Manual Transfer Scenarios
Manual transfer is prevented in specific scenarios. The following table indicates
when a manual transfer can or cannot be performed. Certain scenarios require
pressing the front panel Alarm Override button in addition to the Manual
Transfer button to perform a manual transfer. See
Alarm is Present (on page 114).
Make sure the front panel Manual Transfer button has been enabled before
using it. You can verify the button status via the Alarm indicator lamps. See
