PDP401
ETable 12-3 contains all the error codes supported by the transmitter. Each entry lists the error code number, displayed text string, and a short description of the fault condition. When an error code appears on the transmitter display, the transmitter must be replaced with one that is known to be operable. Return the nonfunctional transmitter to ABB for repair. Contact ABB for processing instructions. CALIBRATION DIAGNOSTICS The transmitter performs automatic efficiency and offset calculations. These calculations are relative to a theoretically perfect conductivity and temperature sensor and are conducted after each calibration cycle. Calibration history is retained for future interrogation using the edit calibrate state. The calibration constants displayed are slope and offset for the PV and temperature. A slope of less than 0.2 or greater than five for the PV indicates a potentially bad process calibration point or poorly performing sensor. In these cases, the text string BAD.CAL appears on the secondary display. The transmitter returns to the beginning of the calibration cycle after it reports the bad calibration. An offset value of less than -20 or greater than +20 microsiemens per centimeter for a nominal sensor cell constant value of 1.00, less than -4 or greater than +4 microsiemens per centimeter for a nominal sensor cell constant value of 0.10, and less than -0.8 or greater than +0.8 microsiemens per centimeter for a nominal sensor cell constant value of 0.01 also indicates a potentially bad process calibration or poorly performing sensor. In these cases, the tra
