1) If “none”, this specification is omitted.
2) Complete type codes and selection tables for the next-generation BCU4 and power module BCM400, see from page119 (Selection).
3) BCU..C with additional PCB for voltage distribution to the UV sensor for continuous operation. Can be used as a sub-distribution board
due to the low number of outputs. The new BCU4 (2019) has an adequate number of (parameterizable) inputs and outputs as well as
contacts. When making the replacement, check whether the additional sub-distribution board is still required.
4) If power management is implemented using the safety interlocks, this specification is omitted. Power management via phase (L1) = E1.
