Connecting The Handle Switch - Bennett 3000 Series Service Manual

531 Commercial / Industrial Electronics
Connecting the Handle Switches -
The handle switch cable is a black/red 2 wire cable that connects the
handle to the barrier board. The cable comes from the barrier board,
passes through the same potted conduit as the ribbon cable for the
pulsers (see Figure 1) and connects to the handle switch board.
The general rule is that the red wire go to the "odd" numbered terminal
and the black wires go to the "even" numbered terminal. There are 4
terminals on this board marked T1-T4. If you look at the board with the
"Reed" switch facing down, then the bottom right terminal is T1 and T2
is above that. The top left is T4 is T3 and below that.
Jumper JP2 is at the top and MUST HAVE A JUMPER or else this
circuit will not work.
Original Style Handle Board
Jumpers on JP1 are not

Reed Switch
Current production style board -
The current board uses barrel style connectors rather than shunt
jumpers and a solid state magnetic switch rather than a glass style.
Both the original and the current board functions the same and the
part numbers remain the same.
