5. DIP SWITCH
5.1 DIP SWITCH POSITIONING
There are sixteen DIP switches on the control board.
Generally the position of the DIP switches is set during the unit construction phase and therefore it is not necessary
to change the assigned positions.
If it is necessary to change the position of one or more DIP switches, it is imperative to disconnect the power supply
to the electronic board before proceeding with the modification.
The following table shows the meaning of the DIP switches.
