Reset
IMPORTANT
The reset function is often also called "preparation for restart." In this user
manual, the term Reset is used.
If you want to activate the restart interlock on the SafeZone Mini device
(internal) and also a restart interlock on the machine (external), then each
restart interlock has its own control switch.
After operating the control switch for the internal restart interlock (with
protective field unoccupied) the following occurs:
• The SafeZone Mini device switches its OSSDs to the ON state.
• The status indicator (
green.
The external restart interlock helps prevent the machine from restarting. After
resetting the SafeZone Mini device, the operator must press the control switch
to restart the machine controller.
ATTENTION: Verify that the correct sequence is followed.
The controller must be realized such that the machine only restarts if the
SafeZone Mini device is first reset and then the control switch for restarting
the machine controller is operated.
Reset Signals
If the SafeZone Mini device is operated using the ¡§With restart interlock¡¨
function, then after a protective field infringement and the subsequent clearing
of the protective field, it requests a reset signal from the control system (reset
required).
ATTENTION: The reset signal must be safety-related (single failure proof).
