Do to the short work week, we have a short post. I hope everyone has an enjoyable and laughter filled Thanksgiving holiday.
If you have one of the new MMI8000X Series or are contemplating purchasing one, there is a power button on the front of the unit. The power button also has an LED incorporated into it that lights when the HMI is running.
In order to avoid confusion here is how it is supposed to work:
Once the unit is powered up, the button can be pressed and held for about 5 seconds to make the unit power down. (commonly referred to as a "soft power down")
Once powered down, if power is still connected, the unit can be powered up again by pressing the power button. This allows the unit to be powered down without having to power down the entire panel or mounting a separate power switch just for the HMI.
If the unit is powered down and power to the unit is cycled, the unit does power up. So, if you desire, you can still restart the unit by cycling power to it.
Summary:
Units affected: MMI8150X, MMI8121X, MMI8104XH
Power applied to HMI always starts the HMI.
When power is maintained to the HMI, the power button can be used to power OFF and power ON the HMI. (Just like the power button on your appliances at home.)
