6 • 35-3010RK-04 Sample-Draw Detector
sensor signal cable carries no signal in this version of the 35-3010RK.
Main Circuit Board
Figure 3: 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 3).
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 a controller.
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 sensor/transmitter terminal strip to connect sensors or
transmitters to the main circuit board.
NOTE:
The sensors are factory wired to the sensor/transmitter terminal strip. See
“Wiring the Sample Draw Detector” on page 9 for all wiring procedures related
to the sample draw detector.
