(a) A channel is OPERABLE with an actual Trip Setpoint value outside Its calibration tolerance band provided the Trip Setpoint value Is conservative vwth respect to Is associated Allowable Value and the channel Is re-adjusted to within the established calibraton tolerance band of the Nominal Trip Setpoint. A Trip Setpoint may be set more conservative than the Nominal Trip Setpoint as necessary in response to plant conditions.
(g) Above the P-7 (Low Power Reactor Trips Block) nterlock.
