2 DEVICE DESCRIPTION |
TT 51 SERIES |
|
2.1 General description
The TT 51 transmitters are intelligent 2-wire universal transmitters for measurement with up to two user programmable channels in single, differential, average, minimum or maximum mode.
The transmitters are intended for:
•Temperature measurements with single or dual resistance thermometers
•Temperature measurements with single or dual thermocouples
•Temperature measurements with one resistance thermometers and one thermocouple
•Temperature difference measurements with resistance thermometers
•Measurements with potentiometers
•Voltage measurements in a range -10…1000 mV
To increase reliability and stability of the system the transmitters have dual sensor inputs. The dual sensor inputs enable new safety features such as sensor redundancy and sensor drift monitoring.
The TT 51 C are designed for installation in a B connection head according to DIN 43729 or larger.
The TT 51 R are designed for installation on a rail according to DIN 50022.
INFORMATION!
The transmitters are assessed by exida according to IEC 61508-2 for use in SIL 2 rated Safety Instrumented Systems (SIS). For safety instructions see the separate safety manual.
Following Ex approvals for the transmitter are available:
•Standard version: without any Ex approval
•Non-incendive version: TT 51 C / TT 51 R for use in areas with potentially explosive atmospheres (zone 2)
•Intrinsically safe version: TT 51 C for use in areas with potentially explosive atmospheres (zone 0, 1 and 2)
•Intrinsically safe version: TT 51 R for use in areas with potentially explosive atmospheres (zone 1 and 2)
The 2-wire universal transmitters are HART® 5 and 6-compatible. Configuration of the transmitter is possible with:
•HART® 5 and 6 protocol via 4…20 mA output circuit
•HART® 5 and 6 hand held terminal
•The graphic user interface DTM
•The third part PC software with a FSK modem for HART® 5 and 6 communication

3.1 Notes on installation
INFORMATION!
Inspect the cartons carefully for damage or signs of rough handling. Report damage to the carrier and to the local office of the manufacturer.
INFORMATION!
Check the packing list to check if you received completely all that you ordered.
INFORMATION!
Look at the device nameplate to ensure that the device is delivered according to your order. Check for the correct supply voltage printed on the nameplate.
3.2 In-head transmitter
These transmitters are intended for installation in DIN B connection heads or larger. The large Ø7 mm / 0.28" center hole facilitates the electrical connection of the measurement sensor and the installation. For detailed information refer to the chapter "Dimensions and weights".

DANGER!
The TT 51 C transmitter is optionally available in a non-incendive version (zone 2) and in an intrinsically safe version (zone 0, 1 and 2) for installation in potentially explosive atmospheres. The intrinsically safe version must be supplied by an intrinsically safe power supply unit or Zener barrier placed outside of the potentially explosive zone.
The Ex transmitter must be installed in a housing with the protection rating IP20 or better according to EN 60529 / IEC 60529.

3 INSTALLATION |
TT 51 SERIES |
|
INFORMATION!
The TT 51 C transmitter has been developed for an ambient temperature of
-40...+85°C / -40...+185°F. Please also note that the ambient temperature is also dependent on the temperature category. For detailed information refer to Ex data of the ambient temperature. The process temperature is also transferred to the transmitter housing via the protective tube. If the process temperature is close to or exceeds the maximum specified process temperature, then the temperature in the transmitter housing can rise above the maximum permissible ambient temperature. Always check that the ambient temperature where the transmitter is installed is always within the permissible range. One way to decrease heat transfer via the protective tube is to make the protective tube longer or in general to install the transmitter farther away from the heat source. The same safety measures can be taken if the temperature is below the specified minimum temperature.
3.3 Rail-mount transmitter
These transmitters are intended for installation on a rail according to DIN 50022.
Figure 3-2: Rail installation
1 Fix the upper part of the transmitter onto the rail.
2Press the lower part of the transmitter against the rail.
3To remove the transmitter, use a screwdriver to bend the locking device using a small screwdriver. Carefully pull the transmitter in the forward direction.

4.1 Safety instructions
DANGER!
All work on the electrical connections may only be carried out with the power disconnected. Take note of the voltage data on the nameplate!
DANGER!
Observe the national regulations for electrical installations!
DANGER!
The transmitter is protected against polarity reversal. No damage will occur to the device if the polarity of the supply voltage is switched. The output will then indicate 0 mA.
DANGER!
The TT 51 C / TT 51 R are optionally available in a non-incendive version for use in potentially explosive atmosphere zone 2. For zone 2 applications a class 2 power supply placed in safe area is needed. In other potentially explosive areas, the intrinsically safe versions must be used. The TT 51 C (intrinsically safe) can be installed in potentially hazardous area zone 0, 1 and 2. The TT 51 R (intrinsically safe) can be installed in potentially hazardous area zone 1 and 2 and the input may be connected to zone 0.
The intrinsically safe versions must be supplied by an intrinsically safe power supply unit or Zener barrier placed outside of the potentially explosive zone.
WARNING!
Observe without fail the local occupational health and safety regulations. Any work done on the electrical components of the measuring device may only be carried out by properly trained specialists.
INFORMATION!
Look at the device nameplate to ensure that the device is delivered according to your order. Check for the correct supply voltage printed on the nameplate.
4.2 Electrical connections of in-head transmitter
The input and output signals and the power supply must be connected in accordance with the following illustrations. The transmitter is easy to install with the connection head installation kit. To avoid measuring errors, all cables must be connected properly and the screws tightened correctly.
