Danger!
If a reset is carried out after a fault, the motor will start
immediately if a start signal is applied simultaneously. To
avoid the risk of serious or fatal injury to personnel, you
must ensure that the start signal is not present before
acknowledging an error message with a reset This
prevents the risk of damage and injury.
