5.7. Powering up the DLoG MPC 6
Only power up the DLoG MPC 6 after connecting all of the devices.
The DLoG MPC 6 is powered up by connecting it to an appropriate power supply and
then, depending on the version of the device, either using the
power switch or the
ignition signal
Make sure there is a suitable disconnecting device such as a power
switch or circuit breaker in the power supply circuit.
5.8. Protecting the TFT display from the memory effect
The TFT display of the DLoG MPC 6 has to be protected from the burning in of a
motionless image. An image that has remained motionless for too long can cause
irreversible damage to the display. With TFT displays there no cathode rays burning in
an afterimage as in old TV sets or monitors, but TFT displays still have a “memory
effect”. This is because with a still image the liquid crystal molecules align themselves in
a certain way and become inert if they are not moved. Like burning in the effect is
irreversible, but can be avoided by regularly turning off the display or by using a
screensaver with changing content.
Define in the power management center of the utilized operating system that the
displays of the DLoG MPC 6 should be turned off when no user input occurs.
A motionless image can stay on the display for a maximum of 12 hours. After more than
12 hours there is the risk of the “memory effect”.
Important for the lifespan of the backlighting:
Choose a turn off time that is definitely not too short (not less than 30 min) since frequent
turning on of the backlighting will noticeably reduce its lifespan. This particularly applies
at low temperatures. Here the backlighting of the display should never be switched off
but instead a screensaver should be used which displays a changing or completely black
screen in order to achieve the maximum lifespan of the backlighting.
