Number: HRC-C-007
Type: Constraint
Original Date: 1/31/97
Subsystem: HRC
Subject: HRC High Voltage and Electronic Calibration Mode
Source: Informal CARD inputs, e-mail, M. Juda, 1/28/97
CRL Statement:
HRC high voltages must be commanded OFF prior to turning ON the internal
electrical calibration mode.
CRL Rationale/Justification:
HRC sensitivity to high voltage when entering the calibration mode is derived
from the HRC design.
CRL Impact:
HRC high voltage switching transients will damage the HRC preamplifier
inputs.
Recommended Action:
Incorporate into the Systems and Operations Procedures, with ASC providing
the inputs.
