12.2 Error Codes
12.2.1 Descriptions
If your controller is displaying an “E1”, or “E2”, etc. the controller has recorded an
error. The controller records errors from sensor readings, and tunnel related
problems. To diagnose your controller problem, look up the error on the table
(under “Error Codes”) and look across the table to find the components that have
failed. ( Items with an “x” have failed according to the controller.)

12.2.2 Possible Solutions
Sensor Error
If any of the sensors are bad try the following:
• Reset the controller by taking power away at the breaker, or
unplugging it.
• Determine which sensor is bad, then check the connection inside the
controller door.
• Determine which sensor is bad, then check the sensor that is hanging
in the house to make sure that it has not been damaged.
• Check the wire going to the sensor(s) to be sure there are no staples
through the wires.
• Replace the bad sensor.
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.
