HONEYWELL TC-CCR014卡件模块,TC-CCR014使用产品
在调整控制器增益之前，验证是否存在以下条件：1.HSS模块、液压执行器和LVDT变压器完整。
2.控制器增益设置为1（双列直插式开关S3极8为关闭）。有关控制器增益开关设置，请参阅表3-3。3、指定块地址中的校准命令位在S3中设置为0（正常操作）。4.S4中指定的块地址中的GO/HOLD位为设置为0（保持）。
5、汽轮机离线。要调整控制器增益：
HONEYWELL TC-CCR014卡件模块1.输入25%的职位需求（通过操作员界面），50%、75%和90%，打开阀门。观察
每个需求水平的节流阀。阀门应响应时，在任何需求水平上都不会出现波动。
2.输入25%的职位需求（通过操作员界面），50%、75%和90%，关闭阀门。观察
每个需求水平的节流阀。阀门应在每个需求水平上做出响应而不发生振荡。
3、止回阀操作。如果阀门运行平稳需求水平，继续。如果阀门振荡，请转至步骤7。
4、卸下HSS模块并提高控制器增益（开关2）切换到下一个设置。例如，如果增益为1（极8闭合），将增益更改为2（闭合极7，开路极8）。
Before tuning the controller gain, verify that the following con
ditions exist:
1. Calibration of the HSS module, hydraulic actuator and
LVDT transformer is complete.
2. The controller gain is set to 1 (dipswitch S3 pole 8 is
closed). Refer to Table 3-3 for controller gain switch settings.
3. The calibration command bit in the block address specified
in S3 is set to 0 (normal operation).
4. The GO/HOLD bit in the block address specified in S4 is
set to 0 (HOLD).
5. The turbine is off-line.
To tune the controller gain:
1. Enter position demands (via the operator interface) of 25%,
50%, 75% and 90%, opening the valve. Observe the response of
the throttle valve at each demand level. The valve should
respond without oscillating at any level of demand.
2. Enter position demands (via the operator interface) of 25%,
50%, 75% and 90%, closing the valve. Observe the response of
the throttle valve at each demand level. The valve should
respond without oscillating at each level of demand.
3. Check valve operation. If the valve operates smoothly at all
demand levels, continue. If the valve oscillates go to Step 7.
4. Remove the HSS module and raise the controller gain
(switch 2) to the next setting. For example, if the gain is 1 (pole
8 is closed), change the gain to 2 (close pole 7, open pole 8).
