报警继电器：当开关输入分配给报警继电器时，开关状态的变化产生报警条件，报警继电器激活。•脉冲输入1/2/3/4：当开关输入被指定为脉冲输入计数器时，当输入被配置为常开时，PQM计数从打开到关闭的转换次数，当输入配置为常闭时，PQ计数从关闭到打开的转换次数。PQM读取开关所需的最小脉冲宽度为150 ms。因此，PQM读取一个脉冲时，开关输入必须处于非活动状态（关闭/打开）至少150 ms，然后处于活动状态（打开/关闭）至少150毫秒。更多详细信息，请参阅第13页第1.3节：规范新需求周期：PQM可通过将开关输入分配给新需求周期来用于减载。
ALARM RELAY: When a switch input is assigned to the alarm relay, a change in the switch status produces an alarm condition and the alarm relay activates. • PULSE INPUT 1 / 2 / 3 / 4: When a switch input is assigned as a pulse input counter, the PQM counts the number of transitions from open to closed when the input is configured as normally open and closed to open when the input is configured as normally closed. The minimum pulse width required for the PQM to read the switch is 150 ms. Therefore, for the PQM to read one pulse, the switch input must be in its inactive state (closed/open) for a minimum of 150 ms then in its active state (open/ closed) for another 150 ms. See Section 1.3: Specifications on page –13 for more details. • NEW DEMAND PERIOD: The PQM can be used for load shedding by assigning a switch input to a new demand period.
