CBC-8000 capacitor bank control description
8 CBC-8000 capacitor bank control installation and operation instructions MN916001EN—October 2018 Eaton.com
• ALARMS – Pressing the ALARMS button displays the
alarms that are currently active. The active alarms may be
scrolled through by using the (Up) arrow and the
(Down) arrow buttons. If the status indicator ALARMS LED
is flashing, one or more alarms are active in the control.
The LED for the ALARMS button will illuminate when this
button is pressed.
Row 3 – Reserved for future use
The buttons in row 3 are not currently used at this time.
Control features
The CBC-8000 capacitor bank control offers the following
standard features:
• Control security on Page 8
• Manual mode on Page 8
• Remote mode on Page 8
• Automatic mode on Page 9
• Alarming on Page 13
• Priority table control on Page 13
• Metering on Page 14
• Data logs on Page 14
Control security
The control offers customer-programmable security codes to
limit control programming and viewing function access to
authorized personnel. The front panel Human-Machine
Interface (HMI) includes a user-selected security code to
access the settings. Plus, the ProView NXG software has its
own security levels for multiple-user access.
Refer to the CBC-8000 capacitor bank control ProView NXG
application software programming guide (MN916002EN) for
additional information regarding how to set and change
passwords.

Manual mode
The Manual operating mode allows manual control of the
capacitor bank using the TRIP and CLOSE buttons on the
front panel. When the control is in Manual mode, remote or
automatic operation of the capacitor bank is disabled.
Note: The MANUAL LED illuminates when the control is in
manual operating mode.
If the MANUAL button is pressed during the delay time of a
remote or automatic control operation, the delay time is
stopped and the pending operation is canceled.
Pressing the MANUAL button places the control in Manual
mode. The control will not accept remote Trip or Close
commands, or use site measurements to operate the
capacitor bank while in Manual mode. This is the highest
priority command for the CBC and it cannot be overridden by
any other command to the CBC.
Taking the CBC out of Manual mode can only be done
through the front panel. No command from the ProView NXG
software or SCADA can change the operational mode from
Manual.
When the control is changed to the Remote or Automatic
operating mode, control based on local conditions is restored
as follows:
• For Time control, a 2 minute timer starts when the control
leaves Manual mode and any close or trip operation
requested by the Time control strategy is delayed until the
timer expires. This timer only applies to Time control; it
does not affect capacitor bank operation initiated by any
other control strategy.
• For all other Auto control requests, a 30 second manual
delay timer is started when the control is removed from
Manual mode. This is done as a safety measure to prevent
immediate capacitor bank operation in case a track timer is
set to a short time period. If a local condition starts
tracking, before the 30 second manual delay timer has
finished, the remaining amount of time for the manual
delay timer is added to the tracking timer for the local
condition that is requesting the operation. This ensures
that the manual delay timer is allowed to run for the entire
30 second time period and that the track timer is allowed
to run for its entire duration.
Manual close delay time
The manual close delay timer provides a delay from the time
that the manual CLOSE button is pressed to the time that the
manual close operation is performed. This delay gives
service personnel time to move away from the capacitor
bank before the switch actually closes. The CLOSE LED
blinks when the manual close delay timer is active.
The manual close delay is programmable from 30 to 255
seconds in 1 second increments.
Remote mode
The Remote operating mode allows remote operation of the
capacitor bank using a serial or Ethernet SelectComm
communication module or a local USB connection with the
ProView NXG software. Manual operation of the capacitor
bank is disabled when the control is in Remote mode.
However, automatic control is allowed when the control is in
the remote operating mode.
When the control is in Remote mode, commands are
accepted from the Master Station
Note: The REMOTE LED illuminates when the control is in
remote operating mode.
