Refer to Section 6 BCD Output.
Refer to the Communications Manual.
Refer to the following for the relationship of the number of output counts versus
the number of input counts and the prescaling value.
Count value = Number of input counts x Prescaling value
For example, if the prescaling value is 0.01, 100 counts will be counted as a
single unit (i.e., count value = 100 x 0.01 = 1).

This function keeps the process value at the time of power failure. This function
is enabled or disabled with K3NC setting.
Teaching
Output Test
The K3NC is provided with a teaching function that can set an actual measured
value as a setting value without key input.
This function is useful for setting parameters while checking the operating status
of the K3NC.
The teaching function can be used to set the set and scaling values. It can be
also used to set the linear output range of the K3NC with a Linear Output Board.

First, check the following three items if the K3NC has any problems during operation.
1, 2, 3... 1. Power Supply
Be sure that power supplied to the K3NC is within the rated voltage range.
2. Wiring
Be sure that the K3NC is wired correctly.
3. Communications Conditions
If the model is a K3NC with the Communications Output Board, be sure that
the baud rate and unit numbers are correct.
After checking and remedying the above items, if the K3NC still has problems
during operation, check the error message.
7-2 Display
7-2-1 Flashing
The display will flash in the following cases.
• The input or process value is not within the display range.
If the display flashes the output status will be as follows:
Models with BCD Output Board: The OVER signal will be ON.
Models with Communications Output Board: The OVER or UNDER signal
will be ON and other output signals will be retained.
• The display will flash for three seconds if an attempt is made to change a setting on the K3NC. Set to remote programming to accept key input.
