BENTLY 60M100-00監(jiān)測(cè)器卡件,60M100-00中文說明
本節(jié)提供了有關(guān)的故障排除信息
液壓伺服（HSS）模塊。這些信息包括診斷測(cè)試、報(bào)警和異常報(bào)告、問題報(bào)告和故障排除流程圖。有助于故障排除的其他參考文件包括處理器模塊、操作員界面（即。，OIS、EWS等）和功能代碼應(yīng)用手冊(cè)。而下部觸點(diǎn)關(guān)閉閥門。使用4到20毫安的位置輸出來確定閥門位置。
4、要返回自動(dòng)模式，MFP模塊必須與HSS模塊通信。If硬手動(dòng)模式通過功能代碼55選擇，規(guī)范S13必須返回自動(dòng)模式，<S13>=0。最后，操作員必須與D/A轉(zhuǎn)換器輸出值（塊編號(hào)）匹配N+1）和來自MFP模塊的當(dāng)前位置需求。
BENTLY 60M100-00監(jiān)測(cè)器卡件注意：如果HSS模塊通過與MFP模塊失去通信而進(jìn)入硬手動(dòng)模式，則當(dāng)MFP模塊與建立通信時(shí)，HSS模塊將退出硬手動(dòng)模式HSS模塊，以及當(dāng)MFP和HSS模塊匹配。MFP模塊從手動(dòng)操作期間保持的閥位恢復(fù)自動(dòng)操作。汽輪機(jī)跳閘汽輪機(jī)跳閘通過提供以下方式實(shí)現(xiàn)快速停機(jī)：驅(qū)動(dòng)節(jié)氣門關(guān)閉。跳閘偏置電路超越來自HSS微處理器的位置控制，并驅(qū)動(dòng)閥門關(guān)閉。要驅(qū)動(dòng)閥門關(guān)閉，請(qǐng)關(guān)閉跳閘偏置開關(guān)（客戶安裝）將24 VDC應(yīng)用于跳閘偏置數(shù)字輸入
This section provides troubleshooting information for the
hydraulic servo (HSS) module. This information includes diagnostic testing, alarm and exception reporting, problem reports
and troubleshooting flowcharts. Additional reference documents that are helpful for troubleshooting are product instructions for the processor module, the operator interface (i.e.,
OIS, EWS, etc.) and the Function Code Application Manual.while the lower contact closes the valve. Use the 4 to 20 milliamp position output to determine the valve position.
4. To return to automatic mode, the MFP module must be
communicating with the HSS module. If hard manual mode
was selected through function code 55, specification S13 must
be returned to auto mode, <S13> = 0. Finally, the operator
must match the D/A converter output value (block number
N+1) with the current position demand from the MFP module.
NOTE: If the HSS module enters hard manual mode by losing communication to the MFP module, the HSS module will exit hard manual mode when the MFP module establishes communication with
the HSS module, and when position demands from the MFP and
HSS modules match. The MFP module resumes automatic operation from the valve position held during manual operation.
TURBINE TRIP
Turbine trip provides quick shutdown by providing a way to
drive the throttle valve closed. The trip bias circuit overrides
position control from the HSS microprocessor and drives the
valve closed. To drive the valve closed, close the trip bias switch
(customer installed) to apply 24 VDC to the trip bias digital
input.
