报警继电器•报警操作：术语“故障安全”和“非故障安全”在PQM中定义如上。如果PQM因失去控制电源而无法运行时需要报警，请选择故障保护操作。否则，选择非故障保护。•报警激活：如果仅在出现报警时才需要报警指示，请选择解锁。一旦报警条件消失，报警和相关信息将自动清除。为确保确认所有报警，请选择“锁定”。即使报警条件不再存在，也只能通过按键或通过计算机发送重置命令来清除报警继电器和消息。
Alarm Relay • ALARM OPERATION: The terms ‘failsafe’ and ‘non-failsafe’ are defined above as implemented in the PQM. If an alarm is required when the PQM is not operational due to a loss of control power, select failsafe operation. Otherwise, choose non-failsafe.• ALARM ACTIVATION: If an alarm indication is required only while an alarm is present, select unlatched. Once the alarm condition disappears, the alarm and associated message automatically clear. To ensure all alarms are acknowledged, select latched. Even if an alarm condition is no longer present, the alarm relay and message can only be cleared by pressing the key or by sending the reset command via the computer.
