Figure 1.77 Transfer to Bypass and Safety Circuit
Emergency Override
When the Emergency Override (Smoke Purge) digital input is closed, the drive will perform the transfer. Refer to Immediate
Transfer to Bypass on page 144 for details.
If programmed, the BP BAS Interlock Relay Contact will close before the transfer occurs. During the transfer process, and if
BAS Interlocks are present, the BAS Interlock Input MFDI must be closed before the drive will close the bypass contactor to
run the motor on line voltage.
When the Emergency Override MFDI is closed, the state of BP Drive/Bypass Select MFDI, Run command, Bypass Run
command and BP Customer Safeties MFDI have no impact on the operation of the system. When Emergency Override opens,
the drive operates based on the other digital input commands. If the drive is commanded to run, the drive will perform the
switch. Refer to Transfer to Drive Operation on page 144 for details.
