INSTALLING STANDARD 11-PIN BOX TYPE
VEHICLE DETECTORS
If standard 11-pin box type vehicle detectors are
to be used, perform the following procedure.
If there is sufficient space, install the sockets
in the control box; if not, then install them in a
separate external housing. Carefully consider
your peripheral connections. Any peripheral
device required for safe gate operation should be
attached 24VDC in case of an AC power outage.
Figure 53 is for general reference only.
NOTICE
If photo eyes are used to monitor vehicle traffic
instead of loop detectors, connect the photos
eyes using the same steps described below.
NOTICE
Box detectors with relays require five times
more power than HY-5A detectors. One HY-5A
detector draws about 0.005A. Consider HY-5A
vehicle detectors for DC and Solar powered
sites.
VEHICLE DETECTOR
1.
Connect 24 Volt power to the detector.
Connect Pin No. 1 to a 24VDC terminal and
Pin No. 2 to Common.
2.
Connect output Pin No. 6 to the Common
Bus and output Pin No. 5 to one of the four
detector terminal inputs (depending upon the
detector function required) on the Smart DC
Controller.
3.
If multiple detectors are used, route the power
wires and common wire from socket to socket
(daisychaining) rather than individually running
each wire to the same location. See Figure
The only wires that are separate are the
output wire to the Smart DC Controller and
the detector loop input wires.
NOTICE
Always keep the detector loop wires well
twisted at all places beyond the area of the
loop. The lead in portion should be twisted
to the detector to help mitigate problems
associated with electrical noise getting into
the loop wires. The wires should then be
encapsulated in the saw cut with a flexible loop
sealant. Refer to "Installing Vehicle Detectors
.
