CAUSE - Noise entering the controller through the “SmartPort” wiring or it is wired incorrectly.
SOLUTION - A few steps are necessary to determine cause of “Err” message.
1. Check SmartPort® Wiring
If the “Err” message is displayed without a device attached, check that SmartPort® wiring is correct. Make sure that the SmartPort wiring is not bundled with the field wiring. The white SmartPort® wire must be attached on the terminal next to the blue wire on the REM terminal, then red above ground. See illustration to the right.
2. Replace the SmartPort®
The SmartPort® connector may be damaged. Replace the SmartPort®.
3. Check Device (Remote Receiver)
If “Err” message occurs when device is plugged into the SmartPort® the device may have the wrong station count set or the device may be defective and should be replaced. Check the maximum station count setting on your hand-held remote.
