OVERVIEW OF TLS CONSOLE INTERFACE
The TLS console is continuously monitoring the vapor recovery system and PMC sensors for alarm conditions.
During normal operation when the TLS console and monitored PMC equipment is functioning properly and no
alarm conditions exist, the "ALL FUNCTIONS NORMAL" message will appear in the system status (bottom) line
of the console display, and the green Power light will be On (see Figure 7).
Figure 7.
TLS console alarm interface
If an alarm condition occurs the system displays the condition type and its location. If more than one condition
exists, the display will continuously cycle through the appropriate alarm messages. The system automatically prints
an alarm report showing the alarm type, its location and the date and time the alarm condition occurred.
Warning and alarm posting causes the TLS console-based system to activate warning or failure indicator lights, an
audible alarm, and an automatic strip paper printout documenting the warning or alarm.
