TABLE 3.3-4 (Continued) 1 TABLE NOTATION (1) Value may be decreased manually, to a minimum of greater than or equal to 300 psia, as pressurizer press.ure is reduced, provided the margin between the pressurizer and this value is maintained at less than or equal to 400 psia;* the setpoint shall be increased automatically as pressurizer pressure is increased until the trip setpoint is reached.

Trips may be bypassed when pressurizer pressure is < 400 psia. Bypass shall be automatically removed before pressurizer pressure exceeds 500 psia (the corresponding bistable allowable alue is 5 472 psia).
