压力控制器使用说明书
面板显示说明：
该表已根据要求将量程设成最好状态
只需要对报警进行设定就可以了
压力换算成显示值公式如下表：
显示值1个字表示0.001 mBar=1Pa
显示10个字就是0.01mBar=10Pa
显示100个字就是0.1mBar=100Pa
显示1000个字就是1mBar=1000Pa=1Kpa
具体的要看提供的压力控制要求来调整量程和报警控制
压力开关原理及工作电路
气体的压力经过压力传感器转换成电流信号通过压力控制器的主CPU处理后显示在控制控制器的PV屏上。
控制的压力值显示在SV屏上，控制压力可以根据实际环境的要求设定，实现全智能控制模式。
继电器带有常开/常闭触点，可以根据现场的要求进行状态设定，以满足现场的要求。
离合器使用说明书(压力控制器)
4、三号压力控制器（工作压力检测）压力调到 6.5kg/cm2（0.65MPa）。 5、减压阀压力调到 7kg/cm2。(0.7MPa) 6、若整个系统连锁正常，有关设备均已处于"起动准备”状态，磨机启动前的准备工作
即告完成。 九、磨机的启动
启动磨机之前应作如下常规检查 1、确认减压阀、安全阀的调定压力符合规定，压力表的读数不低于 7 Kgf/cm2(0.7Mpa)； 2、检查整个系统是否漏气，发现问题，及时处理。 ㈠ 离合器的试启动 1、磨机主电机不开，调减压阀压力到 7～7.3kg/cm2，向离合器冲气，离合器冲气迅速无 堵塞。 2、离合器调好后放气迅速。 3、冲放数次。 ㈡ 磨机的启动 1、确认指示灯指示离合器内无大于 0.4kgf/cm2(0.04MPa)的压力后，启动磨机主电动机。 2、气动离合器电控箱上的绿灯亮时，电动机即已达到其同步转速。 3、电动机达到同步转速后，向离合器充气。磨机启动，此时应测定磨机由静止状态达到 额定转速所需的时间，磨机达到额定速度的时间不应超过 7 秒。 4、放出离合器里的压缩空气，使离合器脱开。 5、调整单向节流阀，使磨机由静止至达到额定转速的时间（加速全过程）在 4～7 秒之间 完成，拧紧背帽，锁紧调整螺钉。调整单向节流阀一定要针对磨机负荷条件进行。磨机满负荷 运行时单向节流阀全开。 6、必须避免连续三次以上的启动，防止烧坏离合器。两次启动的间隔时间不得少于 15 分钟。 十、离合器的维护 1、空压机 2～4 周定期排水。 2、进气‘分水滤汽器’每班定期排水排脏，出气‘分水滤汽器’每班定期排水排脏。冲 气不畅更换滤芯。 3、空压机定期更换润滑油。 十一、操作 首先要确认电动机控制柜上的指示灯指示离合器内无空气压力后，方能起动主电动机，
工作至关重要，要按规定的管子尺寸接入和接出气动控制系统。

Install the O-ring in the groove on either the Pressure Relief Valve casting or the integrated galvanic isolator.2. Place the PRV in the desired orientation. Be sure that the PRV is aligned with the opening Tightening the bolts with the PRVtilted to one side may damage the galvanic isolator.3. Apply a drop of thread locking compound on the threads of the bolts to prevent them from coming loose.4. Loosely install the bolts through the fl ange of the PRV.5. Uniformly tighten the bolts 3 time each in an alternating pattern to a fi nal torque of 140in/lb.1234Tighten bolts in an alternating pattern as shown at left.Complete the pattern for each bolt fi rst to 40 in/lb,then to 80 in/lb, and fi nally to 140 in/lb.3.3 USE WITH SALT WATERUse with salt water is permissible provided the equipment is thoroughly cleaned with fresh water after each use. The service life ofthe equipment may be shortened due to the e ff ects of corrosion, and is not covered under warranty.4.0 RELIEF VALVE PRESSURE SETTINGTo set the relief valve pressure, turn the adjusting screw on the relief valve housing until the surface of the screw is even with the step marked with the desired pressure.Do not cap or plug discharge opening.To turn o ff the Pressure Relief Valve, align the adjusting screw with the OFF position. Placing the Pressure Relief Valve in the OFF position prevents the valve from venting water. Do not use the OFF position for normal operations. System damage may occur if the Pressure Relief Valve is in the OFF position and the system exceeds its operating limits.The Pressure Relief Valve meets the requirements of NFPA 1901.90 PSI200 PSIOFFUse a 1/4” (7mm) hex key or 9/16” (14mm) socket/wrench when setting the height of the adjusting screw to the desired relief pressure.The Pressure Relief Valve is disabled in the OFF position and off ers no system protection against over-pressurization. Avoid water hammer or other pressure spikes during pump tests. Ensure PRV is returned to its normal pressure setting following pump testing.Severe water hammer may cause pressure spikes exceeding the Pressure Relief Valve’s capacity. Large spikes can result in injury from ruptured hose or system components. Review fl ow capacity of the Pressure Relief Valve. Add more PRVs if additional fl ow capacity is needed. Always operate valves slowly to avoid the risk of water hammer.5.0 RELIEF VALVE FLOW vs. PRESSURE CURVE6©Copyright Task Force Tips LLC 2004-2019 LIA-202 November 12, 2019 Rev056.0 WARRANTYTask Force Tips LLC, 3701 Innovation Way, Valparaiso, IN 46383-9327 USA (“TFT”) warrants to the original purchaser of its Pressure Relief Valve (“equipment”), and to anyone to whom it is transferred, that the equipment shall be free from defects in material and workmanship during the fi ve (5) year period from the date of purchase.TFT’s obligation under this warranty is specifi cally limited to replacing or repairing the equipment (or its parts) which are shown by TFT’s examination to be in a defective condition attributable to TFT.

