keyword=Right Q1/D1 He read back circuit
The right Q1 He readback circuit has been converted from 2-10 V to 0-10V
to the hall A tools page (1313 ch 18). The cryo readback is still 4-20
ma converted to 2-10V at cryo's cross connect rack. Both circuits are
isolated with Pheonix isolation modules.
A UPS has been installed for the Dipole quench detection and Dipole He
level circuits to provide a dedicated power source for the Wang
protection circuit. The lead flow circuits are still routed through the
wang protection circuit, Securing power on the Wang protection Circuit
UPS.... WILL FAST DUMP THE MAGNET POWER SUPPLY.
