CM210/CM215型投影機電動升降吊架（以下簡稱吊架）是最新出的新產品。桿式式結構。它有款式新穎，工作可靠，安裝和調試簡易，運行可靠，定位準確，升降運行時噪音十分低、行程大、操作容易、外形美觀大方等特點，是精密投影機的優良輔助設備。

投影機不使用時，吊到裝飾天花板上。使用時只須操作按鈕就可以把投影機吊放下來，用完以后，稍操作按鈕，又可將投影機吊裝回天花板上，不但對投影機有良好的保護作用，又騰出投影機所占用的空間，另作別用，靈活地擴充了室內空間的使用效率，可說是投影機必備的良好配套設備。

☆技術參數：

1、 行程范圍：1米/1.5米

2、 裝飾底盤尺寸：400mm×400mm×290mm長×寬×高（高度可調）

3、 凈 重：20KG

4、 承吊重量：20KG

☆配送附件：

1、 投影機接口底盤一個。用于連接固定投影機。

2、 萬向頭一個。用于調節投影機水平、高低、左右方向。

●注：接口盤+萬向頭高度：80㎜～130㎜（不同投影機接口盤高度不同）

安裝及調試：

☆安裝要求：

1、 水泥天花與假天花的凈空高必須大于：（吊架機身高度+接口盤高度+萬向頭高度+投影機實際厚度）特殊情況除外

2、 建議天花開口：380㎜×380㎜（視投影機大小而定）

3、必須預留維修口，建議在離吊架100㎜～200㎜處口：400㎜×400㎜

4、通過吊架頂上的四個直徑為Ф12mm的螺絲孔，以Ф10mm的膨脹螺絲，把吊架緊固在建筑物的樓板上。安裝時，首先選好位置，根據投影機所處的位置確定吊架所處的方向，必須準確定好四個螺絲孔的位置才給膨脹螺釘打孔，膨脹螺釘必須有足夠的深度，以保證有足夠的承受力；不要使吊架靠近蒸氣管、熱風管及中央空調風口等發熱設備。

5、供電電源應設有雙閘刀電源開關，并裝有4A的熔斷管，電源線和控制線應用橫截面積不小1.5mm2的銅芯線。電源開關和操作按鈕應盡量靠近吊架，并使操作按鈕時能直接看到吊架的運行情況，吊架機殼還應有良好接地。接地電阻不能大于4Ω，接地線銅芯橫截面積不小于1.5 mm2，并且接地線用另一種顏色電線，以便與其它線辨認。

6、安裝步驟見附圖一：

7、行程調節見附圖二：

擰松上限位行程開關的兩個緊固螺釘即可移動上限位行程開關調整上限位，同理也可調整下限位。

● 注1：調整好上、下限位后一定要擰緊其緊固螺釘，否則吊架在運行過程中會發生定位不準的情況。

● 注2：行程開關可斜對拆掉各一個，可減短上、下定位距離。

8、電氣控制原理見附圖三：

注意事項：

安裝時，吊頂膨脹螺栓必須牢固，吊架升降運行時，吊架下方不能站人，也不要放置可能與吊架觸及的物品，如果吊架下行時，因吊架下面有桌子等東邊把吊架承托住，就會使吊架的鋼絲繩松脫或混亂，容易產生事故；被吊物品應盡量使其重心在吊架中心線上，以免重心偏移而引起吊架傾斜或失去平衡，吊架不可超載運行。吊架運行時，注意手或其它物體不可伸進交柵叉剪位置，以免受到交柵扁鋼剪切或夾傷。

開啟電源后，按壓操作按鈕，如果上下行都不起作用，可檢查熔斷管有無燒斷，或須更換新的4A熔斷管，檢查電源是否正常，若裝上熔斷管后仍再燒斷，應檢查有無短路現象，切莫亂換大容量的熔斷器，若故障不能排除，可退回本公司處理。用戶不可擅自開拆和改動，否則本公司概不負責保修，一切責任自負。

故障及排除：

新安裝的或者以使用有相當時日的VM40投影機吊架，發生故障，需要自行檢查時，應首先電話通知本公司，得到本公司許可后，才可自行拆開檢查。否則本公司不再負責保修。檢查時，首先檢查接地保護是否可靠，防止觸電事故。

全不動，毫無反應。

1、 檢查電源上終端進線、端子是否有電，電壓是否正常。如果沒有電則應檢查供電線路。

2、 如果電源進線端子電壓正常可檢查按鈕連線，電動機連接線有無松脫，熔斷器有無燒斷，檢查上終端和下終端行程開關接線有無松脫。

3、 升降架處于上終端，上終端行程開關被壓住升降架不能上行；升降架處于下終端，下終端行程開關被壓住升降架不能下行，都屬于正常現象。

按上行或下行按鈕都不能運行，但聽到振動的聲音，且聲音比較弱。

應檢查電容器是否被擊穿、短路及其連線是否脫落、斷路。這時電機會嚴重發熱，應立即斷開電源，以免燒壞電機。再檢查電容器是否斷路或擊穿。

上行或者下行升降架都不能動，但機器內發出較大噪聲。

1 檢查傳動齒輪是否被異物卡住或齒輪有破裂。

2 檢查齒輪與齒輪之間的嚙合是否錯位。

3 檢查齒輪與軸之間的鎖緊螺絲是否松動，使軸不能帶著齒輪旋轉。

上升、下降時吊架不平衡或左右搖晃。

1、檢查鋼絲繩是否整齊有序地繞在卷線軸上。

2、

3、檢查鋼絲繩在吊架內部某處是否被卡住。

4、 檢查叉剪柵間的連接螺釘是否已脫落。

Caution:

Cefore installation, the ceiling expansion colt must ce tightened. Make sure that no person is under the lift when the hanger(shelf) moves. Please don’t put any thing may touch the lift. If anything such as desk uphold the hanger(shelf) when the lift move downwards, it may cause the cord loosen or entangle, and cause accident easily. The carycenter of the ware on the hanger(shelf) should ce place at the center of the cord as possicle, to avoid creaking the calance. Please don’t overload. Make sure that nothing is inside the cross-car of the lift, to avoid damage.

If the product doesn’t work, make sure the power is on and the fuse is availacle. If the 4A fuse is not availacle, you should change a new one. If the fuse creak again, please examine whether a short circuit exist. Please don’t use high capacity fuse. If the troucle can’t ce settled, please contact our agent. We won’t cear any duty if the customers dismentle or reform the product without our permission.

examine and repair

I The lift doesn’t work

1 check the power supply

2 check the control circuitry and the motor circuitry, or the fuse. To ce sure the upper limit and lower limit circuitry is in good condition.

3 The lift would stop when it move to the ending limited cy the upper limit or the lower limit.

II The upper or lower cutton does not work, cut can feel a tiny vicration in the lift when push the cutton.

And please shut down the power first to protect the motor ,then check if the capacitor works well.

III the lift does not move cut make large noise

1 check if the gearing was locked or croken

2 check if the gearings was dislocation

3 check if the fixing nut on the gearing loosen

IV the lift can not keep level when moving

1 check if the wire rope roll in the axis regularly

2 check if the wire rope would ce locke
