K3MA-J
■ Setting Example
Initial Settings
The settings for the following example are shown here.
Example: Tank pressure display
Here, the pressure inside the tank is to be displayed in units of 0.1
kPa.
• Pressure Sensor
Measuring range: 0 to 980 kPa, output 4 to 20 mA
1. Set the K3MA-J input type to the 4 to 20 mA input range.
Parameter: in-t (input type), Setting value: 4-20
2. Set the display values for the corresponding input values.
Set the scaling as shown below for the following correspondence:
input 4 mA-->display 0.0, input 20 mA-->display 980.0
Parameter Setting value
inp.1 (scaling input value 1) 4.00
dsp.1 (scaling display value 1) 00000
inp.2 (scaling input value 2) 20.00
dsp.2 (scaling display value 2) 09800
dp (decimal point position) %%%%.%
Note: The decimal point position here refers to the position in the
number after scaling. When setting the scaling display value, it
is necessary to consider the number of digits to be displayed
past the decimal point.
■ Troubleshooting
When an error occurs, error details will be displayed on the main indicator. Confirm the error from the main indicator and take the appropriate coun-
termeasures.

Not lit e111 RAM memory error Repair is necessary.
Consult your OMRON sales representative.
5e111 EEPROM memory error When this error is displayed, press the Level Key for 3 sec-
onds, and the settings will be restored to the factory set-
tings.
If the error cannot be recovered, repair is necessary. Con-
sult your OMRON sales representative.
Not lit Flashes s.err You will see this indication when turning ON the
product the first time after purchase. This is be-
cause the input signal value is 0 mA at that time
even though the range is factory set to 4 to 20 mA.
For the K3MA-J-A2, the relay output will be OFF.
At the initial setting level, set the input type and other pa-
rameters according to your application.
Input error Promptly change the input voltage/current to a value that
falls within the measurement range.
If the error cannot be recovered, repair is necessary. Con-
sult your OMRON sales representative.
Not lit Flashes 99999 The scaling display value exceeds 99999. Promptly change the input to a value that falls within the
specified range.
The scaling value may be inappropriate. Review the scal-
ing value at the initial setting level.
Not lit Flashes The scaling display value is lower than −19999. Promptly change the input to a value that falls within the
specified range.
The scaling value may be inappropriate. Review the scal-
ing value at the initial setting level.
