Guarding a wood processing center with SLSR 46B Single Light Beam Safety Devices and TNT 35 Test Monitoring Unit
TNT 35 is a Test Monitoring Unit for the periodic testing of "testable" optoelectronic protective devices. Both components, sensor and TNT 35, form an AOPD in accordance with IEC/EN 61496-1, -2. Up to 6 type 2 sensors can be connected to the TNT 35 via a series connection. In addition to testable Leuze electronic type 2 Single Light Beam Safety Devices, type 2 Single Light Beam Safety Devices of the MLD 300 series can also be connected. The machines functional sequence remains unimpaired by the periodic internal function tests.
