Supply Fan VFD Bypass
Supply Fan VFD Bypass (if configured) allows fan operation when the VFD is not available (Supply
Fan Bypass mode operation is available whether a VFD is functional or not). This is accomplished
by interacting with the Supply Fan Bypass Mode Enabled button on the TD7 Display located under
Settings – Unit Settings – Service Settings screen. Refer to Figure 36, p. 52. Whenever this
bypass opti
on is installed, the unit will include all of the necessary components and wiring to
bypass the VFD assembly(s) and allow the supply fan(s) to operate in full airflow modes. Supply
fan airflow proving/un-proving is important to insure the inertia of the fan has reduced enough to
avoid potential fan direction reversal due to component miss-wiring. Please see the Intellipak™
IOM for details concerning airflow proving.
