1、联动台应用安装螺钉固定。
2、按照电气原理图的要求,分别逐档操作联动台,观察触头的分合是否与触头分合程序表相符,如有不符,应予以调整或更换凸轮片。
3、在通电前必须检查电动机、电阻器和控制屏等有关电气了系统的接线是否正确,接地是否可靠。对于主令式联动台在通电前应将控制屏主开关断开,只操纵控制回路,来观察和各种触器的运行程序是否正确。
4、通电后应按相应凸轮控制器和控制屏说明书细心检查电动机运行情况,若有差异应立即切断电源,待查明原因后方可继续通电。
5、联动台应按以下经常检查维修:
1)所有螺钉联接部分必须紧固,特别是触头接线螺钉;
2)磨擦部分应经常保持一定的润滑;
3)触头工作表面应无明显的熔斑,烧熔的部位可用细锉刀精心修理,不允许使用砂纸。对于10安直流触头组在更换触头时,磁钢必须按以下极性装配;
4)损坏的零件极时更换。
根据用户要求,联动台可以组成多种不同的形式。如表1所列联动台符合使用要求时,只须写明产品型号即可订货。否则需对以下几项提出要求:
1、对于手柄所控机构和触头分合程序的要求:
联动台有多个操纵机构,一般分为左纵机构、左横机构、右纵机构、右横机构、左后机构、右后机构等。订货时须指明机构的用途以及相应的触头分合程序(包括控制档位,触头元件序号见表2),对采用表3中的标准控制线路时须写明控制器(屏)型号。若选表4中的分合程序时只写明编号即可。
2、对触头容量等级的要求:除采用标准凸轮控制器和控制屏线路外,若选用其他线路时,须提出触头容量等级或所控电动机容量。如不供上述要求时,则均按控制线中选择交流380伏,10安触头(控制回路为直流时必须注明)。
3、对附件的要求:
如用户对附件无特殊要求,一般常按图8带附件和接线。若上述规格数量不能满足要求时,用户对所需附件提出型号,数量和用途的要求。需要安装仪表和其他较大型元件时,可选用6型控制箱。
4、对控制箱型式的要求:
控制箱型式共有6种,选用1型---3型控制箱时仅说明前三条即可,不必再指箱型。如选用4型---6型非标准控制相时,均需指出控制箱型式。
