Applies to the voltage range between -30 V and +30 V.
2)
According to IEC 61131-2.
3)
The specified values are the switching voltage supplied by the safety light curtain. If higher voltages are
im
planted externally, the maximum value of 2.0 V can be exceeded.
4)
When active, the outputs are tested cyclically (brief LOW). When selecting the downstream controllers,
make sure that the test pulses do not result in deactivation when using the above parameters.
5)
Limit the individual conductor resistance to the specified values to ensure that the light curtain func‐
tions correctly, particularly that a cross-circuit between the outputs is safely detected. (Also observe
IEC 60204-1.)
The specified values apply to the total resistance of each wire including contact and connector resistan‐
ces.
6)
The supply cable must not be used to connect other loads with the exception of the senders.
