Digital compensation of sensor offset, sensitivity, temperature drift and non-linearity is accomplished via a 16-bit RISC micro-controller running a correction algorithm with calibration coefficients stored in an EEPROM.The ZMD31150 is adjustable to nearly all bridge sensor types. Measured values are provided at the ratiometric analog voltage output or at the digital ZACwire TM and I2C interface. The digital interface can be used for a simple PC-controlled calibration procedure, in order to program a set of calibration coefficients into an on-chip EEPROM. Thus a specific sensor and a ZMD31150 are mated digitally: fast, precise and without the cost overhead associated with trimming by external devices or laser.The ZMD31150 is optimized for automotive environments by it’s special protection circuitry and excellent electromagnetic compatibility.• Evaluation kit available with samples• Mass calibration solutionFig 1: Sensor Module Schematichttps://ZMD31150Advanced Automotive Sensor Signal ConditionerDatasheet PRELIMINARY Contents1.CIRCUIT DESCRIPTION (3)1.1S IGNAL F LOW (3)1.2A PPLICATION M ODES (4)1.3A NALOG F RONT E ND (AFE) (4)1.3.1.Programmable Gain Amplifier (4)1.3.2.XZC - Analog Sensor Offset Compensation (5)1.3.3.Measurement Cycle (6)1.3.4.Analog-to-Digital Converter (6)1.4T EMPERATURE M EASUREMENT (7)1.5S YSTEM C ONTROL AND C ONDITIONING C ALCULATION (8)1.5.1.Operation Modes (8)1.5.2.Start Up Phase (8)1.5.3.Conditioning Calculation (9)1.6A NALOG O UTPUT AOUT (9)1.7S ERIAL D IGITAL I NTERFACE (10)1.8S AFETY F EATURES, W ATCHDOG AND E RROR D ETECTION (10)1.9H IGH V OLTAGE, R EVERSE P OLARITY AND S HORT C IRCUIT P ROTECTION (10)https://2.APPLICATION CIRCUIT EXAMPLE (11)3.ESD-PROTECTION (12)4.PIN CONFIGURATION, LATCH-UP AND PACKAGE (12)5.IC CHARACTERISTICS (13)5.1A BSOLUTE M AXIMUM R ATINGS (13)5.2O PERATING C ONDITIONS (13)5.3E LECTRICAL P ARAMETERS (14)5.4I NTERFACE C HARACTERISTICS & EEPROM (16)6.RELIABILITY (17)7.CUSTOMIZATION (17)8.RELATED DOCUMENTS (17)ZMD31150Advanced Automotive Sensor Signal ConditionerDatasheetPRELIMINARY1.Circuit Description1.1Signal FlowFig.2: Block diagram of ZMD31150The ZMD31150’s signal path is partly analog (blue) and partly digital (red). The analog part is realized differential – this means the differential bridge sensor signal is internal handled via two signal lines, which are rejected symmetrically around a common mode potential (analog ground = VDDA/2). Consequently it is possible to amplify positive and negative input signals, which are located in the common mode range of the signal input.The differential signal from the bridge sensor is pre-amplified by the programmable gain amplifier (PGA). The Multiplexer (MUX) transmits the signals from bridge sensor, external diode or separate temperature sensor to the ADC in a certain sequence (instead of the temp. diode the internal pn-junction (TS) can be used optionally). Afterwards the ADC converts these signals into digital values. The digital signal correction takes place in the calibration micro-controller (CMC). It is based on a correction formula located in the ROM and on sensor-specific coefficients (stored into the EEPROM during calibration). Dependent on the programmed output configuration the corrected sensor signal isoutput as analog value or in digital format (I 2C, ZACwire TM ). The configuration data and the correction parameters can be programmed into the EEPROM via the digital interfaces.https://ZMD31150Advanced Automotive Sensor Signal ConditionerDatasheetPRELIMINARY1.2Application ModesFor each application a configuration set has to be established (generally prior to calibration) by programming the on-chip EEPROM regarding to the following modes:Sensor channel− Sensor mode : ratiometric bridge excitation in voltage or current supply mode.− Input range : the gain adjustment of the AFE with respect to the maximum sensor signal spanand the zero point of the ADC has to be chosen− Additional offset compensation XZC : the extended analog offset compensation has to beenabled if required, e.g. if the sensor offset voltage is near to or larger than the sensor span. − Resolution/response time : the A/D converter has to be configured for resolution and convertingscheme or ADC Order (first or second order). These settings influence the sampling rate, signal integration time and this way the noise immunity. Temperature− Temperature measurement : the source for the temperature correction has to be chosen.1.3 Analog Front End (AFE)The analog front end consists of the PGA, the MUX and the ADC. 1.3.1.Programmable Gain AmplifierTable 1 shows the adjustable gains, the sensor signal spans and the allowed common mode range.Input common mode rangeV IN_CM in % VDDA 2 No. overall gain a IN Max. span V IN_SP [mV/V] 1 Gain Amp1 Gain Amp2 Gain Amp3 XZC=off XZC=on 1 420 1,8 30 7 2 29 ... 65 45...55 2 280 2,7 30 4,66 2 29 ... 65 45...55 3 210 3,6 15 7 2 29 ... 65 45...55 4 140 5,4 15 4,66 2 29 ... 65 45...55 5 105 7,1 7,5 7 2 29 ... 65 45...55 6 70 10,7 7,5 4,66 2 29 ... 65 45...55 7 52,5 14,3 3,75 7 2 29 ... 65 45...55 8 35 21,4 3,75 4,66 2 29 ... 65 45...55 9 26,3 28,5 3,75 3,5 2 29 ... 65 45...55 10 14 53,75 1 7 2 29 ... 65 45...55 11 9,3 80 1 4,66 2 29 ... 65 45...55 12 7 107 1 3,5 2 29 ... 65 45...55 13 2,8 267 1 1,4 2 32 (57)Table 1: Adjustable gains, resulting sensor signal spans and common mode ranges1Recommended internal signal range is 75% of supply voltage in maximum.

