7. Connect the detector leads to the detector terminal strip as shown in Table 4 and
Figure 3.
8. Reinstall the junction box cover.
9. Turn on or plug in incoming power to the controller.
10. Turn on the controller.
CAUTION: Allow the replacement detector to warm up for 5 minutes before you continue with
the next step.
11. Calibrate the replacement detector as described in the Calibration section of this
manual.
12. Secure the junction box cover to the junction box.
Calibration Frequency
Although there is no particular calibration frequency that is correct for all applications, a
calibration frequency of every 3 to 6 months is adequate for most CO transmitter
applications. Unless experience in a particular application dictates otherwise, RKI
Instruments, Inc. recommends a calibration frequency of every 3 months.
If an application is not very demanding, for example detection in a clean, temperature
controlled environment where CO is not normally present and calibration adjustments are
minimal at calibration, then a calibration frequency of every 6 months is adequate.
If an application is very demanding, for example if CO is present often and in significant
concentrations or the environment is not well controlled, then more frequent calibration
than every 3 months may be necessary.
