What does it mean if [OL] or [-OL] is displayed on my Minebea Touch Panel, or the load value display is unstable?
- KKathryn WebbSep 23, 2025
If you see [OL] (overload status) or [-OL] (unstable status) on your Minebea Touch Panel, or the load value display is unstable, it could be due to several reasons. The strain gage based transducer may be faulty, so try using another one. The transducer might be incorrectly wired, so ensure it is correctly wired. The signal line of the transducer could be broken, so check its wiring status. The input from the transducer may be beyond the range of ±3.1 mV/V, so check the input. Calibration may have been improperly executed, so try executing it again. Finally, the voltage between A and C of CSD-912B might be unstable; measure the voltage between A and C to ensure it is stable at the setting value of the excitation voltage.
