Jumper selections
On the OPTBB board, there is one jumper block used to program the control voltage (auxiliary
voltage). The factory default and other available jumper selections are presented below.
NOTE! It is recommended to use a +12 or +15 supply voltage instead of 5 V.
This is because our interface does not support "sense" function to compensate voltage drop which
results in a cable length limit of about 60 m with 0.5 mm
2
wire section for the supply. The problem
does not exist with 12 or 15 v supply.
If 5V is used, it is recommended to use two or more wires in parallel for supply connection.