All applicable legal or institutional installation regulations must be complied during installation.The device contains electrical and electronic components and must not be disposed of as household refuse. All locally valid regulations and requirements must be observed.ApplicationMode of operationFlow measurement Product featuresWater-side control of heating and cooling systems for AHUs and water coils.The HVAC performance device is comprised of three components: characterized control valve (CCV), measuring pipe with flow sensor and the actuator itself. The adjusted maximum flow (V'max) is assigned to the maximum control signal (typically 100%). The HVAC performance device can be controlled via communicative signals. The fluid is detected by the sensor in the measuring pipe and is applied as the flow value. The measured value is balanced with the setpoint. The actuator corrects the deviation by changing the valve position. The angle of rotation α varies according to the differential pressure through the control element (see flow curves).All flow tolerances are at 68°F [20°C] & water.Flow rate curvesControl characteristics The fluid velocity is measured in the measuring component (sensor electronics) and converted to a flow rate signal.The control signal Y corresponds to the power Q via the exchanger, the volumetric flow isregulated in the EPIV. The control signal Y is converted into a linear characteristic curve andprovided with the V'max value as the new reference variable w. The momentary controldeviation forms the control signal Y1 for the actuator.The specially configured control parameters in connection with the precise flow rate sensorensure a stable quality of control. They are however not suitable for rapid control processes, i.e.for domestic water control. U5 displays the measured flow as voltage (factory setting).Parametrizing V'max with ZTH:U5 refers to the respective V'nom, i.e. if V'max is e.g. 50% of V'nom, then Y = 10 V, U5 = 5 V.Parametrizing V'max with PC-Tool:In the PC-Tool, the maximum flow rate to which U5 refers can be set individually. If V'max ischanged (e.g. to 70% V'nom), the U5 flow range is also automatically changed to the same value(e.g. 70% V'nom: U5 = 10 V). This adjustment can be reversed by entering a value manually (U5flow range = 100%: U5 refers to V'nom).As an alternative, U5 can be used for displaying the valve opening angle.Creep flow suppressionConverter for sensorsControl signal inversionHydronic balancing Combination analogue - communicative(hybrid mode)Manual override Flow controlV'nom is the maximum possible flow.V'max is the maximum flow rate which has been set with the highest control signal DDC. V'maxcan be set between 25% and 100% of V'nom.Given the very low flow speed in the opening point, this can no longer be measured by the sensor within the required tolerance. This range is overridden electronically.Opening valveThe valve remains closed until the flow required by the control signal DDC corresponds to 1% of V'nom. The control along the flow characteristic is active after this value has been exceeded. Closing valveThe control along the flow characteristic is active