Susteco BIGHANNA T120, Operation Manual, Page: 23 / 139

The magnetic safety switch has one closing and one opening contact. The contacts are monitored by
a safety plc. To avoid unauthorised operation of the switch it is only possible to actuate the switch
with a coded magnet. Other magnets, screwdrivers and tools have no effect on the switch contacts.
When the safety magnet gives a fixed green light the connection is ok. When there is a red light there
is no connection.
