Restoring Locked HMI
The HMI optionally included in the W2KIT and WattsOn-MCM features an "HMI Settings" menu. This menu has options including the initial start screen. If the HMI is not configured correctly, it is possible to "lock" the HMI in a non-standard screen, which will prevent the regular displays from showing.
eg: HMI locked on keyboard screen due to improper setting in HMI Settings menu.
To resolve this, follow these steps:
- Touch and HOLD the LOWER LEFT corner of the screen while power cycling the unit
- You will see a menu come up in Chinese, select “English” from the top
- Select “System Setting”
- Allow the HMI to boot into the settings menu, Select “English”
- Select the “Initial Window”
- Set "Initial Window to "0”>/li>
- Press “Restart” and allow the HMI to boot normally.
