Section 1 INSTALLATION General The overall accuracy of temperature and other parameters depends on several variables. Even considering the TT383 excellent performance, a proper installation is essential in order to maximize it. Among all factors which may affect transmitter accuracy, environmental conditions are the most difficult to control. There are, however, several ways of reducing the effects of temperature, humidity and vibration.
TT383 – Operation and Maintenance Instruction Manual Figure 1.2 – Dimensional Drawing Mounting: Attach the top rail and press to lock the module. See Figure 1.3. Figure 1.3 – TT383 Assembly in DIN Rail To remove the TT383 from the rack, press the TT383 upwards with its upper part bent outside the rack. See Figure 1.4. 1.
Installation Figure 1.4 –TT383 Disassembling the DIN Rail Network Wiring Connections are made via the screws on the front of the equipment. Figure 1.5 – Sensors and Supply Connections The wiring block has screws that can receive fork type terminals. WARNING Do not connect the Fieldbus network wires to the sensor terminals (Terminals 1, 2 and 3). TT383 uses the 31.25-kbit/s voltage mode option for the physical signaling. All other devices on the same bus must use the same signaling.
TT383 – Operation and Maintenance Instruction Manual Use of twisted pair cables is recommended. It is also recommended to ground shield of shielded cables at one end only. The non-grounded end must be carefully isolated. NOTE Please refer to the Profibus General Manual for more details. Sensor Wiring TT383 accepts one sensor for each channel. In accordance with connection and sensor types, the terminal blocks shall be wired as shown on the Figure 1.5. NOTE All sensors must be isolated of the process.

TT383 – Operation and Maintenance Instruction Manual Intrinsic Safety Barrier When the Fieldbus is in an area requiring intrinsic safety, a barrier must be inserted on the trunk between the power supply and the DP/PA coupler, when it is Non-Ex type. The use of DF47 is recommended. Learn more in http://www.smar.com/products/df47-12.asp. Jumper Configuration In order to work properly, the jumpers J1 and W1 located in the TT383 main board must be correctly configured (See Table 1.1).
Installation Installation in Hazardous Areas WARNING Explosions could result in death or serious injury, besides financial damage. Installation of this transmitter in explosive areas must be carried out in accordance with the local standards and the protection type adopted .Before continuing the installation make sure the certificate parameters are in accordance with the classified area where the equipment will be installed.

Section 2 OPERATION The TT383 accepts signals from mV generators, such as thermocouples, or resistive sensors, as RTDs. To make this possible, the signal must be within the configured input range. For mV, the range is from -50 to 500 mV, and for resistance, from 0 to 2000 Ohms. Functional Description - Hardware The function of each block is described below. Figure 2.
TT383 – Operation and Maintenance Instruction Manual Power Supply Takes power of the loop-line to power the transmitter circuitry. Power Isolation Just like the signals to and from the input section, the power to the input section must be isolated. Isolation is achieved by converting the DC supply into a high frequency AC supply and galvanically separating it using a transformer. Temperature Sensors Some basic concepts about temperature sensors are presented below.
Operation The TT383 allows a 2-wire connection that may cause measuring errors, depending on the length of connection wires and on the temperature to which they are exposed. (see Figure 2.3). In a 2-wire connection, the voltage V2 is proportional to the RTD resistance plus the resistance of the wires. V2 = [RTD + 2 x R] x I TRANSMITTER R 2,1 V2 I RTD R 3,4 Figure 2.

Section 3 CONFIGURATION This section describes the TT383 blocks. They follow the Profibus PA specifications, but concerning the transducer blocks, the input transducer block and display, they have some special features. The 303 Smar family is integrated in Profibus View, from Smar and in the Simatic PDM, from Siemens. It is possible to integrate any Smar device in Profibus with any configuration tool for Profibus PA devices.

TT383 – Operation and Maintenance Instruction Manual TT383 - Cyclic Configuration The PROFIBUS-DP and PROFIBUS-PA protocols have protections against communication failures between the slave device and the network master. For example, during initialization, these protections are used to check possible errors. After powering up the field device (slave), it is possible to cyclically exchange information with the class 1 master, if the parameterization for the slave is correct.
Configuration The device was created as TT383. Here, you can see all blocks instantiated. As you can see the Transducer and Display are treated as special type of Function Blocks, called Transducer Blocks. Figure 3.2 – Profibus View – Function and Transducers Block Figure 3.3 – PDM Simatic - Function and Transducers Blocks 3.
TT383 – Operation and Maintenance Instruction Manual Use this menu: - To change the device address; - To make the up/download of parameters; - To configure the Transducer Blocks, Analog Blocks and Display Block; - To calibrate the transmitter; - To make the reset by software, to protect the device against writing and to simulate the value from transducer block to analog block; - To save and restore data calibration.
Configuration Figure 3.5 – Profibus View - Transducer Advanced Settings The user can configure the Transducer Block, according to the selected Measurement Type (when you have selected "Process Temperature", it means that you will have eight sensors, eight transducer blocks and eight analog input blocks). Please, select the parameters according to your application. It is possible to configure connection and sensor type by means of parameters SENSOR_TYPE and SENSOR_CONNECTION.
TT383 – Operation and Maintenance Instruction Manual Setting the TT383 Address The address configuration can be done in two ways. The first is via configurator and the second via hardware. The key for address configuration is located under the cover and on the front side of the equipment identification label. Possible addressing is from 3 (000.0011) to 126 (0111.1111). The key has eight positions. Each position represents one bit in binary notation.
Configuration Differential – Transducer output is the difference between the readout of sensor 1 and the readout of sensor 2 (other channel). Backup - If the first sensor opens, the second sensor (other channel) will supply the signal to the transducer. Process Temperature – The readout is only in one channel.

Configuration Figure 3.11 – PDM Simatic - Upper Calibration Procedure NOTE Every time the sensor is changed, TRIM values are reset. How to Configure the Analog Input Block The Analog Input block takes the input data from the Transducer block, selected by channel number, and makes it available to other function blocks at its output. The transducer block provides the input unit of the Analog Input, and when the unit is changed in the transducer, the PV_SCALE unit is changed too.

Section 4 MAINTENANCE PROCEDURES General SMAR TT383 transmitters are extensively tested and inspected before delivery to the end user. Nevertheless, during their design and development, consideration was given to the possibility of repairs being made by the end user, if necessary. In general, it is recommended that end users do not try to repair printed circuit boards. Spare circuit boards may be ordered from SMAR whenever necessary.
