How many starts per hour will the S811+ allow?

The S811+ will not limited the number of starts per hour. The limiting factor for considering the number of starts will be the motor's duty cycle. Long ramps times may limit the number of starts you can perform due to the heat generated on the SCR's. The Soft starter will fault on overtemp once 100 C  is reached and will need to be cool down before attempting another start. Excessive starts may also increase your thermal pile and result in overload trips.

You can monitor the overtemp values and thermal memory % in the monitoring menu using the Digital interface module(DIM).
