This warns you of a potential hazard that could lead to bodily injury up to and including death if the corresponding instructions are not followed.WARNING: This warns you of a potential hazard that could lead to significant property damage if corresponding instructions are not followed.INFORMATION This indicates that the corresponding information is important for operating the instrument properly.PU/PI and PS10 Instruction Manual2 Instrument descriptionThe PU/PI and PS10 pressure transducers are pneumatic, electronic sensors for measuring overpressures, vacuum pressures and differential pressures. Typical applications include, for instance, pressure measurements in air-conditioning and ventilation ducts. At the heart of the transducer is a pressure measurement capsule with a beryllium bronze membrane spring, which is displaced by the pressure difference between the two chambers of the measurement capsule. Inductive displacement transducers measure membrane deflection without contacting the membrane. The instrument has no frictional parts or parts subject to mechanical wear.3 Start-up3.1 FeaturesAlthough the PU/PI and PS 10 pressure transducers are highly robust, they are nevertheless precision instruments and should be handled with care. Avoid mounting the instruments in the direct vicinity of any sources of radiation or heat, such as heaters, as this could result in measurement errors. Ideally, the instrument should be mounted vertically on a wall not subject to vibration. Pressure (+) and vacuum (-) ports should be pointing down in order to prevent any condensation from entering the measurement cell.When connecting pressure to the transducer, use the following table to ensure that the sign of the pressure (+ or -) is correct.PU/PI and PS10 Instruction Manual3.2Supply voltage connections in the instrument:Figure 1: Configuration of circuit board: (not all components are shown)P0Observe the required supply voltage (see rating plate) as well as the connection diagram located on the housing cover / circuit board mount. 3.3Analog output connections in the instrumentThe transducer outputs are protected from short circuits. Instruments supplied with direct current are also protected from reverse polarityPU/PI and PS10 Instruction ManualDisplay-connector4 Calibrating the zero pointPlease remember that it takes roughly 30 to 60 minutes for the pressuretransducer to warm up after it is switched on. The output signal may notremain stable during this period.It is recommended that the zero point after a long operating time(approximately 6 months) is checked and if necessary calibrate it again.The wiring of the current outputmakes it impossible to enter a negative current.As a result, operators cannot turn the zero-point potentiometer beyond the0.0 mA mark when calibrating the zero point. Were this not the case, thenegative component, which cannot be displayed, would interfere with theoutput signal.After the pressure transducer has warmed up, the operator may calibrate the zeropoint using the P0 trimmer (see figure 1). The following table may be used to look up the value to which the analog output must be set when the ports are open; this value is dependent upon both the measurement range and the output signal.PU/PI and PS10 Instruction Manual 5 TroubleshootingPU/PI and PS10 Instruction Manual 6 Technical dataPU/PI and PS10 Instruction ManualAppendix A: Parts in contact with measurement medium∙ Beryllium bronze CuBe2 ∙ Araldite CY236 / HY988∙ Mu metal (nickel alloy) ∙ Loctite 242e∙ Brass CuZn39Pb3 ∙ Carbonyl iron∙ Aluminum AlCuMgPb / AlMg3 ∙ KEL (FPM: fluorinated rubber) ∙ Silicon (tubing) optional: Viton ∙ Vepuran Vu 4457/51∙ Crastin (PTBP) ∙ UHU-Plus endfest 300 binder。

The display will show the previous switching pressure setting, and the dotted bar will flash while the button is pressed down (case 1).You can now use the cursor keys to adjust the switching point upwards or downwards. If a cursor key is held down, the values will change faster. When the cursor key is released again, the switch-on pressure setting will cease to change. This setting is stored and activated when the SP button is released, after which the display will show the current pressure value and the bar will quit flashing.b)Adjusting the reset point.Case 3 or Case 4Press and hold the RP button. The display will show the previous reset pressure setting, and the dotted bar will flash while the button is pressed down.You can now use the cursor keys to adjust the reset point in the same manner as described above.During both adjustment operations, it may occur that the hysteresis graph changes from one state to another at the time a transition is made through the point "Switching pressure = Reset pressure".When both points are correctly set, the hysteresis graph will also be correct. You can change between SP and RP as often as you wish until the settings are correct.c) Setting a buffering time.In order to prevent brief pressure “spikes”or “surges” from causing undesiredswitching, a buffering time can be entered.The