Auto Bypass without Interlock
Description
The Auto Bypass feature enables the SED2 to initiate automatic bypass mode operation.
Closing of the SED2 Relay sends the motor to hand bypass mode. See the SED2 VFD
Startup, Operation, and Maintenance Manual (125-3201) for programming of this relay and
for its desired action.
When the SED2 initiates bypass mode operation, the following occurs:
The SED2 stops delivering power •
•
•
The output contactor opens.
The bypass contactor closes and the Programmable Output on the Controller board
closes.
NOTES:
1. All safety conditions must be met for bypass mode operation.
2. The input contactor remains energized.
