Connecting The Handle Switch - Bennett 3000 Series Service Manual

210 Retail Electronics - Handle Switch
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 Style Handle Board - This newer style board utilizes barrel
connectors and a solid state type magnetic switch rather than the
original style board, which used a "shunt jumper" style and a glass
magnetic switch.
Both style boards operate identically and have the same part
number.
On the 3K series dispenser, the barrel connector jumper should be
set as shown.
