    Why is the screen blank on my NAiS GT Monitor?
    • T
      Timothy ChambersAug 20, 2025
      The screen might be blank on your NAiS Monitor because either the power is off, or, if only lamp and message parts are configured to the base screen, the value of the substitute reference device does not exist in substitute data. To resolve this, ensure the unit is properly powered according to specifications. Also, verify the address of the substitute reference device and the device values on the PLC side.

    How to fix a dim screen on NAiS Monitor?
    • D
      Diane BridgesAug 22, 2025
      A dim screen on your NAiS Monitor can be due to several reasons: the power voltage may be low, the contrast is set too low, or the backlight is off. Here's what you can do: 1. Check the capacity of the power supply unit to ensure it meets the monitor's power consumption needs. 2. Adjust the contrast via the system menu. 3. If the backlight is off due to the [Backlight Auto-off] setting, touching any area of the screen should light it up (unless a switch part is set on the touched area). You can change the backlight auto-off settings to prevent this.

      If the touch panel on your NAiS Monitor isn't working, it might be because valid conditions have been set for the switch part, but those conditions haven't been met. Check that the device status conditions on the PLC side are valid.

    Why doesn't the screen switch on my NAiS GT Monitor?
    • T
      Timothy RobinsonAug 27, 2025
      The screen on your NAiS Monitor may not be switching because no screen number has been written to the screen setting area from the PLC, or the screen number to which you are attempting to switch has already been written from the PLC to the screen setting area. Ensure that you specify the correct screen number.

    Why does an unspecified screen appear or why is there trouble when switching screens on my NAiS GT Monitor?
    • D
      Diane GoldenAug 28, 2025
      An unspecified screen appearing or trouble when switching screens on your NAiS Monitor can occur if the screen specification in the PLC screen setting, the GT main unit switch part, or the auto-paging is wrong; if the startup screen is specified in the GT configuration settings; or if an erroneous device or value is specified in the first word of the basic communication area word device. Specify the correct screen number. Check the start-up screen setting for the GT configuration settings in GTWIN. Delete unnecessary settings and re-transfer configuration data. Check the device content specified on the PLC side in the first word of the basic communication area. Do not use the basic communication area with ladder programs.

    How to troubleshoot data transfer issues from GTWIN to my NAiS GT?
    • H
      Hannah KimAug 30, 2025
      If you cannot transfer data from GTWIN to your NAiS Monitor, it could be due to the screen transfer cable not being connected properly, or the PC and GT main unit COM port are not correctly connected. Ensure that the screen transfer cable is correctly and firmly connected. Connect to the TOOL port with the screen transfer cable.

    How do I stop the backlight on my NAiS GT Monitor from going off too quickly?
    • T
      Timothy RiveraSep 1, 2025
      If the backlight on your NAiS Monitor goes off too quickly, the backlight auto-off timer setting may be too short. To fix this, change the backlight auto-off timer setting.

    What does it mean when my NAiS Monitor displays [Memory is Full]?
    • N
      Natalie BallSep 3, 2025
      The [Memory is Full] message on your NAiS Monitor indicates that the total capacity of transferred base screen data exceeds the monitor's capacity (384 kbyte capacity of the GT01, or 1.375 Mbytes for the GT11). Delete part of the base screen data so that the total capacity doesn’t exceed the limit. Data capacity can be checked by going to [View (V)]?[Memory Usage Conditions] on GTWIN menu bar. When the data capacity is not over the limit, invalid data could possibly be remaining in the GT main unit. When transferring data, do so after deleting the screen.

    Why are there no operating sounds when I press the touch panel on my NAiS GT Monitor?
    • T
      Tabitha JohnsonSep 5, 2025
      If you're not hearing operating sounds when pressing the touch panel on your NAiS Monitor, it could be because the [Switch Sounds] setting under [Options] in the switch part attributes is set to [Disabled], or the [Touch Sounds] setting under [Setup] in the GT configuration settings in GTWIN is set to [Disabled]. To resolve this, change the setting to [Enabled] in either or both of these locations.

    Why is the date/time display incorrect on my NAiS GT Monitor?
    • J
      Jacob WoodsSep 7, 2025
      If the date/time display is incorrect on your NAiS Monitor, it is likely that the PLC’s internal calendar timer used as a reference is incorrect. To correct this, adjust by rewriting the value in the PLC’s internal calendar timer.