XZC - Analog Sensor Offset CompensationThe ZMD31150 supports two methods of sensor offset compensation (zero shift):• digital offset correction• XZC - analog compensation for large offset values(up to in maximum approximately 300% of span, depending on gain adjustment)Digital sensor offset correction will be processed at the digital signal correction/conditioning by the CMC. Analog sensor offset pre-compensation will be needed for compensation of large offset values, which would be overdrive the analog signal path by uncompensated gaining. For analog sensor offset pre-compensation a compensation voltage will be added in the analog pre-gaining signal path (coarse offset removal). The analog offset compensation in the AFE can be adjusted by 6 EEPROM bits.PGA gaina IN Max. spanV IN_SPin mV/VOffset shift per stepin % full spanApprox. maximumoffset shift in mV/VApprox. maximumshift in [% V IN_SP](@ ± 31)420 1,8 12,5% 7,8 388% 280 2,7 7,6% 7,1 237% 210 3,6 12,5% 15,5 388% 140 5,4 7,6% 14,2 237% 105 7,1 5,2% 13 388% 70 10,7 7,6% 28 237% 52,5 14,3 5,2% 26 388% 35 21,4 7,6% 57 237% 26,3 28,5 5,2% 52 161% 14 53,75 12,5% 194 388% 9,3 80 7,6% 189 237% 7 107 5,2% 161 161% 2,8 267 0,83% 72 26% Table 2: Analog Zero Point Shift Ranges (XZC)https://ZMD31150Advanced Automotive Sensor Signal ConditionerDatasheet PRELIMINARY1.3.3. Measurement CycleThe Multiplexer selects, depending on EEPROM settings, the following inputs in a certain sequence. Temperature measured by external diodeInternal offset of the input channel (V OFF)Pre-amplified bridge sensor signalThe complete measurement cycle iscontrolled by the CMC. The cycle diagram atthe right shows its principle structure.The EEPROM adjustable parameters are:• n=<1,31>: Pressure measurement countAfter power on the start routine is called,which contains all needed measurementsonce.Remark: The tasks “CMV”, “SSC/SCC+” and“SSC/SCC-“ are contained independent fromEEPROM configuration always in cycle.1.3.4. Analog-to-Digital ConverterThe ADC is an integrating AD-Converter in fulldifferential switched capacitor technique.Programmable ADC-resolutions are r ADC=<13,14> and with segmentation <15,16> bit.It can be used as first or second order converter. In the first order mode it is inherently monotone and insensitive against short and long term instability of the clock frequency. The conversion cycle time depends on the desired resolution and can be roughly calculated by:t CYC_1 = 2rµs / 2 / f CLKIn the second order mode two conversions are stacked with the advantage of much shorter conversion cycle time and the drawback of a lower noise immunity caused by the shorter signal integration period. The conversion cycle time at this mode is roughly calculated by:t CYC_2 = 2(r+3)/2 / 2 / f CLKThe calculation formulas give a overview about conversion time for one AD-conversion. Refer Calculation sheet “ZMD31150_Bandwidth_Calculation_Rev*.xls” for detailed calculation of samplingtime and bandwidth.ZMD31150Advanced Automotive Sensor Signal ConditionerDatasheet PRELIMINARYThe result of the AD conversion is a relative counter result corresponding to the following equation: Z ADC = 2r * (V ADC_DIFF / V ADC_REF - RS ADC)Z ADC: number of counts (result of the conversion)r: adjusted resolution in bitV ADC/REF_DIFF: differential input/reference voltage of ADCRS ADC: digital ADC Range Shift (RS ADC = 1/16, 1/8, 1/4, 1/2, controlled by the EEPROM content) With the RS ADC value a sensor input signal can be shifted in the optimal input range of the ADC.ADC Adjustment approx.

