Rail Crossing Applications
Figure 6 : Reading the estimated inductance values
3. For each loop, insert the jumper on the loop detector so that they correspond to the
inductance value of the loop.
Refer to section 0 (
4. SLD4 Loop Inductance Link Settings)
5. In the Monitoring & Simulation menu in the SLD4 Configurator software, click on the
"Record All Vehicles" tab
6. Drive over each loop in question, at least five times. Each pass should result in a vehi-
cle record, which includes a vehicle profile. The respective loop indicator LED should
turn red when there is a car present on the loop.
