WBFA： TPC A 编码器故障

断开 TPC 的电源并等待 5 分钟。

在 TPC 中，验证马达电缆上的连接器是否固定在 PCB 上的插座上。 验证电线套圈是否固定在连接器中。

验证马达内部的编码器连接器是否正确配对。

注： 只有在开机时才具备检查此错误的条件。  要复位然后重新检查此错误，请重启整个 Reactor 系统的电源。

断开 TPC 的电源并等待 5 分钟。

验证编码器杆是否正确安装到马达轴上。

验证编码器安装卡舌是否正确固定在马达上。

断开 TPC 的电源并等待 5 分钟。

断开马达电缆与 TPC 和马达的连接。  检查电缆两端之间所有编码器信号的连续性。

更换编码器。

The encoder calibration procedure will activate after one of the following events occurs and the transfer pump is turned on:

 - A new TPC is first connected to a Reactor system

 - A transfer pump configuration has been changed from "Air" to "Electric" within the setup screen

 - The transfer pump calibration button has been pressed within the setup screen

 - A calibration had been previously attempted but failed (resulted in a WBFA or WBFB alarm)

The transfer pump encoder calibration procedure can fail if the procedure is interrupted by another alarm or if the pump is not able to freely move during the calibration procedure. When a pump fails to calibrate properly, the pump will automatically try to calibrate again the next time the pump is turned on.

If the calibration procedure was interrupted by a different alarm, address the cause of that issue and try again.

If the pump is unable to move adequately, create a low back pressure fluid path for the pump. The preferred method is to open the recirculation valves to allow fluid to flow back into the drum or waste pail. Enable the transfer pumps via transfer pump jog mode at a slow jog speed, or alternatively, enable the entire system via pressure mode. The transfer pumps can also be calibrated by starting the entire system in pressure mode with the recirculation valves closed, however, it may take several attempts for this method to be successful.