Otherwise ADC resolution should bemore than one bit higher than applied output resolution.*2) The sampling rate (AD conversion time) is only a part of the whole cycle,refer “ZMD31150 bandwidth calculation sheet” for detailed informationRemark:ADCs reference voltage ADC VREF is defined by the potential between <VBR_T> and <VBR_B> (or <VDDA> to <VSSA>, if CFGAPP:BREF=1). The theoretically input range ADC RANGE_INP of the ADC is equivalent to ADCs reference voltage.In practice ADCs input range should be used in maximum from 10% to 90% of ADC RANGE_INP- a necessary condition for abiding specified accuracy, stability and nonlinearity parameters of AFE. These condition is also valid for whole temperature range and all applicable sensor tolerances. Inside of ZMD31150 is no failsafe task implemented, which verifies abiding of these condition.https://ZMD31150Advanced Automotive Sensor Signal ConditionerDatasheet PRELIMINARY1.4 Temperature MeasurementThe ZMD31150 supports four different methods for temperature data acquiring needed for calibration of the sensor signal in temperature range. Temperature data can be acquired using:• an internal pn-junction temperature sensor,• an external pn-junction temperature sensor connected to sensor top potential (VBRTOP),• an external resistive half bridge temperature sensor and• the temperature coefficient of the sensor bridge at bridge current excitation.Refer “ZMD31150 Functional Description” for a detailed explanation of temperature sensor adaptation and adjustment.1.5 System Control and Conditioning CalculationThe system control supports the following tasks/features:• control the measurement cycle regarding to the EEPROM-stored configuration data• 16 bit correction calculation for each measurement signal using the EEPROM stored calibration coefficients and ROM-based algorithms = signal conditioning• manage start up sequence and start signal conditioning• handle communication requests received by the serial interface• failsafe tasks for the functions of ZMD31150 and message detected errors with diagnostic stateshttps://Refer “ZMD31150_FunctionalDescription_Rev_*.PDF” for a detailed description.1.5.1. Operation ModesThe internal state machine represents three main states:• the continuous running signal conditioning mode – called N ormal O peration M ode: NOM• the calibration mode with access to all internal registers and states – called C ommand M ode: CM • the failure messaging mode – called D iagnostic M ode: DM1.5.2. Start Up Phase1The start up phase consist of following parts:1 internal supply voltage settling phase (=potential VDDA-VSSA) – finished by disabling the resetsignal through the power on clear block (POC). Refer “ZMD31150_HighVoltageProt_Rev_*.PDF”, chapter 4 for power on/off thresholds.Time (for beginning with VDDA-VSSA=0V): 500µs to 2000µs, AOUT: tristate2 system start, EEPROM read out and signature check (and ROM-check, if CFGAPP:CHKROM=1).Time: ~200µs (~2000µs with ROM-check), AOUT: LOW (DM)3 processing the start routine of signal conditioning (all measures & conditioning calculation).Time: 5x AD conversion time, AOUT behavior depending on adjusted OWI mode (1.6):- OWIANA & OWIDIS => AOUT: LOW (DM)- OWIWIN & OWIENA => AOUT: tristate1 All described timings are roughly estimated values and correlates with internal clock frequency. Timings estimated for fclk=3MHz.ZMD31150Advanced Automotive Sensor Signal ConditionerDatasheet PRELIMINARY The analog output AOUT will be activated at the end of start up phase depending on adjusted output and communication mode (1.6). In case of detected errors Diagnostic Mode (DM) is activated and diagnostic output signal is driven at the output.After the start up phase the continuous running measurement and calibration cycle is started. Refer “ZMD31150_BandwidthCalculation_Rev_*.xls” for detailed information about output update rate.1.5.3. Conditioning CalculationThe digitalized value for pressure (acquired raw data) is processed with the correction formula to remove offset and temperature dependency and to compensate non-linearity up to 3rd order. The result of the correction calculation is a non-negative 15 Bit value for pressure (P) in the range [0; 1). This value P is clipped with programmed limitation coefficients and continuously written to the output register of the digital serial interface and the output DAC.Note: The conditioning includes up to third order nonlinearity sensor input correction. The available adjustment ranges depend on the specific calibration parameters, for a detailed description refer to “ZMD31150 Functional Description”. To give a rough idea: Offset compensation and linear correction are only limited by the loose of resolution it will cause, the second order correction is possible up