Chapter 7—Alarms

This section describes the alarm features on PM5300 series Power and Energy meters.

About Alarms

The ! icon appears in the upper-right corner of the meter display when an alarm is active.

If the energy/alarm LED has been configured for alarms, the energy/alarm LED flashes when an alarm is active. See “Alarm / energy pulsing LED setup” on page 60 for more information.

The power meter maintains a counter for each alarm to help keep track of the total number of occurrences (see Figure 7–1).

Figure 7–1: Alarm Counters

If you make changes to the basic power meter setup, all alarms are disabled to prevent undesired alarm operation. Confirm alarm configuration and enable required alarms.

NOTE: Only alarms that apply to the selected power system configuration can be enabled.

The available alarms for this power meter are described in the following sections.

1-Second Alarms

The power meter has 29 standard 1-second over/under alarms. See Table 7–1for a complete list.

Use the display to configure 1-second alarms with the following values:

•Enable—disable (default) or enable

•Pickup Setpoint (magnitude)

•Pickup Time Delay (in seconds)
