CM210/CM215型投影機(jī)電動(dòng)升降吊架（以下簡(jiǎn)稱吊架）是最新出的新產(chǎn)品。桿式式結(jié)構(gòu)。它有款式新穎，工作可靠，安裝和調(diào)試簡(jiǎn)易，運(yùn)行可靠，定位準(zhǔn)確，升降運(yùn)行時(shí)噪音十分低、行程大、操作容易、外形美觀大方等特點(diǎn)，是精密投影機(jī)的優(yōu)良輔助設(shè)備。

投影機(jī)不使用時(shí)，吊到裝飾天花板上。使用時(shí)只須操作按鈕就可以把投影機(jī)吊放下來(lái)，用完以后，稍操作按鈕，又可將投影機(jī)吊裝回天花板上，不但對(duì)投影機(jī)有良好的保護(hù)作用，又騰出投影機(jī)所占用的空間，另作別用，靈活地?cái)U(kuò)充了室內(nèi)空間的使用效率，可說(shuō)是投影機(jī)必備的良好配套設(shè)備。

☆技術(shù)參數(shù)：

1、 行程范圍：1米/1.5米

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

3、 凈 重：20KG

4、 承吊重量：20KG

☆配送附件：

1、 投影機(jī)接口底盤一個(gè)。用于連接固定投影機(jī)。

●注：接口盤+萬(wàn)向頭高度：80㎜～130㎜（不同投影機(jī)接口盤高度不同）

安裝及調(diào)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(jī)身高度+接口盤高度+萬(wàn)向頭高度+投影機(jī)實(shí)際厚度）特殊情況除外

2、 建議天花開口：380㎜×380㎜（視投影機(jī)大小而定）

3、必須預(yù)留維修口，建議在離吊架100㎜～200㎜處口：400㎜×400㎜

4、通過(guò)吊架頂上的四個(gè)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(shí)，首先選好位置，根據(jù)投影機(jī)所處的位置確定吊架所處的方向，必須準(zhǔn)確定好四個(gè)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(fēng)管及中央空調(diào)風(fēng)口等發(fā)熱設(shè)備。

5、供電電源應(yīng)設(shè)有雙閘刀電源開關(guān)，并裝有4A的熔斷管，電源線和控制線應(yīng)用橫截面積不小1.5mm2的銅芯線。電源開關(guān)和操作按鈕應(yīng)盡量靠近吊架，并使操作按鈕時(shí)能直接看到吊架的運(yùn)行情況，吊架機(jī)殼還應(yīng)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(rèn)。

6、安裝步驟見(jiàn)附圖一：

7、行程調(diào)節(jié)見(jiàn)附圖二：

擰松上限位行程開關(guān)的兩個(gè)緊固螺釘即可移動(dòng)上限位行程開關(guān)調(diào)整上限位，同理也可調(diào)整下限位。

● 注1：調(diào)整好上、下限位后一定要擰緊其緊固螺釘，否則吊架在運(yùn)行過(guò)程中會(huì)發(fā)生定位不準(zhǔn)的情況。

● 注2：行程開關(guān)可斜對(duì)拆掉各一個(gè)，可減短上、下定位距離。

8、電氣控制原理見(jiàn)附圖三：

注意事項(xiàng)：

安裝時(shí)，吊頂膨脹螺栓必須牢固，吊架升降運(yùn)行時(shí)，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(shí)，因吊架下面有桌子等東邊把吊架承托住，就會(huì)使吊架的鋼絲繩松脫或混亂，容易產(chǎn)生事故；被吊物品應(yīng)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(yùn)行。吊架運(yùn)行時(shí)，注意手或其它物體不可伸進(jìn)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(wú)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(yīng)檢查有無(wú)短路現(xiàn)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(dòng)，否則本公司概不負(fù)責(zé)保修，一切責(zé)任自負(fù)。

故障及排除：

新安裝的或者以使用有相當(dāng)時(shí)日的VM40投影機(jī)吊架，發(fā)生故障，需要自行檢查時(shí)，應(yīng)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(fù)責(zé)保修。檢查時(shí)，首先檢查接地保護(hù)是否可靠，防止觸電事故。

全不動(dòng)，毫無(wú)反應(yīng)。

1、 檢查電源上終端進(jìn)線、端子是否有電，電壓是否正常。如果沒(méi)有電則應(yīng)檢查供電線路。

2、 如果電源進(jìn)線端子電壓正?？蓹z查按鈕連線，電動(dòng)機(jī)連接線有無(wú)松脫，熔斷器有無(wú)燒斷，檢查上終端和下終端行程開關(guān)接線有無(wú)松脫。

3、 升降架處于上終端，上終端行程開關(guān)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(guān)被壓住升降架不能下行，都屬于正?，F(xiàn)象。

按上行或下行按鈕都不能運(yùn)行，但聽到振動(dòng)的聲音，且聲音比較弱。

應(yīng)檢查電容器是否被擊穿、短路及其連線是否脫落、斷路。這時(shí)電機(jī)會(huì)嚴(yán)重發(fā)熱，應(yīng)立即斷開電源，以免燒壞電機(jī)。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(dòng)，但機(jī)器內(nèi)發(fā)出較大噪聲。

1 檢查傳動(dòng)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(cuò)位。

3 檢查齒輪與軸之間的鎖緊螺絲是否松動(dòng)，使軸不能帶著齒輪旋轉(zhuǎn)。

上升、下降時(shí)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(nèi)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。

The power switch and the control cutton should ce placed close to the lift as possicle, and the operator should see the movement of the lift directly when control it. The casement of the lift must touch the ground with stacility. The resistance of the grounded wire shouldn’t over 4 ＆#911;, and the core should ce of copper and its transect shouldn’t ce smaller than 1.5mm2. And the grounded wire should ce in other color for easy discrimination.

6. Please refer to the attached drawing 1 for installation

7. Please refer to the attached drawing 2 for distance adjustment:

The upper limit can ce adjusted after cy loosening the two fixed colts on the upper-limit switch, which may make the upper-limit switch moved. The same as adjusting the lower limit.

Attn: The fixed colts must ce tightened enough after adjusting the upper and lower limits, or the orientation may not exact in the operating process of the lift.

8. Please refer to the attached drawing 3 for electric control

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
