2 Overview This document provides procedures for troubleshooting a Metasys Building Automation System (BAS). This document can help qualified personnel effectively isolate a Metasys problem to a specific feature or hardware item. The troubleshooting charts list possible causes for symptoms exhibited at an Operator Workstation (OWS) or Personal Computer (PC). The charts are grouped by symptom categories: offline unreliable inaccurate readings feature anomalies control anomalies trunk statistics high error rate counts charts The error logs for the Network Control Module (NCM) and Operator Workstation contains Metasys error codes and messages. Examine the NCM Error Log and OWS Error Log periodically. These error logs can indicate any problems that are occurring, even though no outward symptoms may exist. For specific information on OWS/NCM warnings, see the Advanced Topics chapter in the DDL Programmer s Manual (LIT ). 2 Troubleshooting Guide Technical Bulletin

3 Troubleshooting Charts The most probable causes for a problem are listed at the top of a troubleshooting chart, while the less probable causes appear lower in the chart. The higher levels of the system appear on the left side of the chart. As the charts move from left to right, they involve the lower levels of the system. Using the Charts Locate the system s Symptom at the upper left of the Troubleshooting Chart. Proceed to Statement 1 (see Figure 1 for an example chart). If Statement 1 is False, proceed down the chart and investigate Possible Causes 1, 2, and 3. If Statement 1 is True, proceed to the right and investigate Possible Causes 4 and 5. If all of the possible causes are ruled out, proceed to Statement 2. In general, if a statement is True, proceed to the right; if a statement is False, proceed down the chart. Symptom Statement 1 Statement 2 False Possible Cause 1 Possible Cause 2 Possible Cause 3 True Possible Cause 4 Possible Cause 5 Figure 1: System Troubleshooting Chart Troubleshooting Guide Technical Bulletin 3

27 NC Task/Error Log The NC Task/Error Log is a record of runtime errors of the NCM. You can view the Error Log from the OWS. Its contents may seem indecipherable, but give a copy to the Johnson Controls support staff. They can interpret the log and use it to troubleshoot the Metasys Network. To view the NC Task/Error Log: 1. Go to the Network Map. 2. Select an NC to view. 3. On the Action menu, click Diagnostics. 4. Click the Task/Error Log option. The NC Task/Error Log appears. To print the screen, use the Print option in the Item menu. The NCSETUP for Windows tool also can display the NC Task/Error Log at the NCM. However, the error text is not available. Example What follows is an example of the NC Task/Error Log. The Error Log displays the date and time of the error, the Metasys error number, the error argument (Arg), the task ID (the software task that caused the error), and a brief explanation of the error number. For a list of error numbers and their respective error text, see the next section of this document. Arguments are task dependent. The task IDs and their descriptions are listed in the NCM Task IDs section of this document. Troubleshooting Guide Technical Bulletin 27
