6. E8 CONTROLLER FAILURE CODES
The Failure Codes that may appear in the Controller display during operation of the Modulex Boiler are
described in paragraph 6.1. In addition, paragraph 6.2 provides the procedure to be followed to clear a
displayed failure code after the cause of the failure has been corrected.
6.1 FAILURE CODES AND DESCRIPTIONS
Failure codes are divided into four basic categories: PCB Element Failures, System Manager Failures,
Communication Errors and Internal Errors. These codes are listed and described in Table 6-1.
