Operation 6.
Operation 6.5 Local operation See also Fault current (Page 118) Setting the current limits (Page 119) 6.5 Local operation 6.5.1 Local control elements Introduction The transmitter can be operated on-site using the keys. Selectable modes can be used to choose and execute the functions described in the table. The number of available functions is limited if the device does not have a display.
Operation 6.5 Local operation Operating functions Note Zero point calibration For absolute pressure transmitters, the start of scale value is at vacuum. A zero point calibration with transmitters which do not measure absolute pressure leads to faulty settings. Table 6-4 Operating functions using keys Function Mode Key function [M] [↑] Display, explanations [↓] [↑] and [↓] Measured value The modes are select ed here.
Operation 6.5 Local operation Function Key lock or function lock Characteristic curve1) Mode Key function [M] [↑] 10 Switch between the five functions 11 Display, explanations [↓] Switch between the four functions Smaller [↑] and [↓] – linear Application point of 12 the square root extracting characteristic curve1) Greater Measured value display 13 Select from three options.
Operation 6.5 Local operation Procedure In the default setting, the device is in the measured value display. To adjust the operating functions, proceed as follows: 1. Loosen both the screws of the keyboard cover and lift it upwards. 2. Keep pressing the [M] button until the desired mode is displayed. 3. Keep pressing the [↑] or [↓] button until the desired value is displayed. 4. Press the [M] button. Now you have saved the values and the device goes to the next mode. 5.
Operation 6.5 Local operation Depending on the series and measuring range, a maximum downscaling of 1:100 can be achieved (measuring span ratio = r, turn down). The correlation between the measured pressure and the output current generated is linear. The square root extracting characteristic curve for differential pressure transmitters is an exception. Calculate the output current using the following formula.
Operation 6.5 Local operation C 14 bar process pressure is created. Use the [M] button to set the transmitter to mode 3. To set the full scale value, press the [↑] and [↓] buttons simultaneously for 2 seconds. If there is 14 bar input pressure, the transmitter produces an output current of 20 mA. D The output current can be calculated for any input pressure using the "current calculation formula for setting".
Operation 6.
Operation 6.5 Local operation 6.5.3.2 Setting/adjusting the start of scale value NOTICE Inadvertent adjustment of parameters on devices without display or without visible display Key lock is canceled if you press the [M] key for longer than 5 seconds, see chapter "Releasing key lock or function lock (Page 91)". In the case of a device without display or without a visible display, you could inadvertently change parameters. ● Always press the [M] key for less than 5 seconds.
Operation 6.5 Local operation Setting the start-of-scale value without a display You have a device with a cover that does not have an inspection window and you wish to set the start of scale value. To set the output current of the start of scale value to 4 mA, proceed as follows: 1. Create the reference pressure. 2. Press the [↑] and [↓] buttons simultaneously. The device has set the start of scale value to 4 mA. 3. When you release the buttons, the device saves the adjusted value automatically.
Operation 6.5 Local operation 3. Set the full scale value to 20 mA. 4. Save with the [M] button. Adjusting full scale value If you do not set the output current but constantly adjust it, you need to calculate the currents to be adjusted mathematically. To the adjust the output current of the full scale value, proceed as follows: 1. Create the reference pressure. 2. Set mode 3. 3. Adjust the output current of the full scale value to the calculated value. 4. Save with the [M] button.
Operation 6.5 Local operation 6.5.4 Setting/adjusting electrical damping Difference between setting and adjusting You can set or adjust the time constant of electrical damping using the buttons. Setting means that the time constant is automatically set to 0 seconds. Adjusting means that the time constant is adjusted between 0 and 100 seconds using the steps of 0.1 seconds. This electrical damping also has an effect on the built-in basic damping of the device.
Operation 6.5 Local operation 6.5.5 Blind start of scale value/full scale value 6.5.5.1 Difference between setting/adjusting and blind setting/adjusting Differences In contrast to setting/adjusting with a reference pressure, you do not need a reference pressure for blind setting/adjusting. You can adjust a value in the physical variable "pressure" without a reference pressure, and an output current with a reference pressure. Blind adjusting First select the desired physical unit.
