Instruction Manual PUC 28326.2 Error codesAfter sending a command the following error messages are possible:No. Error message Description1 Err_CmdNotExist An unknown command has been sent to thePUC 28.2 Err_ValRange The transfered parameter value is outside it’svalid limits. This might happen also (amongother things), if a top value is smaller or equalthe associated bottom value.The error will also be generated after a re-calibration of a PUC 28/K, if the calibrationvalue differs more than ±30% of the factorycalibration.3 Err_NotActive - It was tried to read a measured value of achannel which is currently switched off.- It was tried to cancel a re-calibration,although no re-calibration is running(concerns only the variants PUC 28/K).4 Err_Underflow The measured value is below the bottommeasurement limit.5 Err_Overflow The measured value is above the uppermeasurement limit.6 Err_ZPCC_active Currently a re-calibration is not possiblebecause of a running zero-point calibration.Possibly suppress any zero-point calibrationbefore re-calibration with the command“>CMD 1” (concerns only the variants PUC28/K).
