Troubleshooting
Section 14 - Troubleshooting
The RD1500 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.
14.1 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.
14.2 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.