Operation 6.5 Local operation Explanations for the blind adjusting example A The measuring range is from 0 to 16 bar. You are changing the start of scale value from 0 to 2 bar and the full scale value from 16 to 14 bar. The measuring span is then 12 bar. In this example you create no pressure. B Use the [M] button to switch the transmitter to mode 5. To adjust the start of scale value to 2 bar, press one of the [↑] or [↓] buttons.
Operation 6.5 Local operation Condition You are familiar with the correct operation of the transmitter and the associated safety notes. You have not created any reference pressure and have selected a pressure unit. Procedure To the set the start of scale value blindly, proceed as follows: 1. Set mode 5. 2. Press the [↑] and [↓] buttons simultaneously for 2 seconds. 6.5.5.3 Blind setting of full scale value Introduction Blind setting resets the full scale value to the upper sensor limit.
Operation 6.5 Local operation 6.5.5.4 Blind adjusting of the start of scale value Introduction In the case of blind adjustment, adjust the pressure value of the start of scale value continuously and without a reference pressure. Note Changes in modes 5 and 6 have an exclusive effect on pressure scaling. This does not affect the scaling for level or customized characteristic curve. Therefore, only measured pressure values and pressure units are displayed in these modes.
Operation 6.5 Local operation Condition You are familiar with the correct operation of the transmitter and the associated safety notes. You have not created any reference pressure and have selected a pressure unit. Procedure To the adjust the pressure value of the full scale value blindly, proceed as follows: 1. Set mode 6. 2. Adjust the pressure value of the full scale value. 3. Save with the [M] button. 6.5.6 Trimming the zero point Introduction The zero point is calibrated in mode 7.
Operation 6.5 Local operation 1. Create the reference pressure. 2. Set mode 7. 3. Set the reference pressure on the display. 4. Save using the [M] key. 6.5.7 Current transmitter Introduction In mode 8, switch the pressure transmitter into the constant current operation. You can connect an external current transmitter in the constant current operation. The current then no longer corresponds to the process variable. The following output current can be adjusted irrespective of the input pressure: ● 3.
Operation 6.5 Local operation 6.5.8 Output current in case of fault Introduction When a fault occurs, the upper fault current is displayed in the basic setting. In mode 9, you can choose between the output of the upper and lower fault current. The standard values 3.6 mA and 22.8 mA are set. The standard values of the upper and lower fault current can be changed via HART communication. Condition You are familiar with the correct operation of the transmitter and the associated safety notes.
Operation 6.5 Local operation 6.5.9 buttons and function lock Introduction In mode 10, you can disable the functions that can be executed using buttons. Application example for a lock is e.g. safeguarding the saved parameters. Lock options You have the following lock options on the pressure transmitter: Table 6-5 Meaning of lock modes Lock mode Meaning 0 The device can be operated by means of the keys and HART communication. LA Keys on the transmitter are locked.

Operating functions through HART 7.1 7 Operating functions through HART communication Condition You can operate the transmitter through HART communication. The following is required for this purpose: ● A HART communicator or PC software such as SIMATIC PDM. ● A HART modem to connect a PC with the transmitter or a lead to connect a HART communicator with the transmitter. Introduction The full functionality of the transmitter is available via HART communication.
Operating functions through HART 7.3 Selecting the measuring modes 7.2 Process tag data You can store your process tag data in user definable fields.
Operating functions through HART 7.3 Selecting the measuring modes The following device variables are activated only when the allocated measuring mode is activated and parameterized simultaneously: ● "Level", "Volume" and "Mass" are allocated to the "Level" measuring mode. ● "Volumetric flow" and "Mass flow rate" are classified as "Flow rate" measuring mode. ● "User" is allocated to the "User" measuring mode. The inactive device variables have the CONSTANT status. 7.3.
Operating functions through HART 7.3 Selecting the measuring modes four variables, all other device variables are marked as inactive and have the CONSTANT status. These four variables are mapped with dynamic variables PV, SV, TV and QV by default. Switching an inactive device variable to the primary variable (PV) generates an error message since the variable currently does not have a valid measured value. This message is displayed in SIMATIC PDM or the HART communicator.
Operating functions through HART 7.3 Selecting the measuring modes In the device, the characteristic curve vertices are only provided once in the EEPROM. Therefore, if the measuring mode is changed, you will usually need to adjust the characteristic curve accordingly. The characteristic curve function expects at least two and at the most 30 characteristic curve vertices as input parameters. Characteristic curve vertices are entered in pairs of values x %;y %.
