Protective field interruption
The safety outputs of the TMC 66 are opened (green LED off, red LED on) if during
protection mode the light beam of the single beam safety light barrier is interrupted.
The restart interlock inside the TMC 66 becomes active and avoids an automatic restart of
the machine. The yellow LED displays the function of the restart interlock.
The TMC 66 is in waiting state and can be restarted by pressing the start button after the
protective field is free.

Modes with muting function
Eight muting phases can be differentiated if the TMC 66 is used with muting.
Phase 1: Activation of muting preparation through connection of the control signals
Phase 2: Activation of muting through interruption of Start 1
Phase 3: Single beam safety light barrier is interrupted
Phase 4: Continuation of muting through interruption of Start 2
Phase 5: Continuation of muting through release of Start 1
Phase 6: Single beam safety light barrier is released
Phase 7: End of muting through release of Start 2
Phase 8: Basic state is again obtained through deactivation of control signals
The following figures illustrate the muting procedure by using the single muting phases and
the corresponding display state.
