Why is my Fuji Electric Temperature Controller not controlling properly?
- M
  Maria BrownAug 17, 2025
  If your Fuji Electric Micro-controller is not controlling properly, it might be due to incorrect set values of the parameters , , P and . To fix this, perform the auto-tuning. Also, if the cycle times are too long, decrease the set value of the parameters and gradually. If the output is limited, set the parameters , , and again to be suitable for the process. If the output is not limited correctly, set the parameter again to be suitable for the process.

What to do if auto-tuning doesn't work on my Fuji Electric Temperature Controller?
- S
  Susan SmithAug 20, 2025
  If auto-tuning does not work properly on your Fuji Electric Temperature Controller, it could be due to several reasons: * The display shows or after starting auto-tuning. To fix this, make the difference of the set values of and larger, and perform the auto-tuning again. * You changed the SV after starting auto-tuning. Set the desirable SV and perform the auto-tuning again. * You tried to perform auto-tuning during ramp-soak operation. Set the parameter to , and perform the auto-tuning again. * Peripheral devices have problems or are not connected properly. Connect them properly.

What to do if ON/OFF control is not functioning properly on my Fuji Electric Temperature Controller?
- M
  Mark ZamoraAug 26, 2025
  If ON/OFF control is not functioning properly on your Fuji Electric Temperature Controller, it could be due to an incorrect set value of parameter . Adjust the set value of parameter to be suitable for the device to be controlled. Alternatively, the setting of parameter might be incorrect, so set the parameter correctly.

Why has the SV or set values changed on my Fuji Electric Temperature Controller without any operation?
- D
  David GreenAug 28, 2025
  If the SV or set values of some parameters have been changed on your Fuji Electric Temperature Controller without any operation, it could be because the parameter of , , or was changed. Reset all the parameters again. Another cause can be when the set value of is larger than 1000, "1" is registered for . Set to "0", and return to an original value.

Why is the response too slow on my Fuji Electric Temperature Controller?
- C
  czimmermanAug 30, 2025
  If the Fuji Electric Temperature Controller response is too slow, meaning the measured value changes slowly, it is likely that the input filter constant is too large. To resolve this, decrease the set value of the parameter .

How to fix SV if it cannot be changed on Fuji Electric PXR3?
- K
  Kelly BlakeSep 3, 2025
  If the SV cannot be changed on your Fuji Electric Temperature Controller, it could be because "1", or "4" is set in the parameter . Set the parameter to "0", "2", "3" or "5". Another reason could be that you have tried to set a value outside of the measuring temperature range. Widen the range to . You might also have tried to change the SV during ramp-soak operation. Set the parameter of to .
