Teaching with actual values is possible.
Instead of setting by inputting with the
Up Key and
Shift Key, current values can be
input as scaling input values for teaching. This is useful for making settings while checking the
operation status of the K3MA-J.

The parameters (inp.1, inp.2) for the K3MA-J’s initial setting level can be set using actual input values with the teaching function. After displaying
the parameters, the actual input settings can be made with the following operation.

OUT Types (Comparative Output Models Only)
OUT 1 and OUT 2 can be set to operate in one of the three following modes in accordance with the compared values:
• Upper limit (High Acting):
The output is turned ON when the measurement value is greater than its set value.
• Lower limit (Low Acting):
The output is turned ON when the measurement value is less than its set value.
• Upper and lower limits (Outside Band Acting):
An upper limit (H set value) and lower limit (L set value) can be set independently.
The output is turned ON when the measurement value is greater than upper-limit set value or less than the lower-limit set value.

Parameter Initialization
Changing the Display Color
This function returns all of the parameters to their initial values.
The color of the value displayed can be set to either red or green. For
comparative output models (K3MA-J-A2), the display color can be
set to change from green to red, or from red to green, according to
the status of the comparison criterion.

Average Processing
OUT2 value
Average processing stabilizes displayed values to minimize flicker by
averaging the fluctuating input signals. Average processing can be
performed for the measurement values in either of four steps (OFF, 2
times, 4 times, or 8 times).

Display Auto-return Time
This function automatically returns the display to the operation level’s
current value if no keys are pressed for a preset time (called the display auto-return time).
This is useful for ignoring rapid fluctuations, e.g., eliminating spike
noise.
Hysteresis (Comparative Output
Models Only)
The hysteresis of comparative outputs can be set to prevent chattering in the output when the measurement value fluctuates finely near
the OUT value.
Move-to-Protect-Level Time
The time required to shift to the protect level can be set as desired.
Forced-zero Function
It is possible to shift from a value to the zero point with one touch of
the Up Key on the front panel (for example, when adjusting reference
values).

Installation
1. Insert the K3MA-J into the panel cut-out hole.
2. For a waterproof installation, insert the rubber gasket onto the
body of the K3MA-J.
■ Rubber Packing
K32-P1
If the rubber packing is lost or damaged, it can
be ordered using the following model number:
K32-P1.
(Depending on the operating environment, deterioration, contraction, or hardening of the rubber
packing may occur and so, in order to ensure
the level of waterproofing specified in NEMA4,
periodic replacement is recommended.)
Note: Rubber packing is provided with the
Controller.
3. Fit the adaptor into the grooves on the left and right sides of the
rear case, then push it until it contacts the panel to secure the
K3MA-J.
■ Wiring Precautions
• Use crimp terminals.
• Tighten the terminal screws to a torque of approximately 0.5 N⋅m.
• To avoid the influence of noise, route signal lines and power lines
separately.
■ Wiring
• Use the following M3 crimp terminals.
5.8 mm max.
■ Angle of View
The K3MA is designed to provide the best visibility at the angles
shown in the following diagram.
5.8 mm max.
■ Unit Labels (Provided)
• The unit labels are not attached to the K3MA-J. Select the desired
labels from the provided sheet.
