静态调试步骤：
A. 汽轮机静态拉阀试验：
首先，开交流润滑油泵和高压油泵。将手拍危急遮断器拉出，然后手拉挂闸装置手柄保持一段时间，使安全油建立，主汽门能缓慢打开。（也可以在DEH画面中点击远方挂闸使挂闸电磁铁带电开启主汽门）
然后，拔掉DDV阀插头，旋转DDV阀块上的手调节流孔使油动机能打开或关闭（顺时针旋转油动机打开，逆时针旋转油动机关闭）。调节节流孔在油动机全关时调节伺服卡上的“显示调零”电位器使数码管显示为零，然后调节输出调零电位器,使VO1为0V；VO2为0V；调节节流孔在油动机全开时调节伺服卡上的“显示调满”电位器使数码管显示为120，然后调节输出调满电位器,硅片切割
使VO1为100mV；VO2为5V；然后调整手调节流孔使油动机缓慢向关闭方向移动，这时锁紧节流孔锁紧螺母（即此时为阀心位置，可暂时不锁紧，不要再调整手调节流孔）。
接着，插上DDV阀插头，在VBTA-12DEH拉阀试验（即阀门标定试验，点标定投入）画面中，指令给定0％时，调节伺服卡上的“反馈调零”电位器使数码管显示为零。指令给定100％时，调节伺服卡上的“反馈调满”电位器使数码管显示为120。（可能一次不能够调到0%，或者100%，需要来回调0%和100%多次方可）
B.OPC开关量调试：
1, 将端子DI+/DI-短接
2, 判断端子AO+/AO-的输出电流极性是否满足要求。如与要求的电流极性相反，则将跳线器S2-1 ,S2-2b型钢重新设置（出厂设置为电流由AO+流向AO-））
S2-1: ON;S2-2:OFF,则伺服输出AO+/AO-电流输出为负(电流由AO-流向AO+)
S2-1: OFF;S2-2:ON,则伺服输出AO+/AO-电流输出为正(电流由AO+流向AO-)（出厂默认设置）
C，颤振的调试
锚杆测力计
1，在端子AO+/AO-接60欧姆左右的电阻
2, 位移传感器滑杆调至零刻度，同时在AI输入4 mA,此时伺服输出AO应为直流0V左右。
3, 旋转颤振调节电位器WAC，同时观察伺服输出交流电压，应当可以由0V连续升至交流4V左右。
4，伺服输出交流电压调至交流5V，将跳线器S3-1细胞芯片断开（OFF），伺服输出交流电压应为0V。
5，重新将跳线器S3-1接通（ON），将伺服输出交流电压调至交流1V
D，放大环节调试
通过选择增益跳线器S1可以将回路增益设为：1倍,2倍,3倍,4倍（注意，出厂增益设为：1）。
Attention: K * 1 - k * 4 line jumping device is all short while connecting, the proportion is gained minimumly, is about 0.2 times.
* 1 k - k * 4 device of line jumped when the all disconnection, it is most heavy for proportion to gain, about 12 times.
K5 jumps the line device to connect short: Give and control the signal in the servo card definitely;
Disconnection : The controller gives and controls the signal definitely ' It is the disconnection while dispatching from the factory)
w5: Controlled the signal 4 in the servo card definitely- 20mA regulates the potentiometer
w6: Become, give, export zero of VO2 adjust the potentiometer
w10: Change and send and export VO2 full location and adjust the potentiometer
K1 jumps the line device to connect short: Output flutter ' Connect for being short when being dispatched from the factory)
Disconnection: There is no flutter to export
KOPC jumps the line device:
Short to answer me +: OPC export to most electric current more while being servo at the movement; (lack connect by I at not dispatching from the factory +)
Connect I- short: OPC export the reverse most loud electric current while being servo at the movement
Debug the step in static behavior:
A.Check to jump line device produce the factory acquiescence position all at first
