Connecting the Sample Lines to the Model 1017-03
1. Attach 1/4 inch O.D. rigid sample tubing to the INLET fitting.
CAUTION: If you use flexible sample tubing (vinyl or polyurethane for example), use an
appropriate metal insert to seal the connection between the tubing and the INLET
fitting. See the Parts List for an example of an appropriate metal insert.
2. Place the opposite end of the tubing at the sampling area.
CAUTION: Avoid loops or slumps in the incoming sample line. To reduce response time, keep the
incoming sample line as short as possible.
3. Install an appropriate line filter and flowmeter in a convenient location on the inlet
line. The 33-3050RK line filter with flow indicator is recommended for verifying there
is sufficient flow.
4. Install an appropriate valve before the flowmeter to allow adjustment of the sample
flow to 2.0 SCFH (a flowmeter with a built in valve may also be used).
5. Attach 1/4 inch O.D. rigid sample tubing to the EXHAUST fitting.
6. Route the opposite end of the tubing to an open area where the sample can safely
disperse.
Wiring the Model 1017-03
WARNING: Always verify that power is off before making or changing any wiring
connections.
1. Verify that all power is off.
2. Unscrew the cover from the housing.
3. Guide a six-conductor, shielded cable, or six wires in conduit through the conduit
opening on the right side of the housing. Use appropriate conduit fittings and
construction technique for the environmental rating and hazardous location
classification of the housing. The housing is rated NEMA 4 and classified explosion
proof for Class I, Groups B, C, and D.
4. Connect two wires to the input power terminal strips as shown in Figure 4.
5. Route the two wires back to the 24 VDC power source.
6. Connect the detector leads to the sensor terminal strip in the housing.
CAUTION: If shielded cable is used, leave the shield drain wire insulated and disconnected at the
detector. You will connect the opposite end of the cable’s drain wire at the controller.
7. Secure the cover to the housing.
8. Route the cable or wires leading from the Model 1017-03’s sensor terminal strip
through one of the conduit hubs at the controller housing. Use appropriate conduit
fittings and construction technique for the environmental rating of the controller. RKI
controllers are typically rated NEMA 4X.
