hard to be installed, we designed the Control board 3.
Contro l boa rd 3:
the current edition.
Now the part number of control PCB is 0010451971
2. Pow er board 0010451531
There are two types of power board, and they have the same dimensions, but have the different voltage
testing parts. That is easy to distinguish.
The newly power board adopts the voltage sensor to test the voltage. On the board there is a black square
type voltage sensor. The old board adopted the LM331 to test the voltage, which is an inserted part IC with
8 feet.
However both the new or old power boards can match any of the control board, but the CPU diagrams are
different.
3. Fil ter board 0010451536
Originally, the electric control box has not any filter board. In order to avoid the exterior interference and
result in the bad communication, the second edition (current edition) are all added the filter board.
instead of 0010451530.
The new control board(0010451971) also can be used as 0010451530,but the connector
"OH" must be shorted.
