Execution Error
The code is divided into two parts which are displayed alternately on the 7-segment LED;
in the first part, the letter E appears in the left digit with the hundreds digit of the error
code to the right, and the second part consists of the last two digits of the error code.

E203 Cannot execute when in measurement mode. Change the mode before execution.
E204 Cannot change or execute while saving to memory. Stop the save operation before executing.

E211 No relays for communication input found. Check installation of relays and the relay output types.
E212 Initial balance failed. Check the settings and wiring.
E213 No channels for initial balance found. Check the target channels.
E214 No channels for transmission output found. Specify channels for transmission output.
E215 No channels for arbitrary output found. Specify channels for arbitrary output.
E221 No measurement channels found. Check the measurement module, measurement group number,
measurement interval, and other settings.
E222 Invalid measurement interval. Set the measurement interval so that: Meas. gr 1 ≤ meas. gr 2
≤ meas. gr 3
E223 Too many measurement channels. The number of measurable channels during 10 ms
measurement is 10, and for 50 ms measurement, 30.
E224 No MATH channels found. Check the MATH channel settings.
E225 Invalid MATH interval. Set the MATH interval to measurement groups of 100 ms or
more. When measuring with measurement modules, set the
measurement group numbers on which to perform
measurement.
E226 Cannot start/stop MATH operation. Cannot execute because MATH start is set for the level
detection action.
E227 Cannot start/stop recording. Cannot execute because recording start is set for the level
