CHAPTER 5: SETTINGS CONTROL ELEMENTS
C70 CAPACITOR BANK PROTECTION AND CONTROL SYSTEM – INSTRUCTION MANUAL 5-265
5
CAP 1 LCL SET MAN — Similar to the CAP LCL SET AUTO setting, but selects manual mode.
CAP 1 TRIP 1(6) — Selects up to six FlexLogic operands to activate the CAP 1 BKR TRIP operand, no matter what control modes
prevail. Expected to be set to the appropriate protection element operate operand.
CAP 1 SWITCH TO MANUAL ON TRIP — Allows control of the auto/manual mode when issuing a trip command. When set to
“Yes,” the element switches to manual mode upon tripping the bank from protection.
CAP 1 AUTO CTRL EN — Selects a FlexLogic operand to enable automatic open/close control. It is expected to be set to CAP 1
IN AUTO to obtain the baseline functionality, but variations are possible.
CAP 1 MAN CTRL EN — Similar to previous setting, but enables manual controls. Expected to be set to CAP 1 IN MAN.
CAP 1 REMOTE OPEN — Selects a FlexLogic operand to activate the CAP 1 BKR TRIP operand when both remote and manual
control are enabled. It is expected to be set to a virtual input, and that the contact output wired to the capacitor breaker
trip coil is set to CAP 1 BKR TRIP.
CAP 1 LOCAL OPEN — Similar to previous setting, but requires both local and manual control to be enabled. Expected to be
set to a pushbutton “on” operand.
CAP 1 AUTO OPEN — Similar to previous setting, but requires automatic control to be enabled. Expected to be set to the open
command of the voltage regulator either built-in or customer via FlexLogic.
CAP 1 BKR OPEN 52b — Selects a FlexLogic operand that cancels the trip seal-in. Expected to be set to the contact input to
which a contact is wired that is closed when the capacitor breaker is open. When both 52a and 52b contacts are used for
security, the appropriate filtering logic possibly including discrepancy alarming can be programmed in FlexLogic, and the
resulting virtual output can be configured under this setting.
CAP 1 TRIP SEAL-IN DELAY — Sets a maximum trip seal-in duration for where the CAP 1 BKR OPEN 52b setting is not configured
or fails to operate.
CAP 1 REMOTE CLOSE — Similar to the CAP 1 REMOTE OPEN setting, but closes the breaker.
CAP 1 LOCAL CLOSE — Similar to the CAP 1 LOCAL OPEN setting, but closes the breaker.
CAP 1 AUTO CLOSE — Similar to the CAP 1 AUTO OPEN setting, but closes the breaker.
CAP 1 BKR CLSD 52a — Similar to the CAP 1 BKR OPEN 52b setting, but cancels the close seal-in, and is expected to be set to a
contact that is closed when the breaker is closed. The selected operand also triggers the
CAP 1 DISCHARGE TIME. When both
52a and 52b contacts are used for security, the appropriate filtering logic possibly including discrepancy alarming can be
programmed in FlexLogic, and the resulting virtual output can be configured under this setting.
CAP 1 CLOSE SEAL-IN DELAY — Sets a maximum close seal-in duration for where the CAP BKR CLSD 52a setting is not
configured or fails to operate.
CAP 1 DISCHARGE TIME — Sets a time delay that inhibits closing after the bank has been switched out-of-service (the CAP
BKR CLSD 52a
setting goes low or trip command terminates) until the bank has had time to discharge any trapped charge.
The correct value for this setting depends on the specifics of the capacitor installation.
CAP 1 BKR CLOSE BLK — Selects a FlexLogic operand that triggers the CAP 1 BKR CLOSE interlock logic. Its signal is expected
to originate from capacitor breaker trips external to the relay, and thus not otherwise able to block relay closing (for
example, from the opposite group's capacitor protection).
CAP 1 CLS OVERRIDE — Selects a FlexLogic operand that overrides all inhibits for the breaker close command and allows the
CLOSE command to be issued from any source as per the logic diagram.
