1.DESCRIPTION描 述
These units are intended for use as regulators/reducers (to10,25 or 50 bars depending on the catalogue data sheet)for pure gases stored at high pressure(200 bars) in cylinders or packs. They enable a gas distribution network to be supplied continuously by automatic switching to a reserve source before the source in service has run out.
这些产品是适用于钢瓶内储存的高压（200Bar）高纯气体的调压阀/减压器（压力减到10Bar，25Bar，或50Bar，参照目录数据）。在工作气源使用完之前通过自动切换到备用气源，来实现气体分配系统的持续供气。
The operational of the semi-automatic changeover manifold is based on the use of two pressure regulators connected together by their LP(Low Pressure)outlet. Priority selection is made by means of a lever, which operates the relief screws of the pressure regulators.
When the operational gas source runs out, the pressure drop causes the other pressure regulator to open automatically.
半自动切换面板的运行基于两个调压阀在LP（低压）出口处相连接。开启使用两气瓶的顺序操作是利用操纵杆来实现，用操纵杆操作释放调压阀的螺钉，当一边供气气瓶用完，压力下降引起另一边调压阀自动打开，实现自动切换。
The only operator action consists in changing the empty cylinders or packs, after switching the lever to the side which corresponds to the new operational source in order to restore the normal pressure, which explains why the system is called ”semi-automatic”.
This equipment is designed and approved for a continuous gas supply installation. It is not intended for any other installation or purpose. If the product user has any questions regarding this product’s proper application or purpose, the product user should call+33 380 476 100.Any non-approved use or application and/or any non-approved modification lf the product or its use or application may result in serious accident or personal injury. SMT is not responsible for any non-approved use or application.
仅有的操作动作是换下空钢瓶，在换钢瓶之前将操纵杆扳到相应的工作气源的一边，目的是重建正常压力，这就是系统称为“半自动”的原因。这套设备适用于连续供气系统的安装，不适合安装于其他场合。如果用户对产品的适用范围有疑问，可以致电+33380 476 100。
任何未经许可的使用、应用或修改都可能造成事故或人身伤害。SMT不对任何未经许可的使用或应用负责。

B. General sealing check一般密封测试
Check that bleed valves(03G and 03D) and shut off valves(02G and 02G) are closed.
检查泄压阀（03G 和03D）及截止阀（02G 和02G）确保关闭。
Set the lever to the “up” or “down” position, depending on the source to be used first (the arrow shows the gas source which will be in service).
设置操纵杆到“up” 或 “down”的位置，此选项取决于首先被使用的气源（箭头指向供气端）。
Slowly open all cylinder valves (20G, 10G, 10D, 20D), and then close them. The pressure in the cylinders is read on the two high pressure gauges (05G and 05D).
缓慢打开所有钢瓶阀门(20G, 10G, 10D, 20D)，然后关闭它们。钢瓶压力在两个高压表（05G and 05D)上可读。
Check that the values indicated on the high pressure gauges do not vary, over a period of approximately one minute.
确保高压表所显示的数值不变，维持时间大约超过一分钟。
If there is a variation, this means that there is a leak. Find the leak using a leak detector. Once the leak has been located, open the bleed valves (03G and 03D), disassemble and check the connector, then retighten it.
如果数值有变化，说明有泄漏。用泄漏探测器找到泄漏处。一旦找到泄漏处，打开泄压阀，拆下并检查连接器，然后重新紧固。
C. Bleeding the unit and the installation吹扫和安装部件
Check that valves (02G and 02D) and bleed valves (03G and 03D), are closed.
检查阀门（02G和02D）及泄压阀（03G 和03D）确保关闭。
In the case where the outlet pressure regulator option is used, check that the relief screw is unscrewed.
如果出口减压阀被选用时，检查泄压螺钉，应处于未拧紧状态。
1st phase: Bleeding of hoses第一阶段：泄压软管
a) Bleeding of the right-hand side: 右边泻压
Successively bleed all hoses by carrying out at least three compression-relief cycles, i.e.
连续执行至少三次压缩和释放循环，实现所有的软管泻压。
Open the cylinder valves.
打开钢瓶阀门。
The pressure is indicated on HP pressure gauge (05D).
压力显示在HP压力表(05D)上。
Close the cylinder valve.
关闭钢瓶阀门。
Open bleed valve (03D).
打开泄压阀(03D)。
Close the bleed valve when H.P. pressure gauge (05D) gives a reading of 0.
当HP压力表(05D)显示值为0时，关闭泄压阀。
Repeat this operation at least twice.
重复以上操作至少两次。
b) Bleeding of the left-hand side: 左边泄压
Same operation as in a), using the valves which correspond to the left-hand side.
操作同a），用与左边相对应的阀门。
2nd phase: Operational check第二阶段：操作检查
Initial state:初始状态：
-cylinder valves closed.钢瓶阀门关闭
-inlet valves closed.入口阀门关闭
-bleed valves closed.泄压阀门关闭
⏹ Open the cylinder valves of each of the sources.
打开每个气源的钢瓶阀门。
⏹ Slowly open inlet valve (02G) or (02D) (whichever side is chosen as the source).
缓慢打开入口阀门(02G) 或 (02D)（作为气源的一端）。
⏹ Make a note of the operating pressure indicated on LP pressure gauge (06).
记录下显示在LP压力表(06)的操作压力。
⏹ Slowly open inlet valve (02G) or (02D) (whichever side is chosen as the reserve).
缓慢打开入口阀门(02G) 或 (02D)（作为备用气源的一端）。
⏹ Allow gas to flow through the changeover manifold, and bleed all the pipes.
允许气体流经切换面板，置换所有的管道。
⏹ If an outlet pressure regulator is used, do not to get to screw in the relief screw.
如果使用了出口减压阀，不要拧紧释放螺钉。
3rd phase: Automatic switch-over check第三阶段：自动切换检查
Close the cylinder valve of the source in service; the indication decreases on the high pressure gauge of the source in service.
关闭供气端的钢瓶阀门，供气端的高压表显示值将减小。
When this pressure has dropped to approximately P2-20%, the reserve source should come into service.
当压力减少到大约P2-20%时，备用气源将投入使用。
Change the position of the lever, the initial pressure of P2 is restored.
改变操纵杆的位置，重新建立P2的初始压力。。
This operation can be repeated in reverse order; this will check the automatic
operational switch-over in both directions.
此操作可以在相反方向重复，用以检查两个方向的自动切换操作。
The changeover manifold has now been tested and is ready to operate.
至此切换面板测试完毕可投入运行。
Open the operating valve. Gas flows from the changeover manifold at the required pressure, and the source in service is the one defined by the position of the lever.
打开操作阀门。气体按照所需压力从切换面板流出，工作气源由操纵杆的位置决定。
When the source in service becomes depleted, the changeover manifold will automatically switch to the reserve source. When replacing the depleted cylinders, it will simply be necessary to change the position of the lever so that the source which was originally in reserve is put into service and that the full cylinders are used as the reserve source.
当工作气源将用尽时，切换面板会自动切换到备用气源。更换空钢瓶时，需要改变操纵杆的位置，这样最初作为备用气源的气体投入使用，更换上的满钢瓶被作为备用气源。
