Overview

The Pump Application Module expands the soft starter's input and output functionality and is ideal for applications where greater control
and feedback are required. The module provides three digital inputs and one PT100 sensing input, which can monitor system conditions
and shut the motor down safely if an unwanted condition occurs.
The Pump Application Module is easy to install and configure, and no special tools or additional software are required. The module is
powered through the soft starter's serial port.
The Pump Application Module has been designed for pumping applications but can be easily adapted to any situation requiring
input/output expansion.

Inputs

The Pump Application Module has three digital inputs which can be directly connected to external inputs such as pressure switches,
flow switches, limit switches or PLC outputs, and one PT100 input which can be directly connected to a temperature sensor. When an
input activates, the module will trip the soft starter. To resume normal operation, the soft starter must be reset.
Each input is designed for a specific function.
