8 2.4 Installation instructions ATEX / IECEx The installation, commissioning, maintenance and repair of devices in potentially explosive atmospheres must only be carried out by appropriately trained personnel. Works may be carried out only by persons, whose training has included instructions on different types of ignition protection types and installation techniques, concerned rules and regulations as well as general principles of zoning. The person must possess the relevant expertise for the type of works to be executed. When operating with combustible dusts, EN must be complied with. The safety instructions for electrical apparatus in potentially explosive areas must be complied with, in accordance with the directive 2014/34/EU (ATEX) and e.g. IEC (Installation of equipment in potentially explosive atmospheres). To ensure safe operation, the respectively applicable requirements must be met for the protection of workers Cable entries Devices with the "Ex d" type of protection supplied without cable glands For devices with the "Ex d - flameproof enclosure" type of protection supplied without cable glands, refer to the information in chapter "Flameproof enclosure - Zone 0 / 1" on page 12 and "Flameproof enclosure - Zone 1" on page 11. For information on the cable gland used, refer to the relevant data sheet and operating instructions. Devices with the "Ex d" type of protection with cable glands For devices with the "Ex d - flameproof enclosure" type of protection, a correspondingly certified cable entry is installed if the relevant selection is made for cable entry into the temperature transmitter TTFx00. This corresponds to the basic requirements of the guideline 2014/34/EU. Installation instructions The sealing rings of the cable glands harden at low temperatures. Before installation, bring the sealing rings to a temperature of at least 20 C for 24 hours. Before inserting the sealing rings and fixing them onto the cable gland, knead the rings to ensure they are soft and flexible. IP rating IP66 / 67 is only achieved by installing the black neoprene sealing ring between the cable gland and the housing and by observing the tightening torque of 3.6 Nm (Fig. 2, item 2). Cables must be protected against extreme mechanical loads (caused by tension, torsion, crushing, etc.). Even under operating conditions, it must be ensured that the cable entry remains hermetically sealed. The customer must provide a strain relief device for the cable. A B Ø C Fig. 1 : Stripping of connection cable A 40 mm B 12 mm C Ø 8.5 / 12 mm 1. Check that cable used is suitable (i.e., check the mechanical resilience, temperature range, creep resistance, resistance to chemicals, outside diameter, etc.). 2. Strip the cable in accordance with Fig Check the outer sleeve for damage and soiling. 4. Insert the cable in the cable gland. 1 2 A10229 Cable gland data 2 x M20 x 1.5 or 2 x 1/2 in. NPT Temperature range: C ( F) Cable outer diameter mm ( inch) Brass, nickel-plated The cable entry is only suitable for fixed installations and nonreinforced cables with round and smooth plastic sleeves and suitable outside diameter. The cables must be attached appropriately in order to prevent them being pulled out or twisted. The operating instructions supplied and approvals of the cable glands as well as all applicable requirements, e.g. in accordance with EN must be taken into account accordingly. Fig. 2 : Tighten the cable glands A Tighten the cable gland until the cable is firmly enclosed by the sealing ring (Fig. 2, item 1). Do not tighten more than 1.5--times of the specified torque on the cases (see assembly instructions)! Maintenance Check the cable glands during each maintenance session. If the cable is slack, retighten the cap(s) of the cable glands. If it is not possible to retighten them, the cable gland will need to be replaced. 8 OI/TTF300-EN Rev. F TTF300

9 M20 x 1.5 plastic cable gland for various types of protection The M20 x 1.5 plastic cable gland (supplied on an optional basis) has a limited temperature range. The permissible ambient temperature range of the cable gland is C ( F). When using the cable gland, make sure that the ambient temperature is within this range. The cable gland must be installed in the housing with a tightening torque of 3.8 Nm. On the cable side, when installing the connection of the cable gland and cable, check for integrity to ensure that the required IP rating is met Electrical connections Earthing If, for functional reasons, the intrinsically safe circuit needs to be earthed by means of a connection to the potential equalization, it may only be earthed at one point. Installation in a potentially explosive atmosphere Transmitters can be installed in all kinds of industrial sectors. Potentially explosive systems are divided into zones, meaning that a wide range of different instruments are also required. For this, pay attention to the country-specific guidelines and certificates! NOTICE Ex relevant specifications must be taken from the EC-type examination certificates and other relevant certificates that apply in each case. With transmitters for PROFIBUS PA and FOUNDATION Fieldbus H1 applications, FISCO interconnection methods can be used.

