Pump Application Interface

30 October 2006

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

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

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)

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

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

30 October 2006

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

30 October 2006

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

30 October 2006

PT100 input

• Input is monitored in all modes (@ 40ºC-250ºC setting)

• Input is disabled when set to Off• Trips if the monitored temperature

is reached for more than 2 seconds• Coast to stop after trip• Trips on open or short circuit input

Trip relay output

• Output activates on trip (interface or soft starter)

• Single pole-changeover• 2A @ 400 VAC inductive,

6A @ 30 VDC resistive

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
