5.4 VFD Setup
VFD setup is identical to a Type 2 system – see section 4.4.
5.5 Operation
Operation is essentially identical to a Type 2 system (see section 4.5), except that in AUTO mode the
start/stop interlocks are now integral to the system and not optional. Note that ramp-up and ramp-
down times remain.
To avoid overheating the motor due to lack of airflow, the fan should never be operated in MANUAL
mode unless at least one damper is open.
5.6 Troubleshooting
Troubleshooting is essentially identical to a Type 2 system (see section 4.6), with the addition of possible
problems with damper wiring or a damper switch. These may be checked separately by disconnecting
the damper control panel connections and verifying that the switch contact closure is sensed properly.
The damper light should also illuminate.
