Functional principle in setup mode
If the 3TK2810-1 safety-related speed monitor is switched to the setup mode (control of
terminal EA1), the output contact 13/14 closes immediately. If the machine speed is also
within the parameterized speed window, the output contact 23/24 closes.
If setup mode (control of terminal EA1) is selected, monitoring of the protective door contacts
is deactivated (sensor circuits T1/P1 and T2/P2). The protective door can now be opened by
an enabling command to the interlock magnets.
