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-04 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. RKI controllers typically have a ground stud that can be used to ground the cable’s drain wire. 35-3010RK-04 Sample-Draw Detector • 9... - Page 14 Sample Draw Housing Main Circuit Board Interconnect Terminal Strip 24 VDC - Controller LEL (Controller Transmitter S (4/20 mA) Terminals Terminals) 24 VDC + Figure 5: External (Field) Wiring, Sample Draw Detector 10 • 35-3010RK-04 Sample-Draw Detector...
