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.
