Page 19: Error Notification
6.2 Error Notification The LCD panel lists the last detected errors using a sequence of double-digit codes. A 00 state code denotes the absence of errors, whereas a non-zero state code denotes one or more errors. See Section 6.2.1 for a list of the error codes. The error format is shown in Figure 6—18. -

Page 24: Air Filter Cleaning
8 AIR FILTER CLEANING The product draws air from the bottom and expels it on the right-hand side. The intake air is filtered to remove the largest particles, so depending on environmental conditions the air filter may need occasional cleaning. The outlet filter may also require attention. A higher temperature in zone two can be an indication that such action is required. -
Page 25: Figure 8-2: Metallic Hood
To clean the air outlet filter: 1. Slide up and remove the metallic hood on the right-hand side of the product casing to reveal the black fan / filter assembly. Note: Use a rubber mallet to assist with removing the hood. 2. -
Page 26: Oil Filter Cleaning
9 OIL FILTER CLEANING The oil is filtered to prevent particles from entering the product or being returned to the transformer. Therefore this filter may need occasional cleaning. Note: A non-critical error in the product data file, such as error code 18 or 20 can be suggestive of such action. -

Appendix A Time Sync Implementation The product has a time-sync feature that allows users to synchronize the clock. This Appendix explains the data format options for the “time sync” and its implementation. Time Format Under the standard Modbus® register list, the timing is defined in Table A—1. Table A—1: Timing Group Data... - Page 29 A.2.2 UNIX Time Example For reference, the time on a device is reported in TransConnect as 12 Aug 2011 11:56:00 BST and the corresponding value in the registers mentioned above is 13146616. When testing, please check that you are reading registers 1197-1198 (assuming addresses start at 999 +1) and decoding an unsigned 32 bit big endian number.
