Section 7-3 Maintenance of the NT631/NT631C Error Details NAK received Displayed Probable Cause Remedy Check the settings for allocated words and bits. If noise is a possible factor, distance the cable from sources of noise and insert a noise filter in the power supply line. If using the equipment in a location subject to a lot of noise, use a cable with a high degree of protection against noise for the transmission route. Also make the cable as short as possible.
Section 7-3 Maintenance of the NT631/NT631C The life of the backlight varies, particularly in accordance with the temperature in the environment in which it is used. It should be replaced when it becomes dim and the screen becomes hard to read. The life expectancy of the backlight for the NT631C-ST152@-EV2/ST153@EV3 at high brightness is 50,000 hours. The backlight cannot be replaced by the user, however. Contact your OMRON service center when the backlight needs to be replaced.
Section 7-3 Maintenance of the NT631/NT631C Removing and Fitting The Touch Panel Cable Removing The Touch Panel Cable: Pull the arrow-marked sections up to the cable side to unlock the connector, and remove the cable.
