internal super capacitor has still power, the internal application starts again and can
control the outputs (therefore BSP LED green).
Firmware of POL98X.00/XXX features different diagnostic functions such as
disconnection detection, under voltage detection or shorted coil. The function
"disconnection detection" is active only during valve / motor positioning, not during
hold on.
DIP switch is equipped with the extension module to communicate with the
controller. Switch 1, 2, 3, 4, and 5 are configurable to set the slave address, while
switch 6 acts as peripheral bus termination. When extension module works as the
termination in the network, switch 6 needs to be set as ON.
The order of bits for the switch is from 5 to 1, 5 is the lowest bit, while 1 is the
highest bit. The following table shows the logic of slave address:

By combining switches 1, 2, 3, 4 or 5, maximum 31 slave addresses can be
configured. The configuration formula is as below: 2
