RD1000™ Operation Manual 35
5.2 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 blow out the connector sockets as small debris may block
individual pin connections and disrupt communications. Ensure that
the cable connections are tightly secured. Sometimes vibrations
cause the cable connections to loosen just a bit and break
contact and this can cause 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 it will have to the vendor for
inspection and possible repair.
5.3 System Overheating
The GPR system is designed to operate to a maximum internal
temperature of 70 C or 158 F. In situations of high ambient
temperatures or long exposure to direct sun, this maximum internal
temperature may be exceeded and cause the system to fail.
If you suspect that the GPR sensor is overheating, shut it off and
give it a chance to cool down in a shady location before trying to
run it again. Placing a wet cloth on top of the GPR may help in
cooling it down.
If the situation is such that the high temperatures or direct sun
cannot be avoided, it may be a good idea to put some sort of shade
over the GPR sensor.
