6.5 Troubleshooting
6.5.1 What Should Always be Checked Regardless of the
Problem
Always check the incoming AC voltage to the weather station. It should always
be 17 VAC or higher. AC voltage from the transformer should be going to the
two terminal blocks in the enclosure marked “CHG”. There is no polarity.
Check to make sure that all plugs are connected to the back of the enclosure.
Measure the 12 VDC voltage across the two terminal blocks marked “12 V”
and “G”. Also check the voltage at the battery. These voltages should be
identical. The voltages should be somewhere between 13.2 and 14.0 VDC.
The voltage from the charging circuitry is temperature dependent—the higher
the air temperature the lower the charging voltage.
AC power or the charging circuitry has been lost if the voltage
measured is 12.5 VDC or less. The datalogger needs a minimum
of 9.6 VDC to operate. The battery cannot be deep discharged.
Once voltages get below 11.0 VDC the battery is damaged and
will never take a full charge!
Always verify there are no loose wires. Give each wire going to a terminal
block a gentle tug to see if it easily pulls out. If it does, then make sure the
terminal block is clean and free of debris and reinsert the wire. IF VOLTAGE
IS PRESENT, BE CAREFUL NOT TO SHORT THE WIRE AGAINST THE
ENCLOSURE OR OTHER WIRES.
6.5.2 Identifying What is Wrong with the Station
If the Toro software is NOT receiving data:
1.
See Section 6.5.3 “Power Supply Problems”
2.
See Section 6.6 “Communication Problems”
If the Toro software is receiving data, but some of the data looks wrong or out
of range:
1.
See Section 6.5.3 “Power Supply Problems”
2.
See Section 6.7 “Sensor Problems”
3.
See Section 6.8 “ToroPro” if you are using the Campbell Scientific
ToroPro software package.
