When the power is turned ON for the first time after a separately purchased Out-
put Unit is mounted to the K3Nj, the following messages will be displayed.
Follow the procedures below to clear the messages.
Meaning of Message:
This message is displayed when the power is turned ON after an Output Unit is
mounted or replaced.
It is also displayed when there is an error in the internal circuitry.
Remedy:
Press the Mode Key for less than 1 second. The K3Nj should enter RUN mode.
In this case, a malfunction has not occurred.
If chg o continues to be displayed, turn the power OFF and ON again. If the
K3Nj still fails to enter RUN mode, repairs are necessary. It is possible that
noise has caused faulty operation.
Meaning of Message:
This message will be displayed when the power is turned ON and either an in-
compatible Output Unit has been mounted on the K3Nj or an Output Unit has
not been mounted on the K3Nj with set value LED display.
It is also displayed when there is an error in the internal circuitry.
Remedy:
Check that the Output Unit is compatible, and if it is not, turn OFF the power and
replace it with a compatible one. If an Output Unit is not mounted on the K3Nj
with set value LED display, turn OFF the power and mount a compatible Unit.
When the power is turned ON again, chg o will be displayed. If the Mode Key is
pressed for less than 1 second, the K3Nj should enter RUN mode. In this case,
a malfunction has not occurred.
If err o or chg o is still displayed, turn the power OFF and ON again. If the
K3Nj still fails to enter RUN mode, repairs are necessary. It is possible that
noise has caused faulty operation.