16 4 Function and System Design TTF300 digital transmitters are communication-ready devices with microprocessor-controlled electronics. With HART transmitters, an FSK signal is superimposed on the 4 20 ma output signal in accordance with the HART standard to facilitate bidirectional communication. With PROFIBUS PA transmitters, communication takes place in accordance with PROFIBUS MBP (IEC ), PROFIBUS PA profile With FF transmitters, communication takes place in accordance with FOUNDATION Fieldbus H1 (IEC ), ITK Version 5.x. The transmitters can be configured, polled, and tested using a DTM or an EDD A10091 Fig Supply voltage cable 2 Transmitter TTF300 3 Temperature sensor 4 Process pipe 5 Sensor connecting cable 4.1 Input functionality Sensor Redundancy To enhance system availability, the TTF300 has two sensor inputs. The second sensor input can be used redundantly for both resistance thermometers (2 x three-wire circuit or 2 x two-wire circuit) and thermocouples, or for a mixture of the two. Sensor redundancy (or sensor backup) always involves measuring the temperature of the two sensors and calculating the mean value on the basis of this. This value is provided at the output of the transmitter. Should a sensor fail, the temperature measurement for the sensor that remains in operation is provided at the output of the transmitter. A relevant diagnostic message is provided via the EDD or DTM, or shown on the display. The measured value remains available and maintenance measures can be taken at the same time Sensor drift monitoring When two sensors are connected, sensor drift monitoring can be activated via the EDD or DTM. The sensor drift monitoring can be activated for the following sensor types: 2 x resistance thermometer (RTD), two-wire circuit 2 x resistance thermometer (RTD), three-wire circuit 2 x resistor (potentiometer), two-wire circuit 2 x resistor (potentiometer), three-wire circuit 2 x thermocouple 2 x voltage 1 x resistance thermometer (RTD), two-wire circuit, and 1 x thermocouple 1 x resistance thermometer (RTD), three-wire circuit, and 1 x thermocouple 1 x resistance thermometer (RTD), four-wire circuit, and 1 x thermocouple To activate sensor drift monitoring, the transmitter must first be configured for the sensor types referred to above. Following this, the maximum permissible sensor deviation must be configured, e.g., 1 K. Since sensor response times may differ slightly, it is then necessary to configure a limit time period during which the sensor deviation has to constantly exceed the maximum set. If the transmitter records a larger sensor deviation during the defined time period, a HART, EDD, and DTM diagnostic notification - "Maintenance required" - is generated according to NE 107. At the same time, diagnostic information is shown on the LCD display. If drift monitoring is used for the same types of sensor (2 x Pt100 or 2 x thermocouple), the mean value calculated from the two sensors is mapped to the transmitter's output signal as a process variable in redundancy mode. If a thermocouple is used for Pt100 drift monitoring, the Pt100 sensor (see chapter "Electrical connections" on page 9) must be connected to channel 1 and the thermocouple to channel 2. The measured value from channel 1 (Pt100) is mapped to the transmitter output as a process variable. NOTICE Before configuring the maximum permissible sensor deviation for drift monitoring, sensor adjustment with respect to the sensor channel 1 value must be carried out with the help of the TTF300 DTM. 16 OI/TTF300-EN Rev.

17 4.1.3 Sensor error adjustment according to Callendar- Van Dusen Under normal circumstances, the standard Pt100 characteristic curve is used for resistance thermometer measurement. However, recent advances in technology now mean that maximum measuring accuracy can be achieved where necessary by carrying out individual sensor error adjustment. Sensor characteristic curves are optimized by using a Pt100 polynomial in accordance with IST-90 / IEC 751, and EN 60150, and by applying A, B, C, or Callendar-Van Dusen coefficients. The DTM or EDD can be used to set and store these sensor coefficients (Callendar-Van Dusen) in the transmitter as a CVD characteristic curve. Up to five different CVD characteristic curves can be stored for HART and PROFIBUS PA, and up to two can be stored for FOUNDATION Fieldbus m l k j A11236 Fig. 14: HART name plate (example) Fig. 15: PROFIBUS PA name plate (example) A Product identification 5.1 Name plate NOTE Products that are marked with this symbol may not be disposed of through municipal garbage collection points.

20 Change from two to one column 7.3 Electrical connections DANGER Improper installation and commissioning of the device carries a risk of explosion. For use in potentially explosive atmospheres, observe the information in chapter "Use in potentially explosive atmospheres according to ATEX and IECEx" on page 6 and "Use in potentially explosive atmospheres in accordance with FM and CSA" on page 13! Observe the following information: The electrical connection may only be made by authorized specialist personnel and in accordance with the electrical circuit diagrams. The relevant regulations must be observed during electrical installation. The electrical connection information in the manual must be observed; otherwise, the type of electrical protection may be adversely affected. Safe isolation of electrical circuits which are dangerous if touched is only guaranteed if the connected devices satisfy the requirements of DIN EN (VDE 0140 Part 1) (basic requirements for safe isolation). To ensure safe isolation, install supply lines so that they are separate from electrical circuits which are dangerous if touched, or implement additional isolation measures for them. Connections must only be established in a dead-voltage state. The transmitter has no switch-off elements. Therefore, overcurrent protective devices, lightning protection, or voltage disconnection options must be provided at the plant. The power supply and signal are routed in the same line and must be implemented as a SELV or PELV circuit in accordance with the relevant standard (standard version). For the Ex version, the guidelines stipulated by the Ex standard must to be adhered to.
