E-Bypass Control Features

Auto Bypass

• Relay logic allows user to send the motor to bypass

mode based on the drive’s programmable relay.

• The drive’s programmable relay, typically set to fault,

can be set up for applications that run full speed for

an extended period of time.

Enable Input

• Generally used for safety tie-ins; the motor will not

operate the drive or bypass when open.

Common Remote Start/Stop

• Common remote start/stop can be used in both drive

and bypass mode.

Essential Services Mode

• Also used for smoke purge; the motor goes to bypass

regardless of the selected mode.

• No call to stop will have an effect, including open

safety or stop commands.

• Only turning the power off or opening this contact will

stop the motor.
