解决方法
Solutions

1. 确认主机 PC 到仪器的所有网络硬件都已正确连接且已接通电源 Make sure that all network hardware from the host PC to the instrument is properly connected and powered on

2. 直接用交叉电缆连接主机 PC 与 EPC，不使用任何 LC 或网络硬件。 Connect host PC and EPC directly with cross cable, without any LC or network hardware

3. 退出 MassLynx 并重新启动计算机或在使用 UNIFI 控制时，让仪器系统离线。 Quit MassLynx and restart your computer or take the instrument system offline while using UNIFI control

4. 将 Xevo 系列仪器背面的泵手动控制开关（顶部开关）向下拨动，切换至手动控制位置，对于 Synapt 系列仪器，向右拨动泵手动控制开关以切换至手动控制位置。对于 QToF Prem，向下拨动泵手动控制开关以切换至手动控制位置。 Turn the pump manual control switch -LRB-top switch) on the back of XEVOXevo series instrument down to the manual control position, and for SYNAPTnapt series instrument, turn the pump manual control switch to the right to switch to the manual control position. For QToF Prem, flip the pump manual control switch down to switch to the manual control position

5. 关闭 Xevo 系列的电子电路开关，对于 Synapt 系列和 QToF Prem，EPC 和电子电路开关都必须关闭。 Turn off XEVO series electronic circuit switches. For Synapt series and QToF Prem, EPC and electronic circuit switches must be turned off

6. 关闭 Xevo ToF/QtoF G2 的外部 EPC 电源（注意：直接关闭电源最有效的方式是使用 EPC 背面的电源开关） Turn off the external EPC power on the Xevo Tof/QtoF g 2(Note: the most effective way to turn off the power directly is to use the power switch on the back of the EPC)

7. 等待 2 分钟。然后，将 Xevo 系列仪器上的电子电路开关切换至 ON（开，向上）位置，对于 Synapt 系列仪器，打开 EPC 和电子电路开关。 Wait 2 minutes. Then, switch the electronic circuit switch ON the XEVO series to the ON (ON, up) position, and for the SYNAPT series, turn ON the EPC and electronic circuit switch

8. 将外部 EPC 背面的电源开关切换至 ON（开）位置。 Switch the power switch ON the back of the external EPC to the ON position

9. 等待 2-3 分钟，让系统建立通讯。 Wait 2-3 minutes for the system to establish communication

10. 在桌面上的“运行”窗口中，键入“ping -t epc”，确保 epc 可以正常通讯。 In the run window on your desktop, Type ping-t EPC to ensure that the EPC is communicating properly

11. 打开 Tune 页面（或 UNIFI 中的仪器控制台），此时应显示一条红色警告信息，提示泵手动控制已生效 Open the Tune page (or the instrument console in UNIFI-RRB- with a red warning message indicating that the manual pump control is in effect

12. 将泵手动控制开关向上切换回 Control/Auto（控制自动）（在 Synapt 系列仪器上应向左切换）。 Switch Pump Manual Control switch up back to Control/Auto (Control Auto)(switch left on SYNAPT series instruments)

附加信息
Additional information
电源模块 PCB 故障导致仪器电子设备断电。而 EPC 由配电装置直接供电，通过电子电路开关和 EPC 开关进行控制。其结果就是发送至 EPC 的通讯正常，但没有 EPC 到仪器电子设备（透镜控制 PCB）的通讯。请参阅电源模块技术参考文件了解预期电压输出。
PCB failure of power supply module leads to power failure of instrument and electronic equipment. The EPC is directly powered by the power distribution device and controlled by electronic circuit switches and EPC switches. As a result, communication to the EPC is normal, but there is no communication from the EPC to the instrument electronics (lens-controlled PCB) . Please refer to the power module technology reference file for the expected voltage output.
