1、使用测电笔或者万用表检查三相电源是否正常有无缺相或电压异常，确认正常后合上电源总开。

1, the test pencil or a multimeter to check whether there is no normal three-phase power phase or abnormal voltage, confirm the normal close power drive.

2、选择使用机组1或2，检查相应电控箱面板上开关是否处于自动状态，然后打开控制箱合上相应机组空开供电，相应的另一台机组电控箱医药冷库内电源必须处于断开状态以防两台机组同时工作超出电源供电线路负荷。

2, choose to use 1 or 2 units, whether in automatic mode switch check panel corresponding electric control box, and then open the control box on the corresponding unit air supply, another unit electric control box power corresponding must be disconnected to prevent two units at work beyond the power supply line load.

3、合上控制箱内空开后关上控制箱门查看控制箱面板电源指示灯是否正常点亮，并观察数显温控与温度记录仪显示温度是否一致(相差0.5℃以内为正常)。

3, on the control box open closed control box door check control box panel power indicator light is normal, and the observation of digital temperature control and temperature recorder display temperature is consistent (up to 0.5 DEG C for normal).

4、对照电控箱说明书调整数显温控，设置参数为：上限温度为7℃，下限温度为3℃，超温报警值为1，超温报警延时为0，机组开机延时为3分钟。

4. Adjust the digital display temperature control with the instruction of the electronic control box, set the parameters as follows: the upper limit temperature is 7 degrees, the lower limit temperature is 3 degrees, the overtemperature alarm value is 1, the overtemperature alarm delay is 0, the unit startup delay is 3 minutes.

二 温度记录仪设置及操作

Setting and operation of two temperature recorder

1、温度记录仪记录间隔为15分钟，上限为8℃下限为2℃，按键停止设置为禁止。

1, the temperature recorder recording interval is 15 minutes, the upper limit is 8 degrees, the lower limit is 2 degrees, the button is set to prohibit.

2、温度记录仪记录容量为16000次，相对应每次间隔15分钟总记录时长为166天，所以每间隔165天必须把记录仪连接电脑把储存器内数据导入硬盘保存，保存后需重新设置一次以清除原来记录仪内储存器上的数据，重新设置后需重新按住记录仪上按键5秒以上开启记录仪。(具体见记录仪说明书)

2, temperature recorder capacity is 16000 times, corresponding to the time interval of 15 minutes total record length of 166 days, so every 165 days to put the recorder connected to the computer in the memory data into hard disk storage, save to reset once to remove the original recorder in storage device on the data, after the reset the need to hold the recorder button for 5 seconds on recorder. (see the recorder instructions)
