What does RTL and LTR mean?

The TCR traffic counters distinguish between 2 directions and must be placed to the side of the object movement.

• RTL means from right-to-left
• LTR means from left-to-right

RTL = objects which come from the right and disappear to the left. The left LED will pulse once in this case. LTR = objects which come from the left and disappear to the right. The right LED will pulse once in this case.

The directional indications are meant from the viewer's perspective towards the LEDs located under the service lid. Never the "view of the device" towards the road.
