WARNING: When using the 65-2320RK-100, you must follow the instructions and warnings in this manual to assure proper and safe operation of the 65-2320RK-100 and to minimize the risk of personal injury. Be sure to maintain and periodically calibrate the 65-2320RK-100 as described in this manual. -
Page 6: Description
NPT mounting threads at the top of the detector allow you to mount the detector to the junction box or a 3/4’’ NPT conduit fitting. Two color-coded leads extend from the top of the detector. The leads allow you to connect the detector to a controller. 2 • 65-2320RK-100 Oxygen Transmitter 1.888.610.7664 www.calcert.com... -

Page 9: Wiring The Oxygen Transmitter To A Controller
The power cable may disrupt the transmission of the transmitter signal to the controller. 11. Connect the wires to the applicable detector/transmitter terminal strip at the controller as shown in Figure 3. 65-2320RK-100 Oxygen Transmitter • 5 1.888.610.7664 www.calcert.com sales@calcert.com... - Page 10 12. If shielded cable is used, connect the cable’s drain wire to an available chassis (earth) ground at the controller. RKI controllers typically have a ground stud that can be used to ground the cable’s drain wire. 6 • 65-2320RK-100 Oxygen Transmitter 1.888.610.7664 www.calcert.com...

Page 11: Startup
The procedure below describes applying zero emission air, usually called zero air, using a calibration kit that includes a calibration cup, calibration gas, sample tubing, and a fixed flow regulator with an on/off knob. RKI Instruments, Inc. recommends using a 0.5 LPM (liters per minute) fixed flow regulator. -
