FieldInstallation
It is relatively easy to install RTUs in the field. You can perform a
connectivity check with an LED tool, an example of which is shown in
Figure 2.
Figure 2. LED Tool
Note: The LED tool is a blind plug to be connected to the POWER connector.
Follow these steps to install Adcon’s RTU in the field:
1. Review the installation area and choose the best site.
2. Perform a connectivity check using the LED tool:
a. Insert the LED tool into the POWER connector and wait up to
10 seconds. If the unit connects to at least one station (or a
base station), it will light up the LED for about four seconds.
b. Keep observing the LED tool and, after another several
seconds, the LED will blink one or more times (the number of
blinks indicates the number of stations it has contacted).
3. Unpack the pole set.
4. Using a sledge hammer, drive the base pole (pointed tip) into the
ground until it is securely and tightly seated. To prevent damage
to the top of this pole make sure to put a protective cap on top of
it prior to pounding it in. Such a pole pounder can be ordered
from your Adcon distributor (item number 900.000.014).
5. Using a ring clamp, fasten the solar panel onto the aluminum
pole. Make sure that the panel is facing south (north if you are
located in the southern hemisphere) and out of the way of the
RTU.
Note: The solar panel can be mounted under or behind the RTU, but be sure
that the RTU does not shadow the panel.
6. Fasten the RTU to the top of the pole using another ring clamp.
Adcon recommends that you perform another connectivity test, if
you can, to check the positioning of the device.
 WARNING If you turn the fastening screws too tightly, you might damage the
plugs.
7. Attach the sensors to the INPUT connectors and the solar panel to
the POWER connector by turning the plugs’ fastening screws
clockwise until secure.
8. Secure the extra length of the sensor cables to the pole with UV
resistant cable ties.
