Hi All, trying to sort out a motor control problem on my BG4000,
and on page 3-19 the last line is “You will see from this circuit that if the base of”…..
BUT – page 3-20 starts with: “and 1TR32 will be biased in the forward direction, so that control current…….”
Can anyone enlighten me as to the missing line/s ??
Thanks in advance..
Graham H.Read on through section 3.21….this gives a full description of the three functions associated with the drive for the transport system, you should be able to test the voltage levels at the associated transistor points when the control panel switches are operated, the notes are a little truncated and “solder ron” may be able to fill in the missing information as they where kindly donated by him.
