Monitoring Exceedance/Deviation Of Load - MDT AMI series Technical Manual

Technical Manual Switch Actuators AMI/AMS
The total power meter function calculates the sum of the active energy of all channels at which the
power meter function was activated. The object can be selected as well to Wh as to kWh.
Via the parameter "Sending object value" can be determined, if the object sends its current value
only on request or in adjustable time intervals. Furthermore it can be adjusted, if the power meter
shall hold its current value or if they shall set to zero again after a download.
The total power meter has in contrast to the power meter for the single channels no reset object.
The total power meter function calculates always the sum of all single channels. So, a reset of all
single channels causes automatically a reset of the total power meter.
The communication object for the total power meter function is shown at the following chart:

4.6.5 Monitoring exceedance/deviation of load
An observation of the load can be activated for every channel for an exceedance of a comparable
worth as well as for a deviation of this worth. The total current measurement can only observe a
exceedance. The possible settings are shown at the following illustration:
