Installing or Deactivating the Damper/BAS Interlock Circuit
One of these three actions below must be taken prior to equipment start-up to prevent the Damper/BAS Interlock
condition.
1. Option 1: Install a normally closed (N.C.) BAS Interlock Circuit between TB1-3 and TB1-9 on PCB A2.
Refer to Figure 6 .
2. Option 2: Install a jumper between TB1-3 and TB1-9 on PCB A2 according to Figure 7 . This method should be
used if a BAS Interlock Circuit will be added later in the installation.
3. Option 3: De-activate terminal TB1-3 by moving DIP switch S2-8 to the ON position (toward the enclosure door).
Refer to Figure 8 . This solution is only suggested if a BAS Interlock Circuit will never be applied to the drive system .
