Load voltage decay operation (open transition)

Load voltage decay utilizes the load voltage measurements to sense

back EMF that is generated when the transfer switch is in the

neutral position (electrical load disconnected). It provides a delay

in transfer in either direction if an unacceptable level is sensed

as established by a customer programmed level. The transfer will

not take place until the back EMF decays below the acceptable

programmed level. This feature has a separate setting of enabling or

disabling the operation. If disabled, the transfer switch will not delay

in the neutral position and will transfer between the sources as fast

as possible.
