GE DS3800HNMB1B1A调制解调器卡
选择AUX1、AUX2或AUX3激活相应的辅助继电器，但不显示任何信息。AUX1、AUX2和AUX3选择用于过程控制。当PQM时钟时间等于或超过DROPOUT time设置时，所选继电器将断电。•拾取时间：当PQM时钟时间等于或超过此设置点中指定的时间时，时间继电器设置点中分配的继电器通电。按照以下示例设置拾取时间。延迟时间：当PQM时钟时间等于或超过此设置点中指定的时间时，时间继电器设置点中分配的继电器断电。按照上面的示例设置DROPOUT TIME。•串行通信1/2故障报警延迟：如果需要与外部主机失去通信以激活报警继电器，请选择5到60秒范围内的时间延迟。在这种情况下，在选定的时间延迟内，RS485通信端口上没有通信轮询将产生报警条件。如果未使用通信或认为通信不重要，则禁用此警报。该报警在前RS232端口上不可用。
Selecting AUX1, AUX2 or AUX3 activates the appropriate auxiliary relay but no message is displayed. The AUX1, AUX2 and AUX3 selections are intended for process control. The selected relay will de-energize when the PQM clock time equals or exceeds the DROPOUT TIME setting. • PICKUP TIME: The relay assigned in the TIME RELAY setpoint energizes when the PQM clock time equals or exceeds the time specified in this setpoint. Follow the example below to set the PICKUP TIME.DROPOUT TIME: The relay assigned in the TIME RELAY setpoint de-energizes when the PQM clock time equals or exceeds the time specified in this setpoint. Follow the example above to set the DROPOUT TIME.• SERIAL COM1/2 FAILURE ALARM DELAY: If loss of communications to the external master is required to activate the alarm relay, select a time delay in the range of 5 to 60 seconds. In this case, an absence of communication polling on the RS485 communication port for the selected time delay will generate the alarm condition. Disable this alarm if communications is not used or is not considered critical. This alarm is not available on the front RS232 port.
