6.3.1. Limitswitch sensors changing – Task N°7
The bollard is equipped with two limit-switch sensors (one at the top and one at the bottom) mounted into the casing
to 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.
See appendix N° NT-REG for more detail.
Check the fastening and positioning of each limit-switch sensor: they must never touch the magnet. Check that they
properly detect the bollard when in up and in down position.
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. Limit-switch sensor replacing kit is supplied with plastic rivets.
