5.1 Operaonal modes
The nXDS pump implements three control modes:
▪ Manual Control Mode ‑ using buons on user interface panel.
▪ Parallel Control Mode ‑ via 15‑way D‑type logic interface connector on user
interface panel.
▪ Serial Control Mode (including Serial Interlock) ‑ via 15‑way D‑type logic interface
connector on user interface panel.
The Control Mode is determined by the way the pump is started. Once started, the
pump can only be stopped by the mode in which it was started, unless the power is
cycled by isolaon from the electrical supply.
