sensor signal cable carries no signal in this version of the 35-3010RK.

Main Circuit Board

Figure 4: Main Circuit Board

The main circuit board includes the interconnect terminal strip, sensor/transmitter
terminal strip, amp 1 circuit, amp 2 circuit, pump terminal strip, relay, and reset switch
(see Figure 4).

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 bottom edge of
the main circuit board. Use the interconnect terminal strip to connect the sample-draw
detector to power and an external device.

Sensor/Transmitter Terminal Strip

The sensor/transmitter terminal strip is the sixteen-point terminal strip near the right
edge of the circuit board. Use the transmitter terminal strip to connect sensors or
transmitters to the main circuit board.
