8.3 Selecting the valve sizes
When selecting a valve, the operator generally must ensure that no command value
and no enable is applied to the VT-MRPA1!
The desired valve size has to be selected by means of the rotary switch, see Abb. 4
item 4. While you make the settings, test jack “v“ outputs the selected rotary switch
position as a voltage value in 100-mV increments.
The following valve sizes are available.
