What does the error T LIMIT ? on my ProMinent DULCOMETER Controller mean?
- DDerek MurphySep 9, 2025
The 'T LIMIT ?' message means that the correction variable falls below the lower set limit.
What does the error T LIMIT ? on my ProMinent DULCOMETER Controller mean?
The 'T LIMIT ?' message means that the correction variable falls below the lower set limit.
What does CAL ERROR mean on ProMinent Controller?
The 'CAL ERROR' indicates that no valid user calibration exists.
What does NO CAL mean on my ProMinent DULCOMETER Controller?
The 'NO CAL' message indicates that no valid user calibration exists.
Why does my ProMinent DULCOMETER Controller display 'pH/mV RANGE'?
The 'pH/mV RANGE' error on your ProMinent Controller can appear if the input voltage is either too low or too high, indicating a fault current.
What does 'NO CAL' mean on my ProMinent DULCOMETER Controller?
The 'NO CAL' message on your ProMinent Controller means that no valid user calibration exists.
What does TLIMITERR mean on a ProMinent Controller and how to fix it?
The 'TLIMITERR' indicates that the set checkout time for monitoring the correction variable limits has elapsed. The suggested solution is 'Fault current'.
What does it mean when my ProMinent DULCOMETER Controller displays 'NO PROBE'?
The 'NO PROBE' message on your ProMinent Controller indicates that there is no sensor detected, assuming pH sensor monitoring outputs are activated.
Why does my ProMinent DULCOMETER Controller display 'T RANGE'?
The 'T RANGE' error on your ProMinent Controller indicates that the measured temperature is either beneath or above the measuring range, which can result in a fault current.
What does T LIMIT ? mean on a ProMinent DULCOMETER Controller?
The 'T LIMIT ?' message indicates that the correction variable exceeds the upper set limit.
Why am I seeing T RANGE ? on my ProMinent DULCOMETER Controller?
The 'T RANGE ?' message on your ProMinent Controller means the measured temperature is above the measuring range. The suggested solution is 'Fault current'.
