SUGGESTED LOOP SENSOR LOCATIONS
FREE EXIT ON VEHICLE APPROACH
Gate will open when sensed by open loop and then close once all
loops are cleared if the close timer is on. Close input can be used
to close gate before timer expires (Figure 1).
Terminal #1, 2, and 3 are open inputs.
Terminal #5 is safety input.
Terminal #8 for shadow loop.
ENTRY WITH ACCESS CONTROL DEVICE
Gate will open when activated by an access control device. When
timer expires (if used), gate will close (Figure 2).
Terminal #5 is safety input.
Terminals #1, 2, and 3 are open inputs.
Terminal #8 for shadow loop.
DUAL DIRECTION AS ENTRY AND 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).
Terminal #1, 2, and 3 are open inputs.
Terminal #5 is safety input.
Terminal #8 for shadow loop.
Safety and open loops should be 4' from each other and from
the gate leaf to avoid loop cross talk and false detection of
gate.
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:
Use safety pressure sensing edges to
prevent entrapment.
RECOMMENDATION
3:
Install
ALL
access control devices
within view of gate.
