2.15 Oil management device – OM5 TraxOil™
The compressors in the Copeland CO
OM5 TraxOil oil level management system. This device is intended to prevent the compressors from
operating with insufficient oil by opening a valve which allows the oil to flow from the oil separator to
the compressor. The OM5 uses a hall sensor to measure the oil level. Unaffected by foaming oil or
light, a magnetic f loat changes its position according to the oil level. The hall sensor converts the
magnetic field changes into an equivalent signal, which is used by the integrated electronic controller
to monitor and display the actual oil level with LEDs.
In case of low oil level and after a delay time of 20 seconds the OM5 will generate an alarm which
will make the unit controller stop the compressor immediately.
This alarm can be displayed on the Visotouch like any other alarm of the unit.
Figure 35 below depicts the sight glass level control zones. Table 14 describes the LED code legend.
Figure 36 shows the OM5 TraxOil mounted on the compressor.
