6.5. BUILT-IN HYDRAULIC MOTORIZATION CORRECTIVE ACTION DETAILS
6.5.1. Limitswitch sensors replacement – Task N°12
The bollard is equipped with two limit-switch sensors (one at the top and one at the bottom) mounted into the casing
using the components bracket. Each sensor transmits to the management system's PLC the information on the
bollard position and contributes to the access safe functioning. The limit-switch is a normally open contact.
The bollard head is equipped with a detection magnet.
Check the fastening and positioning of each limit-switch sensor: they must never touch the magnet. Check that they
properly detect the top and bottom of the bollard.
In case of malfunction, check the connections on the technical control unit and in the bollard and, if the problem
continues, replace the limit switch sensor.
