Bul. 937C Universal Temperature Converter Installation Instructions Safety Notes The Universal Temperature Converter must only be operated by trained personnel in accordance with this handbook. Attention Warning Attention Attention The protection of operating personnel and of the system is only ensured if the devices are used in accordance with their intended purpose.
Bul. 937C Universal Temperature Converter Installation Instructions Overview The devices of the Bul. 937C IS Barriers, Isolators and Converters are used to transmit signals between field devices and the process control system or control. The Bulletin 937 devices are suitable for connection to field devices in the hazardous area. The field current circuits of these devices are intrinsically safe and are galvanically isolated from the not intrinsically safe circuits.
Bul. 937C Universal Temperature Converter Installation Instructions Mounting Attention The Universal Temperature Converter is constructed in protection class IP20 and must therefore be protected from undesirable environmental conditions (water, dust, small foreign objects). The Universal Temperature Converter can be mounted on a 35 mm top-hat rail corresponding to DIN EN 50022. The devices must be snapped onto the rail vertically, and never slanted or tipped to the side.
Bul. 937C Universal Temperature Converter Installation Instructions 118 115 111 20 Connection The slip-off terminals significantly simplify connection and construction of switching cabinets. They allow quick and errorfree exchange of the unit when service is needed. The terminals can be screwed on, are self-opening, and have generous connection room for a wire diameter of up to 2.5 mm² and coded plugs, so that leads cannot be confused.

Bul. 937C Universal Temperature Converter Installation Instructions If a current output is operated as a sink, the voltage across the terminals must be between 5 V and 30 V. An additional resistance is only required if the voltage is above 16.5 V. The resistance must be between (U - 16.5 V)/0.0215 A and (U - 5 V)/0.0215 A (see diagram). Example: U = 24 V (24 V - 16.5 V)/0.0215 A = 350 Ω (24 V - 5 V)/0.
Bul. 937C Universal Temperature Converter Installation Instructions If a current output is operated as a source, the load resistance must be between 0 Ω and 550 Ω (535 Ω if the output format is 4 mA to 20 mA unlimited).
Bul. 937C Universal Temperature Converter Installation Instructions Configuration tools The Bul 937CS-AITMP-DC1 Universal Temperature Converter is parameterised using an FDT configuration tool such as PACTwareTM. Installation and connection with the device Install the FDT software (ie PACTwareTM) on a PC. Connect the PC and the Bul 937CS-AITMP-DC1 using the 937A-USBA USB cable. This cable can be ordered as an accessory. Pressing the plug in by force may damage the end devices.
Bul. 937C Universal Temperature Converter Installation Instructions Communication driver In a PACTwareTM project, communication with a 937CS-AITMP-DC1 is only possible via the communication driver P2P USB FDT. If your project does not yet contain such a driver, please add it to the project from the device catalogue (see "PACTwa reTM process automation configuration tool" manual). The parameters of the communication DTM is the used PC interface and the number of retries.
Bul. 937C Universal Temperature Converter Installation Instructions Measured value If you have started the communication between PACTwareTM and device (e. g. via Device data → Establish connection), you can open the Measured value window via Device data → Measured value. It shows the following information on the outputs of the 937CS-AITMP-DC1 Universal Temperature Converter: • Measured values at the inputs as numerical values and bar graph, displayed in the selected units.
Bul. 937C Universal Temperature Converter Installation Instructions Simulation If you have started the communication between PACTwareTM and Bul. 937CS-AITMP-DC1 (e. g. via Device data → Establish connection), you can open the Simulation window via Device data → Simulation. The simulation interrupts the normal function of the device! Before starting the simulation, make sure that no dangerous condition in the plant will result. Warning The simulation mode is started with the check box Simulation Active.
Bul. 937C Universal Temperature Converter Installation Instructions Diagnosis If you have started the communication between PACTwareTM and Bul. 937CS-AITMP-DC1 (e. g. via Device data →Establish connection), you can open the Diagnosis window via Device data → Diagnosis. It shows the following information: Explanations: • Memory error: error in the memory of the Bul.

Bul. 937C Universal Temperature Converter Installation Instructions Editing device data Any change to device data will change the operation of the device! Before transferring new data into the device, make sure that no danger to the installation will result. Warning If you call the parameters for a Bul. 937CS-AITMP-DC1 in PACTwareTM (e. g. Device data → Parameters, a window with menus for parameterization appears, these manues will be described as follows.
Bul. 937C Universal Temperature Converter Installation Instructions Please specify the frequency of your supply network (50 Hz or 60 Hz) under Net frequency. This way you achieve the best possible suppression of influences of this net frequency on the Bul. 937CS-AITMP-DC1 Via Output Type the type of the analog output (current, voltage) can be preselected. This depends on the device which shall be parameterised. The information in menu Description can be edited as desired.
Bul. 937C Universal Temperature Converter Installation Instructions Menu Input The Input tab has the three subordinate tabs I/input, II/input and Extras. Menu Input 1 On the menu Input 1, you set the parameters for the input at the terminals 1 to 3.
Bul. 937C Universal Temperature Converter Installation Instructions The following parameters can be set: • Sensor (see Connection section): − Resistance temperature detector: Pt10GOST etc. − Thermocouple: TXK etc.
Bul. 937C Universal Temperature Converter Installation Instructions Behavior of the current output of the Bul. 937CS-AITMP-DC1 The linear behaviour outside the measurement range described in the following only results if temperature values ranging between the minimum value and the maximum value of the selected sensor correspond to the current values. If this is not the case, the output current jumps to the minimum or maximum specified value.
Bul. 937C Universal Temperature Converter Installation Instructions At this setting, the start value of the measurement range is converted to 4 mA and the end value to 20 mA. Intermediate values are converted proportionately. If the value falls below the start value, the output current decreases linearly to a minimum of 3.8 mA (-1.25 % of the measurement range). Further decreases cannot be evaluated (output 3.8 mA).
Bul. 937C Universal Temperature Converter Installation Instructions At this setting, the start value of the measurement range is converted to 0 mA and the end value to 20 mA. Intermediate values are converted proportionately. Values less than the start value cannot be evaluated (output 0 mA). If the value exceeds the end value, the output current increases linearly to a maximum of 20.5 mA (102.5 % of the measuring range). Further increases cannot be evaluated (output 20.5 mA).
