安装负载共享模块
设置和校准简介在发电机组上安装负载共享模块后，使用此校准程序，以获得负载共享期间所需的操作特性。1.检查端子15、16、17和18上是否安装了正确的跳线，以匹配电压互感器二次电压。参见工厂接线图（图1-3）。2.从负载分配线路端子10和11以及端子24和25处的SPM-A同步器（如果使用）上取下电线。3.通过短路端子13和14选择同步操作。警告-启动准备在启动发动机、涡轮机或其他类型的原动机时紧急停机，以防止失控或超速，生命损失或财产损失。4.根据发动机制造商的说明启动发动机。将发动机调整到额定转速。对发电机组施加全负荷。注：最准确的校准是在满载时进行的。但是，如果发电机组不能满负荷运行，则应在低于满负荷的情况下运行，并按比例降低本校准程序中给出的电压读数。
发电机组
以100 kW的功率运行一台200 kW的发电机组，并将此校准程序中给出的所有电压除以2。如果以这种方式减少负载，请确保在整个校准过程中以相同的量减少负载。5.顺时针完全设置负载增益电位计。6.检查端子22和23之间的负载信号电压。调整负载增益电位计的6.0 Vdc信号。如果无法获得该电压，则将负载信号设置为尽可能接近6 Vdc。7.从发电机组上卸下负载。8.检查端子22和23之间的电压。该电压应为0.0±0.25 Vdc。如果该电压不正确，则说明负载分配模块有故障或发电机上可能仍有负载。负载共享模块手册26011 12相位检查警告-高电压开路CT（电流互感器）两端的高电压可能导致死亡或严重伤害。
Installing the Load Sharing Module
Setup and Calibration IntroductionAfter installing the load sharing module on the generator set, use this calibration procedure to obtain the required operating characteristics during load sharing. 1. Check whether correct jumpers are installed on terminals 15, 16, 17 and 18 to match the secondary voltage of voltage transformer. Refer to the factory wiring diagram (Figure 1-3). 2. Remove the wires from the SPM-A synchronizer (if used) at terminals 10 and 11 of the load sharing line and terminals 24 and 25. 3. Select synchronous operation through short-circuit terminals 13 and 14. WARNING - STARTING PREPARATION Emergency shutdown when starting the engine, turbine, or other type of prime mover to prevent runaway or overspeed, loss of life, or property damage. 4. Start the engine according to the engine manufacturer's instructions. Adjust the engine to the rated speed. Apply full load to the generator set. Note: The most accurate calibration is performed at full load. However, if the generator set cannot be operated at full load, it should be operated below full load and the voltage readings given in this calibration procedure should be reduced proportionally.
Generator Set
Run a 200 kW generator set at 100 kW and divide all the voltages given in this calibration procedure by 2. If the load is reduced in this way, ensure that the load is reduced by the same amount throughout the calibration process. 5. Fully set the load gain potentiometer clockwise. 6. Check the load signal voltage between terminals 22 and 23. Adjust the 6.0 Vdc signal of the load gain potentiometer. If this voltage is not available, set the load signal as close to 6 Vdc as possible. 7. Remove the load from the generator set. 8. Check the voltage between terminals 22 and 23. The voltage should be 0.0 ± 0.25 Vdc. If the voltage is incorrect, the load distribution module is faulty or there may still be a load on the generator.
