Page 5: Overview
WARNING: When using the 35-3010RK-07, you must follow the instructions and warnings in this manual to assure proper and safe operation of the 35-3010RK-07 and to minimize the risk of personal injury. Be sure to maintain and periodically calibrate the 35-3010RK-07 as described in this manual. -
Page 6: Description
Use the two conduit hubs on the bottom of the housing to make wiring connections. An aluminum subpanel is mounted to the interior of the housing. The sample draw detector’s internal components are mounted to the subpanel. 2 • 35-3010RK-07 Sample-Draw Detector... -

It prevents water and other liquids from contaminating the flow system. Replace the filter when it appears dirty, discolored, or clogged. If a liquid other than water is drawn into the filter, replace the filter as soon as possible. 35-3010RK-07 Sample-Draw Detector • 3... - Page 8 If the flow rate falls below the preset low flow level, the pressure switch causes the fail relay to interrupt the signal to the controller for all three channels. This causes a downscale reading at the monitor on these channels. The low flow level is factory-set at 0.6 SCFH (±0.2 SCFH). 4 • 35-3010RK-07 Sample-Draw Detector...

CO sensor signal and the one of the right is for the H S sensor signal. Since the CO sensor is replaced with a dummy plug in the 35-3010RK-07 the CO sensor signal cable carries no signal in this version of the 35-3010RK. - Page 10 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. 6 • 35-3010RK-07 Sample-Draw Detector...
- Page 11 Amp 2 is on the right and is for the H S channel. Since there is no CO channel in the 35-3010RK-07, Amp 1 is not used. The zero and span pots are used during calibration. Use the span pot to make adjustments to gas response readings and the zero pot to make adjustments to the zero reading.

Page 12: Installation
Slightly loosen the screw that secures one of the mounting feet to the housing, then rotate the mounting foot 180 degrees (see Figure 4). Tighten the screw that secures the mounting foot to the housing. Repeat steps 3 and 4 for the remaining three mounting feet. 8 • 35-3010RK-07 Sample-Draw Detector... -
Page 13: Connecting The Sample Lines To The Sample-Draw Detector
Route the cable or wires in conduit leading from the sample draw detector to the controller. Connect the drain wire to an available chassis ground at the controller end. RKI controllers typically have a ground stud that can be used to ground the cable’s drain wire. 35-3010RK-07 Sample-Draw Detector • 9... - Page 14 Interconnect T erm inal Strip Controller LEL Terminals 24 VDC - S (4/20 m A) (Controller Transmitter Terminals) 24 VDC + Controller Oxygen + (W ) Terminals Figure 5: External (Field) Wiring, Sample Draw Detector 10 • 35-3010RK-07 Sample-Draw Detector...

Verify a reading of 0% LEL for the IR CH channel at the controller. If the display reading is 0% LEL, the combustible detector is in normal operation. If the display reading is not 0% LEL, perform a zeroing operation at the controller. See 12 • 35-3010RK-07 Sample-Draw Detector... -

Verify a reading of 0%LEL for the IR CH channel, 20.9% for the oxygen channel, and 0 ppm for the H S channel (100 mV at the amp 2 test points). Investigate significant changes in the reading. 35-3010RK-07 Sample-Draw Detector • 13... -

Place the new hydrophobic filter back into the metal clamp. Replacing the Charcoal Filter NOTE: The charcoal filter does not normally need to be replaced in the 35-3010RK-07 because it does not include a CO sensor. Turn off or unplug power to the controller. -
Page 22: Calibration Frequency
For example, with a calibrating sample of 25 ppm H S and a fullscale setting of 100 ppm H S, the correct output for the H S test points is 200 mV. 200 (mV) = (25/100) X 400 +100 18 • 35-3010RK-07 Sample-Draw Detector... -
