Field Installation
Using the Pulse Output Port Function
Pulse output is used to generate pulses for external devices such as data loggers that can accept pulses
but do not have BACnet or Modbus capability. The PowerScout 24 can generate pulses based on
accumulated value(s) such as system kWh, system kVARh, and system kVAh. When a pulse is generated
by the meter, the pulse LED will briefly flash, otherwise it will remain dark.
When in Modbus, the pulse output is scaled by the Modbus data scalar register 44602. When in BACnet,
the pulse output is scaled by the CT Pulse Scalar object 12030. The pulse scalar table is the same as the
Modbus data scalar table. For example, when the data scalar is set to 3, each pulse will represent
.1kWh, .1kVAh and .1kVARh.
