Figure 18. Log Graph Menu DOC. #TD-0465 10/20/06 Monitoring and Controlling the System 15
Like the Log Menu, the top half of this screen shows settings for several log parameters that were programmed in Novar s software. The first line of the display shows the data log s number and name. The second line shows the number of entries to be logged for each point and how often an entry is recorded in the log. When the log reaches the maximum number of entries, the oldest data is dropped and replaced with a new reading. The third line shows if the logging is to run continuously or to stop at a user-defined date and time. The fourth line shows if there is an offset time. The offset time changes the actual time data logs are recorded. This feature is used to synchronize the data log with the clock so entries are logged at desired intervals. The remainder of the screen provides a list of logs that the operator can select for display as a graph (Figure 19). Figure 19. Log in graph format (not interactive) The name of the executive module, the current time and date, and the name of the log appear at the top of the screen. It also shows the unit of measure along the side of the graph and the time the data was logged along the bottom. 16 Monitoring and Controlling the System DOC. #TD-0465 10/20/06
Interactive Graph NOTE! Historical logs cannot be viewed as a graph through the touchscreen or a Web browser. Selecting the Interactive Graph option in the Log Menu opens a screen displaying the log in interactive graph format (Figure 20). Figure 20. Log graph (Java enabled browser) The graph shows the logged values from the time the log started to the current time. Values are displayed along the left side of the graph. Dates and times are displayed along the bottom of the graph. The graph itself plots values at specific dates and times. The user can change the range of data displayed by clicking on the screen to move the data log entry pointer. As the pointer moves, the date, time, and values displayed below the graph change to show the values at that data log time and date. In the touchscreen, if the log is set up for 128 intervals, the entire log will be displayed on one screen; no scrolling will be required. If the log is set up for more than 128 intervals, the screen contains arrows and scroll bars that can be used to scroll to desired information. On the Web screen, the entire graph is displayed on one screen. DOC. #TD-0465 10/20/06 Monitoring and Controlling the System 17

Alarm Messages If a problem with a load is detected, the Lingo XE displays alarm messages on the monitoring display. The following table lists the possible Lingo XE alarm messages and provides a description of each. Some of the messages are general, but others are specific to certain load types. The LOAD TYPE column indicates whether the alarm message is load-specific or applies to all loads. ALARM COMM LOSS DIRTY FILTER AIR FLOW DRIFT ALARM PHASE LOSS CONFIR M STAT MAINT OVRRID SENSOR FAULT EMERG OVRRID DESCRIPTION The control module is not communicating with the Lingo XE. At the air filter, an insufficient air flow is being registered indicating a dirty filter. The filter switch has closed. The airflow input is active and the fan is enabled, but the switch does not detect air flow. All the outputs are forced off. If an airflow alarm appears at the top of the Load Monitoring screen, a Reset hyperlink will appear next to it. The hyperlink can be used to reset the alarm. The space temperature (heat or cool) is beyond and continuing to drift away from the setpoint. One of the three phases of alternating electrical current being supplied to the facility has been lost. Closed contacts at the Lingo XE s Phase Loss input have shut off the designated loads. A corresponding contact closure is not responding correctly to the on or off status of a load. The auto setting of one of an IOM s On-Off -Auto switches has been manually overridden to on or off. An input sensor has shorted, failed, or the reading is outside the defined sensor range. One of the conditions that has been defined in the software to activate an emergency and override a load s operation is occurring.
