MAGNET POWER SUPPLY SYSTEM 8500
3.3.5.
Two level value set.
The two level value set function enables the power supply to quickly switch between two arbitrary
given set points (this ab SW version SCS 114). For bipolar power supplies e.g. it could be between
any positive and negative value or for unipolar power supplies. it could be between any positive
value and zero.
The two level value function, which is always enabled, is partially implemented in HW (inside the
FPGA) and SW. If this function is not used, set register 0 will be default selected making the system
both HW and SW compatible with previous versions.
The two levels can either be selected through SW from an added parameter in the ‘da 0’ command
or through HW using the ‘SYNC’ line. If the ‘SYNC’ line is used for the two level select, it must
first be enabled by setting ‘AUX2 bit 5' to “1" thereby deselecting its use for ramp synchronization
purposes.
The two level function is shown from the simplified block schematic below:
