4.2.6 Peak Demand of This Month and Last Month
The PMC-630E calculated 3-phase Current, ∑kWh, ∑kvar and ∑kVA peak demand of This Month and
Last Month. All Max/Min data can be accessed through communication.
4.3 Setpoints
The PMC- PMC-630E comes standard with 9 user programmable setpoints which provide extensive
control by allowing a user to initiate an action in response to a specific condition. Typical setpoint
applications include alarming, fault detection and power quality monitoring.
The alarm symbol
at the right side of the LCD display is lit if there are any active Setpoints. The
setpoints can be programmed over communications and have the following setup parameters:
Setpoint Type:
Specify the monitoring condition – Over Setpoint, Under Setpoint, or Disabled.
1)
Setpoint Parameter:
Specify the parameter to be monitored. Table 4-3 below provides a list of Setpoint
Parameters.
2)
Setpoint Active Limit
:
Specify the value that the setpoint parameter must exceed for Over Setpoint or go below for
Under Setpoint for the setpoint to become active.
3)
Setpoint Inactive Limit
:
Specify the value that the setpoint parameter must go below for Over Setpoint or exceed for
Under Setpoint for the setpoint to becomes inactive.
4)
Setpoint Active Delay
:
Specify the minimum duration that the setpoint condition must be met before the setpoint
becomes active. An event will be generated and stored in the SOE Log. The range of the
Setpoint Active Delay
for the Standard Setpoint is between 0 and 9,999 (seconds).
5)
Setpoint Inactive Delay
:
Specify the minimum duration that the setpoint Return condition must be met before the
setpoint becomes inactive. An event will be generated and stored in the SOE Log. The
range of the
Setpoint Active Delay
for the Standard Setpoint is between 0 and 9,999
(seconds).
6)
Setpoint Trigger 1 and Setpoint Trigger 2
:
Specify what action the setpoint will take when it becomes active. Table 4-4 below provides
a list of Setpoint Triggers.
The PMC-630E provides the following Setpoint Parameters:
