It has been detern Lned that thereplacementcoiksbeinginstalledin response to IE Bul) Letin 79-01A are rated at 120 V DC with a normal opera. ting range of 102 to 126 volts. The statilan batrcry voltage l
ranges frca 107 cci 137 volts. The coils could potentially f ail if they were mai.ntaia'ni at voltages above their not=al operating range.
4 ASCO.polenoid Valv ts (model HT 830037RF) are used on 11 outside con-tainannt isol'ation volves which une ASCO solenoids for pilot cperators.
7RF maximum saf e working pre'sure is 75 psi. The ASCO'model HT 830Cp:h supplies the ASCO solenoid' valves is 85 to 95 psi.
e l
instrument air wht This overpressuria ttion could affect the solenoid valves' performance, potentially preven ;ing the containment isolatioh valve f rom performing i
