Operation <br /> Alarms <br /> OVERVIEW OF TLS CONSOLE INTERFACE <br /> The TLS console is continuously monitoring the vapor recovery system and ISD sensors for alarm conditions such <br /> as excessively high or low vapor collection, containment system vapor leakage and equipment problems. <br /> During normal operation when the TLS console and monitored EVR/ISD System is functioning properly and no <br /> alarm conditions exist, the "ALL FUNCTIONS NORMAL" message will appear in the system status (bottom) line <br /> of the console display, and the green Power light will be On (see Figure 17). <br /> MMM DD, YYYY HH:MM XM <br /> ALL FUNCTIONS NORMAL <br /> Liquid Crystal Display MODE Qz.

TLS Console Alarm Interface <br /> If an alarm condition occurs the system displays the condition type and its location. If more than one condition <br /> exists, the display will continuously cycle through the appropriate alarm messages. The system automatically prints <br /> an alarm report showing the alarm type, its location and the date and time the alarm condition occurred. <br /> Warning and alarm posting causes the TLS console-based system to activate warning or failure indicator lights, an <br /> audible alarm, and an automatic strip paper printout documenting the warning or alarm. Historical reports of <br /> warning and alarm events are available for up to one year. <br /> WARNING POSTING <br /> Displayed messages alert you to the source and type of alarm. Printed messages show the type and location of <br /> the alarm. In the Warning example in Figure 18, the display's second line and printed message indicates that the <br /> containment system's vapor leak rate has increased above the allowed standard generating a warning. <br /> 10-25 <br /> CARO Approved IOM 10 -Veeder Root IN Install,Setup,8 Operation Manual-Executive Order VR-202 <br />
