产品详细资料
•强制输出1至8:选择“通电”以强制输出1(8)进入通电状态,或选择“断电”以强制输入1(8。此设定点仅在启用输出继电器测试时才可操作。•强制自检RLY:选择“通电”以强制自检继电器进入通电状态,选择“断电”以强制进入断电状态。此设定点仅在输出继电器测试功能启用时才可操作。745能够超越模拟转换器输出的正常功能,迫使每个输出达到其输出范围的任何水平。启用此功能可打开测试模式LED,并断开自检继电器的电源。•强制模拟输出功能:选择“启用”以启用模拟输出测试并覆盖模拟输出正常操作。此设置点在通电时默认为“Disabled”(禁用)。•FORCE ANALOG OUT 1(7)(强制模拟输出1(7。例如,如果模拟输出范围已编程为4至20 mA,则输入100%输出20 mA,0%输出4 mA,50%输出12 mA。只有启用模拟输出测试时,此设置点才可操作。模拟功能允许根据编程条件测试继电器的功能,而无需外部交流电压和电流输入。输入电流和电压、相位角和系统频率等系统参数作为设定点。当置于模拟模式时,继电器暂停读取实际交流输入,并生成表示编程相量的样本。这些样本用于所有计算和保护逻辑。启用此功能将关闭在用LED,打开测试模式LED,并使自检继电器断电。
• FORCE OUTPUT 1 to 8: Select “Energized” to force output 1(8) to the energized state or “De-energized” to force output 1(8) to the de-energized state. This setpoint is only operational when output relay testing is enabled. • FORCE SELF-TEST RLY: Select “Energized” to force the self-test relay to the energized state and “De-energized” to force to the de-energized state. This setpoint is only operational while the output relay testing feature is enabled.The 745 has the ability to override the normal function of analog transducer outputs, forcing each to any level of its output range. Enabling this feature turns the Test Mode LED on and de-energize the self-test relay. • FORCE ANALOG OUTPUT FUNCTION: Select “Enabled” to enable the analog output testing and override the analog output normal operation. This setpoint defaults to “Disabled” at power on. • FORCE ANALOG OUT 1(7): Enter the percentage of the DC mA output range of analog output 1(7). For example, if the analog output range has been programmed to 4 to 20 mA, entering 100% outputs 20 mA, 0% outputs 4 mA, and 50% outputs 12 mA. This setpoint is only operational if analog output testing is enabled.The simulation feature allows testing of the functionality of the relay in response to programmed conditions, without the need of external AC voltage and current inputs. System parameters such as currents and voltages, phase angles and system frequencyare entered as setpoints. When placed in simulation mode, the relay suspends reading actual AC inputs and generates samples to represent the programmed phasors. These samples are used in all calculations and protection logic. Enabling this feature will turn off the In Service LED, turn on the Test Mode LED, and de-energize the self-test relay.
