ERROR MESSAGES

DISPLAY ERROR DESCRIPTION
OVER RANGE U The input exceeds 105 %.
OVER RANGE D The input exceeds lower limit of -5 %.
SCALING ERROR U Input or output scaling value exceeds
999999 (upward).
SCALING ERROR D Input or output scaling value exceeds
-99999 (downward).
SETTING ERROR Setting value error
EEPROM I ERROR Internal data error
EEPROM R ERROR Memory reading error
EEPROM W ERROR Memory writing error
*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.
