bad calibration and returns to the beginning of the calibration cycle. The transmitter reports a bad temperature calibration and rejects calibration values for slope values less than 0.2 or greater than 1.5 and offset values less than -40-degrees Celsius or greater than +40-degrees Celsius. Temperature calibrations use smart software routines that automatically adjust the value for slope, offset, or both based on the calibration value being entered and the calibration history if it exists. ADDITIONAL DIAGNOSTICS Other diagnostic messages may appear during transmitter programming. These messages include BAD.VAL (bad value), DENIED, and RAM.ERR (RAM error). BAD.VAL indicates the attempted numeric entry of a value out of the allowed range of the transmitter. Table 1-3 lists the transmitter range limits. DENIED indicates incorrect entry of a security password. Section 9 contains information on security. RAM.ERR indicates a RAM read/write error. The transmitter automatically resets when this error has been encountered. If the transmitter continues to reset, contact ABB for problem resolution. TROUBLESHOOTING SEQUENCE Refer to Figure 12-1 for the transmitter troubleshooting sequence. Each block of the flow represents a single task that must be completed before continuing with the sequence. In some cases, more than one path can be taken during troubleshooting. For paths that are in parallel, either complete all of the tasks in all of the paths before continuing or complete all of the tasks in only those paths that apply before continuing. At least one path must be completed. Some blocks contain alphanumeric codes. These codes identify the procedure that describes the steps to complete an indicated task. Complete all of the steps given in a procedure before continuing to the next procedure. The procedures have check boxes in the margin by each procedural step. When performing a procedure, check each box as each step is completed. By treating each task as a separate entity, the procedures provide an easy method for finding the information n
