Chapter 4 Power Software Configuration tool General Meter Setup
48 Multi-Mon Multiple Circuit Energy Monitor
This setup allows configuring setpoints for each individual submeter. It can
be read and changed via the corresponding submeter’s address.
To program the setpoints for a submeter, select General Setup from the
Meter Setup menu, and then click on the Control/Alarm Setpoints tab.
The following table describes the setpoint options.
Option Option Option Option Range Range Range Range Description Description Description Description
Trigger
parameter See Appendix D The trigger parameter that is used as an argument in
the logical expression
Operate limit The threshold (in primary units) at which the
conditional expression would be evaluated to true. Not
applicable for time triggers.
Release limit The threshold (in primary units) at which the
conditional expression would be evaluated to false.
Defines the hysteresis for analog triggers. Not
applicable for digital triggers.
Operate delay 0.1-999.9 sec The time delay before operation when the operate
conditions are fulfilled
Release delay 0.1-999.9 sec The time delay before release when the release
conditions are fulfilled
Action See Appendix D The action performed when the setpoint expression is
evaluated to true (the setpoint is in operated state)
Using Numeric Triggers Using Numeric Triggers Using Numeric Triggers Using Numeric Triggers
For numeric (analog) triggers, a setpoint allows you to specify two thresholds
for each trigger to provide hysteresis (dead band) for setpoint operations.
The operate limit defines the operating threshold, and the second release
limit defines the release threshold for the trigger. If you do not want to use
hysteresis for the trigger, set the release limit to the same as the operate
limit.
Using Time Triggers Using Time Triggers Using Time Triggers Using Time Triggers
If you want the setpoint actions to be synchronized with the clock, for
example, to provide recording interval data, use the minute time interval
trigger that generates periodic events synchronized with the device clock.
