Product description
3.4 Configurable functions
This section describes the functions of the V200/V300 safety camera system that can be
configured.
Test the protective device after any changes!
After each modification to the protective device or its connection, you must check the
whole protective device for effectiveness (see section 7.1 “Test notes” on page 42).
3.4.1 Restart interlock
The V200/V300 has an internal restart interlock. The dangerous state of the machine (1)
is interrupted on a protective field interruption (2), and is not re-enabled (3) until the
operator presses the reset button.
• If you use the V200/V300 without internal restart interlock, then you must implement
the restart interlock externally, i.e. machine-side.
• Do not confuse the restart interlock with the starting interlock on the machine. The
starting interlock prevents the machine starting after switching on. The restart interlock
prevents the machine starting again after an error or an interruption of the light path.
When using the V200/V300, you can implement the restart interlock in two different ways:
• with the internal restart interlock of the V200/V300:
The V200/V300 controls the restart.
• with the restart interlock of the machine (external):
The V200/V300 has no control over the restart.
