SP ERR or ERR Message 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.
