ERROR DESCRIPTION
WHAT TO DO
OVER RANGE U
The input exceeds 105 %.
Adjust the input signal in order not to exceed 105%.
OVER RANGE D
The input exceeds lower limit of -5 %.
Adjust the input signal in order not to be lower than -5%.
SCALING ERROR U
Input or output scaling value exceeds
999999 (upward).
Adjust the input signal for the input scaling not to exceed
999999.
SCALING ERROR D
Input or output scaling value exceeds
-99999 (downward).
Adjust the input signal for the input scaling not to be lower
than -99999.
INTERNAL ERROR
Internal error
First, reset the power.
If the error is not corrected, activate ‘Reset all settings” to
reset all settings to the initial values.
If the error is still not corrected, the unit needs a repair.
Indicated errors vary as follows depending on the setting values of display setting.
Error is indicated with blinking at the upper or lower part of the display.
When multiple errors occur, only the highest-priority error is displayed.
The 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) Power input voltage: Check voltage across the terminal
19 – 20 with a multimeter.
3) Input: Check that the input signal is within 0 – 100% of
the full-scale.
4) Output: Check that the load resistance meets the de-
scribed specifications.
