Section 3 Operation External Inputs The front INT/EXT key enables external functions. Switching to INT on the display disables the external functions, allowing the front panel controls to operate the pump. When the INT/EXT key is in the EXT position, starting and stopping thepump is controlled by an external contact closure between pins 6 and 7 (Jumper B) (pins 4 and 8 for NEMA 4X models), and the pump speed isdetermined by an externally supplied 0–10V or 4–20 mA source.
