Issue: Is it possible to run an ATS22 with a smaller motor or without a motor attached? Product Line: Altistart ATS22 Environment: All models in series Cause: Need for testing starter with minimal or no load attached. Resolution: No, SSt is a feature of the ATS48 soft start. It is not available on the ATS22. It has to have a load at the output. The following video is a tutorial for understanding the Small-Load or No-Motor limitations of Altistart 22:

Issue: The product selector will not allow selection of MOD C07. Product Line: Enclosed 22 Soft Start Environment: Enclosed 22 Soft Starts with Power Circuit B05 or S05 Cause: Attempting to combine Power Circuits B05 or S05 with Pilot Light Cluster C07. Resolution: Shunt Trip Power Circuits B05 ( Basic Shunt Trip ) and S05 ( Full-featured Shunt trip ) are not compatible with Pilot Cluster C07. The Fault indicator pilot on C07 is controlled by the ATS22 trip status relay output. When...

Issue: Troubleshooting StF Fault on Altistart 22 Product Line: ATS22 Soft Starter Environment: All models Cause: The StF fault means the starter has exceeded the maximum start time setting, tLS, in the SEt menu. Resolution: tLS needs to be set higher then the ACC time. For example: If ACC ramp up time is 10 seconds, then set the tLS max starting time to 20 seconds. If ILt current limit is too low, the motor may not reach full speed within tLS limit. Mechanical problems on the ...

The Altistart 22 soft starter is compliant with pollution Degree 2 as defined in NEMA ICS1-1 or IEC 60664-1.
For environment pollution degree 3, install the Altistart 22 soft starter inside a cabinet type 12 or IP54.
DANGER |
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH ATS22 soft starters are open devices and must be mounted in a suitable enclosure. Failure to follow these instructions will result in death or serious injury. |
Leave sufficient free space to help the air required for cooling purposes to circulate from the bottom to the top of the unit.
To avoid the soft starter to overheat, respect the following recommendations:
Mount the Altistart 22 Soft Starter within ± 10° of vertical.
Do not locate the Altistart 22 Soft Starter near heat radiating elements.
Electrical current through the Altistart 22 Soft Starter will result in heat losses that must be dissipated into the ambient air immediately surrounding the soft starter. To help prevent a thermal fault, provide sufficient enclosure cooling and/or ventilation to limit the ambient temperature around the soft starter.
If several soft starters are installed in a control panel, arrange them in a row. Do not stack soft starters. Heat generated from the bottom soft starter can adversely affect the ambient temperature around the top soft starter.
To help proper air circulation in the soft starter, grilles and forced ventilation can be installed.

ATS22 soft starters connected to motors with the delta connections can be inserted in series in the motor windings.
The following wiring requieres particular attention. It is documented in the Altistart 22 Soft start - soft stop unit user manual. Please contact Schneider Electric commercial organisation for further informations.
A 400 V - 110 kW motor with a line current of 195 A (nominal current for the delta connection). The current in each winding is equal to 195/1.5 or 130 A. The rating is determined by selecting the soft starter with a permanent nominal current (ICL) just above this current.
