5.6.12. Setting up Digital Inputs (Optional)
The Protocol Plus control can be run by external inputs wired to the control from an
external source such as a PLC or control panel switches (Figure 9). The external run
operation can Run, Hold or Stop profiles 1 through 7 (profile 8 cannot be operated
externally). See Table 14 for the inputs required for the desired operation.
18 If the controller does not have this feature, No is the only option.
