10 Single/Double Break function
This control function can be used on small press machines where the operator is performing a loading and/
or unloading cycle manually.
NB!
– The feedback input must be a NC contact, providing a high to low transition when the machine head is
in the safe position and the operator can enter the hazardous zone.
– As long as the safety outputs are ON, an additional interruption of the protective f ield will result in an
interlock situation.
– A manual restart is necessary to start the single/double break function sequence again after power on
or any other interruption of the protective f ield while the machine is working.
– Input from restart and/or feedback must be longer than 300 ms.
– Minimum time of interrupting the protective f ield is 300 ms.
– Load/unload must be completed within 30 s after manual restart or after end position reached.
