SED2 Conventional Bypass Option Operating Instructions Conventional Bypass Option Overview General Description During normal operation in a typical application, the input and output contactors close and the SED2 operates the motor (Figure 1). The bypass contactor provides the ability to operate the motor on utility power and eliminate the VFD from the motor control circuit. VFD0008R1 Input Device Input Device Drive Drive Motor Motor 2 Contactor Bypass 3 Contactor Bypass Figure 1.
PAGE 13
Operation Overview Operation Overview • • • • Drive Mode − Drive output contactor closes (and drive input contactor if supplied). The motor is controlled by the SED2 output. − Change the position of the "Drive-Off-Bypass" switch to OFF and the Bypass stops the SED2 by opening digital input 4, stop 3. Local Bypass Operation − Requires a jumper between bypass control terminals 7 and 8. Jumper is supplied from the factory. − The system goes to Bypass by closing the bypass contactor.

SED2 Conventional Bypass Option Operating Instructions Operation Overview, continued a. Safety Input • 6 − Requires a jumper between bypass control terminals 3 and 4. Jumper is supplied from the factory. − Contact must be closed for the motor to be run in either the Drive or Bypass modes. WARNING: This contact disconnects the 120 Vac control power circuit. Essential Service Mode − Closing between terminals 13 and 16 forces the bypass contactor to close regardless of the selected operation.

SED2 Conventional Bypass Option Operating Instructions Check Step ( ) 12. Record any other connections to the drive by terminal number to determine if special programming is required. ( ) 13. If applicable, verify that the building automation system logic is ready to perform adequately for start, stop, and speed command functions. This concludes the preparation process for SED2 startup.
PAGE 31
Start Up Procedures ( ) 9. To start the Drive, press and then (green start key). The drive will ramp up to “10 HZ” (or minimum speed). Verify that the direction of motor rotation is correct. NOTE: If the direction of motor rotation is wrong, turn the Drive-Off-Bypass switch to OFF; and turn Power Off! Wait for five minutes. Swap wires on the motor terminals (T1(u), T2(v)) or on the output terminals of the motor overload relay.
PAGE 32
SED2 Conventional Bypass Option Operating Instructions Check ( Step ) 17. Verify that running at full speed will NOT damage the system. Run the motor in bypass by turning the Drive-Off-Bypass switch to BYPASS. Record all the phase voltages and currents at this time to ensure that they are balanced and within ratings. ( ) 18. Turn the Drive-Off-Bypass switch to DRIVE and set panel to auto start/stop. Check speed references from application specific devices for appropriate operation.
