TABLE 3.3-3 (Continued)
TABLE NOTATION (a) Trip function may be bypassed when pressurizer pressure is < 1750 psia; bypass shall be automatically removed when pressurizer pressure is 21750 psia.
(b) An SIAS signal is first necessary to enable CSAS logic, (c) Trip function may be bypassed below 600 psia; bypass shall be automatically removed at or above 600 psia.
(d) Each channel has two sensors, high radiation level on either sensor will initiate containment purge valve isolation.
(e) Trip may be bypassed during testing pursuant to Special Test Exception 3.10.3.
(f) The logic combinations of A/C and B/D do not provide a SRAS trip condition.
