电子超载保护器 EF370说明书
—PRO DUC T EN V I RO N M ENTA L I N FO R M ATI O NElectronic overload relays EF370The EF370 is a self-supplied electronic overload relay, which means no extra external supply is needed. They are offering reliable and fast protection for motors in the event of overload or phase failure.EF370 electronic overload relays are available from 115 A up to 380 A. They are easy to use like thermal overload relays and compatible with standard motor applications. Electronic overload relays are convincing, above all, due to their wide settingrange, high accuracy, high operational temperature range and the option to select a trip class (10E, 20E, 30E). Further features include temperature compen-sation, trip contact (NC), signal contact (NO), auto-matic- or manual reset selectable, trip-free mecha-nism, STOP- and test function and a trip indication. The overload relays can connect directly to AF block contactors. Single mounting kits are available as ac-cessory. The EF370 electronic overload relays have ATEX and IECEx certification.Product conformity & complianceREACH (Regulation EC 1907/2006)EF370 and related accessories were classified as articles and, during normal and reasonablyforeseeable conditions of use, do not intentionally release any substance or preparation.ABB continuously undertakes communications throughout its supply chain in order to collect information about suppliers’ compliance with REACH regulation.SVHC (Regulation EC 1907/2006 REACH)ABB continuously assesses its products for content of Substances of Very High Concern (SVHC), as included in the “Candidate List” by the European Chemicals Agency (ECHA).

修
当仪器在调试或使用过程中出现故障时，可按以下步骤进行一般检查： 检查连线是否松动、断线或短路。 检查保险丝是否烧断。 检查电源电压是否符合要求。 检查机械安装是否合理。 检查传感器是否正常。 检查零点和量程，可参照（5. 调试、校准） 仪器发生较大故障时可送回生产厂家修理。
5． 调试、校准
先把仪表后面板上的 6 颗螺钉拧开，将仪表前面板拉出至内部两层线路板都能看见的位置。 仪器通电 20 分钟后，就可进行调试、校准。 注意：调试、校准时必须将门机的减速箱手柄放到慢速位置，并将幅度收到 20 米以内，用 最小幅度的额定起重量校准满量程！ 5.1 调整零点 卸去吊钩上的所有重物，并使钩头离地 1 米左右，参照图三，用万用表测量（后层）主板上 检测点KVO2与COM两端的输出电压，调整主板上的电位器W5，使输出电压为零。 5.2 调整量程 吊起满量程的砝码，将主板上的W1电位器调到中间位置，逐个改变SE1，SE2，SE4，SE8四个 插头的短接套位置， （插向ON位置，输出电压减小，插向OFF位置，输出电压增大，SE8的改变量 ）粗调量程，使输出电压最接近满量程（2.000V） 。 最大，SE1的改变量最小。 细调W1电位器，使输出电压达到满量程（2.000V） 。 卸下砝码，重新按 5.１条 调零。然后再吊起满量程砝码，按 5.2 条 重调满量程。重复几 次以上步骤，使起重机在空载时，输出电压为零。在满载时，输出电压为 2.000V。 5.3 调整显示 吊起满量程的砝码，参照图四，调整前层显示板上的电位器W1，使面板显示值与实际负荷值 一致。 （例 1： 满负荷为 40t，则将显示值调到 40.0。例 2：满负荷为 25t，则将显示值调到 25.0。 例 3：满负荷为 20t，则将显示值调到 20.0，不要调到 20.00，否则重量超过满量程时，显示器将 熄灭。 ） 经过以上调整，PCI－1002B 超载限制器的调试、校准工作已全部结束，将前面板推入仪表 外壳，拧紧后面板上的 6 个螺钉后，PCI－1002B 超载限制器就可投入正常工作。 5 2
