Incorrect connection and/or termination resistor fitted to K-Bus of wrong value or
missing altogether.

Real time clock corruption
The battery within the KITZ 101, 102 is provided to maintain the real time clock
to the correct time following an interruption of the ac/dc voltage supply to the
unit. Corruption of the real time clock can occur if the voltage across the battery
drops below the accepted minimum level and an interruption in power supply
takes place. This may be evident by invalid real time clock data within the
Courier response message of the slave devices connected to the unit. The voltage
across the battery should be measured with the supply voltage removed and if
found to be less than 3.5V, the unit should be returned to AREVA T&D for
replacement of the battery.
