Sentek SOLO distributors can provide a regular maintenance program which consists of regular visits by an
authorized installer to test and ensure correct operation of the system. A regular maintenance program such as
this will ensure that the Sentek SOLO system functions properly and continues to give worry free operations.
Probe
The Sentek SOLO probe electronics should be kept free of moisture, dust and insects. If any of these things are
found to have entered the access tube they should be removed and the entry point resealed immediately.
The probe top cap should be checked regularly for cracks or breakages. Machinery should be kept well away
from the probes. This will avoid damage to the probe rods as well as preventing compacting of the soil around the
probe, thus giving a false indication of the soil moisture content.
EasyAG probes should have the top cap gasket replaced each time the cap is removed.
Cable
Regular inspection of the cabling for damage caused by insects, animals or machinery should be carried out. If
necessary the cable can be elevated and/or covered to protect it from potential damaging elements.
A break in the outer sheath of the cable can be an entry point for moisture into the probes access tube.
Corrosion on the wires within the cable can cause a drop in voltage between the Solo Head Unit and the probe.
Use a volt meter to test the voltage at each end of the cable to be sure this is not an issue.
Head Unit
The Solo Head Unit should be elevated off the ground, out of the canopy, and out of the way of machinery to
prevent any breakage, moisture or insect intrusion. For maximum prevention of moisture intrusion, mount the
Head Unit on a slight angle so water can run off and place a bead of silicon along the join of the Head Unit.
Never submerge the Head Unit and avoid opening it.
Ensure that protective cap is always screwed on straight and tight when not downloading to prevent damage to
the download port.
Batteries
Solo Head Unit batteries should be monitored in the IrriMAX software to give an indication of when the batteries
need to be replaced.
The graph in Figure 9 shows the typical curve of the voltage graph from a Sentek SOLO system. It should be
noted that the actual life of the system may be less than shown. Factors such as sample frequency, ambient
temperature, battery age, manufacturer, quality and other unpredictable factors could have an adverse effect on
the life of the battery.
Corrosion caused by moisture intrusion on the probe electronics, cable wires or inside of the Solo Head Unit can
also have an adverse effect on battery life. Keep components corrosion free by performing regular maintenance
as described in this manual.
