Power management
The HMI device is equipped with a power management function. If you do not operate the
HMI device within a configured time period, power management will switch the HMI device to
power saving mode. This extends the operating period of the HMI device until the next time
the main rechargeable battery is replaced or the next time it is charged.
Operating modes in power management
Power management has two operating modes:
● "Power Save 1"
– Reduces the brightness of the touch screen.
– The EMERGENCY STOP button remains available.
– As long as the HMI device is logged on, the enabling button remains enabled.
● "Power Save 2"
– The touch screen is switched off.
– Other power save measures are activated.
– The EMERGENCY STOP button remains available.
– The rotary switch remains available.
● "Power Save 1" corresponds to the "Reduce brightness" setting.
● "Power Save 2" corresponds to the "Switch off screen" setting.
Note
When the HMI device is logged on to a machine, "Power Save 2" operating mode is not
available.

Note
When you place the HMI device in the docking station, it will automatically assume the
operating state "Power Save 1" after 2 minutes.
If a time period of less than 2 minutes has been specified for activation of
"Power Save 1" mode in the WinCC flexible project, then this time period will be
applied.
The online help for WinCC flexible describes how to configure power management.
