SIMOTION Safety Unit (AP) - Edition 06.2003
2.2.2
Single stroke (operating mode 2)
Definition
Pressure must be maintained on the two-hand buttons for activating the ram until
the hazardous closing movement is completed (just prior to the BDC). The press
then automatically moves back to the TDC and comes to a standstill. The press
can also be activated using a foot switch. In this case, however, suitable safety
measures (safety gate, light curtain) must be implemented that either make it
impossible to reach into the hazardous area with the hands during a closing
movement or that cause the machine to come to a standstill in the event of such an
action.
The same applies if the "Transfer through input terminal" parameter is selected for
the "Transfer of START command".
