START-Up AND SySTEM TESTING
power up the system.
After connections are complete, supply power to the unit. The unit will go through a series of self-
tests, and then display the system status. If the sensing circuit is complete and free of leaks or
other problems, only the green Monitoring LED will illuminate, and the LCD display will appear
similar to that shown at right:
If this is not the case, you can find additional information in the TTDM-128 Operation and
Maintenance Manual (H56853) supplied with the module.
Commissioning.
Your system should be commissioned by an authorized TraceTek representative including creation
of a System Map. The System Map is a crucial part of a TraceTek locating system. The System
Map is normally completed at the time the leak detection system is commissioned. The System
Map is defined for each SIM sensor circuit, typically an as-built drawing of the sensor cable/
component layout with reference to readily identifiable landmarks, preferably with actual distance
measurements every 5m (16ft) throughout the system. The System Map should be constructed
with simulated leak events at convenient locations along the leak detection circuit. The reported
leak distance (from TTDM-128) is recorded on the System Map for every tested location. The
TTDM-128 will give the point along the sensing cable at which liquid has been detected; the map is
essential to show its physical location.
IMpORTANT: Store hardware and documentation supplied with the TTDM-128 in a secure place for
later use (commissioning, connecting interfaces, operating). If the equipment is used in a manner
not specified by the manufacturer, the protection provided by the equipment may be impaired.
IMpORTANT: Before creating a leak alarm for System Mapping purposes, the sensing cable
parameters RG Resistance and YB Resistance should be stable and equal +/- 2%, and cable
parameter Sense Res should be greater than 10,000 kohms.
