2测试台运转前准备工作的安全须知
检查设备现状和完好状态,检查各管路的压力表,按钮在运输过程中是否损坏,当测试台发现故障和液压系统出现异常噪音时,要切断电源停止工作,排除故障,严禁测试超出试压范围的阀门.
3.有关电器方面的安全须知
测试台采用三相四线,交流电源：电压380v,50Hz,控制电路电压220v,50HZ:非专业工作人员禁止触及电力控制装置以免危险.由于测试台按钮较多,因此提醒操作人员必须对安全问题高度重视,未经过学习本须知,严禁上岗.
检查电源接地线是否可靠,线径是否符合要求.
检查电源相续是否正确.
检查信号指示是否正确.
测试台电器出现故障时,应首先关闭电源,故障不解除,任何人不准送电.
电器维修人员必须按电工操作规程穿电工绝缘工具进行工作,维修期间必须有专人看管,或在电源处挂牌警示

2 one before running for safety guidelines
Check the equipment status and good condition, check the pipeline pressure gauge, button in the course of transportation is damaged, when one found fault and hydraulic system appears unusual noise, cut off the power supply to stop working and remove the faults, forbidden beyond the scope of the valve pressure test.
3. The electrical safety instructions
One three-phase four-wire, ac power: voltage 380 v, 50 Hz ac, control circuit voltage 220 v, 50 Hz ac: non-professional workers banned power control device to avoid dangerous touch. Because one more button, so remind the operators must attach great importance to the problem of security, not after learning the notes, it is strictly prohibited to mount guard.
Check the power supply is reliable grounding line, line diameter meets the requirements.
Check the power supply sequential is correct.
Check signal instructions is correct.
One, electrical malfunction, should first shut off the power and fault not relieved, and no one is allowed either.
Electrical maintenance personnel must be electrician operating rules wear electrician tools for insulation, there must be a special person to care about maintenance period, or in the power source for warning
