  1. Pump Application Interface

  2. Overview • Increases the functionality of the soft starter for pumping applications - four additional trip inputs. • Eliminates the need for external relays, timers, mini-PLCs, etc. • Provides a simple, cost effective solution for pump control systems

  3. Functionality • Low Pressure input (0–20 min enable delay, 0–60 sec trip delay) • High Pressure input (0 – 60 sec trip delay) • Low Water Level input (0 – 60 sec trip delay) • PT100 input (selectable trip temperature, Off – 250ºC) • N/O or N/C input selection • Common trip relay output • Powered and reset from the soft starter

  4. Physical layout • 5 x rotary switches (configure trip delays and trip levels) • 1 x 3-way DIP switch (configure digital input logic) • 4 x status LEDs (indicate state of each input) Low pressure High pressure Low water level PT100

  5. Terminal layout • 13 way removable terminal block • 1.5mm2 maximum cable capacity • 30 metre maximum cable run for digital inputs using unshielded cable • 150 metre maximum cable run for PT100 input using twisted pair/shielded cable

  6. Electrical layout Remote input connections are still required to control the soft starter

  7. Low pressure input (A) • Input is only monitored in Run mode after the Enable Delay has elapsed • Trip action occurs if the input is activatedfor the Trip Delay period • Coast to stop after trip • Select for N/O or N/C input

  8. High pressure input (B) • Input is only monitored in Run mode • Trip action occurs if the input is activatedfor the Trip Delay period • Coast to stop after trip • Select for N/O or N/C input

  9. Low water level input (C) • Input is monitored in all modes • Trip action occurs if the input is activatedfor the Trip Delay period • Coast to stop after trip • Select for N/O or N/C input

  10. PT100 input • Input is monitored in all modes (@ 40ºC-250ºC setting) • Input is disabled when set to Off • Trips if the monitored temperatureis reached for more than 2 seconds • Coast to stop after trip • Trips on open or short circuit input

  11. PT100 input

  12. Trip relay output • Output activates on trip (interface or soft starter) • Single pole-changeover • 2A @ 400 VAC inductive, 6A @ 30 VDC resistive

  13. Input configuration • High Pressure, Low Pressure and Low Water Level digital input logic is selected using DIP switches A, B, C • N/O: open = healthy input closed = trip • N/C: closed = healthy input open = trip
