Barometer
The barometer sensor is mounted within the 6200 DCP, it is vented to the outside via a small
tube right next to the antenna connector.
SYMPTOMS POSSIBLE CAUSE ACTION REF
Hello signal not present Disconnect the barometer cable
from the 6200 DCP interface
board. Use a multimeter or DVM
to check the barometer connector.
Pin 5 to 6. Pin 5 should measure
3.5 volts DC or higher in
reference to ground or pin 6. If
voltage is not present, the 6200
DCP will not detect the
barometer.
Return unit to factory. 5
The barometer connector hello
signal is present on pin 5. Check the barometer
cable/connector for continuity
between pin 5 to 6, it should be 0
ohms
Return unit to factory 5
Barometer
During setup the
Barometer sensor is
not detected by the
EcoWatch 6200
configuration
wizard
The barometer connector
Hello pins indicate 0 ohms 6200 DCP electronics input
digital port damaged.
Return 6200 DCP to factory. 5
No barometric
pressure displayed Excitation voltage is present
and hello loop is OK Replace or return Barometer to
the factory 5
For accurate data from the solar radiation sensor a coefficient entry is required during the
configuration wizard.
Solar Radiation
The Pyranometer is connected through its own connection on the bottom of the 6200 DCP. It
generates a small signal based on solar radiation.
SYMPTOMS POSSIBLE CAUSE ACTION REF
Hello signal is not present Disconnect the sensor cable from
the 6200, use a multimeter or
DVM to check the Solar
connector, pin A to B The voltage
should be 3.5 VDC or greater. 5.4 Solar Radiation
During setup the
Pyranometer sensor
is not detected by
the EcoWatch 6200
configuration
wizard
Hello signal is present, but
sensor is still not detected. Check pins A to B for 0 ohms
continuity.
If it is open return unit to factory. 5.4
