Troubleshooting
Section 11 - Troubleshooting
The RD1100 system is designed to minimize user problems; however, all electronic devices are
subject to possible failure. The following are troubleshooting hints which can be referred to if
your system fails to operate.
11.1 Power Supply
The most common problem that can occur while trying to run the system is insufficient power.
The battery may be dead, have a low voltage or the fuse may be blown.
Once boot up is complete, the color of the LED (see Figure 5-1) indicates the amount of battery
power remaining:
You can check the battery voltage with a voltmeter. Try to do this while the system is still
attached to the Cart to get a true measure of the voltage while under load (it will be necessary to
open the battery case and connect the voltmeter to the positive and negative battery terminals).
A fully charged battery will show a voltage of 13.8V, whereas a voltage of 10.8V or lower will not
power the system. If the battery has a low voltage or seems dead, try using another battery (if
available), or give the battery a good 12-14 hour charge and try running the system again.
If the battery does not charge up to 12 Volts or more, it should be replaced.
Batteries are fused to protect the system. Open the battery case and check that the 10 Amp
fuse is OK. If necessary, replace it with one of the spare fuses available inside the battery case.
If the battery seems OK but the system still does not power up, check the battery cable
connections and inspect the battery cable for damage.
11.2 System Communications
If the battery is OK and the Display Unit turns on but the GPR sensor does not scan, there may
be a communication failure between the Display Unit and the GPR sensor. If an error occurs, an
error message will appear. Power Off the system and disconnect the battery.
Make sure the display cable is not damaged, all pins are straight, and there is no dirt or debris in
the connector. Ensure that the cable connections are tightly secured. Vibrations can sometimes
cause the cable connections to loosen slightly and break contact, leading to errors.
Disconnecting the cable and reconnecting it may provide a better contact and solve the
problem. Plug in the battery, turn on the system and try scanning again.
If the Battery, Battery Cable and Display Cable are OK, the problem is either a failure of the
Display Unit or the GPR sensor. These units have no user-serviceable parts so they will have to
be returned to the vendor for inspection and repair.
