  • Page 36: Service Events

    Service Events INTRODUCTION A TraceTek sensing circuit consists of two electrical loops. The SIM module constantly monitors for current passing between loops. When the system is normal, there is no current passing between the loops. When there is a leak on the system, the maximum current flows. If, however, a SIM detects a lower but significant level of current flow between the loops, the TTDM will signal a Service Alarm.

  • Page 37: Fault Events

    TTDM-128 User Manual TO CLEAR THE CABLE Investigate the cause of the alarm and conduct cleanup or maintenance accordingly. HINT: If material causing a service alarm is spread throughout the system, it is often useful to subdivide the system; see INVESTIGATING LEAKS AND FAULTS on page 42 for further information.

  • Page 38: Multiple Events

    Multiple Events SIMULTANEOUS EVENTS ON DIFFERENT SIM CHANNELS The TTDM-128 is capable of monitoring many sensing circuits. Each SIM operates independently of other SIMs in the leak detection network. The TTDM-128 tracks information for all SIM channels and is capable of handling multiple events that occur in the same time frame.
  • Page 39 TTDM-128 User Manual Use the Events History to track the events between the “first leak” and the “most recent event.” See “The Events History Log” section on page 27. ADDITIONAL LEAK If liquid contacts sensing cable at a significant distance from the initial leak, the module will re-alarm however it will indicate that this realarm leak distance could indicate a new leak rather than a growing leak.

    TTDM-128 User Manual Maintenance CLEANING THE MODULE To clean the outside surface, use a damp cloth or sponge. Do not use solvents or abrasive cleaners and do not open the enclosure while it is wet (it is an electrical device). FUSE REPLACEMENT The fuse on the power supply board of the TTDM-128 and TTSIM units is a 200-mA, 250- V, quick-acting microfuse.
  • Page 42 INVESTIGATING LEAKS AND FAULTS Alarm and locating module If the location of a leak is not apparent, it is often useful to subdivide the leak detection circuit. To accomplish this, it is best to have a TraceTek Portable Test Box (PTB) or extra Sensor Interface Module, and an extra Modular End Termination.