effect of this is that pressure changes are evaluated only if the pressure signal in question is present for longer than the buffering time. In order to set a buffering time, press the button SP before the powersupply is switched on. Release this button again after the power supply has beenswitched on. The display will then show the buffering time in milliseconds (e.g. 03) or seconds. The cursor buttons w , v can be used to set the buffering time to 03, 06,12, 24 or 50 ms or 0.1, 0.2 or 0.4seconds. When this has been done, press SP to store the setting.d) Setting the pressure switch to ambient pressure = 0.Since ambient pressure varies according to altitude, the user may re-calibrate the zero point to match local conditions.Press the button RP before the power supply is switched on. Release this button again after the power supply has been switched on and the display test has run.The display will then show "OFS". Thecursor buttons w , v can be used to set the pressure display to 0. When this has been done, press SP to store the setting.e) Hysteresis modeIf it is desired to operate with a fixedhysteresis value instead of the reset point,this value can be selected as desired.In order to set a hysteresis value, the two buttons SP and w must be pressed simultaneously before the power supply is switched on.Release these buttons again after thepower supply has been switched on and the display test has run. The display will then show the operating mode. The cursor buttons v ,w can now be used to change the operating mode until "HYS" appears in the display. When this has been done,press SP to store the setting.The SP button can be used to display the switching-point setting, which can be modified by means of the cursor buttons v ,w .The button RP can be used to display the hysteresis setting, which can also be modified by means of the cursor buttons v ,w .Negative hysteresis means: Signal “on”with rising pressure (case 1).Positive hysteresis means: Signal “on” with falling pressure (case 2).If the switching point is modified, this will automatically also result in a change in the reset point by a value equal to the hysteresis setting.Case 2f) Window modeIf it is desired to monitor whether the pressure lies within a certain range, a switching window can be created for this purpose. The pressure switch will then indicate cases in which the actual pressure lies above or below this area.In order to set a switching window, the two buttons SP and w must be pressedsimultaneously before the power supply is switched on.Release these buttons again after the power supply has been switched on and the display test has run. The display will then show the operating mode.The cursor buttons v ,w can now be used to change the operating mode until "FEn"(standing for "Window") in the display. When this has been done, press SP to store the setting. The button SP can be used to display the switching-point setting, which can bemodified by means of the cursor buttons w , v .The distance between the switching point and reset point is the switching window. If theswitching point is lower than the reset point, a signal will be output as long as the pressure lies within the preset window (case 1, rising pressure). If the switching point is higher than the reset point, a signal will be output as long as the pressure lies outside the preset window (case 2, rising pressure). In the case of falling pressure, the signal is inverted.Case 1Std =Standard mode, switching and resetpoints adjustableHYS =Hysteresis mode, switching point andhysteresis adjustableFEn =Window mode, switching windowadjustableA DJUSTING THE S WITCHING P OINTS (SP) AND R ESET P OINTS (RP)Switching Characteristic Graphs Signal “on” with rising pressure Setting SP* > RP**When the switching point (SP) is adjusted HIGHER than the reset point (RP), then the switching output will be “normally off”.

压力释放阀PRESSURE RELEASE VALVE使用说明书OPERATION INSTRUCTION明远电器设备SHENYANG MINGYUAN ELECTRIC EQUIPMENT CO., Ltd.本说明书适用于我公司生产的系列变压器用压力释放阀，阐述其用途、性能、规格、技术参数、使用及安装，供用户参考。
The Operation Instruction is applicable to pressure release valve of a series of transformers manufactured by our company, indicating its application, performances, specifications, technical parameters, usage and installation for uses’ reference.1. 压力释放阀用途和性能压力释放阀适用于油浸式电力变压器、电力电容器及有载分接开关等，用来保护油箱。
当油浸式变压器在运行中出现故障时，由于线圈过热，使一部分变压器油汽化，变压器油箱中压力迅速增加，这时压力释放阀在2ms迅速动作，释放压力，保护油箱不致变形或爆裂。
油箱的压力再升高而达到开启压力时，压力释放阀应再次动作，直到油箱的压力降到正常值。
由于压力释放阀动作后能可靠关闭，油箱外的水和空气不能进入油箱，变压器部不会受大气污染。
1.Application and performancePressure release valves play a vital role in the protection of oil-immersed electrical equipments, such as transformers, high voltage switch gears, capacitor and on load tap-changers, etc. This device can prevent the oil-immersed electrical equipment from deformation or rupture. Should a fault occur in such electrical equipment, from deformation of rupture? Should a fault occurring in such electrical equipment, they are instantaneously vaporize the oil causing extremely rapid build-up of gaseous pressure?
