When the UPS wants to move to bypass mode, this function determines whether the controller
will check the quality of the bypass voltage or not, before moving to bypass.
Select Forced if you want the UPS to move to bypass regardless of the quality of the bypass
voltage.
Select Controlled if you want the UPS to determine if the bypass voltage is acceptable before
transferring to bypass. In this case, if the bypass voltage is not acceptable, the UPS remains in
Inverter mode. The range of what is an acceptable bypass voltage can be set to wide or
narrow.
