Chapter 5 Configuring the PowerSmart Socket PQM General Meter Setup
PowerSmart Socket Power Quality Meter 99
Using Control Setpoints
The PowerSmart Socket PQM has an embedded logical
controller that runs different actions in response to user-
defined internal and external events. Unlike a PLC, the
PowerSmart Socket PQM uses a simplified programming
technique based on setpoints that allows the user to define a
logical expression based on measured analog and digital
values that produces a required action.
The PowerSmart Socket PQM provides 16 control setpoints
with programmable operate and release delays. Each setpoint
evaluates a logical expression with up to four arguments
using OR/AND logic. Whenever an expression is evaluated as
“true”, the setpoint performs up to four concurrent actions
that can send a command to the output relays, increment or
decrement a counter, or trigger a recorder.
To program the setpoints, select General Setup from the
Meter Setup menu, and then click on the Control/Alarm
Setpoints tab.
The available setpoint options are described in the following
table:
Option Format/Range Description
Setpoint Triggers
OR/AND OR, AND The logical operator for the trigger
Input group The trigger parameter group (see Appendix A)
Trigger
parameter The trigger parameter that is used as an argument
in the logical expression (see Appendix A)
