S&C Instruction Sheet 1023-510 23
Installing the Capacitor Control
NOTICE
The capacitor bank
Close command is blocked for a period of 5 minutes after an Open
command . This delay provides time for the capacitor charge to bleed off . For more
details, see the “Switching Capacitor Bank” section in Instruction Sheet 1023-540,
“S&C IntelliCap Plus Automatic Capacitor Control:
Operation .”
STEP 4. Check Neutral Current/Voltage indication on the faceplate LCD screen.
(a) If neutral sensing is installed, the LCD display shows: ** UNIT OK** .
(b) Press the ENTER faceplate button twice. The LCD display will show: ** DATA ** .
(c) Use the NEXT faceplate button to scroll the data to: NCAlrmLvl= , and note the
value displayed.
(d) Use the NEXT faceplate button to scroll the data to: NeutRmsAmps= . If the
displayed value is greater than the NCAlrmLvl= value, check the capacitor bank
for a problem indicated by neutral voltage or neutral current. This condition must
be corrected before the IntelliCap Plus control will operate correctly.
STEP 5. Set the control to Local and Manual mode.
At this stage the capacitor control is ready for Local , Manual operation mode.
WARNING
Be sure to leave the control in
Local (not Remote) and Manual (not Automatic) mode
until the software in the capacitor control is set up for this installation . Otherwise unex-
pected operation may occur .
If this capacitor control uses a radio, check that the radio has power.
A UtiliNet Radio should have a blinking pilot light. For most installations, the radio is
installed in the enclosure door.
The IntelliCap Plus control has two remote communication ports. When used with suitable
communication equipment and protocols, you can remotely monitor and control the
capacitor control installation.
S&C supports the IntelliCap Plus control with a variety of communication hardware
options and software protocols.
Supported manufacturers and hardware options include the following:
• SpeedNet™ Radio
• UtiliNet® Radio
• Cellnet® Radio
• Microwave Data Systems
• Hayes™ compatible modems
• Cellular transceivers
• Fiber-optic transceivers
For other options, contact S&C Electric Company.
DNP 3.0 is the sta nda rd protocol for the IntelliCap Plus control. Other
protocol options are:
• PG&E SCADA (Cooper 2179)
• Landis & Gyr Telegyr 8979
• Other (contact S&C)
All 8-bit, asynchronous SCADA protocols (at up to 9600 BAUD) are handled directly by
control software.
Most types of communication equipment can be mounted inside the capacitor
control enclosure (in the door). This eliminates clutter and provides better reliability for
the installation.
