Troubleshooting
Noggin Smart Systems are designed to minimize user problems; however, all electronic
devices are subject to possible failure. The following are troubleshooting hints in the
likelihood of occurrence if your Smart System fails to operate.
7.1
Power Supply
The most common problem that can occur while trying to run a system is insufficient
power. The battery may be dead or have a low voltage. If the system is being run from
AC, there may be a problem with the AC power supply or adapter.
If there is enough power to run the DVL, the upper red LED on the front of the DVL will
light up when the battery is plugged into the system. If this light is on and the DVL boots
up, runs and displays the main menu, next check that the red light on the connector to
the Noggin is on. If this light is off then there is a problem with the connection from the
DVL to the Noggin. Check the connection and this part of the cable.
If the DVL is running but the Noggin system will not run, go to the main menu and check
that battery voltage in the lower left corner (see Section 4) is above 10.5 volts. If not, the
battery needs to be recharged or replaced for the Noggin to run (see below).
If the battery voltage is less than about 10.5 volts, the DVL may not turn on and the
upper red LED will flash or not illuminate.
Check the battery voltage with a voltmeter. Try to do this while the system is still
attached to the Smart System to get a true measure of the voltage while under load (it
will be necessary to open the Smart Cart battery case and connect the voltmeter to the
positive and negative battery terminals). If the battery has a low voltage or seems dead,
try the system with 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.
Smart System batteries are fused to protect the system. For the Smart Cart 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. The smaller belt batteries
available for the Smart Handle systems are also fused. Remove the battery from
padded casing and check the 5 Amp fuse. Replace the fuse if necessary.
7.2
System Communications
If the system power supply is OK but the Noggin does not respond there may be a
communication failure between the DVL and the Noggin. This type of failure is often
indicated by a 10000 series error number like 10012.
