3.1 ST5 - supply voltage
In position ST5, SI 010 CNV can be set to either 230 V or 115 V supply
voltage:
• one jumper across the two pins in the middle = 230 V.
• two jumpers as shown in fig. 4 = 115 V.
If the converter is connected to 24 VDC, the configuration of ST5 has no
function.
Fig. 4 How to set SI 010 CNV to 230 V and 115 V
3.2 ST3 and ST4 - sensor inputs
The sensors are available in two versions with different output signals, either
0.5 - 3.5 V or 0.5 - 4.5 V. The converter is compatible with both signal types
which are configured in short-circuit positions ST3 and ST4.
Caution
The SI 010 CNV can be connected to either 230/115 VAC or
24 VDC. It must NOT be connected to both voltages.
