- Page 15 Adjusting additional electric equipment Note for split-range mode: To prevent the valves from overlapping when they are being adjusted, a dead band as shown in Fig. 9, for example, ±0.5 mA should be taken into account. Valve 1 would then be set from 11.5 to 4 mA and Valve 2 from 12.5 to 20 mA, the corre- sponding values also apply for V input sig- nals.
