Thermal fuse, power supply unit monitoring

The integrated power supply unit is equipped with a thermal

fuse. If there is an overload this will switch off the power supply.

After the fuse cools off, it will switch the power on again.

There is a green LED on the power supply unit. This flashes

when there is an error in the power supply unit.

Thermal fuse, battery monitoring

There is a thermal fuse on the motherboard that monitors the

battery current and protects against reverse polarity.

When the fuse cools off, the battery current is switched on

again.

Updating the panel software (firmware) via USB

You can update the panel software using the USB port on the

lower left side of the main board. To do this, connect the USB

port to your computer and install the programming software

supplied on the CD. Follow the on-screen instructions.
