Due to the modular design of the Type TB82TE transmitter, the replacement of an assembly can be easily completed. Replacements are available for each major assembly. These include the two-electrode conductivity input PCB, microprocessor PCB, power supply PCB, front bezel, shell, and rear cover assemblies. This section does not contain repair instructions for the sensor. Refer to Section 12 for diagnostics and troubleshooting information. Due to the nature of its design, if the troubleshooting procedures do not solve the problem, complete sensor replacement is required when it has been damaged or does not properly function. REPAIR AND REPLACEMENT SEQUENCE Refer to Figure 14-1 for the repair sequence for the transmitter. 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 repair. 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. WARNING Do not substitute any components other than those listed in the appropriate procedures. Doing so will compromise the certification listed on the transmitter nameplate. Invalidating these certifications can lead to unsafe conditions that can injure personnel and damage equipment. Do not disconnect equipment unless power has been switched off at the source or the area is known to be nonhazardous. Disconnecting equipment in a hazardous location with source power on can produce an ignition-capable arc that can injure personnel and damage equipment.
