Appendix C — Interlock Damper Start Example
Interlock Damper Start Example Using PID Duct Static Control Signal
Figure 13: Interlock Damper Start with PID Duct Static Example
Step 1. Wire load line, digital I/O per example and verify
voltage and amperage
Step 2. Static check drive SCR, IGBT, DC Bus per Static Check,
Page 20 and 21
Step 3. Start-up wizard (Duct static application)
Step 4. Select hand to check motor rotation
Step 5. Press Start and to increase speed in Hand mode
Step 6. Select Remote to run in Auto
Step 7. Tune PID per diagram below
