To configure the Two-Hand Control mute option, the TC actuators first need to be connected to the
Two-Hand Control function block in the Function View. Check boxes (blue square above) in the
Properties menu will display the names of all TC actuator input devices. Only those THC station
boxes that are checked will be muted.

Actuators TC1 and TC2 can initiate a two-hand cycle if the mute enable ME1 is not active.
ME1 must be active for the MSP1 mute sensors to keep the SO On after the TC1 and TC2 actua-
tors are in the Stop state.

Figure 39. Timing Diagram—Two-Hand Control Block with Muting
Two-Hand Control Activation on Power-Up Protection. The Controller’s two-hand control logic does not permit the
assigned safety output to turn On when power is initially supplied while the THC actuators are in their Run state. The THC
actuators must change to their Stop state and return to the Run state before the Safety Output can turn On. A Safety
Output associated with a Two-Hand Control device will not have a manual reset option.
