Tagging
Alphanumeric Region Tagging for TraceTek TTDM-PLUS / TTDM -128 / TTSIM
leak detection system
Here are a few things to consider about the "5 region" capability.
What is a region: This is defined as a section of sensing
cable or a number of probes within a circuit, either on
a TTDM panel or a SIM module. It may cover a single
area or room; you can therefore assign this room as a region
and give the area and name that will assist in the location
of a leak.
From Version 2.01e the system has the increased capability
of 10 regions and the ability to assigned any region to
individual volt free relay contacts by using the TT-NRM
(Network Relay Module)
The TTDM software from version 1.05o, offers the facility
to define "Alphanumeric Region Tagging". For
single stand alone panels and TTSIM network systems.
The "regions" are defined by a "look up
table" that is entered into the TTDM menu for each
TTDM /SIM channel. The user can enter a low value, a high
value, and a 14 character message for each region. If a
leak is detected, the software in the TTDM uses the
leak location value and compares it with the low and high
limits for any region definitions that have been entered
for that TTDM / SIM channel. The first match in the look
up table causes that 14 character message to be substituted
for the normal SIM ID on the front panel display. Additional
as with all TraceTek pin point location systems the panel
will also display the leak location in meters from the
beginning of the circuit.
For example if you have a 250 meter circuit on SIM channel
3. You might enter the SIM ID of: NORTH CORE. You could
then enter:
LOW |
HIGH |

Under
normal conditions the display would say:
If
a leak is detected at 125 meters the display would say:
Since
the latest versions of software release (version 2.01e),
the TTDM now has the capacity to manage 128
SIM’s. The total number of stored messages can be
quite large (1280 region messages and 128 normal SIM ID
messages).
The alphanumeric indexing is simply entered by the user
or installation engineer using the front panel keypad on
the TTDM panel. Raychem is developing a Windows application
that will let you use a PC keyboard to make this set-up
task quicker.
To provide accurate location between "regions" a
branch connector or weighted a length between regions to
increase the distance separation is recommended to assure
an accurate region message.