Operating functions through HART 7.3 Selecting the measuring modes with appropriate parameters. Only then will you be given a meaningful measured value for the three device variables.
Operating functions through HART 7.
Operating functions through HART 7.3 Selecting the measuring modes 7.3.7 Measuring mode "Flow rate" Description When you activate the "Flow rate" measuring mode, only two other device variables are active: volumetric flow and mass flow rate. If another block was active earlier, the corresponding device variables remain inactive and have the "CONSTANT" status. The "Flow rate" block here represents a series of permanently interconnected functions which you need to configure with appropriate parameters.

Operating functions through HART 7.21 Diagnostic functions When the warning/alarm limit has been reached, the following applies: 1. "Alarm/Acknowledge the request" resets the request / alarm message, but allows the timer to continue to run. In this state, a new alarm or warning is not possible since the time limits have already been exceeded. 2. "Reset timer" resets the request / alarm message, also resets the timer. It acknowledges the interrupt or warning at the same time.
Operating functions through HART 7.21 Diagnostic functions 7.21.5 Limit modules Introduction The diagnostic functions of this device give you an option to monitor the measured values in programmable limits. If the limits are not adhered to, the device sends a warning through HART communication or notifies a higher-level instance about an analog fault current. Monitoring of current saturation You can monitor the current output in the saturation range using a simple limit module.
Operating functions through HART 7.21 Diagnostic functions Example 1: the response time starts at t1. At t1, current reaches the configured saturation limit of 20.5 mA for the first time. At t2, the response time ends. The stop time begins and the interrupt is triggered. Time t3 is the configured end of the stop time. At t3, the interrupt is immediately revoked even if the current then drops below the saturation limit again.
Operating functions through HART 7.22 Simulation 7.22 Simulation 7.22.1 Overview of simulation Description With the "Simulation" diagnostic function, you can receive and process simulated measurement data onsite or in the control room without having process pressure or a temperature value. This allows you to run individual process sequences in the "cold" state and thus simulate process states.
Operating functions through HART 7.23 Limit monitor 7.22.2 Simulation as fixed value Description Taking the physical unit into account you can set a fixed simulation value for all three possible simulation paths. You can simulate the pressure value and both temperature values simultaneously. While pressure simulation is activated, the transmitter will not react to changes in the process pressure. The output value for the current adjusts itself in accordance with the preset pressure value.
Operating functions through HART 7.23 Limit monitor Hysteresis Operating point for chatter suppression in the case of small pressure changes. Response time The time which must pass after the limit is violated before this violation is registered. Stop time The time for which a limit interrupt or warning will always be sustained even when the event which triggered it is no longer present.
Operating functions through HART 7.23 Limit monitor Reset event counter upper limit Here you can reset the upper limit counter to zero. A new event is not possible until the counter has been reset. Reset event counter lower limit Here you can reset the lower limit counter to zero. A new event is not possible until the counter has been reset. Warning/interrupt acknowledgement Here you can acknowledge each warning or interrupt separately.
8 Functional safety 8.1 General safety instructions 8.1.1 Safety-instrumented system This chapter describes the functional safety in general and not specific to a device. The devices in the examples are selected as representative examples. The device-specific information follows in the next chapter. Description The combination of transmitter, automation system and final controlling element forms a safetyinstrumented system that performs a safety function.
Functional safety 8.1 General safety instructions Function principle of multi-channel operation Transmitter 6KXWGRZQ VLJQDO 0HDVXUHG YDOXH Figure 8-2 Final controlling elements Automation system Safety-instrumented system (SIL3) The transmitter generates process-related measured values that are transferred to the automation system. The automation system monitors these measured values.
Functional safety 8.1 General safety instructions The "average probability of dangerous failures of the entire safety-instrumented system" (PFDAVG) is normally split between the three sub-systems in the following figure.
Functional safety 8.2 Device-specific safety information for single-channel operation (SIL 2) 8.2 Device-specific safety information for single-channel operation (SIL 2) 8.2.1 Safety function Safety function for pressure transmitters The safety function of SITRANS P refers to the measurement of pressures. An additional safety accuracy of 2% of the measuring range (complete span) must be added to the applicationspecific measuring error for an output current of 4 to 20 mA.
