Docket No. 50-382 Potentially Reportable Incident No. 21
" Pressure Transzitter Lift-Off Voltage" Dest Mr. Seyfrit:
The sui. ject deficiency describes a lif tof f-voltage problem for Rosemount 1153A tran;,=itters. The device will not start up for certain combinations of power supply voltage, tero suppression, ambient temperature, etc.
In Waterford SES Unit No. 3 applications, the voltage provided to the current loop of the transmitter is 40 volts dc. Since the lif tof f-voltage problem does not occur if the power supply voltage exceeds 30 volts, we do no.t believe that this failure is a reportable deficiency under 10CFR50.55e.
Yours verf truly, 6
