5.6.3 Start/restart interlock (RES)
When accessing the protective field, the start/restart interlock ensures that the safety sensor remains in
the OFF state after the protective field has been cleared. It prevents automatic release of the safety circuits
and automatic start-up of the system, e.g. if the protective field is again clear or if an interruption in the
voltage supply is restored.
The
start/restart interlock
has two functions:
• Start interlock
• Restart interlock
Using start/restart interlock
In addition to the safety sensor you must also install the reset button. The machine operator starts the
machine with this reset button.
DANGER
Risk of death if start-up is operated unintentionally!
Ensure that the reset button for unlocking the start interlock cannot be reached from the danger zone.
Before unlocking the start interlock, make certain that no people are in the danger zone.
For access guarding, the start/restart interlock function is mandatory. The protective device may
only be operated without start/restart interlock in certain exceptional cases and under certain
conditions acc. to ISO 12100.
