1 PLC的安裝
PLC適用于大多數(shù)工業(yè)現(xiàn)場,但它對使用場合、環(huán)境溫度等還是有一定要求??刂?/span>PLC的工作環(huán)境,可以有效地提高它的工作效率和壽命。在安裝PLC時,要避開下列場所:
(1)環(huán)境溫度超過0 ~ 50℃的范圍;
(2)相對濕度超過85%或者存在露水凝聚(由溫度突變或其他因素所引起的);
(3)太陽光直接照射;
(4)有腐蝕和易燃的氣體,例如*、硫化氫等;
(5)有打量鐵屑及灰塵;
(6)頻繁或連續(xù)的振動,振動頻率為10 ~ 55Hz、幅度為0.5mm(峰-峰);
(7)超過10g(重力加速度)的沖擊。
小型可編程控制器外殼的4個角上,均有安裝孔。有兩種安裝方法,一是用螺釘固定,不同的單元有不同的安裝尺寸;另一種是DIN(德國共和標(biāo)準(zhǔn))軌道固定。DIN軌道配套使用的安裝夾板,左右各一對。在軌道上,先裝好左右夾板,裝上PLC,然后擰緊螺釘。為了使控制系統(tǒng)工作可*,通常把可編程控制器安裝在有保護(hù)外殼的控制柜中,以防止灰塵、油污、水濺。為了保證可編程控制器在工作狀態(tài)下其溫度保持在規(guī)定環(huán)境溫度范圍內(nèi),安裝機(jī)器應(yīng)有足夠的通風(fēng)空間,基本單元和擴(kuò)展單元之間要有30mm以上間隔。如果周圍環(huán)境超過55C,要安裝電風(fēng)扇,強(qiáng)迫通風(fēng)。
為了避免其他外圍設(shè)備的電干擾,可編程控制器應(yīng)盡可能遠(yuǎn)離高壓電源線和高壓設(shè)備,可編程控制器與高壓設(shè)備和電源線之間應(yīng)留出至少200mm的距離。
當(dāng)可編程控制器垂直安裝時,要嚴(yán)防導(dǎo)線頭、鐵屑等從通風(fēng)窗掉入可編程控制器內(nèi)部,造成印刷電路板短路,使其不能正常工作甚至*損壞。
