Troubleshooting
2.1 When You Cannot Download Project Data
If you are unable to download project data from the WindO/I-NV4, press the top left corner of the panel for three
seconds or longer while at the same time turning the power off and back on again.
The screen in the System Mode is displayed, and then MICRO/I becomes downloadable status. If you download via
Ethernet, check again the setting of TCP/IP before executing the download.
Also, when MICRO/I does not show the System Mode screen and continues a blackout having a bleep each second,
be sure to download using Serial Interface 2 or port for USB.
2.2 If the backlight is OFF and the buzzer sounds
If you fail to download the runtime program to MICRO/I, the backlight may turn to OFF and a beep may sound
continuously every second, even after the power has been turned off and on again. Rectify the situation by
downloading the project using WindO/I-NV4 via USB cable.
2.3 Touch Panel Does Not Respond Correctly
If the touch panel needs to be readjusted, then go to the System Mode to readjust the touch panel. For details about
adjusting method, refer to Chapter 34 “Touch Panel Adjust (TP Adjust)” on page 34-9.
2.4 Power LED light is OFF
If the LED on the front of MICRO/I does not light up when power is turned ON, it may indicate a problem exists in the
main unit. Contact your vendor or IDEC Corporation.
