ATS48 Soft Start Troubleshooting and Introduction

The Altistart 48(ATS48) series of soft starters by Square D allows for consistent start/stop rates that are independent of motor loads. These devices are more advanced than the standard drives that cannot control the applied motor torque. Featuring contact wiring and control, the soft starter allows for near-seamless integration with existing operations. Many preset parameters are included with the device and they cover a large spectrum of operations. Additional parameters may also be loaded up to meet specific needs. Available power ratings include:

  • 3 – 200 HP @ 208VAC, 60 Hz
  • 5 – 250 HP @ 230VAC, 60 Hz
  • 10 – 500 HP @ 460VAC, 60 Hz
  • 15 – 600 HP @ 575VAC, 60Hz

The ATS48 series features a dual configuration of two motors which allows for a cascaded start/stop in many operations. Using the Torque Control System(TCS) the unit can minimize wear on gears which allows for less time servicing the unit.

The Altistart 48 series takes advantage of the PowerSuite™ software for programming of your drive or soft starter.  With this software, you will be able to monitor and document all of your operations. Configurations are easily saved via hard disk, CD-ROM, flash memory, etc. Using Ethernet technology, the user is able to configure and monitor operations on the go, and a constant feed of information allows for real-time opportunity to modify and adjust configuration files on the fly.

Troubleshooting can be an issue for people when so many different things are going on. It just isn’t feasible to stop operations every time an error occurs. Below is a list of fault codes for the ATS48 Soft Start series that will help determine most issues:
