The Altistart 48(ATS48) series of soft starters by Square D and Schneider Electric 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:
| Fault Code | Description |
|---|---|
| nLP rdY | Soft start without run command and: • Line power not supplied • Line power supplied |
| tbS | Starting time delay not elapsed |
| HEA | Motor preheating in progress |
| (Use SUP menu to set up monitoring parameter. Factory setting: Motor Current.) | Soft start with run command |
| brL | Soft start braking |
| Stb | Waiting for a command (RUN or STOP) in cascade mode |
| CFF | Invalid configuration on power-up |
| CFI | Invalid configuration |
| CLF | Loss of Control Power |
| EEF | Internal memory fault |
| EtF | External fault |
| ErF | Line frequency out of tolerance |
| InF | Internal fault |
| LrF | Locked rotor fault |
| OCF | Overcurrent fault |
| OHF | Soft start overheating fault |
| OLC | Current overload fault |
| OLF | Motor overload/ground fault |
| OtF | Motor thermal fault detected by PTC probes |
| PHF | Loss of line or motor phase |
| PIF | Phase reversal fault |
| SLF | Serial link fault |
| StF | Excessive starting time |
| ULF | Motor underload fault |
| USF | Lack of AC line power on a run command |

THANKS
WE APPRECIATE YOUR HELP
IF CAN EXPLAINED IN SPANISH IS BETTER
our soft starter just try to start and immediately stops without by passing and does not show any fault on screen but goes back to being ready..4 motors where burnt ..because the starter did not protect ATS4D75Q
ALTISTART 48
230V-415V _50/60Hz-75A
Please assist with error code SSCR on Altisstart 48
Regards
Deon
my soft start altstart48 was given PHF messege and we found some scr fult and we were replaced but the fualt appearing until it. can you help me
Did you fix this issue, I’ve got the same?
3oohp motor shuts down intermittently through out day,starts right back up with push of start button,there are no codes shown….replaced start/stop button and went thru control ckt. found no issues.. possibly be faulty board in soft start?
Altistart 48 remote keypad has err 7 code. Soft start has RDY on display. Will not start from HMI controls. Unplug keypad from mod bus port expander, soft start displays nST and will start from HMI. Swapped keypad with a know good one and err/fault stays with the unit not the keypad. Tried disconnecting all comm devices and reconnecting all, flashed nST a couple times then back to err7. Any clues I can chase?
Hi
We have Altstart 48 on the plant. We have done all the necessary settings and tested the unit in test mode with the motor disconnected. We set the acceleration time to 8 sec and the deceleration time to 8 sec. When the second contactor licks out after deceleration we still measure 440v on the out going of the soft starter to the motor. Please advise is this correct or if there is another setting that must be programmed. The motor is a 440v x 240kw motor. Please can you advise asap.

The City of Virginia Beach, VA has a Telemecanique 48, trouble code nLP, which may mean “No Line Power”. Do you know if any companies repairs and certifies this motor starter/vfd?
Dear All, Altistart 48 soft starter is not giving out voltage properly like receiving 189 instead of 400V and R2 relays is not activated to energize the by pass contactor. So we are getting high current with low voltage output in our soft starter. So please share your experiences
we have altistart48 on the plant, it does not display RDY when the 3phase power is switched on, kindly assist with what could be the problem. Thank you.
Potter Well field Amarillo Texas, we have 21 Well using the Altstart 48, and this is the first time with a code I can’t find. The code is (—), can you identify what is wrong so we can get Well back online. Thanks.
