123.What is balance-less transfer and how to achieve it?

This is experienced in a controller which is controlling more than one secondary output simultaneously. If one of the secondary o/ps is switched to manual or fails, the remaining o/ps have to be adjusted(balanced) automatically to attain the desired parameters. This action of automatic balancing of the active o/ps (in a multi o/p controller) without experiencing a bump is known as Balance-less transfer (achieved thru slow ramping). The combination of Auto Gain change and Tracking techniques are used to achieve the same.
