECOMMENDATION 3: Close loop must be centered under gate
arm.
