ERROR MESSAGES
DISPLAY ERROR DESCRIPTION WHAT TO DO
OVER RANGE U The input exceeds 105 %. Return the input signal not exceed 105 %.
OVER RANGE D The input exceeds lower limit of -5 %. Return the input signal -5 % or more.
SCALING ERROR U Input or output scaling value exceeds
999999 (upward). Return the input or output signal not exceed 999999.
SCALING ERROR D Input or output scaling value exceeds
-99999 (downward). Return the input or output signal not lower than -99999.
SETTING ERROR Setting value error Return the setting value to normal value.
EEPROM I ERROR Internal data error Repair is needed if the display does not recover after the
power is reset.
EEPROM R ERROR Memory reading error ‘Reset all settings’ in advanced mode.*
1
EEPROM W ERROR Memory writing error ‘Reset all settings’ in advanced mode.*
1
*1. All setting parameters are initialized. Repair is needed if it does not recover.
Indicated errors vary as follows depending on setting value of display setting.
Error is indicated blinking at upper or lower.
When multiple error occurs, only high priority error is displayed.
Order of priority is EEPROM ERROR, OVER RANGE, SCALING ERROR in descending order.

CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Check DIP switch setting.
3) Power input voltage: Check voltage across the terminal
10 – 11 with a multimeter.
4) Input: Check that the input signal is within 0 – 100% of
the full-scale.
5) Output: Check that the load resistance meets the de-
scribed specifications.
