Chapter 5 Configuring the PowerSmart+ PQM General Meter Setup
PowerSmart+ Power Quality Meter 87
Using Power Software
Select General Setup from the Meter Setup menu, and then click on the
Control/Alarm Setpoints tab.
The following table lists the available setpoint options.
Table 15: Setpoint Options
Option Range Description
Trigger parameter See Appendix C 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 digital 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 C The action performed when the setpoint
expression is evaluated to true (the setpoint
is in operated state)

Using Numeric Triggers
For numeric (analog) triggers, you can 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. The trigger
thresholds are specified in primary units.