to about 30% full scale difference to straight line, third order up to about 20% (ADC resolution = 13bit). The used calibration principle is able to reduce present nonlinearity errors of the sensor up to 90%. The temperature calibration includes first and https://second order correction and should be fairly sufficient in all relevant cases. ADC resolution influences also calibration possibilities – 1 bit more resolution reduces calibration range by approximately 50%. Calculation input data width is in maximum 14bit. 15 & 16bit ADC resolution mode uses only a 14 bit segment of ADC range.1.6 Analog Output AOUTThe analog output is used for output the analog signal conditioning result and for “End of Line” communication via the ZACwire TM interface (one wire communication interface - OWI). The ZMD31150 supports four different modes of the analog output in combination with OWI behavior:• OWIENA: analog output is deactivated, OWI communication is enabled• OWIDIS: analog output is active (~2ms after power on), OWI communication is disabled• OWIWIN: analog output will be activated after time window,OWI communication is enabled in time window of ~500ms in maximum,transmission of “START_CM” command has to be finished during time window• OWIANA: analog output will be activated after ~2ms power on time,OWI communication is enabled in time window of ~500ms in maximum,transmission of “START_CM” command has to be finished during time window,to communicate the internal driven potential at AOUT has to be overwrittenby the external communication master (AOUT drive capability is current limited)The analog output potential is driven by an unity gain output buffer, those input signal is generated by an 12.4bit resistor string DAC. The output buffer (BAMP) – a rail-to-rail OPAMP - is offset compensated and current limited. So a short circuit of analog output to ground or power supply does not damage the ZMD31150.ZMD31150Advanced Automotive Sensor Signal ConditionerDatasheet PRELIMINARY1.7 Serial Digital InterfaceThe ZMD31150includes a serial digital interface (SIF), which is used for communication with the circuit to realize calibration of the sensor module. The serial interface is able to communicate with two communication protocols – I2C TM and ZACwire TM (an one wire communication interface – also called OWI). The OWI can be used to realize a “End of Line” calibration via the analog output AOUT of the complete assembled sensor module.Refer “ZMD31150 Functional Description” for a detailed description of the serial interfaces and communication protocols.1.8 Failsafe Features, Watchdog and Error DetectionThe ZMD31150 detects various possible errors. A detected error is signalized by changing the interal status in diagnostic mode (DM). In this case the analog output is set to LOW (minimum possible output value = lower diagnostic range – LDR) and the output registers of the digital serial interface are set to a significant error code.A watchdog oversees the continuous working of the CMC and the running measurement loop. The operation of the internal clock oscillator is verified continuously by oscillator fail detection.A check of the sensor bridge for broken wires is done permanently by two comparators watching thehttps://input voltage of each input (sensor connection and short check). Additionally the common mode voltage of the sensor and sensor input short is watched permanently (sensor aging).Different functions and blocks in digital part - like RAM-, ROM-, EEPROM- and register content - are watched continuously. Refer “ZMD31150 Functional Description” for a detailed description of safety features and methods of error messaging.1.9 High Voltage, Reverse Polarity and Short Circuit ProtectionThe ZMD31150 is designed for 5V power supply operation.The ZMD31150 and the connected sensor is protected from overvoltage and reverse polarity damage by an internal supply voltage limiter. The analog output AOUT can be connected (short circuit, overvoltage and reverse) with all potentials in protection range under all potential conditions at the pins VDDE and VSSE.All external components – explained in application circuit in chapter 2 – are required to guarantee these operation, the protection is no time limited. Refer “ZMD31150 High Voltage Protection Description” for a detailed description of protection cases and conditions.ZMD31150Advanced Automotive Sensor Signal ConditionerDatasheet PRELIMINARY 2.

五、正常检修注意事项
当系统检修或进行正常手动倒闸操作时，此时需要将装置的出口闭锁压板打到“闭锁”位置，完成检修等工作后，把装置出口闭锁压板退出。
六、 UPS电源
对于部分380伏的低压变电所因没有不间断电源，为保证装置正常工作，由UPS电源给310 装置供电。注意：在整个变电所全部停电时要关掉UPS 电源，以防止UPS电源存储的电量释放完后，再次投运时310装置无法工作；

三、装置自动解除闭锁
装置每动作一次会闭锁装置,外部恢复正常后，装置会15秒后自动解除闭锁，准备下次动作。
四、手动切换
手动切换是指双进线运行方式恢复到双进线加母联运行方式的一种操作方式，若实现了一次切换后，要恢复到双进线加母联运行方式时，按手动切换按钮即可实现。
