Chapter 8—Input / Output PowerLogic™ PM5500 series user manual
Energy pulsing
You can configure the meter’s alarm / energy LED or one of the digital outputs for
energy pulsing applications.
NOTE: The alarm / energy pulsing LED on the PM5561 is permanently set for energy
pulsing and cannot be disabled or used for alarms.
When set to detect alarms, the LED blinks to indicate an alarm condition. See “Alarm
priorities” on page 96 for a description of the LED behavior based on different alarms.
When the LED is set to energy pulsing, the meter sends a readable pulse or signal
based on the measured energy. This pulse can be used for accuracy verification or as
an input to another energy monitoring system. The meter uses the pulse constant
setting in pulses per k_h to determine the frequency and number of pulses sent to the
LED (where k_h = kWh, kVARh or kVAh depending on the energy parameter selected).
The LED setup screen allows you to configure the alarm / energy pulsing LED for
alarming or energy pulsing applications.
