Gating sequence reset
If the CS switching signal is applied for more than 4 s without the protective field being interrupted, the de-
vice switches to protective mode and the OSSDs switch off. If there is then no protective field violation, the
RES signal can be used to start a new gating sequence.
• A new gating sequence can be started multiple times if still no protective field violation occurs after ap-
plying the RES signal.
• The gating sequence restart must occur within no more than one hour, otherwise the device switches to
an interlock state.
• It may be necessary to reapply the CS switching signal before initiating a new gating sequence.
