14. Reinstall sensor. Refer to:
Section 7.28.5
- For STS and SRS Reinstallation
Section 7.28.6 - For RRS and RTS Reinstallation
Section 7.28.7 - For DTS Reinstallation
Section 7.28.8 - For ETS1 and ETS2 Reinstallation
NOTE
The P5 Pre-Trip test must be run to deactivate probe alarms (see Section 5.8 ).
7.28.5 Sensor STS and SRS Reinstallation
To properly position a unit supply sensor (Supply Temperature Sensor STS or Supply Recorder Sensor SRS), the
sensor must be fully inserted into the probe holder. This positioning will give the sensor the optimum amount of expo
-
sure to the supply air stream, and will allow the Controller to operate correctly. Insufficient probe insertion into the
probe holder will result in poor temperature control due to the lack of air flow over the sensor.
It is also necessary to ensure that the probe tip does not contact the back panel. The design minimum clearance of
6 mm (1/4 inch) should be maintained (see
Figure 7.34
).
