Tunnel Error
The controller will error if it can not open the inlet curtain, or if you are using a main curtain
it will error if it can not close the main curtain.
Note: If not using a main curtain, you must put a jumper wire across the
main curtain closed signal inside the control box.
If you see a tunnel error, check the following:
• Make sure that the inlet is operating correctly.
• If applicable, make sure the main curtain is operating correctly.
• Make sure that the curtain closed signals inside the control box are wired to the
auxiliary switches inside the PowerTrak.
Variable Speed Fans not Operating
If the variable speed fans are not operating properly, do the following:
• Try a different motor curve (P11).
• If the system is using 110 VAC, make sure that the neutral wire is connected to L1, and
the Hot wire is Connected to L2
• Make sure a proper earth ground is connected to the controller.
