16 S&C Instruction Sheet 1023-550
Using IntelliLink Software to Locate Problems
Model Number
This field shows the model number of this control.
Control Software Revision
This field shows the S&C name of the control software version present in this control, for
example PCSD100S.
Serial Number
This field shows the serial number of the capacitor control.
Alarm Status button
This button takes you to the
Alarm Status
screen. When any alarms are presently active,
the text on the button flashes.
Present Conditions
Except for the
Temperature
value, these fields are the true RMS amplitude measurements
for the three phases on the feeder. The capacitor control takes a measurement
every 0.3 seconds. It then averages four measurements and displays the 1.2-second
averaged value. For a more detailed explanation of these fields, see Instruction Sheet 1023-
530, “S&C IntelliCap® Plus Automatic Capacitor Control:
Setup
.”
The
Temperature
value is the present air temperature. The temperature sensor is located
on the bottom of the control enclosure.
Neutral Sensor (Total RMS)
This field displays the total RMS value for neutral sensing, when installed. Neutral
sensing alarming uses the Total RMS value when the
Neutral Sensing Alarming (Current
or Voltage)
setpoint on the IntelliLink
Setup>Neutral Sensing
screen, is set to
Total RMS
mode. When the control does not have neutral sensing installed, this field displays “n/a.”
Neutral Sensor (Fundamental)
This field displays the fundamental (60-Hz) component of the neutral sensing value, when
installed. Neutral sensing alarming uses the fundamental value when the
Neutral
Sensing Alarming (Current or Voltage)
setpoint on the IntelliLink
Setup>Neutral
Sensing
screen is set to
Fundamental
mode. When the control does not have neutral
sensing installed this field displays “n/a.”
Voltage Override
This field shows whether a voltage-override condition is presently active.
SCADA Override
This field shows whether the
SCADA Override
feature is in the
Enabled
state via SCADA
command.
Error Conditions
When the control detects an alarm or an error condition, this field displays the message
“See Alarm Status.” When this message is present, see the
Alarm Status
screen for more
information.
Current Flow Direction, Power kvars, and Power Factor (var controls
only)
The control measures the phase angle between the voltage and current waveforms. If the
phase angle is between ±90 degrees, the
Current Flow Direction
field shows “Normal.”
The control calculates and displays the measured power factor and measured 3-phase
kvars. For controls with single-phase sensing, the displayed power kvars value is the
calculated single-phase kvars value times three.
When the phase angle is between -90 degrees (the same as +270 degrees) and 0 degrees,
the power factor and kvars are given a negative sign, which indicates that the current wave-
form is leading the voltage waveform.
