Diagnostics Alarms During normal operation when the TLS Console and monitored PMC and ISD System are functioning properly and no warning or alarm conditions exist, the "ALL FUNCTIONS NORMAL" message will appear in the system status area of the console display. Regardless of the TLS Console in use at this site, record the software part number as well as the software revision. There is an additional alarm, Battery Status (TLS-350 only), when wireless equipment is used in place of wires. ISD, PMC and Smart Sensor warnings and alarm are the same. If a warning or alarm condition occurs as a result of a failure in the wireless communication hardware the system displays the communication failure for the effected Smart Sensor. If more than one condition exists, the display will alternately flash the appropriate messages.The system automatically prints an alarm report showing the warning or alarm type, its location and the date and time the warning or alarm condition occurred. Any break in link between transmitter and sensor, or between TLS and TLS RF results in Communication Alarm.All other alarms related to individual sensor types, such as sensor fault alarm, are supported as they are with a wired system. When the Sensor Transmitter has determined the communication with the RF box has failed it will command the Vapor Valve to close.The valve will remain closed until an open command is sent (from the TLS) after communication is reestablished. Battery Diagnostics You can get the battery status from the TLS-350 (with software Version 30A or higher).The battery status is displayed for the wireless sensors, from the Smart Sensor Diagnostics (see Figure 23).The wireless sensors's battery status can also be printed from that screen. The battery status for the wireless sensors is reported as Full, Medium, Low or Replace. • Full: greater than or equal to 3.4 Volts • Medium Range: 3.2V to 3.4 Volts • Low range: 3.OV to 3.2V • Replace: Below 3.OV When the Smart Sensor battery reports a status 'Replace' continuously for 24 hours, a Smart Sensor warning will be posted on the TLS to alert the operator that the battery requires replacement.The warning will persist in the TLS until the battery reports 'Medium' or 'Full'.The alarm will clear at that time.This is a low priority TLS warning which will sound the beeper, flash the yellow warning light, post on the two line display, print on the printer and be recorded in the non-priority alarm history.The warning can be accessed remotely and be reported remotely similar to all TLS warnings and alarms.This warning will not appear in the ISD or PMC reports (only sensor failures are recorded in the ISD and PMC reports). WIRELESS SENSOR DIAGNOSTIC MENU (TLS-350 CONSOLES) The Battery Status for all wireless Smart Sensors will be displayed in the menu after the Serial Number (see Figure 23). 10-38 GARB Approved IOM 10-Veeder Root TLS RF Wireless Systems(W2)-Executive Order VR-202