Functional safety 8.2 Device-specific safety information for single-channel operation (SIL 2) Checking the safety function Note You should check the safety function while the device is mounted, if possible. If this is not possible, you can also check the safety function when the device is not mounted. Make sure that the transmitter is mounted in the same position for testing as it is in in the system. Note If the transmitter is locked in Mode 10, deactivate the lock to check the safety function.
Functional safety 8.2 Device-specific safety information for single-channel operation (SIL 2) ● Explosion protection for corresponding versions ● Electromagnetic compatibility in compliance with EN 61326 8.2.4 Behavior in case of faults Repairs Defective devices should be sent in to the repair department with details of the fault and the cause. When ordering replacement devices, please specify the serial number of the original device. You will find the serial number on the nameplate.
Functional safety 8.3 Device-specific safety information for redundant operation (SIL 3) ● The SITRANS P pressure transmitter is only used in applications with a low demand for the safety function (low demand mode). ● Communication with the HART protocol is used only for the following: – Device configuration – Reading diagnostics values – However, it is not used for operations critical to safety. In particular, the simulation function must not be activated in safety-related operation.
Functional safety 8.3 Device-specific safety information for redundant operation (SIL 3) Note Use of remote seals If remote seals are used, the application-specific measurement error is the product of the transmitter and remote seal measurement errors. WARNING Disregarding conditions for fulfilling the safety function Disregard can result in a malfunction of the process plant or application, e.g. process pressure too high, maximum level exceeded.
Functional safety 8.3 Device-specific safety information for redundant operation (SIL 3) The PLC program must monitor the measured values of both DS III devices. As soon as the measured values differ by e.g. 2% or more, the system must be brought into the safe state and the fault must be located. Note Switching-off of system at high monitoring accuracy The two transmitters are connected to the process at different positions.
Functional safety 8.3 Device-specific safety information for redundant operation (SIL 3) ● Check the measuring accuracy, which must be within the range of the application-specific measuring error for the safety function. – Set the measured value display to a unit of pressure in Mode 13. – Check the zero point, e.g. in a pressureless state, for gauge and differential pressure. – Check the zero point for absolute pressure, e.g. by applying a defined pressure.
Functional safety 8.4 Add-on parts Checking safety You should regularly check the safety function of the entire safety circuit in accordance with IEC 61508/61511. The testing intervals are determined in calculations for each individual safety circuit in a system (PFDAVG). Electronics and measuring cell The safety function of the transmitter is ensured only if you use the electronics, measuring cell, display and connection board delivered by the factory. These components cannot be replaced. 8.3.

List of abbreviations B.1 Functional safety Abbreviation Full term in English Meaning MooN "M out of N" voting Classification and description of the safety-instrumented system in terms of redundancy and the selection procedures used. A safety-instrumented system or part that consists of "N" independent channels. The channels are connected to each other in such a way that "M" channels are in each case sufficient for the device to perform the safety instrumented function.
Glossary ATEX ATEX is an abbreviation of the French term "Atmosphère explosible" (potentially explosive atmosphere). ATEX stands for both EC directives in the area of explosion protection: ATEX product directive 94/9/EC and ATEX operating directive 1999/92/EC. Auxiliary power supply Auxiliary power supply refers to an electrical supply or reference voltage which some electrical circuits require apart from the standard supply.
Glossary Fault → Failure/Fault Fault tolerance Fault tolerance N means that a device can execute the intended task even when N faults exist. The device fails to execute the intended function in case of N+1 faults. Final controlling element Converter that converts electrical signals into mechanical or other non-electrical variables. Firmware Firmware (FW) is software that is embedded on a chip in electronic devices – in contrast to software which is saved on hard disks, CD-ROMs or other media.
Glossary Non-volatile memory → EEPROM Risk The combination of probability of a damage occurring and its magnitude. Safety function Defined function executed by a safety-instrumented system with the objective of achieving or maintaining a safe system status taking into account a defined dangerous occurrence.
Glossary The achievable SIL is determined by the following safety characteristics: ● Average probability of dangerous failure of a safety function in case of demand (PFDAVG) ● Hardware fault tolerance (HFT) ● Safe failure fractions (SFF) srli2 → srlin2 srlin2 "srli2" or "srlin2" is a type of square root extracting characteristic curve for the output current.
