Figure 4-8 Discrete output circuit
The discrete outputs can be used to indicate a fault, to indicate filling in progress, or to control the
primary or secondary valves, as described in Table 4-10.
Note: Before you can assign a discrete output to valve control, the Fill Type parameter must be
configured. See Chapter 7 and Figure 7-3.
