3/4.8.3 UNDERVOLTAGE PROTECTION 4.16 kV EMERGENCY BUS UNDERVOLTAGE PROTECTION LIMITING CONDITION FOR OPERATION 3.8.3.1 The 4.16 kV Emergency Bus Undervoltage Protection instrumen-tation shown in Table 3.8-1 shall be OPERABLE with their trip set-points set consistent with the values shown in the Trip Setpoint col-umn of Table 3.8-2.
i APPLICABILITY: As shown in Table 3.8-1.
ACTION:
4 With a 4.16 kV Emergency Bus Undervoltage Protection instru-a.
mentation channel trip setpoint exceeding the value shown in Table 3.8-2, declare the channel inoperable and apply the applicable ACTION requirement of Table 3.8-1 until the channel is restored to OPERABLE status with the trip setpoint adjusted consistent with the Trip Setpoint value.
b.
With a 4.16 kV Emergency Bus Undervoltage Protection instrumen-tation channel inoperable, take the ACTION shown in Table 3.8-1.
SURVEILLANCE REQUIREMENTS 4.8.3.1 Each 4.16 kV Emergency Bus Undervoltage Protection instrumen-tation chan el shall be demonstrated OPERABLE by the performance of the CHANNEL CALIBRATION and CHANNEL FUNCTIONAL TEST operations during the modes and at the frequencies shown in Table 4.8-1.
