EPOTOFST
Manual entry of Potential Sensor offset
Lv.1 Details
To set the offset auto adjustment value of Potential Sensor manually.
As the value is incremented by 1, the offset value changes by 1V.
+: Identified as the lower potential than the detected one
-: Identified as the higher potential than the detected one
Use case
When an error is displayed by executing OFST (auto offset
adjustment) at the replacement of Potential Sensor (When the value
out of specified range is set due to Potential Sensor disconnection/
connection failure/installation failure), restore to the factory setting
values.
1) To stop the error, set 0 (V) in EPOTOFST.
2) Check around the Potential Sensor.
If there is an error, address it and if not, go to the step 3).
3) Enter the value of service label.
4) If image fogging or the like occurs, increase the value by 10V
increment.
