Activated Activated All. Restart interlock of the C 4000 handles
the reset function (see “Reset” below).
Always configure the application with restart interlock!
Ensure that there is always a restart interlock. The C 4000 is unable to verify if the restart
interlock of the machine is operable. If you deactivate both the internal and the machine’s
restart interlock, the operators of the machine will be at an acute risk of injury.
The electrical connection of the reset button is described in chapter “Reset button” on
page 51.

You can indicate the status “Reset required” using a signal lamp. The C 4000 has a dedi-
cated output for this purpose. The electrical connection of the signal lamp is described in
chapter “Connection of a signal lamp to the output Reset required” on page 51.
You can define whether the operator must press the reset button, or press and release it
to start the function. If you configure Press, then the reset is performed before the
operator releases the reset button again. This can be useful if you want, for example, to
use a two-hand control unit also as the reset button for the safety light curtain.
Never configure Reset after press if it is possible to stand behind the light curtain!
Reason: If pressing the reset button (without releasing it) is sufficient as the reset signal,
then the safety light curtain cannot differentiate the operation of the reset button from a
short-circuit to 24 V. In case of a short-circuit, the light curtain would be inadvertently
reset. In this case the operator would be in serious danger.
