WARNING!
Risk of electrocution!
Safe electrical isolation must be ensured for the external power supply that
generates the supply voltage. Failure to do so could result in electric shock.
The power supplies must comply with EN 60950-1:2006/A11:2009, EN
61558-2-6:11/1997.

Cascading
}
Base units from the configurable control system PNOZmulti can be networked. The
cascading output on one base unit is connected to the cascading input on another base
unit. In this way, one base unit can have direct access to a logic output and/or an input
on the connected base unit.
}
The base units can be connected in series or a tree structure can be built.
}
PNOZelog units may also be included in the network.
}
The cascading outputs may not be used to drive loads. The same also applies to out-
puts on PNOZelog units that are connected to cascading inputs on PNOZmulti units.
}
If necessary, a reset lock must be provided on each cascaded unit.
Example:
}
Delay between input I0 - cascading output Unit 1: 40 ms
}
Delay between input I0 - cascading output Unit 2: 40 ms + 40 ms
}
Delay between input I0 - semiconductor output Unit 3: 40 ms + 40 ms + 40 ms
}
Delay between input I0 - relay output Unit 4: 40 ms + 40 ms + 40 ms + 60 ms
