Figure 4: Main Circuit Board
The main circuit board includes th e interconnect terminal strip, sensor/transmitter
terminal strip, amp 1 circuit, amp 2 circuit, pump terminal strip, relay, and reset switch.
NOTE: The flowmeter and status lights are mounted to the main circuit board but are
considered part of the flow system.
Interconnect Terminal Strip
The interconnect terminal strip is the sixteen-point terminal strip near the bo ttom edge of
the main circuit board. Use the interco nn e ct termin al strip to connect the samp le-draw
detector to a controller.
Sensor/Transmitter Terminal Strip
The sensor/transmitter terminal strip is the sixteen-point terminal strip nea r the right
edge of the circuit board. Use the transmitter terminal strip to connect sensors or
transmitters to the m ai n circuit board.
