CBC-8000 capacitor bank control description8 CBC-8000 capacitor bank control installation and operation instructions MN916001EN—October 2018 Eaton.com• ALARMS – Pressing the ALARMS button displays thealarms that are currently active. The active alarms may bescrolled through by using the  (Up) arrow and the (Down) arrow buttons. If the status indicator ALARMS LEDis flashing, one or more alarms are active in the control.The LED for the ALARMS button will illuminate when thisbutton is pressed.Row 3 – Reserved for future useThe buttons in row 3 are not currently used at this time.Control featuresThe CBC-8000 capacitor bank control offers the followingstandard 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 14Control securityThe control offers customer-programmable security codes tolimit control programming and viewing function access toauthorized personnel. The front panel Human-MachineInterface (HMI) includes a user-selected security code toaccess the settings. Plus, the ProView NXG software has itsown security levels for multiple-user access.Refer to the CBC-8000 capacitor bank control ProView NXGapplication software programming guide (MN916002EN) foradditional information regarding how to set and changepasswords.Password recoveryIf your password is lost, contact your local Eaton’s CooperPower series representative.Manual modeThe Manual operating mode allows manual control of thecapacitor bank using the TRIP and CLOSE buttons on thefront panel. When the control is in Manual mode, remote orautomatic operation of the capacitor bank is disabled.Note: The MANUAL LED illuminates when the control is inmanual operating mode.If the MANUAL button is pressed during the delay time of aremote or automatic control operation, the delay time isstopped and the pending operation is canceled.Pressing the MANUAL button places the control in Manualmode. The control will not accept remote Trip or Closecommands, or use site measurements to operate thecapacitor bank while in Manual mode. This is the highestpriority command for the CBC and it cannot be overridden byany other command to the CBC.Taking the CBC out of Manual mode can only be donethrough the front panel. No command from the ProView NXGsoftware or SCADA can change the operational mode fromManual.When the control is changed to the Remote or Automaticoperating mode, control based on local conditions is restoredas follows:• For Time control, a 2 minute timer starts when the controlleaves Manual mode and any close or trip operationrequested by the Time control strategy is delayed until thetimer expires. This timer only applies to Time control; itdoes not affect capacitor bank operation initiated by anyother control strategy.• For all other Auto control requests, a 30 second manualdelay timer is started when the control is removed fromManual mode. This is done as a safety measure to preventimmediate capacitor bank operation in case a track timer isset to a short time period. If a local condition startstracking, before the 30 second manual delay timer hasfinished, the remaining amount of time for the manualdelay timer is added to the tracking timer for the localcondition that is requesting the operation. This ensuresthat the manual delay timer is allowed to run for the entire30 second time period and that the track timer is allowedto run for its entire duration.Manual close delay timeThe manual close delay timer provides a delay from the timethat the manual CLOSE button is pressed to the time that themanual close operation is performed. This delay givesservice personnel time to move away from the capacitorbank before the switch actually closes. The CLOSE LEDblinks when the manual close delay timer is active.The manual close delay is programmable from 30 to 255seconds in 1 second increments.Remote modeThe Remote operating mode allows remote operation of thecapacitor bank using a serial or Ethernet SelectCommcommunication module or a local USB connection with theProView NXG software. Manual operation of the capacitorbank is disabled when the control is in Remote mode.However, automatic control is allowed when the control is inthe remote operating mode.When the control is in Remote mode, commands areaccepted from the Master StationNote: The REMOTE LED illuminates when the control is inremote operating mode.