up to the required flow rate of 1% of V'nom. Once the level falls below this value, the flow rate is maintained at 1% of V'nom. If the level falls below the flow rate of 0.5% of V'nom required by the control signal DDC, then the valve willclose.Connection option for a sensor (active or with switching contact). In this way, the analog sensor signal can be easily digitized and transferred to the bus systems BACnet, Modbus or MP-Bus.This can be inverted in cases of control with an analog control signal. The inversion causes the reversal of the standard behavior, i.e. at a control signal of 0%, is equal to V'max, and the valve is closed at a control signal of 100%.With the Belimo tools, the maximum flow rate (equivalent to 100% requirement) can be adjusted on-site, simply and reliably, in a few steps. If the device is integrated in the management system, then the balancing can be handled directly by the management system. With conventional control by means of an analog control signal DDC, BACnet, Modbus, or MP-Bus can be used for the communicative position feedback.Manual control with push-button possible - temporary. The gear train is disengaged and the actuator decoupled for as long as the button is pressed.Product featuresAccessoriesTools Description TypeConverter Bluetooth / NFC ZIP-BT-NFC Electrical installationSupply from isolating transformer.The wiring of the line for BACnet MS/TP / Modbus RTU is to be carried out in accordance withapplicable RS485 regulations.Modbus / BACnet: Supply and communication are not galvanically isolated.

The ball valve may not be installed in ahanging position, i.e. with the stem pointing downwards.Installation in the return is recommended.The water quality requirements specified in VDI 2035 must be adhered to.Belimo valves are regulating devices. For the valves to function correctly in the long term, they must be kept free from particle debris (e.g. welding beads during installation work). The installation of a suitable strainer is recommended.Ball valves, rotary actuators and sensors are maintenance-free.Before any service work on the control element is carried out, it is essential to isolate the rotary actuator from the power supply (by unplugging the electrical cable if necessary). Any pumps in the part of the piping system concerned must also be switched off and the appropriate slide valves closed (allow all components to cool down first if necessary and always reduce the system pressure to ambient pressure level).The system must not be returned to service until the ball valve and the rotary actuator have been correctly reassembled in accordance with the instructions and the pipeline has been refilled by professionally trained personnel.The direction of flow, specified by an arrow on the housing, is to be complied with, since otherwise the flow rate will be measured incorrectly.

The valve must not be subjected to excessive stress caused by pipes or fittings.In order to achieve the specified measuring accuracy, a flow-calming section or inflow section in the direction of the flow is to be provided upstream from the flow sensor. Its dimensions shouldbe at least 5x DN.The valve-actuator combination may be mounted separately from the flow sensor. The direction of flow of both components must be observed.Installation notesBehaviour in case of sensor failureGeneral notesIn case of a flow sensor error, the EPIV will switch from flow control to position control.Once the error disappears, the EPIV will switch back to the normal control setting.DimensionsDimensional drawingsTypeWeight EP050+ARX-E N4HH[]ABC D E F 26.6" [675]12.0" [305]6.3" [159]9.5" [241] 3.4" [86]3.4" [86]。
