Is it possible to run an ATS22 with a smaller motor or without a motor attached?
All models in series
Need for testing starter with minimal or no load attached.
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:
The product selector will not allow selection of MOD C07.
Enclosed 22 Soft Start
Enclosed 22 Soft Starts with Power Circuit B05 or S05
Attempting to combine Power Circuits B05 or S05 with Pilot Light Cluster C07.
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 a shunt trip power circuit is used, the ATS22 trip status relay controls the shunt trip and therefore is not available for pilot light control. In a fault condition, the shunt trip will interrupt power at the main disconnect and all indicator lights will be out.
Can the Altistart 22 monitor motor power?
All serial numbers for Altistart 22
No, there is no way for the softstart to monitor motor power unless an external option is added.
Is there an exchange program for the Altistart 22?
All serial numbers
No, Schneider do not offer an exchange program for the Altistart 22 Soft Starts.
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.
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 Â± 10Â° 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.
