1.
Knock out the PG hole that will be used to pass the wires through.
2.
Pass the body of the cable grip through the
PG hole and tighten the backing to attach the
cable grip to the housing.
Cable Grip
3.
Thread all wires through the cable grip and
into the housing.
4.
Turn off the power supply when connecting
the USVD-4X power wires to the terminal
block. The terminals are not polarity sensitive.
5.
Wire the USVD-4X according to the operator
instructions and the terminal block table.
6.
Configure the DIP switch to the pulse/presence and delay mode desired.
7.
Mount the USVD-4X perpendicular to the side of the vehicle at the location of desired detection
and 22-
24” above the height of the pavement surface where the vehicle is located.
If using multiple USVD-4Xs it may be necessary to place a barrier up to 24x
24” between the
sensors to prevent units from interacting.
8.
Adjust the sensitivity by rotating the sensitivity adjustment clockwise to decrease and
counterclockwise to increase (#4 in image on previous page).
•
In most applications it is unnecessary to reduce sensitivity.
•
If using multiple USVD-4Xs, it may be useful to reduce the sensitivity to reduce crosstalk.
•
Two test points to the right of the sensitivity adjustment labeled GND and SENS may be
used to measure the position of the sensitivity adjustment. 5V is the maximum sensitivity.

Solution
Constant detection
Solid material blocking
transducer
Increase the angle of the
housing to avoid detection of the
ground or other low objects.
Turn down the sensitivity by 1V
by rotating the sensitivity
adjustment counterclockwise.
Attach a multimeter to the GND
and SENS pins to the right of the
sensitivity adjustment to read
the change in voltage.
