INSTALLATION
The PNL18 is supplied in an “open frame” format. It requires a weatherproof enclosure
before it may be operated outdoors.
Direction Pointing:
The DR600 radar used in the PNL18 is directional in nature. It may be configured
to detect and measure the speed of incoming, outgoing, or bi-directional traffic. It
then rejects traffic moving in the opposite direction (unless set to bi-directional).
Direction of detection is configured via the bits in the radar’s MO and MD
variables, or preferably, via the GUI. In the usual “speed sign” configuration the
radar is set to measure and display speeds of incoming vehicles and is the default
shipped from the factory.
Statistics are only gathered for incoming traffic when placed in incoming or bi-
directional mode. No statistics will be collected in outgoing mode.
To achieve optimal performance please follow a few simple rules:
PNL18 should be pointed into the direction of the oncoming traffic.
PNL18 should be placed along the size of the road to minimize the angle of the
oncoming traffic to the sign.
o
If it cannot be placed right along the side of the road, it should be pointed
at least 100-150 feet up the road into oncoming traffic.
The radar in the unit may pick up rotating fans, compressor blades, etc. Avoid
pointing it at any machinery containing moving parts.
PNL18 should be mounted at least 3 feet high from the ground for proper
operation and at least 6 feet high for maximum pickup distance
PNL18 utilizes 15
viewing angle LEDs. For maximum visibility of the digits the
sign should be pointed at the incoming traffic with better than 10
accuracy.
Alternatively, the sign may be oriented towards traffic to maximize the LED
brightness from the desired viewing location on the road. We suggest providing
an adjustable mounting bracket for your enclosure that will allow at least a
15
horizontal rotation to allow the user to make an adjustment during installation.
Recommended Enclosure for the PNL18:
The PNL18 display kit must be protected by a weatherproof enclosure for outside use.
The following needs to be observed for optimal performance:
1.
Any plastic cover or window in front of the unit may be mounted as close to the
LEDs as desired. However, please consider any potential damage from flexing
due to an external impact on the sign face (vandalism, etc.) being transferred to
